Help for sleep problems
For those who suffer from sleep disorders, help is available from many sources.
Sleep problems may be caused by or be the result of disorders in various systems of the body. Obstructive sleep apnea, for example, is a respiratory disorder while narcolepsy is a neurological disorder.
Sleep problems can be treated or managed by different medical specialties. For example, pulmonary medicine will offer help to people who suffer from sleep apnea, and neurology will provide treatment for narcolepsy.
However, other medical specialties also offer treatment for sleep disorders. Many rehabilitation facilities and anesthesiology departments sponsor comprehensive sleep disorder programs, as do mental health centers. The American Board of Sleep Medicine establishes standards and certification for physicians and scientists who wish to become certified in sleep medicine.
Talk with your doctor about which sleep disorder program is right for you.
