Abstract
AN UNUSUAL CASE OF TOTAL AND IRREDUCIBLE INSOMNIA IN A PARKINSONIAN PATIENT AFTER BILATERAL STEREOTACTIC THALAMOTOMY IS REPORTED. DURING 96 HR. OF TOTAL INSOMNIA THE PATIENT'S BEHAVIOR DIFFERED FROM THAT OF PERSONS EXPERIMENTALLY DEPRIVED OF SLEEP BY SHOWING NO CAPACITY FOR SLEEPING; HE WAS FULLY ALERT AND WELL ORIENTATED. SUBSEQUENTLY THE S PRESENTED INVERSION OF THE SLEEP-WAKEFULNESS RHYTHM, WHICH PROGRESSIVELY BECAME MORE REGULAR. A POLYGRAPHIC RECORDING DURING THE RECOVERY STAGE SHOWED ABNORMAL SLEEP: PHASES 1 AND 3 WERE MARKEDLY PROLONGED, PHASE 2 WAS POORLY REPRESENTED, AND PHASE 4 WAS MISSING ALTOGETHER. THE STEREOTACTIC LESIONS, BILATERALLY DELIVERED TO THE THALAMUS, INVOLVED, BESIDES THE VENTRALIS LATERALIS, THE VENTRALIS INTERMEDIUS, PARTIALLY THE VENTRALIS POSTERIOR, AND THE CENTRO-MEDIANUS, OTHER NUCLEI OF THE SO-CALLED NONSPECIFIC PROJECTION SYSTEM. THIS CASE MAY INDICATE THAT THE THALAMUS, ESPECIALLY THE NONSPECIFIC THALAMUS, IS INVOLVED IN THE DETERMINATION OF SLEEP INDUCTION. (22 REF.) ((c) 1997 APA/PsycINFO, all rights reserved)
