Polysomnography in 3 1 patients with cerebral malformations was performed. In 9 cases, the hormone secretion rhythms during sleep (GH, PRL, LH, FSH and ACTH and/or cortisol) were examined. EEG showed abnormalities in 27 of the 31 pathologic patients. A defect and poor presentation of the sleep spindle was observed in 20 cases. Patients with cerebral malformations appeared to be poor sleepers. The amount and number of wakefulness increased. A decrease in REM sleep period was observed in 19 of the 36 records. 17 of the 31 pathologic patients showed abnormal proportions of time spent in the different stages of sleep with respect to the total sleeping time. 15 of the 31 pathologic patients showed more than one discrepant cycling of sleep parameters. Abnormal hormone secretion was observed in all 9 patients who were examined. The above results show that patients with cerebral malformations have various abnormalities of sleep behaviors, and that polysomnography is useful for studying sleep behavior in patinets with cerebral malformations.
