Classification and Description of Sleep Disorders

Extrinsic sleep disorders

These disorders are those that originate outside the body. These can be caused by environmental or behavioral factors.

1. Inadequate sleep hygiene

People with this disorder have habits that aren't compatible with good sleep or maximum daytime alertness. Caffeine or other drugs near bedtime, or stressful activities before bed, are common problems of sleep hygiene.

2. Environmental sleep disorder

This is a complaint of insomnia due to heat, cold, noise, light, or some other condition in the sleep environment. The patient's own sensitivity to the stimulus is usually more important than the level of the stimulus itself. Sensitivity usually increases toward morning, when sleep debt is low.

3. Altitude insomnia

This problem occurs when people sleep at high altitudes and are not accustomed to low air pressure and lower than normal oxygen levels. It is usually accompanied by fatigue, headache, and loss of appetite.

4. Adjustment sleep disorder

This is a transient insomnia caused by a temporary stressful event. The insomnia appears at the same time as an unusual stressful event, and go away after the event is over.

5. Insufficient sleep syndrome

Experience of someone who persistently fails to get enough sleep to stay normally alert when awake.

6. Limit-setting sleep disorder

This is usually found in children. Limit-setting sleep disorder occurs when someone stalls or refuses to go to bed. When an absolute bedtime is set and met, then the child falls asleep quickly. When limits (bedtimes) are not set and enforced, or enforced only sporadically, a child's sleep will be delayed, and total sleep may not be enough to meet his or her sleep needs.

7. Sleep-onset association disorder

A disorder usually associated with childhood. Here, the individual is unable to sleep unless certain conditions are met such as: the light is on, the window is open, the presence of a favorite blanket, etc. When the conditions are met, the child can sleep easily.

8. Food allergy insomnia

Food intolerance, such as lactose intolerance - a lack of enzymes to easily digest milk, that leads to discomfort and difficulty sleeping.

9. Nocturnal eating (drinking) syndrome

Characterized by repeated awakenings, with an inability to return to sleep without eating or drinking. This is usually a disorder of childhood, but adults can also become conditioned to this behavior. Once learned, this leads to repeated awakenings and reinforcement of the pattern.

10. Hypnotic dependent sleep disorder

Inability to sleep as a result of the tolerance to or withdrawal from a drug used as a sleep inducer. Examples such medications include members of the benzodiazepine group.

11. Stimulant dependent sleep disorder

Insomnia resulting from dependence on or withdrawal from stimulant drugs such as amphetamines, cocaine, caffeine, or asthma medications.

12. Alcohol-dependent sleep disorder

People with this problem depend on alcohol to get to sleep at night. This usually leads to dependence and tolerance-people need more and more alcohol to get to sleep. They also tend to wake up in the middle of the night as the alcohol wears off. (The patient must have used alcohol to help them get to sleep for at least 30 days for positive diagnosis in this case.)

13. Toxin induced sleep disorder

A sleep problem caused by the ingestion of poisonous toxins or heavy metals. Usually found in people who work around toxic substances, or in children who ingest lead paint or other toxic compounds around the house.
