Sleep state misperception is also known as which term?

• A. Circadian rhythm disorder
• B. Idiopathic hypersomnia
• C. Paradoxical insomnia
• D. Behavioral insomnia

Answer: (C)

Sleep state misperception occurs when a person believes they slept little or not at all, yet objective sleep testing shows they actually slept for a normal or near-normal amount. The term used for this phenomenon is paradoxical insomnia. Think of it this way: someone might report lying awake for hours and feeling they got almost no sleep, but polysomnography or actigraphy reveals normal total sleep time and typical sleep stages. That mismatch between perception and reality is the hallmark of paradoxical insomnia. The other options don’t capture this specific mismatch. Circadian rhythm disorders involve trouble with the timing of sleep rather than a persistent underestimation of sleep duration. Idiopathic hypersomnia describes excessive daytime sleepiness with long nighttime sleep, not a misperception of how much sleep occurred. Behavioral insomnia stems from learned or conditioned behaviors and poor sleep habits, not from a disconnect between perceived and actual sleep.
