Staying Active and Engaged

Staying physically, mentally and socially active is one of the best things you can do after a dementia diagnosis; new research suggests even 3,000 to 7,500 steps a day may help, and here's how to keep doing what you enjoy.

Last reviewed: October 2026

A diagnosis of dementia or mild cognitive impairment doesn't mean giving up the things that make life good. Staying active, in body, mind and social life, helps people feel better, sleep better, stay independent longer and keep a sense of purpose. It's one of the most important parts of living well with dementia.

Why it matters

What the research shows about walking

In a study published in Nature Medicine in late 2025, researchers at Mass General Brigham tracked the daily step counts of almost 300 older adults who didn't yet have memory problems, and followed them for about 9 to 11 years. Among people who already had early Alzheimer's changes (amyloid) in the brain, those who walked more had slower decline in thinking and daily function, and less buildup of tau, the protein that tracks closely with symptoms. Benefits appeared at about 3,000 steps a day, and were strongest at about 5,000 to 7,500, well below the famous 10,000.

This was an observational study, and the people in it had no symptoms when it began, so it doesn't prove that walking slows dementia once it's diagnosed. But it adds to a large body of research showing that physical activity is good for the brain at every stage. See Exercise and the Brain.

Ideas for staying active

Move your body

Check with your doctor before starting something new, especially if you have heart problems or balance issues.

Keep your mind busy

Stay connected

See Social Connection for why relationships matter for the brain.

Making activities work as things change

For care partners

Look for activities that match the person's past interests, abilities and mood. Doing things together, like folding laundry, walking the dog or listening to favorite songs, counts. The Alzheimer's Association suggests planning a mix of physical, social and creative activities through the day. If someone refuses, try again later or offer a simple choice.
