Dementia remains a daunting global challenge, with a new case emerging every three seconds and over 55 million people affected worldwide as of 2020. However, recent research by Dr. Dean Ornish, a professor of medicine at the University of California, San Francisco, offers a glimmer of hope. Published in the journal Alzheimer’s Research & Therapy, Ornish’s study suggests that comprehensive lifestyle changes could not only slow dementia’s progression but potentially reverse it.
Ornish is renowned for his earlier work showing that lifestyle changes could reverse heart disease. Now, he applies the same principles to brain health. His approach emphasizes diet, exercise, stress management, and social connections, encapsulated in his mantra: “Eat well, move more, stress less, and love more.”
Driven by personal experience—his mother and other family members suffered from dementia—Ornish conducted a study involving 51 adults in their 70s with mild cognitive impairment or early Alzheimer’s. Participants were split into two groups: one adopted a plant-based diet, engaged in regular exercise, practiced meditation or yoga, and socialized more; the other group made no lifestyle changes.
After five months, the results were striking. Seventy percent of the control group experienced cognitive decline, while 70% of those who embraced lifestyle changes showed stability or significant improvement. Some participants who had ceased reading or managing daily tasks found themselves able to resume these activities, highlighting the profound impact of the interventions.
The positive outcomes extended beyond the study period. Cici Zerbe, initially in the control group, adopted the lifestyle changes post-study. Five years later, as documented in CNN’s “The Last Alzheimer’s Patient,” Zerbe exhibited reversed symptoms, attributing her improved condition to daily walks and dietary adjustments.
Neurologist Dr. Richard Isaacson, from the Florida Atlantic University Centre for Brain Health, further supports lifestyle interventions. His patient, Simon Nicholls, managed to reverse Alzheimer’s markers and improve brain function through lifestyle modifications. Isaacson recommends a plant-based diet, regular exercise, and monitoring blood sugar levels for optimal brain health.
Ornish’s research and similar studies underscore a hopeful message: adopting healthier lifestyles can significantly impact brain health and mitigate dementia risks. This proactive approach fosters not only physical wellness but also mental resilience, offering a promising path forward in the fight against Alzheimer’s disease.
