Abstract
• Following a recent report that apomorphine hydrochloride alleviates the involuntary movements of Huntington chorea, we have investigated another dopamine receptor agonist, bromocriptine, in this disease. A double-blind crossover study in six patients showed that rather than improving chorea, bromocriptine induced an exacerbation. This finding supports the view that choreatic movements correlate with overactivity in dopaminergic systems.
