Question

Quizplus · Accepted Answer

The sudden paralysis while remaining conscious is a classic symptom of cataplexy, a condition commonly associated with narcolepsy. REM without atonia is also a sleep disorder, but it does not present with sudden paralysis. Somnambulism (sleepwalking) and sleep attacks are also sleep disorders, but they do not involve paralysis. Situational insomnia refers to occasional difficulty sleeping due to stressful or unfamiliar situations, and is not related to sudden paralysis.
