Abstract

Discusses various views on the phenomenon of morbid sleepiness, and its two forms - a continuous drowsiness extending over a prolonged period of time and of varying degrees of intensity, and sleep attacks varying in depth from drowsiness to complete unconsciousness and in duration from a few minutes to many hours. Reports various cases, demonstrating differences between the lethargic or trance state and normal sleep. The diagnostic features of hysterical and epileptic pseudonarcolepsy have been given along with the cause for these peculiar attacks. Claparede reviewed these theories for the cause of sleep: (1) cerebral anemia and hyperemia, (2) lymphatic hypertension, (3) interruption of conductivity in various parts of the brain, (4) the histologic theories, (5) the inhibition of intellect, default in excitations, and (6) the supra-physiologic hypothesis. Objected to all of them as they were the consequence rather than a cause of sleep. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
