[Characteristics of the night sleep of patients with neuroses and a subjectively good and bad sleep].

Polysomnographic analysis of the night sleep in neurotic patients with subjectively good (SGS, 12 patients) and bad (SBS, 18 patients) sleep showed that a certain degree of sleep impairment is an obligatory sign of neurosis, though night sleep characteristics changed in SGS to a greater extent than in SBS, irrespective of clinical equivalence and high anxiousness in both groups. Discriminative analysis provided a reliable differentiation between groups of SGS, SBS and normal with SGS occupying an intermediate position in sleep characteristics. The conclusion is that not only anxiousness, but also the brain somnifacient systems' resistance against challenging factors determine the sleep structure. Of no lesser importance are the general peculiarities of night sleep organization. The role of the 2 stages in sleep regulation are discussed.
