Background: Klinefelter’s syndrome (KS) has been associated with tremor, but reports on tremor phenomenology and treatment are limited. Case Reports: Patient 1 is a 17-year-old male with a dystonic tremor treated with deep brain stimulation (DBS). Patient 2 is a 57-year-old male with a predominant left hand resting tremor and dystonic features. Discussion: Our cases suggest that the tremor in p...

We report the case of a 45-year old female multiple sclerosis patient, who accidentally was overdosed with 4-aminopyridine which resulted in dystonic, choreathetoid type abnormal movements in the four limbs, motoric distress, confusion and opisthotonus. There is little known about 4-aminopyridine toxicity. There are only a few reported cases ranging from mild paresthesias to tonic-clonic seizur...

drug induced dystonic reactions are among common presentations of patients in emergency departments, and typically occur with antidopaminergic agents as their extra-pyramidal side effects. dystonic reactions usually occur within the first few hours or days after commencing a drug or dose increase. unlike other extra-pyramidal side effects, a patient may experience acute dystonic reactions (adrs...

Tremor is one of the most frequent movement disorders and covers a wide spectrum of entities summarized in the 1998 consensus statement of the Movement Disorder Society. Essential tremor and Parkinson tremor are most common and are also the most thoroughly studied. Major progress has occurred in the clinical semiology, neuroimaging, epidemiology, and pathophysiology of tremors. Pathology and ge...

We describe a patient with a combination of dystonic and parkinsonian signs. Paraclinical studies revealed a mutation in the GTP cyclohydrolase I gene (GCH1) and a decrease in [123I]-N-omega-fluoropropyl-2beta-carbomethoxy-3beta-(4-iodophenyl) nortropane (123I-FP-CIT) binding ratios indicative of Parkinson's disease. We conclude that the patient probably suffers from a variant of dopa-responsiv...

BACKGROUND A 37-year-old female with a hyperkinetic movement disorder due to chorea-acanthocytosis developed severe painful degenerative arthritis of her left knee as a consequence of repetitive involuntary flexion and extension dystonic and ballistic movements. CASE REPORT Despite profound limitation in her mobility a total knee replacement was successfully undertaken. DISCUSSION The case ...
