[Current concepts of the hypothalamic syndrome].

Current views on the hypothalamic syndrome are presented as derived from the review of recent advances in neuroendocrinology and autonomic function studies, and the authors' personal experience as well. The data on etiology, pathogenic mechanisms of hypothalamic disorders are presented. Diagnostic criteria for hypothalamic syndrome are given and results of the combined psychophysiological investigation of its major forms are summarized. The data suggest the leading role of constitutional-acquired neurotransmitter deficiency in the hypothalamic syndrome. The organic defect had a residual character with no topical correlates, was relatively stable and of no substantial influence on the shaping of clinical signs and their course.
