How common are sleep disorders?
Sleep disorders affect approximately 20% of the American population, and sleep-related problems affect 50-70 million Americans of all ages.4 However, 50% or more of patients remain undiagnosed and therefore do not receive needed treatment.4 For instances it is estimated that 60-64% of chronic insomnia cases are not recognized by primary care physicians.5 Of the various types of Sleep Disorders, insomnia is more common with about 30% of adults experience transient insomnia (lasting a month or less) and 15% of adults experience chronic insomnia (lasting 4 or more weeks).5 Sleep-related problems have the same clinical relevance in women as men 3, but some sleep problems are more common in women (e.g., Nightmare Disorder) and some are more common in men (e.g. sleep apnea).
