## Summary

Exercise programs mixing cardio, strength and balance work were linked to better overall thinking and mental flexibility. This held in older adults with mild cognitive impairment (an early stage of memory and thinking decline), pooled from 10 trials with 623 people. For anyone with a parent showing early memory slips, it adds weight to well-rounded exercise programs. Still, the trials were small, evidence for overall thinking was rated low quality, and effects on BDNF (a brain growth protein) stayed unclear.

## Practical Takeaway

This review suggests varied exercise may support thinking skills in people with mild memory decline.
