Alzheimer's Study at Harvard: New research indicates that intensive diet and lifestyle changes might not only slow cognitive decline in early Alzheimer's patients but also potentially improve their cognitive abilities. This small, preliminary study, published in June in Alzheimer’s Research & Therapy, suggests promising results but calls for more extensive, longer trials to confirm these findings.
Surprising Results in a Short Time
The study's senior authors, Dr. Rudolph Tanzi and Dr. Steven Arnold from Harvard Medical School and Massachusetts General Hospital, expressed excitement and caution about the results. Over 20 weeks, the study involved 51 participants with mild cognitive impairment or early dementia. Those in the intervention group followed a strict vegan diet supplemented with nutrients to support brain health, engaged in daily exercise and stress reduction activities, and participated in regular social support sessions.
Lifestyle Interventions
Participants in the intervention group adhered to the following lifestyle changes:
- Diet: A vegan regimen with supplements such as omega-3 fatty acids, curcumin, and various vitamins.
- Exercise: 30 minutes of aerobic exercise daily and strength training three times weekly.
- Stress Reduction: Daily yoga, meditation, stretching, and breathing exercises.
- Social Support: Hour-long support group sessions three times a week.
Promising but Preliminary Findings
The results showed that participants in the intervention group either improved or maintained their cognitive performance, while those in the control group either remained the same or worsened. One critical cognitive test revealed that over 40% of the intervention group improved, compared to none in the control group. Additionally, the intervention group improved several biomarkers related to Alzheimer’s disease and overall health.

However, Dr. Tanzi and Dr. Arnold emphasized the need for more research. "I want people to be intrigued and enthused by its findings but not overinterpret them because more data is needed," said Dr. Arnold.
Next Steps
The researchers plan to conduct more extensive, longer studies to verify these initial results and explore whether participants can sustain such intensive lifestyle changes over time. Despite the study's small sample size and the impact of the COVID-19 pandemic on enrollment and implementation, the findings are encouraging and suggest that lifestyle interventions could play a significant role in managing Alzheimer's disease.
"This should be looked at as a pilot study, but the pilot data are significant and strongly suggest that lifestyle intervention was effective," Dr. Tanzi concluded. Stay updated with similar articles by following Education Post News.
