WebHuntington’s disease (HD) is a rare, hereditary, degenerative disorder of the brain that was first described by George Huntington in 1872. Symptoms include motor (movement), behavioural (for example mood) and cognitive (for example understanding) disturbances, which in the majority of cases appear in mid-adult life.
