Researchers discovered that exercise strengthens the blood-brain barrier, improving brain function and potentially fighting dementia. A new study found that an exercise protein, GPLD1, boosts brain health by repairing aging barriers and reducing leaky proteins in older mice with Alzheimer’s disease. The findings suggest that regular exercise may repair aging blood-brain barriers and improve brain function in both animals and people.
