Pallidal GABA and chorea in Huntington's disease. 1990

Neurochemical correlates of chorea in Huntington's disease were studied using striatal and pallidal tissue taken post mortem from patients with mild and severe chorea. While GABA was decreased in all these areas in Huntington's disease, patients with mild chorea had significantly less GABA in the medial pallidum than did those with severe chorea. There was no relationship between the degree of chorea and concentrations of dopamine or its metabolite. Thus the chorea of Huntington's disease may relate to the balance of residual GABAergic innervation between specific areas of the basal ganglia, consistent with primate models of dyskinesias.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D002819	Chorea	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.

D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.

D006816	Huntington Disease	A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea.
