Huntington's disease(redirected from Huntington's syndrome)
Also found in: Dictionary, Thesaurus, Encyclopedia.
A rare inherited disease of the central nervous system characterized by progressive dementia, abnormal posture, and involuntary movements. The typical age of onset is between 30 and 50 years. Also called Huntington's chorea.
Etymology: George S. Huntington, American physician, 1851-1916
a rare abnormal hereditary condition characterized by chronic progressive chorea and mental deterioration that results in dementia. An individual afflicted with the condition usually shows the first signs in the fourth decade of life and dies within 15 years. It is transmitted as an autosomal trait and becomes progressively worse in severity as the trinucleotide repeats grow in successive generations. There is no known effective treatment, but symptoms can be relieved with medication.

Huntington's diseaseA rare, dominant, genetic brain disorder caused by a defective gene on chromosome number 4 that has complete penetrance. The disease appears most often in middle-aged adults and leads to loss of nerve cells and a buildup of the neurotransmitter dopamine. This causes involuntary twitching or jerking movements of the face and body (chorea), alternating excitement and depression, and progressive DEMENTIA. The chorea can be controlled by drugs but there is no treatment for the central problem. When the disease starts in childhood the inheritance is four times as likely to be from the father than from the mother. The mechanism of the disease is unknown but it is thought that neural toxicity results from the accumulation of amino-terminal fragments containing an expanded polyglutamine region. (George Huntington, 1850–1916, American General Practitioner)
A rare hereditary condition that causes progressive chorea (jerky muscle movements) and mental deterioration that ends in dementia. Huntington's symptoms usually appear in patients in their 40s. There is no effective treatment.
