![]() ![]() People with narcolepsy may also have a "sleep attack" at a very unusual and sometimes dangerous time (while in the middle of a conversation or driving a car). They tend to fall asleep not only in situations in which many normal people feel sleepy (after meals or during a dull lecture), but also when most people would remain awake (while watching a movie or writing a letter). People with narcolepsy often report feeling easily tired or tired all the time. Excessive daytime sleepiness (EDS)ĮDS is usually the first symptom of narcolepsy. In some cases, excessive daytime sleepiness is the only symptom. The four most common symptoms are: excessive daytime sleepiness, cataplexy, sleep paralysis and hypnagogic hallucinations. ![]() Narcolepsy symptoms can appear all at once or they can develop slowly over many years. Some researchers have suggested that a set of genes combines with additional unknown factors in a person's life to cause narcolepsy. ![]() Narcolepsy often runs in families, but many people with narcolepsy do not have relatives who are affected. Narcolepsy is not caused by psychiatric or psychological problems. In narcolepsy the lack of muscle tone and the dream experiences occur at inappropriate times. Cataplexy, sleep paralysis, and hypnagogic hallucinations are similar to the loss of muscle tone that accompanies normal dreaming in a stage of sleep called REM. However, narcolepsy appears to be a disorder of the part of the central nervous system that controls sleep and wakefulness. What causes narcolepsy? Although narcolepsy has been thoroughly studied, the exact cause is not known. Although no "cure" for narcolepsy has been found, most children with narcolepsy can lead nearly normal lives if properly treated. While narcolepsy is relatively uncommon, its impact on a child's life can be dramatic and, if not recognized, disabling. Polysomnography can detect breathing disorders (such as obstructive sleep apnea), seizure disorders, narcolepsy, periodic limb movement disorder, and unusual movements and behaviors during sleep (parasomnias).Narcolepsy is a sleep disorder that causes symptoms such as excessive daytime sleepiness and, in some cases, "sleep attacks." These "attacks" cause people with narcolepsy to fall asleep at very unusual and sometimes dangerous times (while in the middle of a conversation or driving a car). A painless clip is attached to a finger or an ear to record oxygen levels in the blood.

This record, the electrocardiogram (also known as an ECG). ![]() Electrodes are also attached to other areas of the body to record heart rate ( electrocardiography Electrocardiography Electrocardiography (ECG) is a quick, simple, painless procedure in which the heart’s electrical impulses are amplified and recorded. The recordings help provide doctors with information about sleep stages. read more, or EEG) as well as eye movements. Electrodes are pasted to the scalp and face to record the brain's electrical activity ( electroencephalography Electroencephalography Diagnostic procedures may be needed to confirm a diagnosis suggested by the medical history and neurologic examination. Polysomnography is usually done in a sleep laboratory, which may be located in a hospital, clinic, hotel room, or other facility that is equipped with a bed, bathroom, and monitoring equipment. ![]()
