Dementia is a disease that becomes more and more common in later ages. We do not know for sure what causes it, and this also limits our ability to diagnose it.
There are a number of lifestyle changes you can make to support your brain health and increase your cognitive reserve. Professor Claire Steeves is a consultant geriatrician at Guy's and St Thomas' NHS Foundation Trust and a senior lecturer at King's College London. She talked about how important it is to look after our teeth, what role our genes play, how our diet and exercise can affect our chances of developing dementia.
