What is a practical approach to distinguishing primary insomnia from insomnia with comorbid sleep apnea?

• A. Treat insomnia exclusively with sedatives without evaluating OSA
• B. Ignore possible OSA
• C. Evaluate for OSA symptoms, screening, treat OSA to see improvement
• D. Refer to sleep lab first

Answer: (C)

The main idea is to actively screen for sleep apnea when evaluating insomnia so you can see if obstructive sleep apnea is contributing to the sleep problems. Start by looking for symptoms and risk factors of OSA—snoring, witnessed pauses in breathing, gasping or choking at night, daytime sleepiness, morning headaches, obesity, neck circumference, and other health factors. Using quick screening tools (like STOP-BANG or Epworth Sleepiness Scale) helps quantify the risk. If the screening suggests possible OSA, move forward with a formal evaluation and, importantly, consider treating the suspected sleep apnea (for example, with CPAP) and monitoring whether insomnia symptoms improve. Improvement after treating OSA points to the insomnia being driven by the sleep-disordered breathing rather than being primary insomnia. If there’s no improvement, you’d continue exploring primary insomnia or other contributing conditions. This approach avoids masking potential OSA with sedatives and focuses on addressing the underlying cause, while not jumping straight to a sleep-lab referral or assuming insomnia is independent of breathing issues.
