Summaries for Short Sleep, Familial Natural, 1

OMIM : 56 In a review of various classification schemes for sleep disorders, Thorpy (1990) listed 'short sleeper' under the broad category of 'disorders of initiating and maintaining sleep' (DIMS); however, the short sleeper phenotype or trait is not considered a sleep disorder. Individuals with this trait require less sleep in any 24-hour period than is typical for their age group. (612975)
