Genetics

Huntington's disease (HD) is a genetic condition of the brain. Symptoms usually begin to occur in adults between 30 and 50 years of age, although symptoms can occur in people who are younger or older as well. Even within the same family, the age of onset and symptoms may vary.

The diagnosis of HD in an individual or family member can have an immediate impact on people's perceptions of themselves, on their day-to-day lives, and on their plans for the future.  Although for some people the impact may be delayed, the challenges are no less significant. The process of adjusting to these life changes after diagnosis is different for everyone.

Each child of a parent with HD has a 50% chance of inheriting the disease.
