Healthy living may help offset genetic risk of dementia: study

Living healthily with a good diet and regular exercise may help people with a higher genetic susceptibility to dementia to offset the risk of developing it, according to recent research. The risk of dementia was reduced by 32% in people with a high genetic risk if they had followed a healthy lifestyle, compared to those who had an unhealthy lifestyle, the study, published in the medical journal JAMA on Sunday, found. People with high genetic risk and an unhealthy lifestyle were almost three times more likely to develop dementia than those with low genetic risk who also lived healthily.
