1.2 Apply Your Knowledge

1. Narcolepsy is sometimes described as breaking down the lines that separate different realms of consciousness. In addition to suddenly falling asleep during a period of wakefulness, describe another way that this blurring of lines reflects itself.

The answer could include the paralysis resulting from sleep paralysis and loss of muscle tone associated with cataplexy. It could also mention hypnagogic hallucinations.

2. Describe similarities and differences between “sleep attacks” and cataplexy.

Both involve sudden onset and usually short duration. Sleep attacks involve loss of conscious awareness while the sufferer remains conscious of their surrounding during cataplexy episodes.
