This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand what happens in the brain when someone has obstructive sleep apnea (a condition where the airway closes repeatedly during sleep). Using a special brain imaging machine called functional MRI, they will look at brain activity in people with severe sleep apnea and compare it to people without sleep apnea. The study will also check whether these brain changes affect thinking and memory.
Sleep apnea causes repeated pauses in breathing at night, which may strain the brain and affect how people think during the day. Researchers don't yet fully understand how the brain tries to compensate for this stress while awake, or whether this compensation affects memory and concentration. This study aims to fill that gap.

You will visit the research center and lie inside a functional MRI machine (a large scanner that takes detailed pictures of your brain) while researchers monitor your brain activity. The scan is painless and typically takes about an hour. You may also complete some thinking and memory tests, and answer questions about your sleep and mood. The study compares brain activity between people with sleep apnea and those without to see if there are differences.
