Narcolepsy is a chronic neurological sleep disorder that affects the brain’s ability to regulate sleep and wake cycles. People with narcolepsy often experience excessive daytime sleepiness and may suddenly fall asleep during normal activities. Some individuals also have symptoms such as cataplexy (sudden muscle weakness), sleep paralysis, or vivid dream-like hallucinations. Although there is no cure, symptoms can often be managed with lifestyle changes and medical treatment.
Primary Causes of Narcolepsy
Narcolepsy is most often caused by the loss of certain brain cells that produce hypocretin, a chemical crucial for regulating wakefulness and REM sleep. This loss may be linked to autoimmune factors, genetics, or environmental triggers. Understanding these underlying causes helps guide effective management and treatment strategies for patients living with narcolepsy.
