"In early 2011 I was struck by the first of two brain haemorrhages. I am hardly unique or alone in that. 1 in 3 people will suffer a brain injury in their lifetime. That number is huge. It’s almost double the number of people who will develop dementia. It’s shocking to me - and you too, probably - that such a common health problem is so little known and barely spoken about. I made a full recovery but many more people don't, and I want to break the silence on this common, silent and devastating condition."
