Being aerobically fit in middle age may reduce Alzheimer’s and dementia risk, study says
CNNCNN — Doing more aerobic exercise in middle age and old age may reduce the risk of dementia, including Alzheimer’s disease, a new study found. “Our study underscores the critical role of cardiovascular fitness in reducing dementia risk, even for those genetically predisposed to Alzheimer’s disease,” said Weili Xu, a professor in the Aging Research Center at Karolinska Institute in Stockholm. “While in this study higher fitness alone delayed onset of dementia by 1.5 years, we can do even better by also following a healthy diet, managing cholesterol, blood pressure and blood sugar, getting regular hearing and vision checks, and prioritizing sleep.” The importance of cardiorespiratory fitness Studies show a low level of cardiorespiratory fitness is a strong predictor of cardiovascular disease such as heart attacks and premature death from all causes, including cancer, according to studies. “The same risk factors that affect cardiovascular disease may play a role in the development of vascular dementia, and even there is some data suggesting they play a role in the acceleration of the Alzheimer’s disease.” How to build aerobic fitness What’s the best way to increase your cardiorespiratory fitness and protect your heart and brain?
