Dementia: bad news; good news; ignored news

First, the bad news, summed up in this item from the BBC: there are more people in the UK with dementia than previously thought, and the effect of dementia on society and the economy has been significantly underestimated. The good news, also from the BBC, is a summary of things that have been shown to help reduce your chance of developing dementia by as much as 20%. The ignored news in all this publicity is, of course, the role that technology can play in helping people with pre-late-stage-dementia to mange their lives and reduce the risk of harm.
