Presenting CADAS at AAIC 2026 in London
Published:
On July 12 I presented at the Gateway/HCAP consensus session at the Alzheimer’s Association International Conference (AAIC) in London, sharing work from the Caribbean American Dementia and Aging Study (CADAS) on a multinational framework for online cognitive impairment diagnosis.
The short version: twenty-seven clinicians from five countries (the Dominican Republic, Mexico, Puerto Rico, the United States, and India) independently classified 300 older adults using CADAS survey data, applying a structured 10-question NIA-AA diagnostic algorithm through a web-based consensus platform. Each case was reviewed by at least three clinicians per country team, cases with within-country disagreement went to moderated consensus discussion, and international consensus was defined by majority rule across all five teams. The figure above gives a taste of the results: the country teams classified dementia at noticeably different rates, and their disagreement with the international consensus ranged from 2% (United States) to 10% (India). Getting clinicians on three continents to review the same evidence through one platform is as much a coordination problem as a clinical one, and seeing it work end to end was the most satisfying part of the project.
A huge thank you to all of my coauthors for their contributions, especially William Dow, Jorge Llibre-Guerra, and Jinkook Lee of the Gateway to Global Aging project.
It was a pleasure meeting everyone there. London itself was a highlight (the whole city is like a museum), and I’m looking forward to presenting at AAIC again someday.
