Following a stroke, the brain exhibits a remarkable and counterintuitive response. While the brain regions directly affected by the stroke show accelerated aging, researchers studying over 500 stroke survivors have uncovered that the opposite, unaffected hemisphere can actually appear biologically younger. This intriguing phenomenon is believed to be the brain’s inherent mechanism for adaptation and recovery, as it actively rewires and strengthens healthy neural pathways to compensate for the functions lost due to the injury.
