The Kleine-Levine syndrome--a variant?
A case of Kleine-Levin syndrome in an older man is described, with a review of the literature. An important point is emphasized in our case in which the patient reacted unfavorably to Ritalin, becoming sexually aroused, although his hypersomnia improved. A possibly different mechanism in hypersomnia and hypersexuality is speculated.
