Cognitive and behavioral treatment options for insomnia.

Insomnia is a costly disorder that affects a significant number of people. In many cases, insomnia is comorbid with other illnesses, which complicates its diagnosis and treatment. Most often it is treated with medication; however, patients are not always safe using hypnotics, and medication does not attack the source of the disorder. Cognitive behavioral therapies are better for long-term treatment because they address factors causing or perpetuating insomnia, as opposed to treatments that focus on symptoms.
