Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness, making individuals extremely drowsy during the day. People with narcolepsy struggle to stay awake for extended periods and may suddenly fall asleep at inappropriate times, significantly disrupting their daily routine.
Some individuals with narcolepsy experience a sudden loss of muscle tone, known as cataplexy, which can be triggered by intense emotions, particularly laughter. Narcolepsy is classified into two types; type 1 narcolepsy involves cataplexy, while type 2 narcolepsy does not exhibit this symptom.
Unfortunately, narcolepsy is a lifelong condition without a cure. However, symptom management can be achieved through medications and lifestyle changes. Support from family, friends, employers, and teachers can significantly help individuals cope with the disorder.
The symptoms of narcolepsy often persist throughout a person’s life, with daytime sleepiness being a prominent feature. Individuals with narcolepsy may experience:
Additionally, people with narcolepsy may experience other sleep disorders such as obstructive sleep apnea, REM sleep behavior disorder, or insomnia.
The exact cause of narcolepsy remains unknown, but research suggests that type 1 narcolepsy is associated with low levels of hypocretin (orexin), a brain chemical that regulates wakefulness and REM sleep. The loss of hypocretin-producing cells in the brain may result from an autoimmune reaction, where the body’s immune system attacks its own cells.
Genetics may also play a role in narcolepsy, although the risk of inheriting the disorder from a parent is low. Furthermore, exposure to certain viruses, such as the swine flu (H1N1 flu) or a specific H1N1 vaccine, has been linked to narcolepsy in some cases.
Typically, narcolepsy starts between the ages of 10 and 30, and individuals with a family history of the condition have an increased risk of developing narcolepsy.
Narcolepsy can give rise to various complications, including:
