• Huntington's chorea (HC) was studied in 14 untreated patients, in six patients receiving long-term neuroleptic treatment, and in four patients after drug withdrawal. Our results showed that patients with HC may be divided into three groups, otherwise clinically indistinguishable, on the basis of growth hormone responsiveness to dopaminergic stimuli. The existence of subpopulations of patients with HC must be considered in further studies on these subjects.
