Medical Definition of Huntington's disease
: a hereditary brain disorder that is a progressive, neurodegenerative condition marked especially by impairments in thinking and reasoning, disturbances of emotion and behavior, and the involuntary spasmodic movements of chorea and is associated with the loss or atrophy of nerve cells in the basal ganglia especially of the caudate nucleus and putamen ◆Huntington's disease is inherited as an autosomal dominant trait requiring only one parent to pass on a copy of the defective gene on a chromosome other than a sex chromosome. While it may have an onset at any age, people most often become symptomatic between 30 to 50 years of age. The most common symptoms of Huntington's disease include depression, irritability, mood swings, deficits in memory and concentration, dementia, difficulty in swallowing, jerky movements, and loss of coordination.
Biographical Note for huntington's disease
George (1850–1916), American neurologist. Huntington was a family doctor who published only one medical document, his description of chronic hereditary chorea. His description of 1872, although not the first, is noted for its detailed recounting of the symptoms, especially the regression that eventually results in dementia. The earliest known description of this type of chorea is by Charles O. Waters (1816–1892), published in 1842 in a work by the American physiologist Robley Dunglison (1798–1869).
