This pilot aims to address health inequities in Nepal’s aging population by testing and improving blood sample collection procedures as part of a new survey on Alzheimer's disease and related dementias (ADRD). The project, situated within the Chitwan Valley Family Study, will develop logistical protocols, train staff, and create a blueprint for integrating biomarker data into large population studies. This initiative will enhance research capabilities in Nepal, contributing to a more competitive NIH grant application and establishing a data infrastructure for health research. Key activities include developing the blood sample collection protocol, conducting a pilot test with 50 participants, and establishing a process for transporting samples to a central lab in Kathmandu and then to Ann Arbor.
