Integrating Modern Concepts of Insomnia and its Contemporary Treatment into Primary Care

Abstract

Insomnia affects one-third of the adult population. Ten percent of adults surveyed in America consider it a serious problem. Chronic insomnia is associated with poor quality of life and the potential for various psychiatric and medical conditions, notably depression and cardiovascular disease. Since most patients with insomnia are unlikely to disclose obvious sleeping difficulties, the first step in diagnosing and managing patients is having a high index of suspicion in patients with specific complaints, comorbidities, and risk factors. This is followed by a complete evaluation of the patient's medical and physical history to determine if the insomnia is primary or comorbid with another disease. The management of insomnia should consider the extent of impairment associated with the disorder, as well as duration, causes, and comorbidities. In some cases, referral to a specialist is warranted. Recently, there have been new definitions of insomnia proposed; elucidation of the role of orexin-mediated hyperarousal brain neural pathway in the sleep-wake cycle; and new drugs available that target this system. Thus, a review and update for today's primary care physician is warranted.

“…It should be treated by addressing the underlying causative factors widely or through a referral to a sleep specialist. 68 Chronic insomnia can be best treated by using non-pharmacological techniques, such as cognitive behavioral the rapies or reviewing sleep hygiene.
