Thirteen drug-free and not severely affected patients with idiopathic Parkinson's disease underwent an insulin-hypoglycaemia test, a TRH test and a levodopa test. The responses of growth hormone, prolactin, cortisol and thyrotropin were measured, and retested under stable therapy with levodopa and b

β¦ Synopsis
Plasma profiles of prolactin, growth hormone, adrenocorticotropic hormone (ACTH) and cortisol were evaluated in a group of untreated patients with idiopathic Parkinson's disease and a group of healthy age-matched controls. Plasma integrated concentrations of all hormones except prolactin were significantly lower in the patients as compared with the controls; however, prolactin nocturnal peak concentration was significantly elevated in the patients; nocturnal growth hormone levels were significantly reduced in the Parkinson group; ACTH and cortisol plasma concentrations were also consistently lower during most of the day in the patients with Parkinson's disease. These data confirm the presence of a hypothalamic disturbance in patients with idiopathic Parkinson's disease, which can affect pituitary function.

8 mg of naloxone were administered IV to 14 normal volunteers in a placebo-controlled, double-blind experiment. Plasma levels of beta-endorphin, cortisol, prolactin, growth hormone, HVA and MHPG were determined before and 45 min after administration. Naloxone elicited significant increases in cortis
