- Study Director: Christine Walsh, PhD
- Sponsor: National Institute of Health (NIH) and the Tau Research Consortium
- Official Study Title: The Relationship Between Sleep and Cognition in Older Adults
- Conditions Studied: Healthy aging and neurodegenerative processes, in particular: progressive supranuclear palsy (PSP) and corticobasal syndrome
Purpose of the Study
The purpose of this study is to determine how sleep is affected in both healthy aging and neurodegenerative processes. The study aims to determine whether sleep quality alters performance on cognitive tasks in older adults and whether this relationship changes with mild to moderate cognitive impairments.
Study Details
Inclusion Criteria
- Participant must be in stable medical condition for one month prior to screening
- All participants must be willing and able to undergo testing procedures
Exclusion Criteria
- Major psychiatric disorder within the past two years
- Neurological conditions affecting cognition (e.g., epilepsy)
- Substance abuse or dependence
- Significant systemic medical illnesses (e.g., cancer; renal failure, respiratory failure)
- Current medication likely to affect central nervous system function
- Insulin-dependent diabetes
What to Expect
Testing: If the screening exam shows that you are eligible and you choose to continue, you will be asked to participate in some or all of the following procedures during an 11-day at-home period: questionnaires, sleep journals, sleep/wake measurements, behavioral testing, movement measurements, and an overnight measurement of vitals. You may also be asked to participate in a ~24hr study at the UCSF Clinical Research Center to complete an overnight sleep assessment (polysomnography measurement) and daytime napping assessments.
The Frequency of Visits: The visit typically involves an initial screening at the UCSF Mission Bay campus for instructions on how to use the at-home measurement devices and some cognitive testing. In addition to completing the at-home portion of the study, you may be asked to stay one night and day in the Clinical Research Center at UCSF Parnassus campus. You may be asked to return for follow-up visits within 6–40 months of your original participation.
Materials Needed Before Evaluation: None
Costs: No costs will be charged for any of the study procedures. You may be eligible for travel reimbursements that involve participation in the study. There is no monetary compensation for participation.
