Narcolepsy is a very rare sleeping disorder which presents with an inability to keep awake during daytime. The disorder is also characterized by sudden attacks of sleep over which the individual has no control. Narcolepsy varies in severity and is often mistaken for other medical disorders like seizures, depression, fainting spells, excess fatigue or other sleep related disorders. Unfortunately narcolepsy has no cure but the disorder does stabilize in the later years of life. In the USA it is estimated that about 1 in 2000 people may have narcolepsy. Narcolepsy is more common in males and tends to occur in all races and cultures.
Excessive daytime sleepiness is the universal complaint. Most individuals complain that the desire to sleep is sudden and uncontrollable. Besides excess sleep, one may also experience decreased alertness and an inability to concentrate. Other features of narcolepsy include extreme muscle weakness and hallucinations or vivid dreams while semi awake. People with narcolepsy may also act out their dreams and during sleep one may notice gross body movements like crying, flailing arms, screaming, or kicking.
No one knows why narcolepsy develops and it has been attributed to genetics, infection(s) or some type of brain damage.
The tragic thing about narcolepsy is that most people are not aware of the disorder and often distinguish these individuals as lazy, hypochondriacs, malingerers, stupid or aloof. Most individuals with narcolepsy have poor performance both at school and at work. The disorder can also affect personal relationships, lead to loss of libido, and/or impotence. For example, many individuals fall asleep during sex. There is no cure for this agonizing disorder but medications and lifestyle changes may help.
Drugs which stimulate the brain have widely been used to treat narcolepsy. Modafinil, Ritalin and anti depressants have been used to treat patients with narcolepsy. Although these medications are effective, they have potent side effects, are addictive and can lead to withdrawal symptoms when abruptly stopped.
