Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA.Glucosylceramidase: A glycosidase that hydrolyzes a glucosylceramide to yield free ceramide plus glucose.

EC 126.96.36.199.Levodopa: The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.Lewy Bodies: Intracytoplasmic, eosinophilic, round to elongated inclusions found in vacuoles of injured or fragmented neurons. The presence of Lewy bodies is the histological marker of the degenerative changes in LEWY BODY DISEASE and PARKINSON DISEASE but they may be seen in other neurological conditions. They are typically found in the substantia nigra and locus coeruleus but they are also seen in the basal forebrain, hypothalamic nuclei, and neocortex.Parkinson Disease, Secondary: Conditions which feature clinical manifestations resembling primary Parkinson disease that are caused by a known or suspected condition.

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.

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.

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 ...
Effects of Coenzyme Q10 (CoQ) in Parkinson Disease - Full Text View - ClinicalTrials.gov
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, ...

Study Shows Promise for Personalized Medicine for Parkinson Disease
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 ...

Efficacy of Transdermal Nicotine, on Motor Symptoms in Advanced Parkinson's Disease - Full Text View - ClinicalTrials.gov
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 ...
Genomewide association study for susceptibility genes contributing to familial Parkinson disease
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 × ...

Parkinson's disease-related Leucine-rich repeat kinase 2 modulates nuclear morphology and genomic stability in striatal...
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
Animal model of Parkinson s disease reveals striking sensitivity to common environmental toxins
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 ...

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 ...

IJMS | Free Full-Text | Neuroprotective and Therapeutic Strategies against Parkinson's Disease: Recent Perspectives | HTML
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
No association between Parkinson disease and autoantibodies against NMDA-type glutamate receptors | Translational...
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

Hereditary Early-Onset Parkinson's Disease Caused by Mutations in PINK1 | Science
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 ...

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 ...
Pain management in patients with Parkinson's disease: challenges a | JMDH
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's Disease - an appeal for common sense. Find the cause! - WeeksMD
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 (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. ...

Mutation of leucine-rich repeat kinase 2 (LRRK2) causes an autosomal dominant and late-onset familial Parkinsons disease (PD). FAK activation through different mechanisms that are the advertising of autoinhibition and/or the recruitment of phosphatases, such as for example SHP-2. continues to be connected with an autosomal dominant, late-onset type of familial Parkinsons disease (PD). The encoded proteins, LRRK2, is approximately 280 kDa in proportions and contains many useful domains, including a serine/threonine kinase area . Among the PD-related pathogenic mutations discovered throughout the whole gene , the G2019S mutation, which enhances kinase activity , continues to be within both familial and sporadic PD [4,5]. Many reports have sought to recognize the kinase substrates of LRRK2 to boost our knowledge of LRRK2-mediated PD pathogenesis, and LRRK2 provides been proven to govern different biological features, including neurite outgrowth, cell MEK162 inhibitor database migration, ...
Mechanisms of Parkinson's Disease: Lessons from Drosophila. | MRC Mitochondrial Biology Unit
The power of Drosophila genetics has attracted attention in tackling important biomedical challenges such as the understanding and prevention of neurodegenerative diseases. Parkinsons disease (PD) is the most common neurodegenerative movement disorder which results from the relentless degeneration of midbrain dopaminergic neurons. Over the past two decades tremendous advances have been made in identifying genes responsible for inherited forms of PD. The ease of genetic manipulation in Drosophila has spurred the development of numerous models of PD, including expression of human genes carrying pathogenic mutations or the targeted mutation of conserved orthologs. The genetic and cellular analysis of these models is beginning to reveal fundamental insights into the pathogenic mechanisms. Numerous pathways and processes are disrupted in these models but some common themes are emerging. These often implicate aberrant synaptic function, protein aggregation, autophagy, oxidative stress, and ...
Background: Mild cognitive impairment (MCI) may be accompanied by extra pyramidal signs (EPS), which are related to the severity and type of cognitive impairment. We aimed to elucidate further the relationship between MCI and EPS, analyzing the correlation between the severity of EPS and cognitive functions, and the presence of EPS and neuro-psychiatric features.. Methods: Data were obtained from a longitudinal study of 150 MCI outpatients. Participants underwent a clinical assessment including the Unified Parkinson Disease Rating Scale, the Neuropsychiatric Inventory, the Tinetti Scale, and a standardized neuropsychological battery. Mild EPS could be defined as being present (MCI with mild EPS) using a subscale of UPDRS, based on three specific symptoms: bradykinesia, rigidity and tremor.. Results: The two groups, one with mild EPS (24%) and one without EPS (76%), differed in gait abnormalities and presence of extrapyramidal symptoms. Groups did not differ in terms of general cognitive ...
Recherche uO Research: Motor Deficits in an Alpha-Synuclein Mouse Model of Parkinson's Disease are not Exacerbated by Gba1...
Parkinsons disease is a movement disorder characterized by nigrostriatal dopamine pathway degeneration and neuronal α-synuclein accumulation. Pathogenesis is associated with mutations in α-synuclein and Gba1 encoding alleles. Animal models created to date do not recapitulate the spectrum of clinical disease features. This thesis characterizes the bi-genic Synergy mouse, hypothesized to demonstrate motor behavioural and histological abnormalities downstream of α-synuclein overexpression and mutated Gba1. Synergy and SNCA mice (overexpressed α-synuclein with wild-type Gba1) have early onset deficits in motor coordination, muscle strength and nest building. Both exhibit increased α-synuclein concentration in the brain and cerebellar inclusions positive for two markers of pathological α-synuclein processing. Overall mutant Gba1 expression within Synergy mice does not worsen the behaviour or the histopathological findings associated with overexpression of human α-synuclein in SNCA mice. ...
How valid is the clinical diagnosis of Parkinson's disease in the community? | Journal of Neurology, Neurosurgery & Psychiatry
The results of this study, on a community level, correspond with results from pathological studies indicating that Parkinsons disease is often confused with other disorders. The main areas of diagnostic difficulty concern the distinction from other types of isolated, late onset tremor, vascular parkinsonism, and atypical types of parkinsonism, which are often mistakenly diagnosed as Parkinsons disease. On the other hand, patients with Parkinsons disease are sometimes not recognised as having this disorder, particularly those with mild disease or a relatively isolated tremor.. The rate of underdiagnosis is likely to be even higher, as we included only patients who had already come to medical attention with tremor or parkinsonian features. Some patients not meeting our screening criteria, particularly elderly people with akinetic-rigid parkinsonism without tremor, would have been missed in this study if postural instability and other parkinsonian features were attributed to old age. In door to ...
A molecular signature in blood identifies early Parkinson's disease | Molecular Neurodegeneration | Full Text
The results of this study support our hypothesis that there are blood gene biomarkers that can distinguish early PD patients from normal control subjects. Notably, 38 out of the 62 Parkinson cases in the mild/early cohort were de novo and so, not treated with any antiparkinsonism drug when the blood samples were obtained while the rest were collected during the first year of medication. This suggests that the genetic signature could be an early diagnostic marker for PD. In support, the classifier model performed equally well in early stage de novo PD samples, producing a similar ROC AUC value to that obtained with the entire early PD cohort (de novo and medicated), indicating that patient medication had no significant effect on the PP of the classifier for PD risk and that the model is stable throughout the two PD groups. Supporting this concept, it was recently shown in a population of asymptomatic LRRK2 mutation carriers, that reduced CSF amyloid β and tau species correlated with lower ...

Pedunculopontine nucleus stimulation improves gait freezing in Parkinson disease. - Physiology, Anatomy and Genetics
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.

Ιατρικά Άρθρα Αλέξανδρος Γ. Σφακιανάκης: Dopaminergic Therapies for Non-motor Symptoms in Parkinson's Disease
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 ...

Personality and addictive behaviours in early Parkinson's disease and REM sleep behaviour disorder. - Oxford Neuroscience
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

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 ...
KEGG PATHWAY: Parkinson's disease - Homo sapiens (human)
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 and Cognitive Decline in Parkinson s Disease | Parkinson's Disease
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. ...

Lentiviral vector delivery of parkin prevents dopaminergic degeneration in an alpha-synuclein rat model of Parkinson's disease ...
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
Stress takes its toll in Parkinson's disease
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 ...

What are the benefits of DBS surgery? What are the risks of DBS surgery? | Bachmann Strauss Dystonia & Parkinson Foundation,...
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

Resting tremor classification and detection in Parkinson's disease patients - Nuffield Department of Clinical Neurosciences
© 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.

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 ...
Use of Anticholinergic Drugs Does Not Increase Risk for Dementia in Parkinson's Disease Patients - Healthcanal.com
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 ...
Frontiers | Dysregulated Long Non-coding RNAs in Parkinson's Disease Contribute to the Apoptosis of Human Neuroblastoma Cells |...
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
"DBS-implanted Parkinson's Disease Patients" by Mary Linton Peters, Paula Ravin et al.
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

AU - Thompson, Leah. AU - Vincent, Amy. PY - 2013. Y1 - 2013. N2 - Telerehabilitation may be an alternative service delivery model for people with Parkinson disease (PD) who live in areas where traditional rehabilitation services are not readily accessible. The aim of this study was to determine the accuracy and reliability of performing remote physical assessments of people with PD via telerehabilitation when compared with traditional face-to-face assessments. Twelve subjects were simultaneously examined by a face-to-face investigator and a remote investigator via the eHAB telerehabilitation system. The outcome measures evaluated included the timed stance test, Timed "Up and Go" test, step test, steps in 360 degree turn, Berg Balance Scale, and lateral and functional reach tests.

A primer on Parkinson's disease - HT Health
What can we expect? What is his life expectancy? How is this treated? -- B.B.. ANSWER: Parkinsons disease, PD, is estimated to affect a million North Americans. Its a difficult illness -- difficult to have, difficult to treat and difficult to understand. Most of the time, the illness strikes people over the age of 60, and most cases of Parkinsons disease are not inherited.. The underlying problem is a depletion of dopamine, a brain chemical that is vital to smooth, coordinated muscle movement and to thinking. Four prominent signs distinguish this illness. One is tremor, a shaking of the hands when theyre at rest, as they are when theyre lying in the lap. The index finger and thumb constantly roll over each other. Muscle rigidity is obvious when a doctor tries to move the arms or legs of the patient. They tend to be tightly frozen. Parkinsons patients find it hard to button a shirt or tie shoes. Bradykinesia, slowness of movement, is another sign of PD. Typically, patients walk with slow, ...

RESULTS Of the 762 patients included in the study (mean [SD] age, 70 [9.1] years), 381 received physiotherapy and occupational therapy and 381 received no therapy. At 3 months, there was no difference between groups in NEADL total score (difference, 0.5 points; 95%CI, −0.7 to 1.7; P = .41) or Parkinson Disease Questionnaire-39 summary index (0.007 points; 95%CI, −1.5 to 1.5; P = .99). The EuroQol-5D quotient was of borderline significance in favor of therapy (−0.03; 95%CI, −0.07 to −0.002; P = .04). The median therapist contact time was 4 visits of 58 minutes over 8 weeks. Repeated-measures analysis showed no difference in NEADL total score, but Parkinson Disease Questionnaire-39 summary index (diverging 1.6 points per annum; 95%CI, 0.47 to 2.62; P = .005) and EuroQol-5D score (0.02; 95%CI, 0.00007 to 0.03; P = .04) showed small differences in favor of therapy. There was no difference in adverse events ...

FDA approves deep brain stimulation for people with Parkinson's disease with recent onset of motor complications - NeuroNews...
Strong clinical evidence demonstrates that, when compared to the best medical treatment alone, Medtronic DBS Therapy offers Parkinsons patients with recent onset of motor fluctuations and dyskinesias not adequately controlled with medication a higher likelihood of symptom improvement. Historically, the therapy has often not been considered until symptoms have had a significant impact on quality of life," said Mahlon DeLong, the W P Timmie professor of neurology at Emory University School of Medicine, USA. "This decision by the FDA is significant in that Medtronic DBS Therapy may be considered before the symptoms and complications of disease become severe. Parkinsons patients should be referred to an experienced DBS multidisciplinary centre for a comprehensive evaluation of possible Medtronic DBS therapy. For patients who are still functioning socially and able to work, this may translate into improved quality of life and an overall reduction of the burden of disease." ...
