Researchers want to understand how severe obstructive sleep apnea—a condition where breathing repeatedly stops during sleep—affects the brain's ability to process sounds and stay focused during the day. This observational study will compare adults with severe sleep apnea to healthy adults matched by age and gender, using hearing tests and brain activity measurements to see if sleep apnea causes early changes in how the brain handles sound and attention.
Sleep apnea is known to affect the brain, but doctors don't fully understand how it specifically damages the hearing and attention systems. This research could help identify warning signs of these problems earlier, before symptoms become obvious, so people can get treatment sooner.

If you join, you'll complete hearing tests and a brief thinking assessment. You'll also wear an EEG cap (which measures brain activity) for about 1.5 to 2 hours while sitting in a quiet room listening to sounds—sometimes you'll just relax, and sometimes you'll press a button when you hear rare tones. If you're in the sleep apnea group, you'll also have one overnight sleep study. You'll be compensated at ¥75 per hour for your time.
