Brain Energy Metabolism and Sleep in Adults

Start: November 30, 2018
End: December 31, 2022
Enrollment: 60

What Is This Study About?

The first phase of this study will investigate the relationship of sleep abnormalities, genes, and brain energy on cognition in people who are cognitively normal, have mild cognitive impairment, or have Alzheimer's disease. The second phase will test the effects of an oral airway management system on sleep and cognition. Participants will complete neurocognitive testing, genetic testing for Alzheimer's risk genes ApoE4 and ABCA7, a sleep assessment, and an MRI scan. For the second phase of the study, participants with abnormal sleep and upper airway obstruction will be invited to use the myTAP device for three months followed by neurocognitive testing and sleep assessment. myTAP is approved by the U.S. Food and Drug Administration for the treatment of snoring and obstructive sleep apnea.
