what is Huntington disease ? it is shortly called HD and it is a genetic disorder of the central nervous system with symptoms usually appearing in adults within the third or fourth decade of life, although symptoms can occur in individuals younger or older than this.
Within the same family, the symptoms vary both in their rate of progression and in the age of onset. Symptoms may include involuntary movements and loss of motor control. In addition, personality changes may occur, with loss of memory and decreased mental capacity. Symptoms in individuals, as well as confirmation of diagnosis in other family members, are used to determine the diagnosis.
Huntington disease is inherited as an autosomal dominant condition.
