Consequently, research efforts to understand, and therefore potentially model, the effects of sleep quality on cognition and brain health are of great pragmatic values.","overall_status":"Completed","phases":[],"study_type":"OBSERVATIONAL","sponsor":"Chinese University of Hong Kong","enrollment":238,"countries":["Hong Kong"],"start_date":"2023-10-01","completion_date":"2025-01-10","last_update_date":"2025-01-14","source_url":"https://clinicaltrials.gov/study/NCT06170073","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
