1. The frequent occurrence of hypothalamo-pituitary dysfunction in patients with eating disorders as well as prior reports that nutritional and endocrine status influence pituitary morphology, led us to hypothesize that pituitary size and shape may be alte ...

In this pilot study, a prolonged (interictal) delirium was induced by electroconvulsive therapy (ECT) in seven out of seven depressed patients with Parkinson's disease. This occurrence of delirium appears much higher than what has been reported in other pa ...
