Narcolepsy Explained
Chronic neurological disorder affecting sleep-wake regulation
Narcolepsy is a chronic neurological disorder that affects the brain's ability to regulate sleep-wake cycles. People with narcolepsy experience overwhelming daytime drowsiness and sudden, uncontrollable sleep attacks. The condition is caused by a deficiency of hypocretin (orexin), a neurotransmitter that regulates wakefulness.
Common Symptoms
Excessive daytime sleepiness
Sudden sleep attacks
Cataplexy (sudden muscle weakness)
Sleep paralysis
Hypnagogic hallucinations
Disrupted nighttime sleep
How Treatment Can Help
Modafinil is FDA-approved for narcolepsy and works by promoting wakefulness and reducing excessive daytime sleepiness. It helps patients maintain alertness during the day.
Modafinil has risks and side effects. Review its safety information.
When to Seek Evaluation
Immediate evaluation is recommended if you experience sudden sleep attacks, cataplexy, or overwhelming daytime sleepiness that interferes with safety and daily activities.
