Which condition involves repeated pauses in breathing during sleep?

• A. Insomnia
• B. Narcolepsy
• C. Sleepwalking
• D. Sleep Apnea

Answer: (D)

Repeated pauses in breathing during sleep point to a sleep-disordered breathing condition. In sleep apnea, the airway repeatedly narrows or collapses as you sleep, causing brief stops (apneas) or shallow breaths (hypopneas). The brain senses the drop in oxygen and briefly wakes you to restart breathing, which fragments sleep and leads to daytime tiredness, loud snoring, and other symptoms. The most common form, obstructive sleep apnea, happens because throat muscles relax and block the airway during sleep. This is different from insomnia, which is trouble falling or staying asleep without breathing interruptions; narcolepsy involves sudden, uncontrollable sleep attacks and often other symptoms like cataplexy; and sleepwalking happens during deep non-REM sleep with complex behaviors while still partially asleep, not driven by breathing pauses.
