Narcolepsy is a neurological disorder that involves dysfunctional sleep-wake cycles. Signs and symptoms of narcolepsy may include the following:
- Excessive daytime sleepiness – an overwhelming desire to fall asleep throughout the day that disrupts a person’s ability to function. This occurs despite having had a good night’s sleep. EDS is typically the first indicator of a problem.
- Obesity – individuals with narcolepsy often report sudden weight gain
- Disrupted nocturnal sleep – difficulty falling asleep at night due to periodic leg movements, insomnia, vivid dreams, and/or talking during sleep
