Using Wearables to Find Clues About Mild Cognitive Impairment and Early Alzheimer’s

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to collect continuous data from wearable devices to detect patterns in activity, sleep, and other metrics that may be associated with early cognitive decline. Participants 65 and older with suspected MCI or early AD will wear devices for 30 days while completing questionnaires and standard assessments. The goal is to see if wearable-derived signals can help identify at-risk individuals and inform earlier diagnosis and personalized care planning. The study is led by Getúlio Vargas University Hospital, with collaboration from Universidade Federal do Amazonas and Samsung Eletrônica da Amazônia LTDA, and it takes place in Manaus, Brazil. No interventions are being tested beyond device wear and data collection.
