Ask the man in the street what’s driving Alzheimer’s and they’ll probably say a third is in the genes. Or that it’s just what happens when you age. Neither of these statements are true. Alzheimer’s is a largely preventable disease and my guests today are tackling the two fundamental questions. Firstly, what are the positive and negative behaviours – diet, lifestyle, environment – that prevent and drive dementia? And secondly, how do you change those behaviours. In today’s podcast I talk with Assistant Professor Tommy Wood, from the University of Washington about the what, then Dr Kristina Curtis, a behavioural scientist and honorary lecturer at the University College London who heads the Applied Behaviour Change team, about the how of behaviour change.
