Characterized by difficulty with sleep initiation and/or maintenance, and final awakenings that occur earlier than the established wakeup time.
Patients complain duration of sleep is short or that sleep feels broken, less refreshing, or insufficiently deep, or that the pattern of sleep has changed for worse.
Complains of sleep occur in many psychiatric disorders, including depression, generalized anxiety, panic, and phobia, etc.
Early insomnia or difficulty in getting sleep, occurs in normal people who are aroused through anxiety or excitement. Their thoughts tend to dwell on the affect-laden experiences of the immediate past and also to rehearse ways of dealing with problems. This makes them experience fatigue.
Late insomnia or early morning awakening is characteristic of the depressive phase of affective disorders. In depression, there is a marked change in sleep rhythm from the normal pattern for that person.
