Sydenham's Chorea

Sydenham’s chorea is a delayed complication of group Aßhaemolytic streptococcal infections and forms one of the majorcriteria of acute rheumatic fever.It is characterised bychorea, muscular weakness, and a number of neuropsychiatricsymptoms. It is considered to be an autoantibody mediated disorderwith the evidence suggesting that patients with Sydenham’schorea produce antibodies that cross reac...

Huntington's chorea.

The pharmacological treatment of Huntington's chorea has been based on the use of neuroleptic drugs, on the hypothesis that there is a functional dopaminergic hyperactivity in this illness (Agid, 1975). More recently, after the observation of reduced cholinergic and GABAminergic activity at the striatal level in brains of choreic subjects (McGeer et al., 1973; Stahl and Swanson, 1974; Bird and ...

Sydenham's chorea.

Sydenham's chorea (SC) is a disorder of the central nervous system (CNS) characterized by sudden, involuntary, arrhythmic, clonic, and purposeless movements. SC appears to provide a model for understanding various neuropsychiatric dysfunctions. Its relationship with attentional deficits, obsessive-compulsive symptoms (OCS) as well as movement disorders provides support for the hypothesis of the...

Chorea Gravis

[Huntington's chorea].

The possibility that Huntington's chorea might be due to a genetically determined biochemical derangement has been raised on a number of occasions. In 1963,Kenyon and Hardy suggested that abnormalities of magnesium metabolism might account for some of the features of Huntington's chorea and in a group of patients investigated the cellular magnesium levels using the Szvenk-Fekete titration metho...

Huntington's chorea.

Huntington's chorea is an hereditary disorder of the central nervous system characterized by the appearance in adult life of progressive chorea and dementia, and inherited in single autosomal dominant fashion with complete penetrance. The essential pathological features of Huntington's chorea are a primary loss of cells in the caudate nucleus and the putamen, and similar involvement of the cere...

Severe Sydenham’s chorea (chorea paralytica) successfully treated with plasmapheresis

Sydenham's chorea is often regarded as a relatively benign and self-limiting condition. Treatment is typically symptomatic, although occasionally immunomodulatory therapies are required in severe forms. Here we report a girl who was affected with the severe variant, chorea paralytica, who responded dramatically and rapidly to plasmapheresis, having failed other therapies.
