This research study is exploring 'brain fog'—difficulty with memory, attention, and concentration—in people with severe obstructive sleep apnea (a condition where breathing repeatedly stops during sleep). The researchers want to compare brain fog symptoms in two groups: people who have been using CPAP therapy (a mask device that keeps airways open during sleep) for at least 3 months, and people who were recently diagnosed but haven't started treatment yet.
Brain fog is a real problem that many sleep apnea patients report experiencing, but researchers haven't thoroughly studied it yet. This study aims to understand whether brain fog is common in sleep apnea and whether using CPAP therapy helps improve these thinking problems.

You will visit the Sleep Center Clinic once for this study. There, trained staff will help you complete an online questionnaire on a computer that takes about 30 minutes. The questionnaire asks about your background (age, work status, health history), your sleep quality, daytime sleepiness, fatigue, and any thinking or concentration problems you've experienced. That's the entire study—just one visit and one questionnaire.
