Welcome! This site describes the neuroimaging component of the Harmonized Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India (LASI-DAD).
The overall goal of LASI-DAD is to study late-life cognition and dementia in India. LASI-DAD collects a rich set of cognitive, health, lifestyle, environmental and biomarker data. More information on LASI-DAD, including how to access its publicly available data, is available here.
As part of LASI-DAD Waves 1 and 2 (and as planned for Wave 3), high-quality brain imaging data has been or will be collected using 3 Tesla MRI scanners at multiple sites across India. Please check out the pages that describe the imaging in each wave. Data Requests has info on how to access imaging data.
