David Cameron has announced funding for research into dementia is to be more than doubled by 2015 in a bid to make Britain a world leader in the field.

The Prime Minister has declared that tackling the "national crisis" posed by the disease is one of his personal priorities.

  • Around 700-thousand people across the UK have been diagnosed with dementia.

  • But those numbers are expected to increase to 1 million in the next decade.

  • The costs associated with dementia are estimated to be 23 billion pounds.

  • Higher than those for cancer, heart disease or stroke.

  • The government now wants to more than double its funding for research from £26.6 million to £66 million by 2015.
