My sister Joanne was diagnosed with vascular dementia a few years ago and she is in her early 50’s. I'm running the TCS London Marathon for Dementia UK.Dementia UK is the specialist dementia nurse charity. Their nurses, called Admiral Nurses who they continually support and develop provide life-changing care for families affected by all forms of dementia, including Alzheimers disease.Please help me support their amazing work. When you support Dementia UK, youre helping grow the number of specialist dementia nurses. With your help, no one will have to face dementia alone.
