Which term describes misperception of sleep duration and quality?

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

Answer: (A)

Paradoxical insomnia is the phenomenon where a person’s subjective experience of sleep doesn’t match objective sleep data. They feel they didn’t sleep well or slept only briefly, yet objective measures show normal or near-normal sleep duration and architecture. This mismatch between what the person perceives and what is actually recorded is the defining feature. It can occur with heightened arousal around sleep, causing distress and a belief that sleep was poor even when sleep tests look normal. In contrast, circadian rhythm disorders involve a misalignment of the internal clock with the environment and affect when someone sleeps, not necessarily how much they sleep or the perceived quality. Idiopathic hypersomnia centers on excessive daytime sleepiness and long nocturnal sleep with difficulty waking, not misperception of sleep duration. Behavioral insomnia stems from learned sleep behaviors and patterns rather than a dissociation between subjective sleep and objective measurements.
