Narcolepsy
Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness, sudden loss of muscle strength (cataplexy), sleep paralysis, and hallucinations. People with narcolepsy may fall asleep involuntarily during normal activities due to a blurred boundary between wakefulness and sleep. Cataplexy, a symptom of narcolepsy, involves muscle paralysis similar to that of REM sleep during waking hours. This disorder is often caused by a deficiency of hypocretin, a chemical in the brain that regulates wakefulness and sleep cycles. While there is no cure for narcolepsy, medications, and behavioral treatments can help manage symptoms. Diagnosis involves a physical exam, medical history, and sleep studies. Treatment typically involves a combination of medications and lifestyle adjustments. Support groups and educational networks can provide valuable resources for individuals living with narcolepsy.
