Preventing Dementia (parts 1 and 2)

This is a talk I gave on 6th May 2023 for a Yarra City Council community event run by charity Green Karma. It covers the key issues around preventing dementia, including treatment options and key risk factors. No surprise but a healthy diet and healthy other lifestyle behaviours can reduce dementia risk up to 90%.
