Dr Norman Swan and the Tonic team look at the positive impact of aerobic excercise on dementia risk.

Regular aerobic exercise, such as jogging, cycling and swimming, has countless benefits for your health, but what not many people realise is that it might also improve brain function and can help prevent the onset of neurodegenerative diseases like Alzheimer's disease, Parkinson's disease and even cognitive impairment itself. Dr Norman Swan sits down with Professor Ron Peterson from the Mayo Clinic to discuss the latest findings regarding aerobic exercise and dementia.
