  •  The above number is predicted to rise as the population ages
  •  25 million people or 42% of the UK population know someone who has a dementia
  •  Only 2.5% of the governments medical research budget is spent on dementia research
  •  Nationally – every 3.2 minutes a new case of dementia occurs
