Prevalence and correlates of sleep disorder symptoms in psychiatric disorders
Sleep disturbances are commonly observed in the general population and in individuals with psychiatric illnesses. In fact, the highest prevalence of insomnia is observed in psychiatric patients (Ford and Kamerow, 1989). Those suffering from sleep disorders often present with symptoms of discontent with regard to quality of sleep, timing and sleep quantity (APA, 2013) and these symptoms have adverse impact on function and quality of life (McCall et al., 2000; Szentkiralyi et al., 2009). Epi demiological data from the Western populations suggest that the prevalence of various sleep disorders in the general population ranges from 0.047% to 50.5%.
