Moderate exercise gives memory boost

Research carried out by the University of Pittsburgh in the US has revealed that moderate exercise in middle age can improve memory.

Walking for just forty minutes several times a week can increase the size of the hippocampus which is the part of the brain that stores memories. The research involved healthy people in their 60’s but the results may have positive implications for ageing societies where dementia is on the increase.

Leader of the research project, Professor Kirk Erickson, said “We think of the atrophy of the hippocampus in later life as almost inevitable. But we’ve shown that even moderate exercise for one year can increase the size of that structure.”
