I have had the privilege of being an ambassador for Alzheimer's Society for a number of years now. My grandmother, Nans, lived with Alzheimer's for half the time that I knew her... Here is my plea. This World Alzheimer's Day - and beyond it - let's do everything in our power to make sure people don't have to face dementia alone. Let's speak up and speak out about dementia so awareness and understanding across society is improved. Let's come together and unite against dementia. If you have a loved one with dementia, spend time with them. Love them, the same way you always have.
