Living with early onset dementia is not easy

Former rugby players are 2 and a half times more likely to develop degenerative brain disease and 15 times more likely to get motor neuron disease than the general public. These were the findings of a major new study from Glasgow University and Queen Elizabeth University Hospital which looked at more than 400 Scottish former international players compared with some 1200 members of the public. The study, which has been published in the Journal of Neurology, Neurosurgery & Psychiatry, also found the former rugby players were three times more likely to develop Parkinson's disease. Former All Black prop Carl Hayman played around 450 matches during his career and believes that's what led to his diagnosis of early-onset dementia. Here's the 42 year old's partner, Kiko Matthews, explaining what it's like for Carl day to day.
