Huntington's disease

Also called Huntington's chorea

Huntington's disease is an inherited condition that stops parts of the brain working properly over time. It is caused by a faulty gene, and each child of a parent with the gene has a 1 in 2 chance of inheriting it. Symptoms usually start between the ages of 30 and 50 and gradually get worse.
