Fighting early-stage Alzheimerโs with intensive lifestyle changes works, study finds

As her memory faded from Alzheimerโs disease in her late 50s, Tammy Maida began to lose track of her life. Car keys, eyeglasses and her purse disappeared multiple times a day. Key characters in novels she was reading were forgotten. Groceries were left in the garage. Keeping the books for the familyโs businesses became impossible.
โI honestly thought I was losing my mind, and the fear of losing my mind was frightening,โ Maida told CNN Chief Medical Correspondent Dr. Sanjay Gupta in the 2024 CNN documentary โThe Last Alzheimerโs Patient.โ
After 20 weeks in a randomized clinical trial designed to drastically change her diet, exercise, stress levels and social interactions, Maidaโs cognition improved. She was able to read and recall novels and correctly balance spreadsheets again. A blood test even found levels of amyloid, a hallmark of Alzheimerโs disease, were retreating in her brain, according to the study published in June 2024.
โIโm coming back. It was really good โ like I was prior to the disease being diagnosed,โ Maida, now 68, told a researcher on the study. โAn older but better version of me.โ
Maidaโs cognition showed additional improvement, however, after she completed a total of 40 weeks of intensive lifestyle changes, said principal investigator Dr. Dean Ornish, a clinical professor of medicine at the University of California, San Francisco, and creator of the Ornish diet and lifestyle medicine program.
Ornish gave a study update on Tuesday at the 2025 Alzheimerโs Association International Conference in Toronto.
While not everyone in the 26-person interventional group benefited, some did improve in three of four standardized tests, he said. In fact, 46% showed improvement in one test that measured changes in memory, judgment and problem-solving as well as the ability to function at home, practice hobbies and practice personal hygiene.
โAn additional 37.5% of people showed no decline in cognition during those 40 weeks,โ Ornish said. โThus, over 83% of patients improved or maintained their cognition during the five-month program.โ
โEat well, move more, stress less and love moreโ
The lifestyle intervention Ornish created โ which he calls โeat well, move more, stress less and love moreโ โ has been tested before. In 1990, Ornish showed for the first time in a randomized clinical trial that coronary artery disease could often be reversed with nothing more than diet, exercise, stress reduction and social support.
Additional research has shown the same four-part program can lower blood sugars and heart disease risk in patients with diabetes, reduce prostate cancer cell growth, improve depression and even lengthen telomeres, the protective caps of chromosomes that are worn away by aging.
During the Ornish intervention, one group of people consumed a strict vegan diet, did daily aerobic exercise, practiced stress reduction and engaged in online support groups. The rest of the participants were in a control group and were asked to not make any changes in their daily habits.
Therapists led hour-long group sessions three times a week in which participants were encouraged to share their feelings and ask for support. Meditation, deep breathing, yoga and other ways to reduce stress took up another hour every day. The program also encouraged participants to prioritize good-quality sleep.
Supplements were provided to everyone in the intervention group, including a daily multivitamin, omega-3 fatty acids with curcumin, coenzyme Q10, vitamin C and B12, magnesium, a probiotic, and Lionโs mane mushroom.
In addition to online strength training led by a physical trainer, people in the intervention attended hour-long video classes on vegan nutrition hosted by a dietitian. Then, to ensure a vegan diet was followed, all meals and snacks for both participants and their partners were delivered to their homes.
Complex carbs found in whole grains, vegetables, fruits, tofu, nuts and seeds made up most of the diet. Sugar, alcohol and refined carbs found in processed and ultraprocessed foods were taboo. While calories were unrestricted, protein and total fat made up only some 18% of the daily caloric intake โ far less than the typical protein intake by the average American, Ornish said.
