For families and friends, the worst symptoms of a brain injury are changing in personality. We've formed relationships with people we like and know, but after brain injury, they become a different person. They don't know they are different but they are!
They won't necessarily remember the memories they have made before, they will have different likes and dislikes. It's not the person we've signed up to spend our whole lives with, yet family carers feel obliged to stay with that person, but there are times when that is no longer possible.
