- Sleep paralysis: Temporary inability to move or speak upon waking or falling asleep.
- Hypnagogic hallucinations: Vivid, dream-like experiences that occur while falling asleep.
- Automatic behaviors: Unconscious, repetitive actions performed while in a state of drowsiness.

- Type 2 narcolepsy: Characterized by EDS without cataplexy.
Questions Often Asked: Which Of The Following Statements Is True Of Narcolepsy
What are the key characteristics of narcolepsy?
Narcolepsy is characterized by excessive daytime sleepiness (EDS), cataplexy (sudden loss of muscle tone triggered by emotions), sleep paralysis (temporary inability to move or speak upon waking or falling asleep), and hypnagogic/hypnopompic hallucinations (vivid, dream-like experiences during the transition to or from sleep).
What causes narcolepsy?
Narcolepsy is primarily caused by a deficiency of hypocretin (orexin), a neurotransmitter that regulates sleep-wake cycles. This deficiency can be genetic or acquired through factors such as head injuries or infections.
How is narcolepsy diagnosed?
Narcolepsy is diagnosed based on a combination of symptoms and specialized sleep studies, such as polysomnography (PSG) and multiple sleep latency test (MSLT), which assess sleep patterns and measure daytime sleepiness.
