Peripheral Arterial Tonometry and Neurocognition in Sickle Cell Disease

Interested participants will be consented in-person or virtually. Consented participants will be mailed the equipment (WatchPAT) to conduct the remote assessment. Additional questionnaires will also be sent via mail or email for the participant to complete prior to collecting data on sleep behaviors. After receiving the questionnaires and equipment, a virtual session will be conducted with the participant to provide education on how to use the equipment and complete the included questionnaires. Participants will wear the WatchPAT overnight for three days and data will be captured remotely. After wearing the devices for three consecutive nights, the participant will attend a research visit within approximately the next two weeks where they will complete performance based neurocognitive assessments, behavioral rating forms, and neuroimaging.
