Kaarin Anstey, UNSW Ageing Futures Institute, Sydney, Australia, explains the importance of preventing dementia, especially as there is no effective treatment or cure. The guidelines set out by WHO will delay and prevent cognitive dysfunction in individuals with either dementia or cognitive impairment. Further, Prof. Anstey concludes that these guidelines are concordant with the management of other chronic illnesses such as heart disease or diabetes. Therefore they will have a myriad of positive impacts across the spectrum, promoting healthy aging. This interview was recorded during an online conference with The Video Journal of Dementia (VJDementia).
