Chronic insomnia increases in frequency with age and is more common in the elderly. This is presumed to be the result of greater psychosocial stressors, losses, and medical illnesses. Epidemiologic data indicate that the prevalence of chronic insomnia increases from 25% in the adult population to nearly 50% in the elderly population. [54]
