My mum took a fall about 3/4 weeks ago. Thankfully she didn’t physically hurt herself. Since then we have lost part of mum. She is 79, normally very independent, relatively healthy and very on the ball with things. This isn’t the case now. She has had a CT scan that showed everything was “ok”. She has been referred to a memory clinic which will take a few months now because of covid. My questions are, is it possible for someone to fall and end up with dementia? And does some types of dementia not show up on a CT scan?
