Exercise at One Stage of Life May Cut Dementia Risk by Up to 45% : ScienceAlert
Regular physical activity during midlife may offer powerful long-term protection against dementia, according to new research highlighted by ScienceAlert. The study suggests that staying active in your 40s and 50s can reduce dementia risk by as much as 45 percent later in life. Researchers believe exercise supports brain health by improving blood circulation, reducing inflammation, and enhancing the brain’s ability to form new neural connections. While genetics and age still play major roles, lifestyle habits such as consistent movement appear to make a significant difference. The findings emphasize that even moderate activities—like brisk walking, cycling, or household chores—can contribute to better cognitive health over time. This research adds to growing evidence that healthy routines established early can help protect memory, thinking skills, and overall brain function as we age. The message is clear: prioritizing physical activity now may offer strong mental benefits decades later.
