Excerpt

Disturbances of sleep occur at some point in the life of essentially everyone. However, the presence of a clinically significant insomnia disorder requires that the sleep disturbance meet a specific set of criteria: 1) there is a complaint of difficulty falling asleep or staying asleep; 2) this complaint is associated with clinically significant distress and/or daytime functional impairment; 3) these difficulties occur despite an adequate opportunity for sleep; and 4) the sleep disturbance is present for three or more nights per week for at least 3 months (American Academy of Sleep Medicine 2014; American Psychiatric Association 2013; Krystal 2007).
