Classification

• There are two forms of Huntington's disease. The most common is adult-onset Huntington's disease. Persons with this form usually develop symptoms in their mid 30s and 40s.

• An early-onset form of Huntington's disease accounts for a small number of cases and begins in childhood or adolescence. Symptoms may resemble those of Parkinson's disease with rigidity, slow movements, and tremor.
