title: Levodopa in Huntingtons chorea.
abstract: Sixteen patients with Huntington's chorea were treated for periods as long as 8 months with levodopa. The condition of none of the patients improved; in fact, there appeared to be an exacerbation of chorea and dementia in addition to undesirable behavioural changes. Therefore, future use of levodopa in these patients is not warranted. The postulated association of low homovanillic acid values in cerebrospinal fluid and favourable response to levodopa therapy was not borne out.
