Which condition is characterized by breathing pauses during sleep due to airway obstruction?

• A. Obstructive Sleep Apnea (OSA)
• B. Central Sleep Apnea
• C. Periodic Limb Movement Disorder
• D. Insomnia

Answer: (A)

Breathing pauses during sleep caused by airway obstruction point to obstructive sleep apnea. In this condition, the muscles of the throat relax during sleep, causing the upper airway to narrow or collapse. As a result, airflow stops intermittently even though the person continues to attempt to breathe, often leading to brief awakenings to reopen the airway. This pattern commonly produces loud snoring and daytime sleepiness, and it is more prevalent in older adults and in individuals with factors like obesity or certain craniofacial structures. By contrast, central sleep apnea involves pauses in breathing due to the brain not sending the proper signals to breathe, not an airway blockage. Periodic limb movement disorder features leg movements that disrupt sleep, not breathing pauses. Insomnia describes difficulty sleeping rather than a breathing-related sleep disruption. Treatments focus on keeping the airway open, with approaches such as CPAP, weight management, positional therapy, or oral appliances.
