Keeping your brain sharp with age may depend less on luck and more on lifestyle. A major new study published in JAMA found that seniors who followed a structured daily routine centered around healthy habits showed slower cognitive decline than those who didn’t.
Researchers followed more than 2,100 adults between 60 and 79 years old who were at higher risk of developing dementia or Alzheimer’s disease. Their findings suggest that staying active—physically, mentally, and socially—can delay memory loss by as much as one to two years. Here’s what the study revealed and what experts recommend for maintaining brain health after 60.
What the JAMA study revealed about structured routines
The trial tested two lifestyle programs designed to improve brain health. Both encouraged better diet, regular physical activity, and social engagement, but one included structured support—group meetings, brain-training sessions, goal setting, and personalized feedback from clinicians.
After two years, both groups improved their cognitive scores, but participants in the structured program saw significantly greater benefits. Their rate of decline slowed by one to two years on average, according to Laura Baker, professor of gerontology and geriatrics at Wake Forest University School of Medicine.
The impact was consistent across participants, including those with genetic risk factors for Alzheimer’s, such as the APOE4 gene, and those who already showed signs of amyloid buildup in the brain. That’s encouraging news for anyone worried about cognitive decline running in their family.
Participants who had guidance, accountability, and social support were more likely to stick with new habits—whether it was exercising, eating healthier, or doing online brain-training games. Gradual goals also made it easier to sustain change over time, starting with just 10 minutes of daily movement and slowly building from there.
Baker says the study provides strong evidence that cognitive decline isn’t inevitable. “It doesn’t reverse the clock,” she explained, “but it’s very clear that it can slow, and pull back the clock by one to two years“. The researchers plan to continue following participants for several more years to measure whether these lifestyle changes also reduce the incidence of dementia.
Simple habits to protect your brain health
The study’s message is that structured routines can impact the way the brain ages. Even small changes can help, and the earlier you start, the better.
- Move your body daily. Moderate exercise improves blood flow to the brain and helps maintain memory. Aim for 30 minutes of walking, cycling, or light strength training most days of the week.
- Eat a balanced, heart-healthy diet. The Mayo Clinic and Alzheimer’s Association recommend diets rich in fruits, vegetables, fish, whole grains, and olive oil. Blueberries, in particular, are linked to slower cognitive decline due to their antioxidant content.
- Stay socially active. Regular contact with friends, family, or community groups helps keep the brain engaged and reduces isolation, a known risk factor for cognitive decline.
- Keep your mind challenged. Reading, puzzles, learning a language, or online brain-training exercises stimulate different parts of the brain and may improve processing speed and memory.
- Get enough sleep and manage stress. Restorative sleep helps clear amyloid proteins from the brain, while chronic stress can speed up decline.
Consistent habits—especially when supported by social connection and accountability—can help preserve memory, attention, and problem-solving skills well into later life. Even one small step toward a healthier routine can help your brain stay stronger for longer.
