An attitude or posture due to the co-contraction of agonists and antagonist muscles in one region of the body. It most often affects the large axial muscles of the trunk and limb girdles. Conditions which feature persistent or recurrent episodes of dystonia as a primary manifestation of disease are referred to as DYSTONIC DISORDERS. (Adams et al., Principles of Neurology, 6th ed, p77)
Acquired and inherited conditions that feature DYSTONIA as a primary manifestation of disease. These disorders are generally divided into generalized dystonias (e.g., dystonia musculorum deformans) and focal dystonias (e.g., writer's cramp). They are also classified by patterns of inheritance and by age of onset.
A condition characterized by focal DYSTONIA that progresses to involuntary spasmodic contractions of the muscles of the legs, trunk, arms, and face. The hands are often spared, however, sustained axial and limb contractions may lead to a state where the body is grossly contorted. Onset is usually in the first or second decade. Familial patterns of inheritance, primarily autosomal dominant with incomplete penetrance, have been identified. (Adams et al., Principles of Neurology, 6th ed, p1078)
A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.
Drugs used in the treatment of movement disorders. Most of these act centrally on dopaminergic or cholinergic systems. Among the most important clinically are those used for the treatment of Parkinson disease (ANTIPARKINSON AGENTS) and those for the tardive dyskinesias.
Excessive winking; tonic or clonic spasm of the orbicularis oculi muscle.
A syndrome characterized by orofacial DYSTONIA; including BLEPHAROSPASM; forceful jaw opening; lip retraction; platysma muscle spasm; and tongue protrusion. It primarily affects older adults, with an incidence peak in the seventh decade of life. (From Adams et al., Principles of Neurology, 6th ed, p108)
The representation of the phylogenetically oldest part of the corpus striatum called the paleostriatum. It forms the smaller, more medial part of the lentiform nucleus.
A sustained and usually painful contraction of muscle fibers. This may occur as an isolated phenomenon or as a manifestation of an underlying disease process (e.g., UREMIA; HYPOTHYROIDISM; MOTOR NEURON DISEASE; etc.). (From Adams et al., Principles of Neurology, 6th ed, p1398)

Toxic proteins produced from the species CLOSTRIDIUM BOTULINUM. The toxins are synthesized as a single peptide chain which is processed into a mature protein consisting of a heavy chain and light chain joined via a disulfide bond. The botulinum toxin light chain is a zinc-dependent protease which is released from the heavy chain upon ENDOCYTOSIS into PRESYNAPTIC NERVE ENDINGS. Once inside the cell the botulinum toxin light chain cleaves specific SNARE proteins which are essential for secretion of ACETYLCHOLINE by SYNAPTIC VESICLES. This inhibition of acetylcholine release results in muscular PARALYSIS.
Drugs used for their actions on skeletal muscle. Included are agents that act directly on skeletal muscle, those that alter neuromuscular transmission (NEUROMUSCULAR BLOCKING AGENTS), and drugs that act centrally as skeletal muscle relaxants (MUSCLE RELAXANTS, CENTRAL). Drugs used in the treatment of movement disorders are ANTI-DYSKINESIA AGENTS.

A portion of the nucleus of ansa lenticularis located medial to the posterior limb of the internal capsule, along the course of the ansa lenticularis and the inferior thalamic peduncle or as a separate nucleus within the internal capsule adjacent to the medial GLOBUS PALLIDUS (NeuroNames, http://rprcsgi.rprc. washington.edu/neuronames/ (September 28, 1998)). In non-primates, the entopeduncular nucleus is analogous to both the medial globus pallidus and the entopeduncular nucleus of human.
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.
(GTP cyclohydrolase I) or GTP 7,8-8,9-dihydrolase (pyrophosphate-forming) (GTP cyclohydrolase II). An enzyme group that hydrolyzes the imidazole ring of GTP, releasing carbon-8 as formate. Two C-N bonds are hydrolyzed and the pentase unit is isomerized. This is the first step in the synthesis of folic acid from GTP. EC 3.5.4.16 (GTP cyclohydrolase I) and EC 3.5.4.25 (GTP cyclohydrolase II).
Diseases of the BASAL GANGLIA including the PUTAMEN; GLOBUS PALLIDUS; claustrum; AMYGDALA; and CAUDATE NUCLEUS.

Involuntary, forcible, rapid, jerky movements that may be subtle or become confluent, markedly altering normal patterns of movement. Hypotonia and pendular reflexes are often associated. Conditions which feature recurrent or persistent episodes of chorea as a primary manifestation of disease are referred to as CHOREATIC DISORDERS. Chorea is also a frequent manifestation of BASAL GANGLIA DISEASES.
Conditions characterized by pain involving an extremity or other body region, HYPERESTHESIA, and localized autonomic dysfunction following injury to soft tissue or nerve. The pain is usually associated with ERYTHEMA; SKIN TEMPERATURE changes, abnormal sudomotor activity (i.e., changes in sweating due to altered sympathetic innervation) or edema. The degree of pain and other manifestations is out of proportion to that expected from the inciting event. Two subtypes of this condition have been described: type I; (REFLEX SYMPATHETIC DYSTROPHY) and type II; (CAUSALGIA). (From Pain 1995 Oct;63(1):127-33)

The age, developmental stage, or period of life at which a disease or the initial symptoms or manifestations of a disease appear in an individual.
Abnormal involuntary movements which primarily affect the extremities, trunk, or jaw that occur as a manifestation of an underlying disease process. Conditions which feature recurrent or persistent episodes of dyskinesia as a primary manifestation of disease may be referred to as dyskinesia syndromes (see MOVEMENT DISORDERS). Dyskinesias are also a relatively common manifestation of BASAL GANGLIA DISEASES.

DYT1 mutation in French families with idiopathic torsion dystonia. (1/432)

A GAG deletion at position 946 in DYT1, one of the genes responsible for autosomal dominant idiopathic torsion dystonia (ITD), has recently been identified. We tested 24 families and six isolated cases with ITD and found 14 individuals from six French families who carried this mutation, indicating that 20% of the affected families carried the DYT1 mutation. Age at onset was always before 20 years (mean, 9+/-4 years). Interestingly, the site of onset was the upper limb in all but one patient. Dystonia was generalized in seven patients and remained focal or segmental in three patients. The absence of common haplotypes among DYT1 families suggests that at least six independent founder mutations have occurred. In addition, one Ashkenazi Jewish family carried the common haplotype described previously in Ashkenazi Jewish patients, but it was absent in the other family. Moreover, the dystonia remained focal in the latter family when compared with the usual generalized phenotype in patients with the common Ashkenazi Jewish haplotype. This indicates that there are at least two founder mutations in this population.  (+info)

Human deafness dystonia syndrome is a mitochondrial disease. (2/432)

The human deafness dystonia syndrome results from the mutation of a protein (DDP) of unknown function. We show now that DDP is a mitochondrial protein and similar to five small proteins (Tim8p, Tim9p, Tim10p, Tim12p, and Tim13p) of the yeast mitochondrial intermembrane space. Tim9p, Tim10p, and Tim12p mediate the import of metabolite transporters from the cytoplasm into the mitochondrial inner membrane and interact structurally and functionally with Tim8p and Tim13p. DDP is most similar to Tim8p. Tim8p exists as a soluble 70-kDa complex with Tim13p and Tim9p, and deletion of Tim8p is synthetically lethal with a conditional mutation in Tim10p. The deafness dystonia syndrome thus is a novel type of mitochondrial disease that probably is caused by a defective mitochondrial protein-import system.  (+info)

Association of a missense change in the D2 dopamine receptor with myoclonus dystonia. (3/432)

Hereditary autosomal dominant myoclonus dystonia (MD) is a movement disorder characterized by involuntary lightning jerks and dystonic movements and postures alleviated by alcohol. Although various large families with MD have been described, no positive linkage has been found to a chromosomal location. We report a family with eight members with MD. Linkage analysis identified a 23-centimorgan region on chromosome 11q23 that cosegregates with the disease state (maximum multipoint logarithm of odds score = 2.96 at D11S897). This region contains an excellent candidate gene for involvement in the etiology of MD, the D2 dopamine receptor (DRD2) gene. Neurotransmission mediated by DRD2 is known to have a key role in the control of movement and also has been implicated in reward and reinforcement mechanisms and psychiatric disorders. Sequencing of the coding region of DRD2 indicated that all affected and obligate carriers were heterozygous for a Val154Ile change in exon 3 of the protein, which is highly conserved across species. This change was found neither in other unaffected members of the pedigree nor in 250 control chromosomes. Our finding provides evidence for the involvement of DRD2 in a disorder of the central nervous system and should lead to further insight into the function of the dopaminergic system in dystonia and other movement and mood disorders.  (+info)

From off-period dystonia to peak-dose chorea. The clinical spectrum of varying subthalamic nucleus activity. (4/432)

The effect of chronic bilateral high-frequency stimulation of the subthalamic nucleus (STN) on levodopa-induced dyskinaesias was investigated in eight patients with fluctuating Parkinson's disease complicated by functionally disabling off-period dystonia. All of the patients also had severe diphasic and peak-dose chorea, so that it was possible to study the effect of high-frequency stimulation on the different types of levodopa-induced dyskinaesias. Off-period fixed dystonia was reduced by 90% and off-period pain by 66%. After acute levodopa challenge, high-frequency stimulation of the STN reduced diphasic mobile dystonia by 50% and peak-dose choreic dyskinaesias by 30%. The effect of bilateral high-frequency stimulation of the STN on the Unified Parkinson's Disease Rating Scale motor score had the same magnitude as the preoperative effect of levodopa. This allowed the levodopa dose to be reduced by 47%. The combination of reduced medication and continuous high-frequency stimulation of the STN reduced the duration of on-period diphasic and peak-dose dyskinaesias by 52% and the intensity by 68%. Acute high-frequency stimulation of the STN mimics an acute levodopa challenge, concerning both parkinsonism and dyskinaesias, and suppresses off-period dystonia. Increasing the voltage can induce repetitive dystonic dyskinaesias, mimicking diphasic levodopa-induced dyskinaesias. A further increase in voltage leads to a shift from a diphasic-pattern dystonia to a peak-dose pattern choreodystonia. Chronic high-frequency stimulation of the STN also mimics the benefit of levodopa on parkinsonism and improves all kinds of levodopa-induced dyskinaesias to varying degrees. Off-period dystonia, associated with neuronal hyperactivity in the STN is directly affected by stimulation and disappears immediately. The effect of chronic high-frequency stimulation of the STN on diphasic and peak-dose dyskinaesias is more complex and is related directly to the functional inhibition of the STN and indirectly to the replacement of the pulsatile dopaminergic stimulation by continuous functional inhibition of the STN. Chronic high-frequency stimulation of the STN allows a very gradual increase in stimulation parameters with increasing beneficial effect on parkinsonism while reducing the threshold for the elicitation of stimulation-induced dyskinaesias. In parallel with improvement of parkinsonism, the levodopa dose can be gradually decreased. As diphasic dystonic dyskinaesias are improved to a greater degree than peak-dose dyskinaesias, both direct and indirect mechanisms may be involved. Peak-dose choreatic dyskinaesias, associated with little evidence of parkinsonism and thus with low neuronal activity in the STN, are improved, mostly indirectly. Fixed off-period dystonia, mobile diphasic dystonia and peak-dose choreodystonia seem to represent a continuous clinical spectrum reflecting a continuous spectrum of underlying activity patterns of STN neurons.  (+info)

Generalised muscular weakness after botulinum toxin injections for dystonia: a report of three cases. (5/432)

Three patients are reported on who developed transient generalised weakness after receiving therapeutic doses of botulinum toxin for cervical dystonia (one case) and symptomatic hemidystonia (two cases) respectively. Clinical and electrophysiological findings were in keeping with mild botulism. All patients had received previous botulinum toxin injections without side effects and one patient continued injections without recurrence of generalised weakness. The cause is most likely presynaptic inhibition due to systemic spread of the toxin. Patients with symptomatic dystonia may be more likely to have this side effect and botulinum toxin injections in these patients should be carried out cautiously.  (+info)

Clinical genetics of familial progressive supranuclear palsy. (6/432)

Recent studies have shown that progressive supranuclear palsy (PSP) could be inherited, but the pattern of inheritance and the spectrum of the clinical findings in relatives are unknown. We here report 12 pedigrees, confirmed by pathology in four probands, with familial PSP. Pathological diagnosis was confirmed according to recently reported internationally agreed criteria. The spectrum of the clinical phenotypes in these families was variable including 34 typical cases of PSP (12 probands plus 22 secondary cases), three patients with postural tremor, three with dementia, one with parkinsonism, two with tremor, dystonia, gaze palsy and tics, and one with gait disturbance. The presence of affected members in at least two generations in eight of the families and the absence of consanguinity suggests autosomal dominant transmission with incomplete penetrance. We conclude that hereditary PSP is more frequent than previously thought and that the scarcity of familial cases may be related to a lack of recognition of the variable phenotypic expression of the disease.  (+info)

Abnormal cortical processing of voluntary muscle relaxation in patients with focal hand dystonia studied by movement-related potentials. (7/432)

In order to clarify the abnormality in cortical motor preparation for voluntary muscle relaxation of the hand in patients with focal hand dystonia, Bereitschaftspotentials (BPs) preceding voluntary muscle contraction and relaxation were recorded in eight patients (three with simple writer's cramp and five with dystonic writer's cramp), and were compared with those from 10 normal subjects. Voluntary muscle relaxation: after keeping the right wrist in an extended position for > 5 s, the subject let the hand drop by voluntarily terminating muscle contraction of the wrist extensor without any associated muscle contraction. Voluntary muscle contraction: the right wrist was flexed by voluntarily contracting the wrist flexor muscle. Scalp EEGs were recorded from 11 electrodes placed over the frontal, central and parietal areas. In the control group, the BP measured at the movement onset was maximal at the left central area (C1), and distributed predominantly over the left hemisphere equally in both the contraction and relaxation tasks. In the focal hand dystonia group, BP was maximal at C1 in the contraction task, whereas, in the relaxation task, it was maximal at the midline central area (Cz) and symmetrically distributed. At the left central area, the BP amplitude in the focal hand dystonia group was diminished significantly in the relaxation task compared with the contraction task (P < 0.05). The present results demonstrate for the first time that the cortical preparatory process for voluntary muscle relaxation, or motor inhibition, is abnormal in focal hand dystonia.  (+info)

Risk factors for spread of primary adult onset blepharospasm: a multicentre investigation of the Italian movement disorders study group. (8/432)

OBJECTIVES: Little is known about factors influencing the spread of blepharospasm to other body parts. An investigation was carried out to deterrmine whether demographic features (sex, age at blepharospasm onset), putative risk, or protective factors for blepharospasm (family history of dystonia or tremor, previous head or face trauma with loss of consciousness, ocular diseases, and cigarette smoking), age related diseases (diabetes, hypertension), edentulousness, and neck or trunk trauma preceding the onset of blepharospasm could distinguish patients with blepharospasm who had spread of dystonia from those who did not. METHODS: 159 outpatients presenting initially with blepharospasm were selected in 16 Italian Institutions. There were 104 patients with focal blepharospasm (mean duration of disease 5.3 (SD 1.9) years) and 55 patients in whom segmental or multifocal dystonia developed (mainly in the cranial cervical area) 1.5 (1.2) years after the onset of blepharospasm. Information was obtained from a standardised questionnaire administered by medical interviewers. A Cox regression model was used to examine the relation between the investigated variables and spread. RESULTS: Previous head or face trauma with loss of consciousness, age at the onset of blepharospasm, and female sex were independently associated with an increased risk of spread. A significant association was not found between spread of dystonia and previous ocular diseases, hypertension, diabetes, neck or trunk trauma, edentulousness, cigarette smoking, and family history of dystonia or tremor. An unsatisfactory study power negatively influenced the validity and accuracy of the negative findings relative to diabetes, neck or trunk trauma, and cigarette smoking. CONCLUSIONS: The results of this exploratory study confirm that patients presenting initially with blepharospasm are most likely to experience some spread of dystonia within a few years of the onset of blepharospasm and suggest that head or face trauma with loss of consciousness preceding the onset, age at onset, and female sex may be relevant to spread. The suggested association between edentulousness and cranial cervical dystonia may be apparent because of the confounding effect of both age at onset and head or face trauma with loss of consciousness. The lack of influence of family history of dystonia on spread is consistent with previous findings indicating that the inheritance pattern is the same for focal and segmental blepharospasm.  (+info)

Within the past few years, there has been a renaissance of functional neurosurgery for the treatment of dystonic movement disorders. In particular, deep brain stimulation (DBS) has widened the spectrum of therapeutical options for patients with otherwise intractable dystonia. It has been introduced only with a delay after DBS became an accepted treatment for advanced Parkinson disease (PD). In this overview, the authors summarize the current status of its clinical application in dystonia. Deep brain stimulation for dystonia has been developed from radiofrequency lesioning, but it has replaced the latter largely in most centers. The main target used for primary dystonia is the posteroventral globus pallidus internus (GPi), and its efficacy has been shown in generalized dystonia, segmental dystonia, and complex cervical dystonia. The optimal target for secondary dystonias is still unclear, but some patients appear to benefit more from thalamic stimulation. The improvement of dystonia with chronic DBS

An acute dystonic reaction consists of sustained, often painful muscular spasms, producing twisting abnormal postures. 50% occur within 48 hours of initiation of the neuroleptic. 90% occur within 5 days. These reactions are more common with parental then oral medications. Theyre more common in the younger patients, and more common in males than females in the young age group. Approximately 3 to 10% of patients exposed to neuroleptics will experience an acute dystonic reaction. Haldol and the long acting. injected fluphenazines have the highest incidence of these reactions. The risk is higher in patients with a prior history of a similar reaction or a family history of dystonia. The order of the most frequent types include neck dystonia 30%, tongue dystonia 17%, jaw dystonia 15%, oculorgyric crisis (eyes rolling back, and neck arching) 6%, and opisthotonus (body arching) 3.5%.

Globus pallidus pars interna (GPi) deep brain stimulation (DBS) is efficacious for reduction of medically refractory, primary, generalised dystonia and subtypes of acquired dystonia,1 but there is little evidence supporting the efficacy of DBS in dystonia acquired after stroke or traumatic brain injury (TBI).. Dystonia has been reported in up to 4% of patients with post-stroke2 and up to 20% of patients after severe TBI.3 Patients who develop dystonia after stroke or TBI are typically adolescents/young adults, in whom dystonia manifests in days to years after the initial event. Brain MRI abnormalities are often present, typically in the basal ganglia. The most frequent type of dystonia observed in this population is hemidystonia, which is usually refractory to medical management.3 Since young adults are predominantly afflicted and the dystonia is often medically refractory, this population experiences significant disability for the majority of their lifetime ...

Dystonia in Parhnsons Disease: Clinical and Pharmacological Features W. H. Poewe, MD, A. J. Lees, MD,t and G. M. Stern, M D t We studied the features of dystonia in 9 patients with untreated idiopathic Parkinsons disease and in 56 patients on sustained treatment with L-dopa Dystonia was seen as an initial symptom in patients with both early- and late-onset Parkinsons disease and included action dystonia of the limbs and cranial dystonia Although the coexistence of parkinsonism and dystonia suggests a common pathophysiology, antiparkinsonian drugs did not consistently influence dystonic spasms. L-dopa-induced dystonia was seen as an off-period, biphasic, or peak-dose phenomenon. Each type showed a distinctive pattern of localization of dystonic spasms, possibly reflecting neurochemical aspects of basal ganglia somatotopy. Neuropharmacological studies performed in 12 patients suggest that off-period dystonia is genuinely induced by L-dopa and best relieved by antiparkinsonian agents. Poewe WH, ...

Patients with focal dystonia experience uncontrollable movements of the hand during certain types of skilled movements. Though the origin of the disorder is not fully understood, it is thought that brain areas involved in moving the hands and receiving touch information from the hands, are involved. For example, patients with dystonia affecting the hand show changes in their ability to perceive touch - this is something that typically escapes the patients own awareness. Further, the area of the brain receiving touch information has a disrupted representation of the finger skin surfaces.. The goal of our research is to improve dystonia symptoms in patients with hand dystonia. We will attempt to achieve this goal by implementing an intensive training treatment that requires patients to attend to, and use touch information applied to specific fingertips.

Drug induced movement disorders have been described with an increasing frequency since the introduction of chlorpromazine (thorazine) in 1952.1 This and other dopamine receptor blocking drugs, also referred to as neuroleptic drugs, can cause a wide variety of movement disorders.1 20-22 In 1982, Burkeet al,2 comprehensively characterised tardive dystonia as a variant of tardive dyskinesia in 42 patients exposed to neuroleptic drugs. Since then, tardive dystonia has been widely recognised as a separate entity from tardive dyskinesia, and both can manifest at the same time.1-4 7 10 Studies on tardive dystonia have focused on the prevalence of the anatomical areas involved, and its clinical progression.2 3 7 The craniocervical region has been demonstrated as the most common region initially affected in patients with tardive dystonia.1-4 7 As it is relatively common for patients and their family members to be unaware of an exposure to neuroleptic drugs, the presence of suggestive clinical signs that ...
This study will use transcranial magnetic stimulation to examine how the brain controls muscle movement in focal and generalized types of dystonia. Dystonia is a movement disorder in which involuntary muscle contractions cause uncontrolled twisting or abnormal postures. Dystonia may be focal, involving just one region of the body, such as the hand, neck or face. Focal dystonia usually begins in adulthood. Generalized dystonia, on the other hand, generally begins in childhood or adolescence. Symptoms begin in one area and then become more widespread.. Healthy normal volunteers and patients with focal or generalized dystonia 8 years of age and older may be eligible for this study. First-degree relatives of patients will also be enrolled.. In transcranial magnetic stimulation, an insulated wire coil is placed on the subjects scalp and brief electrical currents are passed through the coil, creating magnetic pulses that pass into the brain. These pulses generate very small electrical currents in the ...
IMPORTANCE Mutations in the GNAL gene have recently been shown to cause primary torsion dystonia. The GNAL-encoded protein (Gαolf) is important for dopamine D1 receptor function and odorant signal transduction. We sequenced all 12 exons of GNAL in 461 patients from Germany, Serbia, and Japan, including 318 patients with dystonia (190 with cervical dystonia), 51 with hyposmia and Parkinson disease, and 92 with tardive dyskinesia or acute dystonic reactions.

As some of you may remember, my official diagnosis is either Early Onset Parkinsons with dystonia that responds to dopamine or Late Onset Dopamine Responsive Dystonia with Parkinsonisms. Either way, the treatment is the same and they are both progressive neuromuscular disorders. The latter is less progressive than Parkinsons, but it is progressive.. And regardless of the diagnosis, Im also a part of the Insomnia Club, at least part of the time. This is an exclusive club to which many people with Parkinsons and Dystonia belong and it consists of informal online meetings anywhere between 1 and 5 am. It was during one of these meetings that I found the following articles and news segment about Dystonia.. The first describes a typical dystonic storm and, for those of us who experience this, how to tell the difference between a dystonic storm and just a worsening of symptoms. The author, Tom Seaman, has probably the best blog out there about dystonia. Once I started reading his articles, I had a ...

Dystonia is a movement disorder in which your muscles contract involuntarily, causing repetitive or twisting movements. This dystonia can affect one muscle, a muscle group or even your entire body. When your masticatory, lower facial and the tongue muscles are affected, it is oromandibular dystonia.. Symptoms:. Dystonia of the neck muscles, larynx, and eyelids are often related to oromandibular dystonia. Symptoms sometimes only occur when you perform specific actions, such as chewing or speaking. In addition, some people may have difficulty in swallowing and chewing.. Causes:. Oromandibular dystonia can be divided into primary one and secondary one. Primary oromandibular dystonia occurs with or without a family history of the disorder, while the secondary one occurs because of secondary causes, such as certain disorders or exposure to drugs.. Diagnosis:. After asking patients about his or her medical information, doctors may perform the following tests to help diagnose this condition:. ...
Opposing muscles often contract simultaneously as if they are competing for control of a body part. These involuntary muscle contractions force the body into repetitive, twisting movements and awkward, irregular postures. There are approximately 13 forms of dystonia, and dozens of diseases and conditions include dystonia as a major symptom. With the recent mapping of genes for idiopathic torsion dystonia and identification of a gene (DYT1) for early-onset dystonia, the description primary or idiopathic dystonia has evolved. However, continuing to use primary torsion dystonia to classify a group of dystonias as a clinical group of movement disorders is justifiable because dystonia is the primary abnormality attributable to this condition. The following case illustrates chiropractic presentation of a primary dystonia: ICD-9 333.79 (an acquired dystonia).. Case History. A wheelchair-bound, mid-30s female presented to my office on medical referral. Her record indicated she had suffered an MMR ...
February 3, 2009 /Press Release/ -- Mount Sinai researchers have identified mutations in gene THAP1 as a cause for primary torsion dystonia. This is the second gene identified for this type of dystonia. The study was published online on February 1st in Nature Genetics. Mount Sinai worked with Beth Israel Medical Center on this research, which was partly funded by The Bachmann-Strauss Dystonia & Parkinson Foundation, the Dystonia Medical Research Foundation and the National Institute of Neurological Disorders and Stroke (NINDS).. Dystonia is a movement disorder that causes muscles to contract and spasm involuntarily and is characterized by twisting movement and abnormal postures. According to The Bachmann-Strauss Dystonia & Parkinson Foundation, dystonia affects an estimated 500,000 people in North America. At least 15 different types of dystonia are considered to be genetic.. Researchers discovered a mutation in the THAP1 gene in three Amish-Mennonite families with mixed-onset primary torsion ...
Cervical Dystonia. Cervical dystonia is also called torticollis as it affects the muscles in the neck. The muscles in the neck control the movement of the head. Individuals with this disorder are only able to move their heads on one side and have difficulty moving it backwards or forwards. It can affect a person at any age although it is often associated with birth injuries.. Blepharospasm Blepharospasm is the second most common type of focal dystonia. In this type of dystonia, there is an uncontrollable contraction of the muscles that cause the eye to blink. This can lead to increased blinking in both the eyes. This type of dystonia disorder can also lead to spasms in eye which may result in functional blindness even though the eye itself is healthy.. Cranio-facial Dystonia. This type of focal dystonia occurs when the muscles of the head, face and neck are affected. When muscles of the jaw, lip and tongue are affected, it can cause problems in swallowing and speech and there can be difficulty ...
It is possible to receive disability for dystonia. However, the Social Security Administration will need proof that dystonia is keeping an individual from working. They will conduct an assessment of the restrictions dystonia is placing on the individual and if these restrictions affect their ability to work. Inabilities to carry, push, walk, run, lift or speak are all considered disabling to some degree.. It will be necessary for individuals applying for social security disability benefits to disclose how dystonia influences their daily lives. For example, if they find it hard to drive, that information will be needed for the SSAs evaluation. If the muscle contractions result in severe chronic pain, that may also be considered disabling.. It is helpful to have a primary care physician write up the limitations involved with a particular case of dystonia to present to the SSA. Individuals should provide this with a copy of all medical records from the onset of the dystonia to this present. These ...

These motor symptoms can have a major impact on disability. Treatment with botulinum toxin injections aims to reduce motor symptoms, and therefore disability. Despite motor improvements, many patients still experience difficulties with performing daily life activities. To optimize treatment, other factors that determine disability should be identified.OBJECTIVE: To explore and identify clinical characteristics that relate to disability in CD.METHODS: Data on disability, severity of dystonia, anxiety, depression, pain and quality of life of 96 CD patients was analyzed with a ...

A disabling form of tardive dystonia and dyskinesia in a young schizophrenic patient is reported. Severe forms of dystonia plus dyskinesia associated with long term neuroleptic exposition are not rare. Although tomographic scans were normal, blood perfusion examination through single photon computed tomography (SPECT) showed basal ganglia hypoperfusion, indicating striatum involvement in this late neuroleptic side effect. The patient was treated with relative success by the association of high doses of propranolol, diazepan and biperiden. A critical discussion about some clinical, neurobiological and treatment issues related to severe forms of tardive dystonia is presented. The association of beta-adrenergic antagonists, gaba agonists and anticholinergic drugs are suggested as a possible alternative for the treatment of this condition ...

Torsion dystonia, also known as dystonia musculorum deformans, is a disease characterized by painful muscle contractions resulting in uncontrollable distortions. This specific type of dystonia is frequently found in children, with symptoms starting around the ages of 11 or 12. It commonly begins with contractions in one general area such as an arm or a leg that continue to progress throughout the rest of the body. It takes roughly 5 years for the symptoms to completely progress to a debilitating state. The disease is caused by a genetic disorder which results in a defect in a protein called Torsin A. A mutation in the DYT1 gene causes the loss of an amino acid, glutamic acid, in the Torsin A protein. The defective protein creates a disruption in communication in neurons that control muscle movement and muscle control. This mutation is most usually inherited from a parent, but can occur sporadically. The disease is caused by a dominant allele, meaning that the person affected needs only one copy ...
Cervical dystonia may be primary (meaning that it is the only apparent neurological disorder, with or without a family history) or be brought about by secondary causes such as physical trauma. In cervical dystonia, the neck muscles contract involuntarily. If the contractions are sustained, they may cause abnormal posture of the head and neck. If the spasms are periodic or patterned, they may produce jerky head movements. (1) ...

In task-specific focal hand dystonia (tspFHD), the temporal dynamics of cortical activity in the motor system and how these processes are related to impairments in sensory and motor function are poorly understood. Here, we use time-frequency reconstructions of magnetoencephalographic (MEG) data to elaborate the temporal and spatial characteristics of cortical activity during movement. A self-paced finger tapping task during MEG recording was performed by 11 patients with tspFHD and 11 matched healthy controls. In both groups robust changes in beta (12-30Hz) and high-gamma (65-90Hz) oscillatory activity were identified over sensory and motor cortices during button press. A significant decrease (p

Patient 1 was a 47-year-old woman who presented with paroxysmal abnormal movement since childhood. She was first seen in 2004. The attack was characterised by dystonic painful posture with upward or downward deviation of the eyes, head turning, shoulder abduction and extensions, lower limb dystonia, impaired speech, and occasionally stepping movements, with preserved consciousness. The attacks lasted for 1 to 2 minutes with a frequency of up to 8 times a day. Each attack was precipitated by stress or being startled, for example, being approached by a car unexpectedly when crossing the road, frightened by a cockroach, a sudden phone call, or an abrupt movement. Occasionally, the attack could occur during sleep. There was no incontinence. The patient had normal intelligence. Physical examination, biochemical tests, computed tomography of the brain, and electroencephalography were normal. The attacks were controlled with carbamazepine and frequency of attacks reduced to fewer than 3 times a day and ...
Botulinum toxin (BTX) is used in various fields of medicine, including the treatment of hyperhidrosis and cervical dystonia. Botox®, Dysport®, Xeomin® and NeuroBloc® are commercially available BTX products, which are formulated differently and their dosing units are unique. Dosage and concentration of the prepared solution for injection varies considerably among studies comparing the products. Improved guidelines on concentration and dosing when changing from one product to another are warranted. This would ensure the use of the lowest effective doses for good effect, minimal risk of antibody formation and side-effects as well as reduced costs.. The aim of the present work was to find the most appropriate BTX concentration for each of the four products to achieve the highest sweat reducing effect and to investigate dose conversion ratios between Botox and Dysport in the treatment of cervical dystonia when the products are diluted to the same concentration, 100 U/ml..
