AP PSYCHOLOGY

Detailed explanation-1: -Narcolepsy is a chronic neurological disorder that affects the brain’s ability to control sleep-wake cycles. People with narcolepsy may feel rested after waking, but then feel very sleepy throughout much of the day.

Detailed explanation-2: -Types of narcolepsy Type 1 narcolepsy used to be known as “narcolepsy with cataplexy.” Type 2 used to be called “narcolepsy withoutcataplexy.” In very rare cases, a person may develop another type of narcolepsy known as secondary narcolepsy.

Detailed explanation-3: -Since the discovery of sleep onset REM periods (SOREMPs) in narcoleptic patients, narcolepsy has often been regarded as a disorder of REM sleep generation: REM sleep intrudes in active wake or at sleep onset, resulting in cataplexy, sleep paralysis, or hypnagogic hallucinations.

Detailed explanation-4: -Narcolepsy. Excessive daytime sleepiness (including episodes of irresistible sleepiness) combined with sudden muscle weakness are the hallmark signs of narcolepsy.

Detailed explanation-5: -Cataplexy is a condition that brings on brief bouts of muscle weakness or paralysis. It can happen in people living with the sleep disorder narcolepsy. Some people have an episode of cataplexy just once or twice in their lives.
