Dementia is the highest cause of death in the UK, says the Naked Attraction host – whose father has been diagnosed. This is a moving, scary look at the condition

Seeing someone suffer from dementia is extremely painful. My hope, as I watched people struggle with the condition, was that, as hard as it was to see them lost and confused within the prism of their own mind, perhaps they might not have been as acutely aware of the tragedy of their circumstances as those of us around them. That thought made it a little easier to bear.

Dementia will, at some point, affect every one of us in some way. As Anna Richardson’s Channel 4 documentary lays out, it is the highest cause of death in the UK and, as the presenter grimly states, it’s predicted that a third of us will develop it in our lifetimes.
