Insomnia is a clinical diagnosis. Diagnostic studies are indicated principally for the clarification of comorbid disorders.

Before therapy is instituted, most patients are asked to keep a sleep log for 2-4 weeks. This log, in which the patient records bed and wake times, sleep duration, and daytime naps and activities, gives a clearer picture of the degree of sleep disturbance and allows development of a tailored treatment.
