The hon. Gentleman raises a very important issue. He mentioned the number of his constituents who are living with dementia. Across all our constituencies, there are increasing numbers of people living with the condition. That is why we have committed to delivering our dementia 2020 challenge in full. The challenge supports research into dementia, which he specifically mentioned. The UK research community is playing a significant role in the global effort to find a cure or a major disease-modifying treatment by 2025. We have committed to double spending on dementia research by 2020—the equivalent of around £60 million per annum—and we are on track to meet that commitment. As he referenced, much of this investment is for research to better understand the nature of dementia, to inform the development of future treatments and to find ways to prevent the onset of the condition. Preventing the condition is of course the best route to take. Meanwhile, we look to provide better treatment for those with the condition.
