yes Narcolepsy is a chronic neurological disorder that affects the brain’s ability to regulate sleep-wake cycles. People with narcolepsy experience excessive daytime sleepiness and sudden, uncontrollable sleep attacks, which can interfere with daily life, work, and social interactions. The exact cause of narcolepsy is not fully understood, but it is believed to be linked to low levels of hypocretin, a neurotransmitter that helps regulate wakefulness.
