This is a very rare disorder, affecting mostly adolescent males (70% of sufferers are adolescent males). It is defined by recurring, but reversible, periods of excessive sleep, lasting up to 20 hours a day! The onset of symptoms may be abrupt and are usually associated with flu-like symptoms (I Arnulf, 2008). Depression may occur as a consequence of the disorder and there is no definitive treatment- again, stimulants such as amphetamines are used to treat the sleepiness but will not improve cognitive abnormalities.
