Has sanjay gupta cited peer-reviewed studies in his alzheimer's video and what are they?

Executive summary
Dr. Sanjay Gupta’s CNN documentary and accompanying articles reference peer-reviewed research and ongoing NIH‑funded trials when discussing Alzheimer’s risk reduction and treatments, and they name strands of research—most notably Dean Ornish’s lifestyle intervention work and investigations into L‑serine—that have appeared in peer‑reviewed literature [1] [2] [3]. However, the publicly available CNN summaries and related reporting in the provided sources do not list specific paper titles, DOIs, or full citations for those studies, so a definitive catalogue of every peer‑reviewed study Gupta cites in the video cannot be assembled from these excerpts alone [4] [5].
1. What the reporting explicitly says Gupta cited
CNN and partner coverage make clear that Gupta’s reporting refers to an NIH‑funded study testing software to reduce Alzheimer’s risk and highlights Dean Ornish’s “peer‑reviewed lifestyle research” as part of the narrative on modifiable risk factors and reversal efforts [1]. The documentary also follows intensive lifestyle intervention programs and places them alongside clinical research as examples of approaches that may slow or reverse early disease progression [6] [2]. In addition, one segment traces an ethnobotanical lineage from research on a Guam neurodegenerative disorder to renewed interest in the amino acid L‑serine as a potential avenue for Alzheimer’s treatment [3].
2. Which named research threads correspond to peer‑reviewed literature
The items named in the reporting map onto bodies of peer‑reviewed work: Dean Ornish’s lifestyle medicine programs have been published in peer‑reviewed journals (the CNN article explicitly calls them “peer‑reviewed lifestyle research”) and are cited in the reportage as a model for multi‑factor interventions that could affect Alzheimer’s risk [1] [2]. NIH‑funded trials are by definition embedded in the formal research ecosystem and typically produce peer‑reviewed outputs when completed, and the CNN summaries explicitly mention Gupta joining an NIH‑funded study testing software to reduce Alzheimer’s risk [1]. The L‑serine line of inquiry described through the Paul Cox story originates in academic observations about neurotoxins in Guam and subsequent experimental work that has been discussed in scientific venues [3].
3. What the provided reporting does not provide — and why that matters
None of the supplied CNN snippets or secondary articles include a bibliography, paper titles, journal names or direct quotations of peer‑reviewed study findings that Gupta cites on screen, so it is impossible from these sources to extract a comprehensive list of primary citations or to verify which exact peer‑reviewed papers Gupta names in the video itself [4] [5]. The documentary format and these summary pieces often summarize research findings for lay audiences without reproducing formal citations; the credits or an accompanying online story sometimes contain more detailed sourcing, but those details are not present in the excerpts provided here [4].
4. Context, caveats and competing views noted in reporting
The reportage frames the field as “the most hopeful era” for patients because multiple approaches—drugs, lifestyle change, supplements and software—are being tested and reported on, and Gupta foregrounds hopeful individual stories alongside research [4] [7]. The L‑serine angle is presented as an “audacious theory” emerging from ethnobotanical and observational work rather than as settled clinical practice [3], while lifestyle interventions are portrayed as showing promising results but positioned as part of ongoing research rather than definitive cures [6] [2].
5. Where to look to verify exact peer‑reviewed citations
To compile the precise peer‑reviewed studies Gupta cites in the documentary, consult the full CNN documentary page and the program’s online companion pieces or episode credits (the CNN report and video pages are the immediate starting points referenced in the reporting) [4] [5]. If the documentary itself does not list formal citations, follow up on the named researchers and trials in academic databases—search terms based on “Dean Ornish Alzheimer’s lifestyle,” the NIH‑funded software trial noted by CNN, and “L‑serine Paul Cox Guam” will locate peer‑reviewed publications that correspond to the threads Gupta highlights [1] [3] [2]. The reporting shows Gupta links to peer‑reviewed research, but the specific paper-level citations are not included in the excerpts provided here, so confirming the exact list requires checking the documentary’s full credits or the accompanying CNN web materials [4] [1].
