Dopamine correlates of neurological and psychological status in untreated Parkinsonism. (1/6239)

Thirty-seven untreated Parkinsonism patients showed significant positive correlations among decreased excretion of free dopamine, MMPI scores indicative of schizophrenic-like looseness of thinking, and the severity of all Parkinsonism signs except tremor. The data could indicate that abnormalities of dopamine metabolism may underlie both the motor and mental abnormalities of Parkinsonism.  (+info)

2,3 diphosphoglycerate in Parkinson's disease. (2/6239)

The red cell 2,3 DPG, the most important factor for oxygen delivery in the tissues, was found to be increased in Parkinsonism patients compared with controls. The aging process seems not to be a factor in the increased 2,3 DPG concentration. Other factors relevant to raised 2,3 DPG level such as physical activity, increased oxygen requirements, and metabolic changes are discussed.  (+info)

Visual control of locomotion in Parkinson's disease. (3/6239)

The effect of placing parallel lines on the walking surface on parkinsonian gait was evaluated. To identify the kind of visual cues (static or dynamic) required for the control of locomotion, we tested two visual conditions: normal lighting and stroboscopic illumination (three flashes/s), the latter acting to suppress dynamic visual cues completely. Sixteen subjects with idiopathic Parkinson's disease (nine males, seven females; mean age 68.8 years) and the same number of age-matched controls (seven males; nine females, mean age 67.5 years) were studied. During the baseline phase, Parkinson's disease patients walked with a short-stepped, slow velocity pattern. The double limb support duration was increased and the step cadence was reduced relative to normal. Under normal lighting, visual cues from the lines on the walking surface induced a significant improvement in gait velocity and stride length in Parkinson's disease patients. With stroboscopic illumination and without lines, both groups reduced their stride length and velocity but the changes were significant only in the Parkinson's disease group, indicating greater dependence on dynamic visual information. When stroboscopic light was used with stripes on the floor, the improvement in gait due to the stripes was suppressed in parkinsonian patients. These results demonstrate that the perceived motion of stripes, induced by the patient's walking, is essential to improve the gait parameters and thus favour the hypothesis of a specific visual-motor pathway which is particularly responsive to rapidly moving targets. Previous studies have proposed a cerebellar circuit, allowing the visual stimuli to by-pass the damaged basal ganglia.  (+info)

Object location learning and non-spatial working memory of patients with Parkinson's disease may be preserved in "real life" situations. (4/6239)

The presence of a spatial memory deficit in Parkinson's disease (PD) is still a matter of discussion. Nineteen PD patients and 16 controls were given two spatial tests and a non-spatial task. First, the subject was led into a room containing 4 objects and had 10 s to memorize their location. After being led outside, the subject had to place icons representing the objects on a map of the room. Differences between the real and estimated locations were evaluated. Afterwards, the subject had to choose a map showing the correct arrangement of objects from 4 alternatives. Locations of some objects were changed before the second test. The subject had 10 s to detect these changes. One point was given for each change or its absence detected. In the non-spatial working memory task, 8 cards of different shapes were used. The subject had to select a different card each time while the cards were shuffled between choices. Errors consisted of selecting previously chosen cards. The means of the above measures for both groups were compared. Absence of any significant differences suggests that PD patients perform well in "real life" memory tests in contrast to similar computerized tests.  (+info)

Impairment in preattentive visual processing in patients with Parkinson's disease. (5/6239)

We explored the possibility of whether preattentive visual processing is impaired in Parkinson's disease. With this aim, visual discrimination thresholds for orientation texture stimuli were determined in two separate measurement sessions in 16 patients with idiopathic Parkinson's disease. The results were compared with those of 16 control subjects age-matched and 16 young healthy volunteers. Discrimination thresholds were measured in a four-alternative spatial forced-choice paradigm, in which subjects judged the location of a target embedded in a background of distractors. Four different stimulus configurations were employed: (i) a group of vertical targets among horizontal distractors ('vertical line targets'); (ii) targets with varying levels of orientation difference on a background of spatially filtered vertically oriented noise ('Gaussian filtered noise'); (iii) one 'L' among 43 '+' signs ('texton'), all of which assess preattentive visual processing; and (iv) control condition, of one 'L' among 43 'T' distractors ('non-texton' search target), which reflects attentive visual processing. In two of the preattentive tasks (filtered noise and texton), patients with Parkinson's disease required significantly greater orientation differences and longer stimulus durations, respectively. In contrast, their performance in the vertical line target and non-texton search target was comparable to that of the matched control subjects. These differences were more pronounced in the first compared with the second session. Duration of illness and age within the patient group correlated significantly with test performance. In all conditions tested, the young control subjects performed significantly better than the more elderly control group, further indicating an effect of age on this form of visual processing. The results suggest that, in addition to the well documented impairment in retinal processing, idiopathic Parkinson's disease is associated with a deficit in preattentive cortical visual processing.  (+info)

The effects of posteroventral pallidotomy on the preparation and execution of voluntary hand and arm movements in Parkinson's disease. (6/6239)

We studied the effect of posteroventral pallidotomy on movement preparation and execution in 27 parkinsonian patients using various motor tasks. Patients were evaluated after overnight withdrawal of medication before and 3 months after unilateral pallidotomy. Surgery had no effect on initiation time in unwarned simple and choice reaction time tasks, whereas movement time measured during the same tasks was improved for the contralesional hand. Movement times also improved for isometric and isotonic ballistic movements. In contrast, repetitive, distal and fine movements measured in finger-tapping and pegboard tasks were not improved after pallidotomy. Preparatory processes were investigated using both behavioural and electrophysiological measures. A precued choice reaction time task suggested an enhancement of motor preparation for the contralesional hand. Similarly, movement-related cortical potentials showed an increase in the slope of the late component (NS2) when the patients performed joystick movements with the contralesional hand. However, no significant change was found for the early component (NS1) or when the patient moved the ipsilesional hand. The amplitude of the long-latency stretch reflex of the contralesional hand decreased after surgery. In summary, the data suggest that pallidotomy improved mainly the later stages of movement preparation and the execution of proximal movements with the contralesional limb. These results provide detailed quantitative data on the impact of posteroventral pallidotomy on previously described measures of upper limb akinesia in Parkinson's disease.  (+info)

Low-dose clozapine for the treatment of drug-induced psychosis in Parkinson's disease. The Parkinson Study Group. (7/6239)

BACKGROUND: Drug-induced psychosis is a difficult problem to manage in patients with Parkinson's disease. Multiple open-label studies have reported that treatment with clozapine at low doses ameliorates psychosis without worsening parkinsonism. METHODS: We conducted a randomized, double-blind, placebo-controlled trial of low doses of clozapine (6.25 to 50 mg per day) in 60 patients at six sites over a period of 14 months. The patients (mean age, 72 years) had idiopathic Parkinson's disease and drug-induced psychosis of at least four weeks' duration. All the patients continued to receive fixed doses of antiparkinsonian drugs during the four weeks of the trial. Blood counts were monitored weekly in all the patients. RESULTS: The mean dose of clozapine was 24.7 mg per day. The patients in the clozapine group had significantly more improvement than those in the placebo group in all three of the measures used to determine the severity of psychosis. The mean (+/-SE) scores on the Clinical Global Impression Scale improved by 1.6+/-0.3 points for the patients receiving clozapine, as compared with 0.5+/-0.2 point for those receiving placebo (P<0.001). The score on the Brief Psychiatric Rating Scale improved by 9.3+/-1.5 points for the patients receiving clozapine, as compared with 2.6+/-1.3 points for those receiving placebo (P=0.002). The score on the Scale for the Assessment of Positive Symptoms improved by 11.8+/-2.0 points for the patients receiving clozapine, as compared with 3.8+/-1.9 points for those receiving placebo (P=0.01). Seven patients treated with clozapine had an improvement of at least three on the seven-point Clinical Global Impression Scale, as compared with only one patient given placebo. Clozapine treatment improved tremor and had no deleterious effect on the severity of parkinsonism. In one patient, clozapine was discontinued because of leukopenia. CONCLUSIONS: Clozapine, at daily doses of 50 mg or less, is safe and significantly improves drug-induced psychosis without worsening parkinsonism.  (+info)

A wide variety of mutations in the parkin gene are responsible for autosomal recessive parkinsonism in Europe. French Parkinson's Disease Genetics Study Group and the European Consortium on Genetic Susceptibility in Parkinson's Disease. (8/6239)

Autosomal recessive juvenile parkinsonism (AR-JP, PARK2; OMIM 602544), one of the monogenic forms of Parkinson's disease (PD), was initially described in Japan. It is characterized by early onset (before age 40), marked response to levodopa treatment and levodopa-induced dyskinesias. The gene responsible for AR-JP was recently identified and designated parkin. We have analysed the 12 coding exons of the parkin gene in 35 mostly European families with early onset autosomal recessive parkinsonism. In one family, a homozygous deletion of exon 4 could be demonstrated. By direct sequencing of the exons in the index patients of the remaining 34 families, eight previously undescribed point mutations (homozygous or heterozygous) were detected in eight families that included 20 patients. The mutations segregated with the disease in the families and were not detected on 110-166 control chromosomes. Four mutations caused truncation of the parkin protein. Three were frameshifts (202-203delAG, 255delA and 321-322insGT) and one a nonsense mutation (Trp453Stop). The other four were missense mutations (Lys161Asn, Arg256Cys, Arg275Trp and Thr415Asn) that probably affect amino acids that are important for the function of the parkin protein, since they result in the same phenotype as truncating mutations or homozygous exon deletions. Mean age at onset was 38 +/- 12 years, but onset up to age 58 was observed. Mutations in the parkin gene are therefore not invariably associated with early onset parkinsonism. In many patients, the phenotype is indistinguishable from that of idiopathic PD. This study has shown that a wide variety of different mutations in the parkin gene are a common cause of autosomal recessive parkinsonism in Europe and that different types of point mutations seem to be more frequently responsible for the disease phenotype than are deletions.  (+info)

What is early onset Parkinsons disease, and how is it different? Learn how Parkinsons can affect younger individuals how their experience may differ.
The majority of patients with advanced Parkinsons disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinsons disease; the proportion of Parkinsons patients with advanced Parkinsons disease, the referral process, and the clinical features used to characterize advanced Parkinsons disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinsons patients identified as advanced patients according to physicians judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinsons disease status was assessed with Unified Parkinsons Disease Rating Scale (UPDRS) parts II, III, IV, and V ...
Parkinson disease (PD) is a progressive neurodegenerative disease that affects more than 1,000,000 Americans. Currently there is no proven therapy to reduce the rate of progression of PD. In a previous phase II clinical trial, investigators demonstrated that Coenzyme Q10 (CoQ) at dosages of 300, 600, and 1200 mg/day was safe and well-tolerated in individuals with early, untreated PD. The findings also suggested that CoQ may slow the progressive impairment of PD as measured by the Unified Parkinson Disease Rating Scale (UPDRS).. In this study, researchers will conduct a randomized, placebo-controlled, phase III trial of CoQ to confirm and extend the results of the earlier phase II study. The primary objective of this trial is to compare the effect of two dosages of CoQ (1200 and 2400 mg/day) and placebo on the total UPDRS score in people with early PD. The study also will evaluate independent function, cognition, and quality of life. Plasma CoQ levels will be measured at months 1, 8 and 16 and ...

The G2019S mutation in the LRRK2 gene is reportedly a common cause of familial Parkinsons disease (PD) and may also have a significant role in nonfamilial PD. The objective of this study was to assess mutation carrier frequency in PD patients from movement disorder clinics in the United States, stratified by family history, age at onset, and geography; to determine carrier frequency in a large and well-characterized control population; to examine segregation of mutation in families of patients; and to correlate genotype with clinical phenotype. One thousand four hundred twenty-five unrelated PD patients from movement disorder clinics in Oregon, Washington, and New York and 1,647 unrelated controls were studied. The G2019S mutation was detected using a TaqMan assay and verified by sequencing. Eighteen of 1,425 patients and one of 1,647 controls had the mutation. Carrier frequency (± 2SE) in patients was 0.013 ± 0.006 overall, 0.030 ± 0.019 in familial PD, 0.007 ± 0.005 in nonfamilial PD, ...

A National Institutes of Health-funded study shows that cells from patients with different types of Parkinson disease have unique drug responses, a finding that suggests that personalized medicine for the disease is possible.. For this study, researchers collected skin cells from patients with genetically inherited forms of Parkinson disease and reprogrammed those cells into neurons. They found that neurons derived from people with distinct types of the disease showed common signs of distress and vulnerability-in particular, abnormalities in the cellular energy factories known as mitochondria. At the same time, the cells responses to different treatments depended on the type of Parkinson disease that each patient had.. Most cases of Parkinson disease are sporadic, meaning that the cause is unknown. However, genetics plays a strong role. There are 17 regions of the genome with common variations that affect the risk of developing Parkinson disease. Researchers also have identified 9 genes that, ...
To accompany the newly developed Movement Disorder Society revision of the Unified Parkinsons Disease Rating Scale (MDS-UPDRS), we developed a teaching program. The DVD-based program covers the four parts of the scale with visual and verbal instructions for uniform application. For the motor section (Part III), all items except rigidity are shown with an example of each rating option (0-4) as agreed upon by a panel of experts. The rate of agreement for the selected samples was always significant, with Kendalls coefficient of concordance W ranging between 0.99 and 0.72. The teaching program also provides a full patient examination with rating answers provided and four full MDS-UPDRS cases for a Certificate Program exercise of Part III. This training program is in English, but as non-English official translations of the MDS-UPDRS are developed, the program can be potentially modified into different languages. © 2010 Movement Disorder Society ...
Parkinson disease (PD) is a common neurodegenerative movement disorder that increases in prevalence with age. It is characterized clinically by resting tremor, rigidity, bradykinesia, and failing balance, and is due to the gradual loss of the dopaminergic neurons in the substantia nigra of the midbrain. Different factors including environmental (1-methyl-4- phenyl-1,2,3,6-tetrahydropyridine (MPTP), 6- hydroxydopamine (6-OHDA), etc.) and genetic (PINK1, DJ1 and LRRK2) have been found to cause the loss of the dopaminergic neurons in the substantia nigra. In addition, deficiency of respiratory chain complexes (complex I, II and IV) and increased levels of mtDNA deletions have been identified in PD patients. All of these factors, from the environmental to the genetic and the biochemical converge on one site, namely the mitochondrion: MPTP poisons complex I of the respiratory chain, PINK1, DJ1 and LRRK2 have all been linked to mitochondrial and lastly, mutations in the catalytic subunit of the ...

Medical treatment of idiopathic Parkinson disease motor symptoms requires dopaminergic drugs, with long term disabling side effects. (fluctuations, dyskinesia, ON/OFF phenomena). Use of nicotine in Parkinsons disease has been suggested by the lowest prevalence of smokers among Parkinsonian patients. However, controlled studies provided conflicting results. One of our patients showed a substantial decrease of his parkinsonian symptoms under transdermal nicotine-therapy. Currently, this patient has been treated since 8 years with an excellent safety, especially on cardiovascular level. Otherwise, the investigators performed an open pilot safety and feasibility study in 6 patients, which demonstrated the possibility of a controlled study. In this study, all patients received daily doses during several months until 105 mg/day and could, in parallel, decrease their L-Dopa and agonists doses, improving their motor scores.. The investigators now propose a phase II, controlled, single blind and ...

Five genes have been identified that contribute to Mendelian forms of Parkinson disease (PD); however, mutations have been found in fewer than 5% of patients, suggesting that additional genes contribute to disease risk. Unlike previous studies that focused primarily on sporadic PD, we have performed the first genomewide association study (GWAS) in familial PD. Genotyping was performed with the Illumina HumanCNV370Duo array in 857 familial PD cases and 867 controls. A logistic model was employed to test for association under additive and recessive modes of inheritance after adjusting for gender and age. No result met genomewide significance based on a conservative Bonferroni correction. The strongest association result was with SNPs in the GAK/DGKQ region on chromosome 4 (additive model: p = 3.4 × 10-6; OR = 1.69). Consistent evidence of association was also observed to the chromosomal regions containing SNCA (additive model: p = 5.5 × 10-5; OR = 1.35) and MAPT (recessive model: p = 2.0 × ...
Background: The PARK2 gene at 6q26 encodes parkin, whose inactivation is implicated in an early-onset autosomal recessive form of Parkinson disease (PD). Objective: To evaluate the influence of heterozygosity for parkin mutation on onset age in a sample of families with at least 2 PD-affected members. Design: Clinical and genetic study. Setting: Twenty collaborative clinical sites. Patients: Patients with familial PD collected in the GenePD study. Studied families were selected for (1) affected sibling pairs sharing 2 alleles identical by state at PARK2 (D6S305) or (2) 1 or more family members with onset age younger than 54 years, regardless of D6S305 status. At least 1 member from each of 183 families underwent comprehensive screening for deletion/insertion variants and point mutations in PARK2. Main Outcome Measures: Mutations in the parkin gene were screened by means of single-stranded conformation polymorphism and sequencing in all 12 coding exons and flanking intronic sequences for point ...

Multiple missense mutations in Leucine-rich repeat kinase 2 (LRRK2) are associated with familial forms of late onset Parkinsons disease (PD), the most common age-related movement disorder. The dysfunction of dopamine transmission contributes to PD-related motor symptoms. Interestingly, LRRK2 is more abundant in the dopaminoceptive striatal spiny projection neurons (SPNs) compared to the dopamine-producing nigrostriatal dopaminergic neurons. Aging is the most important risk factor for PD and other neurodegenerative diseases. However, whether LRRK2 modulates the aging of SPNs remains to be determined. We conducted RNA-sequencing (RNA-seq) analyses of striatal tissues isolated from Lrrk2 knockout (Lrrk2−/−) and control (Lrrk2+/+) mice at 2 and 12 months of age. We examined SPN nuclear DNA damage and epigenetic modifications; SPN nuclear, cell body and dendritic morphology; and the locomotion and motor skill learning of Lrrk2+/+ and Lrrk2−/− mice from 2 to 24 months of age. Considering the strength
Parkinson s disease occurs both sporadically and as a result of inheritance of single gene mutations. One of the most common neurodegenerative disorders, it is associated with the progressive and selective loss of a specific population of neurons in the brain, the dopaminergic neurons of the substantia nigra pars compacta . Exposure to several common environmental toxins, thought to injure neurons through oxidative damage, has been shown to be associated with sporadic forms of Parkinson s disease. During the past decade, researchers have also made remarkable progress in identifying genes responsible for inherited forms of Parkinson s disease, with the expectation that understanding the function of these genes will elucidate mechanisms behind sporadic Parkinson s disease. Past work had shown that one form of familial Parkinson s disease results from a loss of function of a gene called DJ-1 ...
The effectiveness of ventroposterolateral pallidotomy in the treatment of akinesia and rigidity is not a new discovery and agrees with recent investigations into the pathogenesis of Parkinsons disease, which highlight the role played by the unbridled activity of the subthalamic nucleus (STN) and the consequent overactivity of the globus pallidus internalis (GPi). Because high-frequency stimulation can reversibly incapacitate a nerve structure, we applied stimulation to the same target.. Seven patients suffering from severe Parkinsons disease (Stages III-V on the Hoehn and Yahr scale) and, particularly, bradykinesia, rigidity, and levodopa-induced dyskinesias underwent unilateral electrode implantation in the posteroventral GPi. Follow-up evaluation using the regular Unified Parkinsons Disease Rating Scale has been conducted for 1 year in all seven patients, 2 years in five of them, and 3 years in one. In all cases high-frequency stimulation has alleviated akinesia and rigidity and has ...

Genetic classification of Parkinsons disease (PD) subtypes may become the preferred diagnostic tool for neurologists. Herein we compare clinical features from a large cohort of patients with familial PD of unknown aetiology or attributable to distinct genetic forms. Comprehensive neurological examinations were performed in 231 familial PD patients from Tunisia. Analysis was previously performed to screen for mutations in leucine rich repeat kinase 2 (LRRK2), PTEN induced kinase 1 (PINK1) and parkin (PRKN). Clinical features were compared between patients with genetically undefined PD (n=107) and those with LRRK2 (n=73) and PINK1 (n=42) mutations using regression analyses adjusted for gender, age of onset and disease duration. PRKN cases (n=9) were too few for meaningful statistical analysis. In comparison with genetically undefined patients, LRRK2 mutation carriers had more severe motor symptoms (median Unified Parkinsons Disease Rating Scale scores ∼1.6 times higher, p,0.001), a higher rate ...

Parkinsonism is a progressive motor disease that affects 1.5 million Americans and is the second most common neurodegenerative disease after Alzheimers. Typical neuropathological features of Parkinsons disease (PD) include degeneration of dopaminergic neurons located in the pars compacta of the substantia nigra that project to the striatum (nigro-striatal pathway) and depositions of cytoplasmic fibrillary inclusions (Lewy bodies) which contain ubiquitin and α-synuclein. The cardinal motor signs of PD are tremors, rigidity, slow movement (bradykinesia), poor balance, and difficulty in walking (Parkinsonian gait). In addition to motor symptoms, non-motor symptoms that include autonomic and psychiatric as well as cognitive impairments are pressing issues that need to be addressed. Several different mechanisms play an important role in generation of Lewy bodies; endoplasmic reticulum (ER) stress induced unfolded proteins, neuroinflammation and eventual loss of dopaminergic neurons in the substantia nigra
Slovenščina (Slovenian). Parkinsons disease is traditionally regarded as a movement disorder caused by the loss of dopaminergic neurons in the nigrostriatal system. However, we are becoming more and more aware that pathology of this disease is much wider than initially thought and that degeneration may involve many areas in both central and peripheral nervous systems. This is reflected in a wide spectrum of non-motor symptoms that involve sleep, psychiatric, cognitive, autonomic and sensory disorders. Non-motor symptoms occur in more than 98% of the patients with Parkinsons disease. They can appear at anytime in the course of disease and are often present in the preclinical phase (pre-motor symptoms). The pre-motor symptoms can predate the onset of Parkinsons disease and they could be used as biomarkers for identifying persons at risk for development of Parkinsons disease. Early detection of Parkinsons disease will be of considerable value when neuroprotective therapy becomes available. ...
IgG-class autoantibodies to N-Methyl-D-Aspartate (NMDA)-type glutamate receptors define a novel entity of autoimmune encephalitis. Studies examining the prevalence of NMDA IgA/IgM antibodies in patients with Parkinson disease with/without dementia produced conflicting results. We measured NMDA antibodies in a large, well phenotyped sample of Parkinson patients without and with cognitive impairment (n = 296) and controls (n = 295) free of neuropsychiatric disease. Detailed phenotyping and large numbers allowed statistically meaningful correlation of antibody status with diagnostic subgroups as well as quantitative indicators of disease severity and cognitive impairment. NMDA antibodies were analysed in the serum of patients and controls using well established validated assays. We used anti-NMDA antibody positivity as the main independent variable and correlated it with disease status and phenotypic characteristics. The frequency of NMDA IgA/IgM antibodies was lower in Parkinson patients (13%) than in

Parkinsons disease (PD) is a common neurodegenerative disorder that is characterized by the loss of dopaminergic neurons in the substantia nigra and the presence of cytoplasmic protein inclusions known as Lewy bodies. The majority of PD cases are sporadic; however, the identification of a number of genes responsible for rare familial forms of PD has provided important insights into the underlying mechanisms of the disease. These genes, encoding α-synuclein, parkin, UCH-L1, and DJ-1, have implicated protein misfolding, impairment of the ubiquitin-proteasome system, and oxidative stress in the pathogenesis of the disease (1, 2).. We previously mapped PARK6, a locus linked to autosomal recessive, early-onset PD, to a 12.5-centimorgan (cM) region on chromosome 1p35-p36 by autozygosity mapping in a large consanguineous family from Sicily (3). Subsequent identification of two additional consanguineous families [one from central Italy (family IT-GR) (4) and one from Spain] provided additional ...
Mutations in leucine-rich do it again kinase 2 (LRRK2) comprise the most common cause of familial Parkinsons disease (PD), and sequence variants modify risk for sporadic PD. elucidate the mechanism underlying the increased MT association of select pathogenic LRRK2 mutants or of pharmacologically kinase-inhibited LRRK2, with implications for downstream MT-mediated transport events. Introduction Parkinsons disease (PD) is usually a common neurodegenerative disease with incompletely comprehended etiology, affecting around 1C2% of the elderly (1). Mutations in the leucine-rich repeat kinase 2 (LRRK2) gene cause PD inherited in an autosomal-dominant fashion (2,3). Additionally, numerous variants have been recognized which either positively or negatively correlate with PD risk (4C9), highlighting the general importance of LRRK2 for disease pathogenesis. The LRRK2 protein contains numerous domains implicated in proteinCprotein interactions, as well as a central region comprised of a Ras-of-complex ...

BACKGROUND: Agitation is a common, challenging symptom affecting large numbers of people with dementia and impacting on quality of life (QoL). There is an urgent need for evidence-based, cost-effective psychosocial interventions to improve these outcomes, particularly in the absence of safe, effective pharmacological therapies. This study aimed to evaluate the efficacy of a person-centred care and psychosocial intervention incorporating an antipsychotic review, WHELD, on QoL, agitation, and antipsychotic use in people with dementia living in nursing homes, and to determine its cost. METHODS AND FINDINGS: This was a randomised controlled cluster trial conducted between 1 January 2013 and 30 September 2015 that compared the WHELD intervention with treatment as usual (TAU) in people with dementia living in 69 UK nursing homes, using an intention to treat analysis. All nursing homes allocated to the intervention received staff training in person-centred care and social interaction and education ...
A multiethnic series of patients with early-onset Parkinsons disease (EOP) was studied to assess the frequency and nature of parkin/PARK2 gene mutations and to investigate phenotype-genotype relationships. Forty-six EOP probands with an onset age of | 45 years, and 14 affected relatives were ascertained from Italy, Brazil, Cuba, and Turkey. The genetic screening included direct sequencing and exon dosage using a new, cost-effective, real-time polymerase chain reaction method. Mutations were found in 33% of the indexes overall, and in 53% of those with family history compatible with autosomal recessive inheritance. Fifteen parkin alterations (10 exon deletions and five point mutations) were identified, including four novel mutations: Arg402Cys, Cys418Arg, IVS11-3C | G, and exon 8-9-10 deletion. Homozygous mutations, two heterozygous mutations, and a single heterozygous mutation were found in 8, 6, and 1 patient, respectively. Heterozygous exon deletions represented 28% of the mutant alleles. The
Pain management in patients with Parkinson's disease: challenges and solutions Orjan Skogar,1,2 Johan Lokk2 1Academy for Health and Care (FUTURUM), Region Jönköping County, Jönköping, 2Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Huddinge, Stockholm, Sweden Abstract: This review focuses on the diagnosis and management of Parkinson-related pain which is one of the more frequently reported nonmotor symptoms in Parkinson’s disease (PD), which is the second most common neurodegenerative disease after Alzheimer’s disease. Pain is ranked high by patients as a troublesome symptom in all stages of the disease. In early-stage PD, pain is rated as the most bothersome symptom. Knowledge of the correct diagnosis of pain origin and possible methods of treatments for pain relief in PD is of great importance. The symptoms have a great negative impact on health-related quality of life. Separating PD-related pain from pain of other origins is an
Parkinson-like symptoms can also occur as a result of head injuries, carbon monoxide poisoning or poisoning by pharmaceutical or other drugs. Certain diuretics (reserpine), antipsychotics (chlorpromazine), and heart drugs (verapamil) have all been implicated in causing or worsening Parkinsons disease symptoms as has the designer drug MPTP (methylphenyl-tetrahydropyridine). In some cases, drug-induced Parkinsons disease may be halted or reversed if the drug is promptly withdrawn. Naproxen and other NSAIDs (non-steroidal anti-inflammatory drugs) may also exacerbate Parkinsons disease(1,2,8-10).. Recent research carried out in Iceland, which has a very high incidence of Parkinsons disease, has shown that children born during or after a whooping cough (pertussis) epidemic are particularly vulnerable to Parkinsons disease in later life(11). This finding supports the idea that Parkinsons disease may develop later in life as a result of a neurotoxic event that occurred at an early ...

Parkinsons disease is a chronic, progressive neurodegenerative movement disorder. Tremors, rigidity, slow movement (bradykinesia), poor balance, and difficulty walking (called parkinsonian gait) are characteristic primary symptoms of Parkinsons disease.
Parkinsons Disease (PD) is a chronic, neurodegenerative movement disorder that affects the lives of more than 1 million Americans. PD slowly worsens over time, increasingly robbing patients of coordinated movement and inflicting a number non-motor symptoms ranging from cognitive impairment to gastrointestinal issues. Approximately 90 percent of PD cases occur spontaneously, while 10 percent of cases are familial. PD mainly affects the elderly, however the cause of PD is unknown. There are currently no treatments that can slow or stop the relentless progression of the disease. ...

BACKGROUND: Pedunculopontine nucleus (PPN) stimulation is a novel therapy for Parkinson disease. However, controversies remain regarding the clinical application of this new therapy, including patient selection, electrode positioning, and how best to assess outcomes. OBJECTIVE: To clarify the clinical application of PPN stimulation in Parkinson disease. METHODS: Five consecutive patients with Parkinson disease complicated by severe gait freezing, postural instability, and frequent falls (all persisting even while the patient was on medication) received bilateral stimulation of the mid-lower PPN without costimulation of other brain targets. Outcomes were assessed prospectively over 2 years with gait-specific questionnaires and the Unified Parkinson Disease Rating Scale (part III). RESULTS: The primary outcome, the Gait and Falls Questionnaire score, improved significantly with stimulation. Benefits were maintained over 2 years. Unified Parkinson Disease Rating Scale (part III) items assessing gait and
Deep brain stimulation (DBS) is associated with significant improvement of motor complications in patients with severe Parkinsons disease after some 6-12 months of treatment.. Long-term results in a large number of patients have been reported only from a single study centre. We report 69 Parkinsons disease patients treated with bilateral DBS of the subthalamic nucleus (STN, n = 49) or globus pallidus internus (GPi, n = 20) included in a multicentre study.. Patients were assessed preoperatively and at 1 year and 3-4 years after surgery. The primary outcome measure was the change in the off medication score of the Unified Parkinsons Disease Rating Scale motor part (UPDRS-III) at 3-4 years. Stimulation of the STN or GPi induced a significant improvement (50 and 39%; P , 0.0001) of the off medication UPDRS-III score at 3-4 years with respect to baseline. Stimulation improved cardinal features and activities of daily living (ADL) (P , 0.0001 and P , 0.02 for STN and GPi, respectively) and ...

Apart from the typical motor symptoms, Parkinsons disease is characterized by a wide range of different non-motor symptoms, which are highly prevalent in all stages of the disease and have an incisive influence on quality of life. Moreover, their treatment continues to be challenging. In this review, we critically summarize the evidence for the impact of dopaminergic therapies on non-motor symptoms in Parkinsons disease. We performed a PubMed search to identify relevant clinical studies that investigated the response of non-motor symptoms to dopaminergic therapy. In the domain of neuropsychiatric disturbances, there is increasing evidence that dopamine agonists can ameliorate depression or anxiety. Other neuropsychiatric symptoms such as psychosis or impulse control disorders can also be worsened or even be induced by dopaminergic agents. For the treatment of sleep disturbances, it is essential to identify different subtypes of sleep pathologies. While there is for example profound evidence ...
Idiopathic Parkinsons disease is a common neurodegenerative disease with characteristic neuropathology and lifetime incidence approaching 2%.1 The neurodegenerative changes, associated with Lewy bodies in the surviving neurons, are centred on the substantia nigra, locus ceruleus, nucleus basalis, cranial nerve motor nuclei, hypothalamus, cerebral cortex, and autonomic nervous system.2 The pathological processes underlying this neurodegeneration are unknown, but there is increasing evidence for the role of genetic susceptibility in Parkinsons disease.3 Families with autosomal dominant parkinsonism have been described,4 although the clinical features of many of these are atypical for Parkinsons disease. Polymeropouloset al studied a large Italian-American pedigree and linked the Parkinsons disease-1 locus to chromosome 4q21-23.5 Further study led to the identification of a point mutation (G209A) within the α-synuclein gene on chromosome 4q21-22 in this kindred and three unrelated families of ...

INTRODUCTION: Changes in personality have been described in Parkinsons disease (PD), with suggestion that those with established disease tend to be risk averse with a disinclination for addictive behaviour. However, little is known about the earliest and prodromal stages. Personality and its relationship with addictive behaviours can help answer important questions about the mechanisms underlying PD and addiction. METHODS: 941 population-ascertained PD subjects within 3.5 years of diagnosis, 128 patients with rapid eye movement sleep behaviour disorder (RBD) and 292 control subjects were fully characterised for motor symptoms, non-motor symptoms and across the following 5 personality domains: 1) neuroticism 2) extraversion 3) conscientiousness 4) agreeableness 5) openness using the Big Five Inventory. RESULTS: Patients with early PD were more neurotic (p | 0.001), less extraverted (p | 0.001) and less open than controls (p | 0.001). RBD subjects showed the same pattern of being more neurotic (p | 0.001

STUDY OBJECTIVES: To explore rapid eye movement density (RD) in patients with idiopathic Parkinson disease (IPD) and to investigate its usefulness as surrogate marker of excessive daytime sleepiness, a frequent complaint in IPD patients. METHODS: Retrospective polysomnography study on 81 subjects without dementia: 29 patients with early stage IPD (disease duration ,/= 3 y), 21 patients with middle- stage IPD (disease duration , 3 and , 8 y) and 31 healthy controls (HC). Rapid eye movement (REM) sleep was defined as any REM episode with , 3 min of continuous REM sleep. RD was defined as number of ocular movements per minute of REM sleep. Patients with early stage IPD and HC fulfilled the PD-specific sleepiness questionnaires Parkinsons Disease Sleep Scale (PDSS) and the Nonmotor Symptoms Questionnaire for Parkinsons disease (NMSQuest). RESULTS: RD was lower in patients with IPD than in HC. The difference was most significant between patients with middle stage IPD and HC (P = 0.001), and most ...
Printer Friendly Version. Parkinsons Disease - revised last 11/15/17. Parkinsons disease was first described in 1817 by a London physician, James Parkinson. He described the hallmarks of the condition which is tremor, rigidity, bradykinesia, and gait dysfunction. The disease is due to degeneration of neurons in the substantia niagra and in the 1960s it was discovered that dopamine was depleted in the disease. Therefore, levodopa, a precursor to dopamine was developed as medication to improve the symptoms. The Hollywood film, Awakenings, starring Robin Williams, depicts the early use of levodopa to treat patients with a rare form of parkinsons disease related to an epidemic of encephalitis. Parkinsons disease is one of the most common movement disorders. The average age of onset is about 60 years old and age is the one clear risk factor. Five to ten percent of patients have early onset Parkinsons disease which is onset before age 50. A subset of patients have Parkinsons disease due to some ...

N2 - Gene-based therapies for neurological diseases continue to develop briskly. As disease mechanisms are elucidated, flexible gene delivery platforms incorporating transcriptional regulatory elements, therapeutic genes and targeted delivery are required for the safety and efficacy of these approaches. Adenovirus serotype 5 (Ad5)-based vectors can carry large genetic payloads to provide this flexibility, but do not transduce neuronal cells efficiently. To address this, we have developed a tropism-modified Ad5 vector with neuron-selective targeting properties for evaluation in models of Parkinson disease therapy. A panel of tropism-modified Ad5 vectors was screened for enhanced ...
Parkinsons disease (PD) is a progressive neurodegenerative movement disorder that results primarily from the death of dopaminergic (DA) neurons in the substantia nigra pars compacta (SNc). Mutations in alpha-synuclein, UCHL1 (a ubiquitin carboxy-terminal hydrolase L1), parkin, DJ1 (a parkin-associated protein involved with oxidative stress), and PINK1 (a putative serine threonine kinase) are known to cause early-onset PD. Mutations or altered expression of these proteins contributes to the damage and subsequent loss of DA neurons through common mechanisms that result in proteasome dysfunction, mitochondrial impairment, and oxidative stress. The demise of DA neurons located in the SNc leads to a drop in the dopaminergic input to the striatum. This results in a reduced activation of the direct pathway and in a disinhibition of the indirect pathway, which is associated with the elevation of adenosine A2A receptor transmission. Such unbalanced activity of the striatal output pathway is at the basis ...

Alpha-synuclein (SNCA) genetic variability has been implicated in many susceptibility studies of idiopathic Parkinson s disease (PD), Dementia with Lewy bodies (DLB, typically described as Diffuse Lewy body Disease (DLBD) post-mortem) and to a lesser extent multiple system atrophy (MSA). However, which precise variant within the region contributes to the clinical (movement and cognitive) or pathologic phenotypes is unclear. In this study we proposed to sequence the entire SNCA genomic locus (and171 other genes implicated in dopamine metabolism, parkinsonism, dementia and neurodegeneration) to identify specific SNCA biomarkers. Towards this end complete resequencing and/or genotyping has been accomplished for: a) de novo PD (the entire Parkinson s Progressive Markers Initiative series); b) four PD-MCI cohorts (patients with ,5 progression with detailed longitudinal evaluation beyond another 3-8 years and data on PD‐MCI and PDD to MCI (level II) criteria), and; c) autopsy-confirmed Lewy body ...

In their article Deep brain stimulation in early-stage Parkinson disease: Five-year outcomes,1 Dr. Hacker and colleagues compared 2 groups of people with Parkinson disease (PD): those who only took medication for their PD and those who combined medications with deep brain stimulation (DBS). Other studies have taken a similar approach, but this study was different because it looked at people who had early PD. Most past studies have focused only on people with moderate or advanced PD. In addition, this study looked at outcomes after 5 years. Most studies are shorter, and do not look at how people do over a long period of time. ...

Exposure to manganese (Mn) is associated with neurobehavioral effects. There is disagreement on whether commonly occurring exposures in welding, ferroalloy, and other industrial processes produce neurologically significant neurobehavioral changes representing parkinsonism. A review of methodological issues in the human epidemiological literature on Mn identified: (1) studies focused on idiopathic Parkinson disease without considering manganism, a parkinsonian syndrome; (2) studies with healthy worker effect bias; (3) studies with problematic statistical modeling; and (4) studies arising from case series derived from litigation. Investigations with adequate study design and exposure assessment revealed consistent neurobehavioral effects and attributable subclinical and clinical signs and symptoms of impairment. Twenty-eight studies show an exposure-response relationship between Mn and neurobehavioral effects, including 11 with continuous exposure metrics and six with three or four levels of ...
Parkinsons disease (PD) is characterized by a progressive loss of midbrain dopamine neurons and the presence of cytoplasmic inclusions called Lewy bodies. Mutations in several genes including alpha-synuclein and parkin have been linked to familial PD. The loss of parkins E3-ligase activity leads to dopaminergic neuronal degeneration in early-onset autosomal recessive juvenile parkinsonism, suggesting a key role of parkin for dopamine neuron survival. To evaluate the potential neuroprotective role of parkin in the pathogenesis of PD, we tested whether overexpression of wild-type rat parkin could protect against the toxicity of mutated human A30P alpha-synuclein in a rat lentiviral model of PD. Animals overexpressing parkin showed significant reductions in alpha-synuclein-induced neuropathology, including preservation of tyrosine hydroxylase-positive cell bodies in the substantia nigra and sparing of tyrosine hydroxylase-positive nerve terminals in the striatum. The parkin-mediated neuroprotection was
The good news is preclinical research shows this stress can be controlled with a drug already approved for human use. By preventing calcium entry, the drug isradipine reduced the mitochondrial stress in dopamine-releasing neurons to the levels seen in neurons not affected by the disease. Northwestern Medicine scientists currently are conducting a clinical trial to find out if isradipine can be used safely and is tolerated by patients with Parkinsons. Isradipine is already approved by the Food and Drug Administration for treatment of high blood pressure. Parkinsons disease is the second most common neurodegenerative disease in the United States, second only to Alzheimers disease. The average age of diagnosis is near 60. More than 1 million Americans currently have Parkinsons disease, and this number is rising as the population ages. The symptoms of Parkinsons disease include rigidity, slowness of movement and tremors. No treatment currently is known to prevent or slow the progression of ...
Background: Non‐motor symptoms (NMS) in Parkinsons disease (PD) differ from those in essential tremor (ET), even before a definitive diagnosis is made. It is not clear whether patients knowledge of the diagnosis and treatment influence their subsequent reporting of NMS. Methods: 1 year after a clinical and instrumental diagnosis, we compared the motor impairment (Movement Disorders Society (MDS)‐Unified Parkinsons Disease Rating Scale‐III) and non‐motor symptoms (NMSQuest) in PD (n = 31) and ET (n = 21) patients. Results: PD patients reported more NMS than did the ET patients (p = 0.002). When compared to their baseline report, at follow‐up, PD patients reported less nocturia (p = 0.02), sadness (p = 0.01), insomnia (p = 0.02), and restless legs (p = 0.04) and more nausea (p = 0.024), unexplained pain (p = 0.03), weight change (p = 0.009), and daytime sleepiness (p = 0.03). When compared to their baseline report, ET patients reported less loss of interest (p = 0.03), anxiety (p = 0.006),

The major benefit of DBS surgery for Parkinsons disease is that it makes movement in the off-medication state more like the movement in the on-medication state. In addition, it can reduce levodopa-induced dyskinesias, either by a direct suppressive effect or indirectly by allowing some reduction in anti-parkinsonian medication. Thus, the procedure is most beneficial for Parkinsons patients who have prominent motor fluctuations, that is that they cycle between states of immobility (off state) and states of better mobility (on state).
Multiple system atrophy (MSA) is a neurodegenerative movement disorder characterized by parkinsonian symptoms and cerebellar symptoms. Sleep disturbances also play a crucial role in MSA. One of the most convincing animal models in MSA research is the PLP α-SYN model, but to date no studies on sleep disturbances in this mouse model, frequently found in MSA patients are available. We identified spectral shifts within the EEG of the model, strikingly resembling results of clinical studies. We also characterized muscle activity during REM sleep, which is one of the key symptoms in REM sleep behavioral disorder. Spectral shifts and REM sleep-linked muscle activity were age dependent, supporting face validity of the PLP α-SYN model. We also strongly suggest our findings to be critically evaluated for predictive validity in future studies. Currently, research on MSA lacks potential compounds attenuating or curing MSA. Future drugs must prove its potential in animal models, for this our study provides
MILWAUKEE, WI - The International Parkinson and Movement Disorder Societys Scientific Issues Committee (MDS-SIC), led by Stella Papa and Un Jung Kang, has commissioned a brief review of the current place of cell-based therapies for Parkinsons disease (PD), and ultimately encourages patients to participate only in cell therapy studies that are part of a research program affiliated with a recognized academic or clinical institution. Theoretically, cell-based therapies, including the use of stem cells, could be used to replace or repair the cells lost or damaged in the disease process, thereby improving symptoms. While advances in cell-based research may ultimately provide potential new therapies for patients with PD, science has yet to fully establish a number of challenging aspects of stem cell therapy including specific cell type, method of administration, clinical effect and long-term safety. Several business enterprises worldwide offer stem cell therapies for PD, making unsubstantiated ...

Introduction. Only a few studies have been conducted to determine the level of knowledge among caregivers about Parkinsons disease (PD). The aim of the current study was to determine the knowledge of PD among caregivers at a movement disorder clinic in Turkey. Methods. We conducted a questionnaire based interview with the subjects in a tertiary care neurology facility in Turkey. The questions were divided into two parts covering the symptomatology and treatment of PD. A questionnaire consisting of 10 questions was applied to the subjects who had to mark the correct option in a stipulated time. Results. Eighty caregivers were included in the study. The caregivers mean age was 47.94 years (SD = 12.40). There were 47 female caregivers (58.8%). The most well-known question was that the number of drugs given to the patient may vary with time (76.3%), whereas the benefit noted in the patients treatment decreases over time was the least known question (11.3%). Discussion. This study is the first ...
Disparities in Access to Deep Brain Stimulation Surgery for Parkinson Disease: Interaction Between African American Race and Medicaid Use Andrew K. Chan, BS 1 ; Robert A. McGovern, MD 1 ; Lauren T.

McKhann II, MD 1 While the actual number of African Americans with PD is unknown, it is clear that there are racial disparities … Parkinson disease is by far the most common cause of the parkinsonian syndrome, accounting for approximately 80% of cases (the remainder being due to other neurodegenerative diseases, such as Lewy body dementia) 1. The researchers found that race, education and income were each significant and independent factors in determining a patients level of disability. No specific test exists to diagnose Parkinsons disease. reported that physicians did not consistently document whether PD patients who were … Disparities in the ...

© 2014 Elsevier Ltd. All rights reserved. Parkinson is a neurodegenerative disease, in which tremor is the main symptom. This paper investigates the use of different classification methods to identify tremors experienced by Parkinsonian patients. Some previous research has focussed tremor analysis on external body signals (e.g., electromyography, accelerometer signals, etc.). Our advantage is that we have access to sub-cortical d ata, which facilitates the applicability of the obtained results into real medical devices since we are dealing with brain signals directly. Local field potentials (LFP) were recorded in the subthalamic nucleus of 7 Parkinsonian patients through the implanted electrodes of a deep brain stimulation (DBS) device prior to its internalization. Measured LFP signals were preprocessed by means of splinting, down sampling, filtering, normalization and rectification. Then, feature extraction was conducted through a multi-level decomposition via a wavelet transform. Finally, artificial

Rosi Goldsmith from Portland, OR. Background- Parkinsons Disease (PD) is a disabling, neurodegenerative movement disorder, affecting over 1.5 million Americans. Non-motor symptoms (NMS) and quality of life (QoL) have increasingly become a focus of PD research over the last 10 years.. Objectives- To explore what contributions massage therapy could make to this focus as part of a multi-modal approach to PD treatment.. Methods- A 63 year old male, diagnosed with PD for 5 years, was seen for 56 sessions of 45-90 min. over 36 weeks. Validated, widely accepted Parkinsons rating scales were administered at study onset, three intermediate points, and conclusion to track motor and NMS and QoL changes, and were supplemented by clinical assessments, narrative reports, medication records, and pain rating scales.. As a proxy measure for parasympathetic response, a fingertip pulse-oximeter monitored heart rate during bodywork interventions of Swedish massage, acupressure, myofascial release and ...
Consuming three or more servings of low-fat dairy each day was associated with a higher risk of being diagnosed with Parkinsons disease (PD) in a large study of U.S. men and women, according to a new paper by Harvard T.H. Chan School of Public Health researchers and colleagues. In addition, drinking more than a single serving of low-fat or skim milk daily appeared to increase the risk compared to those who drink less than a serving per week. The authors did not find a PD association with full-fat dairy consumption.. The study was published in the June 7, 2017 online issue of Neurology, the medical journal of the American Academy of Neurology, and will appear in the July 4, 2017 print issue.. The authors emphasized in the study that the findings do not show that dairy products cause Parkinsons disease, but point to an association. More research is needed before recommendations can be made about dairy consumption.. Our study is the largest analysis of dairy and Parkinsons to date, said lead ...
TY - CHAP. T1 - The phenotypic spectrum of parkinson disease. AU - Pfeiffer, Ronald F.. N1 - Copyright: Copyright 2013 Elsevier B.V., All rights reserved.. PY - 2005. Y1 - 2005. N2 - Parkinsons disease (PD) is the second most common neurodegenerative disorder, trailing only Alzheimers disease. This chapter briefly summarizes some of the epidemiological, genetic, and pathophysiological characteristics of PD. The chapter primarily focuses on the clinical features of the illness and thus provides a frame of reference for comparison with the various animal models of PD. Various environmental factors are hypothesized to be operative in the development of PD. Rural living with its agricultural chemical exposure, certain industrial environments, and even occupations such as teaching and medical professions are reported to confer an increased risk for developing PD. Modern molecular genetic techniques have helped investigators identify a growing number of mutations that produce a phenotypic picture of ...
Many of us easily take the blessing of being able to run, jog and walk for granted, whilst People with Parkinson (PwP) need to make a lot of effort to run, jog and walk. The second most common neurodegenerative disorder in Singapore, Parkinson is long-term and causes difficulties in initiation, co-ordination and control of movements such as standing up and walking. Imbalance and falls are also common and may lead to injuries. As movement becomes difficult, PwP are therefore prone to become inactive, resulting in declining strength, joint flexibility and fitness levels. There is currently no cure for Parkinson, but staying active and regular exercise on top of medication, healthy diets, staying hydrated and getting adequate sleep are ways People with Parkinson can improve their health and well-being, preserve physical function, ease symptoms and enhance quality of life. Join us in cheering PwP on as they face their daily challenges on their Parkinson journey. Your generous donations will help us ...
Recent evidence has shown a greater risk of dementia, in particular Alzheimers disease (AD), in individuals using anticholinergic medications regularly. These drugs are widely used by older adults to treat bladder dysfunction, mood, and pain, and many of them are available without prescription. Since these drugs are often used to treat both motor symptoms and non-motor symptoms in patients with Parkinsons Disease (PD), there is concern for increased risk of dementia. Contrary to expectations, a study in the current issue of the Journal of Parkinsons Disease determined that the cognitive performance of PD patients taking anticholinergic medications did not differ from those who did not.. Principal investigator David J. Burn, Director of the Institute of Neuroscience and Professor of Movement Disorder Neurology at Newcastle University, UK, explained, This is the first study to explore an association between anticholinergic burden and mild cognitive impairment (MCI) in PD participants, and is ...
The molecular mechanism underlying Parkinsons disease (PD), an increasingly common neurodegenerative disease, remains unclear. Long non-coding RNA (lncRNA) plays essential roles in gene expression and human diseases. We hypothesize that lncRNAs are involved in neuronal degeneration of PD. Using microarray, we identified 122 differentially expressed (DE) lncRNAs and 48 DE mRNAs between the circulating leukocytes from PD patients and healthy controls. There were 714 significant correlations (r ≥ 0.8 or ≤−0.8, p
Dysosmia in PD (Parkinsons Disease) may result from changes in the olfactory apparatus or in structures involved in olfactory perception. Previous work1,2 has suggested that deep brain stimulation (DBS) pa-tients have improved odor discrimination in stimulation-on/medication-off state in comparison to their own scores in a stimulation-off/medication-off state. What remains unclear is whether it is the ON state itself or an effect of stimulation that leads to improved olfaction. In this study we evaluate dysosmia in two PD cohorts in the ON state, those treated with medication alone and those treated with medication and DBS. A prospective study geared at improving predictive value of olfactory testing with a battery of psychological tests enrolled 45 PD patients and 44 controls. Of the PD patients, 9 had bilateral STN (subthalamic nucleus) DBS and 36 were medically treated. Subset analysis of PD patients with and without DBS placement revealed no difference in apathy or depression. DBS patients had
Timed walking tests are valid measurements to predict community walking in patients with Parkinson disease, say authors of an article published online in Journal of Rehabilitation Medicine. However, evaluation of community walking also should include an assessment of fear of falling, they add. For this investigation, researchers used data from baseline assessments in a randomized clinical trial. A total of 153 patients with Parkinson disease were included. Community walking was evaluated using the mobility domain of the Nottingham Extended Activities of Daily Living Index. Patients who scored 3 points on item 1 (Did you walk around outside?) and item 5 (Did you cross roads?) were considered community walkers. Gait speed was measured with the 6-meter or 10-meter timed walking test. Age, gender, marital status, disease duration, disease severity, motor impairment, balance, freezing of gait, fear of falling, previous falls, cognitive function, executive function, fatigue, anxiety, and ...
