Huntington's disease is caused by an inherited defect in a single gene. Huntington's disease is an autosomal dominant disorder, which means that a person needs only one copy of the defective gene to develop the disorder.
Huntington's disease usually causes movement, cognitive and psychiatric disorders with a wide spectrum of signs and symptoms. Which symptoms appear first varies greatly among affected people. The earliest symptoms are problems that have to do with mood or cognition. You have many changes and disorders that have to do with the Huntington's disease like physical changes, behavioral changes, movement disorders, cognitive disorders, and psychiatric disorders.
