Extra Weight Could Age Your Brain Faster, Study Warns

A 24-year study of more than 8,200 adults over 50 found that higher cumulative BMI was linked to faster decline in memory, overall cognition, and executive function.

The association was strongest in older adults, suggesting body weight may play a bigger role in brain aging later in life.

Researchers said weight management could be a modifiable way to help slow cognitive decline and lower dementia risk.
