How fitness boosts memory in older adults with MCI

Plenty of research has shown that exercise is linked to brain health, with some studies suggesting fitness may even improve memory. But what happens during exercise to trigger these benefits? A study from UT Southwestern, Dallas, Texas, that mapped brain changes after one year of aerobic workouts has uncovered a potentially critical process: Exercise boosts blood flow into two key regions of the brain associated with memory. Notably, the study showed this blood flow can help even older people with memory issues improve cognition, a finding that scientists say could guide future Alzheimer's disease research.
