Posthemiplegic focal limb dystonia: A report of two cases

Posthemiplegic focal limb or hemidystonias are rare movement disorders usually due to vascular lesions of the contralateral basal ganglia. The pathogenesis of posthemiplegic dystonia is unknown and its management is usually difficult. In this paper, we report two patients who suffered from a single limb dystonia and hemidystonia, respectively. In the latter patient, hemidystonia developed due to an ischaemic cerebrovascular accident 2 or 3 months after the recovery of hemiplegia. Computed tomography and magnetic resonance imaging scans showed evidence of contralateral putamen and thalamus infarcts. (C) 1998 Elsevier Science B.V. All rights reserved

Clinical features of 35 patients with Parkinson's disease displaying REM behavior disorder

Objective: To assess and compare the disease severity, the treatment properties and the frequency of motor complications in the patients with Parkinson's disease (PD) having and not having REM steep behavior disorder (RBD)

Two siblings with hiomocystinuria presenting with dystonia and parkinsonism

Movement disorders such as dystonia, chorea or tremor are rarely encountered in patients with homocystinuria. We present 2 siblings with laboratory-confirmed homocystinuria, one with severe generalized dystonia and the other with mild parkinsonism. The movement disorders in our patients appeared in the second and first decades, respectively. (C) 2004 Movement Disorder Society

Psychogenic movement disorders in two children

Two schoolboys with diagnostic criteria for psychogenic movement disorder (PMD) are described: one with bizarre tremor of the right hand and a very slow and cautious gait, another with exaggerated trunk sway and collapses during standing and walking. (C) 2003 Movement Disorder Society

High-dose piracetam is effective on cerebellar ataxia in a patient with cerebellar cortical atrophy

We describe a patient with cerebellar ataxia of degenerative nature who was administered high-dose piracetam in a single-blind trial. Piracetam was demonstrated to be highly effective on tandem gait and gait ataxia in daily doses of 60 g. We suggest piracetam has a potential anti-ataxic effect in human cerebellar ataxia when used in considerably higher doses than those indicated for other purposes. (C) 2003 Movement Disorder Society

Extrapyramidal type rigidity in rheumatoid arthritis

Objectives. We had noted cogwheel rigidity in a number of patients with rheumatoid arthritis (RA). Based on this finding, we aimed to investigate formally the presence of rigidity and cogwheeling in RA patients. Our secondary aim was to survey the co-existence of RA and Parkinson's disease (PD)
