Have Sanjay Gupta and Bill Gates co-authored papers or studies on Alzheimer’s disease?

1. Public roles: journalist-author versus funder‑philanthropist

Dr. Sanjay Gupta appears in these sources primarily as a journalist, author and clinician—writing CNN features, producing documentaries and publishing a popular book on brain health—activities documented in CNN reporting and book listings ^{[1] [4] [5] [3]}, while Bill Gates shows up as a private funder and public advocate, investing in research vehicles like the Dementia Discovery Fund and announcing initiatives in interviews with Gupta ^{[1] [2]}; those distinct public roles explain why one would expect reporting and philanthropy rather than shared laboratory papers ^{[1] [2]}.

2. Where the documented interaction exists: interviews and coverage, not co‑authorship

The record provided includes multiple interactions between Gupta and Gates in the form of interviews and feature reporting—Gupta sat down with Gates for CNN pieces about Gates’s Alzheimer’s investments and ambitions ^{[1] [2]}—but these are journalistic collaborations, not scientific collaborations, and none of the cited pieces claim or cite a co‑authored peer‑reviewed study authored by both men ^{[1] [2]}.

3. Bill Gates’s scientific involvement is mainly as funder and advocate, not as a named academic co‑author in these sources

The sources describe Gates committing personal funds to initiatives such as the Dementia Discovery Fund and advocating for diagnostics and novel research directions ^{[1] [2]}, which is a common philanthropic pathway that supports many studies without placing the funder on study author lists; the provided reports do not list Gates as a co‑author on any specific Alzheimer’s research papers ^{[1] [2]}.

4. Sanjay Gupta’s Alzheimer’s work is reporting, public education and a popular‑press book, not framed here as original lab research

Gupta’s outputs in the sources are journalistic investigations, documentary reporting and a best‑selling book on brain health that synthesize and translate research for the public ^{[3] [5] [6]}; the Butler Hospital piece and CNN coverage show Gupta summarizing and contextualizing scientific findings rather than presenting primary research studies authored by him and others ^{[7] [1]}.

5. Absence of evidence is not proof of absolute non‑existence — caveats and limitations of the reporting

The conclusion rests on the documents provided, which include news articles, book pages and feature reporting that make no claim of co‑authored scientific papers by Gates and Gupta ^{[3] [1] [2] [4]}; these sources do not constitute a comprehensive bibliographic search of scientific databases, so they cannot definitively rule out a jointly authored paper elsewhere, but within this set there is no sign of co‑authored peer‑reviewed Alzheimer’s research ^{[1] [2]}.

6. How the relationship could be misread and why narrative framing matters

Because Gupta reports on Gates’s Alzheimer’s philanthropy and has profiled Gates on CNN, some readers may conflate journalistic collaboration and advocacy with scientific co‑authorship; the sources explicitly show interviews and funding announcements—contexts that create public association but do not equal shared academic authorship ^{[1] [2]}. The implicit agenda in coverage—Gupta illuminating a high‑profile funder’s commitment, and Gates publicizing philanthropy—benefits both parties’ public missions (raising awareness, legitimizing funding) without implying joint research publications ^{[1] [2]}.

7. Bottom line

Based on the provided reporting, Sanjay Gupta and Bill Gates have collaborated in media (interviews and coverage) and Gates has funded Alzheimer’s research, but there is no evidence here that they have co‑authored scientific papers or formal studies on Alzheimer’s disease; a definitive answer about all possible publications would require direct searches of academic bibliographic databases, which the current sources do not provide ^{[1] [2] [3]}.
