Narcolepsy is a neurological disorder characterized by excessive daytime sleepiness, sudden loss of muscle tone resulting in weak or limp muscles (known as cataplexy), and sometimes hallucinations and sleep paralysis. This aligns with Karen's symptoms of suddenly falling asleep in the middle of the day. Sleep apnea involves breathing difficulties during sleep, while sleep-wake cycle disorder and insomnia both involve difficulty falling asleep or staying awake as desired, which does not align with Karen's sudden sleep attacks.
