A Lancet study shows that moderate–vigorous exercise slows Alzheimer’s-related changes in the brain (tracked by a biomarker called p-tau181).
- Older adults who stayed active had a slower rise in Alzheimer’s markers.
- Even low activity helped, though benefits dropped in those already showing higher disease signs.
- For young adults: building active habits now = stronger brain health later.
Takeaway: Stay active (walk, bike, swim, lift). Your future brain will thank you.
