Episode #337. An estimated 45% of dementia cases are preventable – find out how you can reduce your risk by targeting these 14 modifiable factors. Today I’m joined by Dr Kellyann Niotis, the first fellowship-trained preventive neurologist, to explore the latest research on dementia prevention and how simple lifestyle changes can dramatically reduce your risk.
