[State of cerebral functions in the persistent lactorrhea-amenorrhea syndrome].

A complex investigation of the brain functions of patients with the idiopathic persisting lactorrhea-amenorrhea syndrome (PLAS) revealed a series of nonspecific changes. Insufficiency of the activating systems was shown according to the EEG data. Anxious depression was also seen. The examination of the vegetative nervous system during relaxation and exercises is indicative of insufficient activity of its symptomatic region. Thereafter, specific neurosecretory deficit in the tuberous infundibular system and disorder of the brain activity, probably resultant of dopamine deficiency are seen in patients with PLAS.
