Obstructive Sleep Apnea Clinical Trial
Official title:
The Effect of Obstructive Sleep Apnea and Its Treatment on Decision Making
Obstructive sleep apnea (OSA) is an extremely common disease with inadequately explored neurocognitive consequences. The investigators will study OSA patients before and after treatment to understand how OSA changes decision making abilities, and whether treatment can reverse such cognitive changes. These results could provide deeper insight into how OSA affects decision making either temporarily or permanently, and provide another rationale or motivation for treatment of OSA in adults.
The investigators hypothesize that OSA will lead to (H1) more reward-seeking and lower payoffs in the Iowa Gambling task, replicating previous findings; (H2) greater discounting of future rewards in financial choices; and (H3) these effects would dissipate when OSA is successfully treated. In order to test these hypotheses, the investigators will perform cognitive tests (Iowa gambling; intertemporal choice; other measures) in 100 patients about to undergo sleep testing. It is expected that of these 100 patients, some will have no sleep apnea; some will have sleep apnea and will be successfully treated; and that some will have sleep apnea but will not be successfully treated by the time of repeat testing. The investigators will repeat testing using the same instruments 2 months later. Thus the investigators will be able to compare whether OSA patients differ from control at baseline (t1), and whether OSA patients' performance will improve after treatment at t2, compared to the control at t2. ;
