Narcolepsy is a chronic neurological disorder that disrupts the brain’s ability to control sleep-wake cycles. The disorder is likely caused by a genetic predisposition and abnormal neurotransmitter functioning and sensitivity. Narcolepsy is relatively common and affects 1 in 2,000 people of both genders. Individuals with narcolepsy usually feel rested after waking, but later experience extreme and unpredictable sleepiness throughout much of the day. Many individuals with narcolepsy also experience uneven and interrupted sleep that can involve waking up frequently during the night.
While not life-threatening, narcolepsy can greatly affect daily activities and make day-to-day life a lot more difficult. Those with narcolepsy may unwillingly fall asleep, making it harder to get through typical errands, events, and work.
The most common symptoms are excessive daytime sleepiness, cataplexy, sleep paralysis, and hallucinations. People with the narcolepsy can experience some or all of these symptoms to different degrees and frequencies. Though all have excessive daytime sleepiness (EDS), only 1/4 of individuals will experience all other symptoms during the course of their illness.
Everyone who has narcolepsy will experience EDS, and it is often the most obvious symptom of the disorder. EDS is characterized by persistent and unavoidable sleepiness, regardless of how much sleep a person gets. This overwhelming sense of sleepiness feels like a “sleep attack” that hits suddenly and unexpectedly. Circumstances that would make anyone sleepy, such as dark rooms, jet-lag, or heavy meals, make a person with narcolepsy a lot more tired than average. In between these sleep attacks, those affected have regular levels of alertness before.
Cataplexy is a sudden and uncontrollable lack of muscle strength and paralysis. A person experiences cataplexy while awake, and it is often triggered by sudden, strong emotions. Unlike EDS, cataplexy may only appear weeks or even years after an onset of EDS. Individuals may only have a couple attacks their entire lifetime while others may experience them daily. Attacks range from mild to severe and can involve a momentary sense of slight weakness or a total body collapse. While these attacks may seem scary, they only last a few minutes. They are not dangerous as long as the person suffering from cataplexy finds a safe place to have their episode.
Sleep paralysis is similar to cataplexy but occurs at the edges of sleep. The symptom is characterized by the temporary inability to move or speak while falling asleep or waking up. Each episode usually lasts only a few seconds or minutes and resembles REM-induced inhibitions of voluntary muscle activity.
Some people with the disorder experience vivid visual or auditory sensations when falling asleep or waking up. More typically the hallucinations are primarily visual, but any of the other senses can be involved.
