According to a Science magazine study on mice, physical exercise can help “clean up” the Alzheimer’s brain. Exercise allowed new nerve cells in the hippocampus (the part of the brain involved in memory and learning) to start cognitive repair.
Exercise can create biochemical changes that mend nerve cell health. In the study, active mice had enhanced memory in comparison to inactive mice. (All mice in the study had memory issues that mirrored Alzheimer’s.)
