Expanding Access to Cognitive Health Biomarker Testing at Home

Enrolling By InvitationN/A

Sponsor: University of Virginia

Conditions: Mild Cognitive Impairment (MCI), Alzheimer's Dementia (AD), Subjective Cognitive Decline (SCD), Cognitive Aging

Countries: United States

The goal of this observational study is to learn whether at-home blood biomarker testing for Alzheimer's disease risk is feasible and acceptable in older adults with cognitive concerns. The main questions it aims to answer are: * Can older adults with subjective cognitive concerns or possible mild cognitive impairment successfully complete a fully remote workflow that includes at-home capillary blood collection, overnight shipping, central laboratory analysis of phosphorylated tau-217 (p-tau217), and remote disclosure of results by a neurologist? * Is this remote at-home p-tau217 testing workflow acceptable to participants? Participants are adults aged 65 and older who participated in the SHUTi MIND parent study (NCT05565833) and report subjective cognitive concerns or screen positive for possible mild cognitive impairment. Participants will collect a small capillary blood sample at home, return the sample to a central laboratory by overnight shipping for p-tau217 analysis, receive their result during a remote visit with a board-certified neurologist, and complete online surveys at baseline, after results disclosure, and 6 months post-disclosure.
