Huntington's disease. Definition. Huntington's disease is an inherited disease that causes the progressive breakdown (degeneration) of nerve cells in the brain. Huntington's disease has a broad impact on a person's functional abilities and usually results in movement, thinking (cognitive) and psychiatric disorders.
As the abnormal protein accumulates, it causes pathological changes that lead to the symptoms of Huntingtonâs disease. Huntingtonâs disease is inherited in an autosomal dominant manner. All nucleated cells of the human body contain 46 chromosomes, with 23 derived from each parent.
