Document Summary
There are 78 different types of sleep disorders. Insomnia refers to chronic problems in getting adequate sleep. It occurs in three basic patterns: (1) difficulty in falling asleep initially, (2) difficultly in remaining asleep, and (3) persistent early-morning awakening. Insomniacs have to endure the agony of watching their precious sleep time tick away as they toss and turn in restless frustration. Insomnia is associated with daytime fatigue, impaired functioning, and elevated risk of accidents, reduced productivity, absenteeism at work, depression, anxiety, substance abuse, hypertension, and increased health problems. Some people suffer from pseudo-insomnia which means that they just think they are getting an inadequate amount of sleep. Some people are predisposed to insomnia because they have a higher level of physiological arousal than the average person. The most common approach in the medical treatment of insomnia is the two drugs: benzodiazepine sedatives, which relieve anxiety, and nonbenzodiazepine sedatives which were primarily designed for sleep problems.
