Neuroendocrine evidence of normal hypothalamus-pituitary dopaminergic function in Huntington's disease.
OBJECTIVES: In addition to neuronal loss in striatum and cerebral cortex that characterizes Huntington's disease (HD), hypothalamic atrophy has also been found only in certain areas, probably not including dopaminergic functions.
METHODS: We assessed the reactivity of the hypothalamus-pituitary dopaminergic syste.....
