Complex regional pain syndrome (CRPS) may lead to movement disorders (MDs) in some patients. Reliable information on the nature, chronology and clinical determinants of MDs in CRPS patients is lacking but could provide better insight in to the underlying pathophysiological mechanism. We retrospectively evaluated the clinical and temporal characteristics of MDs in patients with CRPS. Cox's propo...

Twenty-three children (aged less than 18 years) and 17 adults with severe widespread dystonia were treated with high doses of benzhexol (up to 130 mg daily introduced slowly over many weeks). Children tolerated higher doses (median 30 mg/day) than adults (median 20 mg/day). 52% of the children gained useful benefit, many (43%) without unwanted side effects. Such an approach was less successful ...

Musician's dystonia is generally considered a sporadic disorder. We present three families with the index patient affected by musician's dystonia, but other forms of upper limb focal task-specific dystonia (FTSD), mainly writer's cramp, in seven relatives. Our results suggest a genetic contribution to FTSD with phenotypic variability, including musician's dystonia.

Clinical characteristics of 15 consecutively referred patients with tardive dystonia are reported. The onset of tardive dystonia occurred in all age groups and in both sexes, with some preponderance in men. There was considerable overlap with tardive dyskinesia and tardive akathisia. Six subjects reported past acute dystonia, and four had histories of essential tremor, suggesting a vulnerabilit...

BACKGROUND Focal dystonia of acute onset is indicative of a structural lesion in the nervous system. Cerebellar lesions have rarely been associated with dystonia. CASE DESCRIPTION A 42-year-old woman was admitted to the neurology ward because of fever, confusion, and gait unsteadiness. She was diagnosed as having tuberculous meningitis, and, after a few days of antituberculous treatment, she ...

BACKGROUND Myoclonus dystonia is an autosomal dominant dystonia-plus syndrome, characterized by symptom variability within families. Most often is the myoclonus the most debilitating symptom, and many patients report myoclonus reduction after alcohol intake. In several families, mutations in the SGCE gene have been identified. METHOD We report of a three-generation family with myoclonus dysto...

Abstract Date Presented 04/02/2022 Focal task-specific dystonia is a fine motor disorder that affects professional musicians, for whom this diagnosis often career ending. This study explored musicians’ perceptions of the lived experience focal dystonia. The findings suggest client-centered and collaborative approaches to care, highlighting importance addressing emotional factors related chronic...

Abnormalities in the somatosensory system are increasingly being recognized in patients with dystonia. The aim of this study was to investigate whether sensory abnormalities are confined to the dystonic body segments or whether there is a wider involvement in patients with idiopathic dystonia. For this purpose, we recruited 20 patients, 8 had generalized, 5 had segmental dystonia with upper ext...

BACKGROUND The association between Dystonia and Parkinson's disease (PD) has been well described especially for foot and hand dystonia. There is however few data on dystonic postures in patients with atypical parkinsonism. OBJECTIVE To evaluate the frequency and pattern of dystonia in a group of patients with atypical parkinsonism (multiple system atrophy - MSA, progressive supranuclear palsy...

Dystonia, which causes intermittent or sustained abnormal postures and movements, can present in a focal or a generalized manner. In the limbs, focal dystonia can occur in either the upper or lower limbs and may be task-specific causing abnormal motor performance for only a specific task, such as in writer's cramp, runner's dystonia, or musician's dystonia. Focal limb dystonia can be non-task-s...
