Is dementia on the rise?

Chris answered this question...

Chris - Well actually it's both Anand. We're seeing better pickup because we know what we're looking for but, also, people are living longer. We've got an ageing population and that means more people are living long enough to develop dementia. And the stark reality is at the moment there are about 30 million people in the world with dementia; within the next 30 years or so, that number's set to climb to 150 million. It could become as much as a third of the populations of some western countries. So, certainly, governments are very very worried about how we're going to care for these people with these problems in the future...
