One in three stroke victims will be struck down within five years and one in 10 will get dementia within 12 months, say experts.
It means that more than 33,000 people will be ravaged by the incurable condition – with three quarters having vascular dementia, the second most common type after Alzheimer’s, which is linked with blood supply problems to the brain.
The crisis has prompted three of Britain’s biggest charities to join forces and fund a research programme to try to defuse the looming health timebomb.

Professor Joanna Wardlaw, of Edinburgh University, said: “By comparing those who develop vascular dementia after stroke with those who don’t we hope to find out what causes it and find a way to prevent it.”
