Prevalence of Sleep Disorders

Studies indicate that a significant portion of the population, ranging from 30% to 50%, will experience a sleep disorder at some point during their lifetime. The exact percentage can vary depending on the specific population and disorder being examined (Bixler, Kales, Soldatos, Kaels, & Healey, 1979; Hossain & Shapiro, 2002; Ohayon, 1997, 2002; Ohayon & Roth, 2002).
