Study Summary
The purpose of this study is to determine whether obstructive sleep apnea affects sleep dependent memory and learning. Subjects with apnea will be given a test of perceptual skill learning (the Visual Discrimination Task (VDT)) that has previously been shown to depend on sleep. Subjects will be tested on this task before and after sleep. The difference in performance after sleep compared to before sleep provides a measure of sleep dependent learning. Participants will be tested on one night when they have less apnea because they are using continuous positive airway pressure (CPAP) as prescribed by their physician, which is well known to reduce apnea; and on another night when they are in their native state and have a greater degree of apnea. Memory performance will be compared between the two nights to determine how apnea affects sleep dependent memory.
Primary Outcome
Learning on the visual discrimination task (VDT) is measured by comparing performance on the perceptual task at a baseline session prior to sleep to that in a second session after sleep. Subjects are standardly tested in the hour prior to their typical bedtime, and re-tested after spontaneously awakening after a night of sleep. Sleep is known to consolidate learning on this task, such that more robust learning occurs after an interval of sleep compared to when the patient is awake over the same
