Huntington's disease is an autosomal dominant neurodegenerative disorder.
Often presents in mid-life but may appear at any age.
Clinical manifestations include chorea, cognitive decline, loss of coordination, and personality change.
Depression and suicide may be comorbid events.
In the absence of available effective treatment, many at-risk individuals forgo predictive genetic testing.
Huntington's disease is a slowly progressive, neurodegenerative disorder characterised by chorea, incoordination, cognitive decline, personality changes, and psychiatric symptoms, culminating in immobility, mutism, and inanition. It is an autosomal dominant, trinucleotide repeat disorder that affects men and women equally. It characteristically appears in mid-adult life but can occur at any age. Treatment for depression, and to some degree behavioural problems and chorea, is possible. There are no disease-modifying therapies.
