A new study released shows that girls who exercise in their adolescence have a decreased chance of developing dementia later on in life. While the evidence is not 100% conclusive, it does show that physical activity early in life is important for health later in life. The two theories that may explain this phenomenon are that exercise may prevent blockage in the blood vessels that supply the brain or exercise helps develop new connections within the brain, which help it function later on. Encourage all children to exercise, and come up with ways to make it fun with family and friends.
