Insomnia most commonly presents comorbidly in association with medical and psychiatric disorders. Comorbid insomnia, however, remains under treated in the majority of patients. Concerns about drug interactions, adverse events, and dependence as well as the assumption that treating the insomnia as a secondary presentation that will resolve when the primary condition improves are all factors that contribute to the under treatment of comorbid insomnia. This article presents the growing research evidence that highlights the benefits and importance of targeting the insomnia that presents comorbidly with medical and psychiatric conditions utilizing the nonpharmacological and effective treatment of cognitive behavior therapy.
