I wrote on here a few days ago about my Dad, he's had a CT scan it waiting for a MRI scan plus he's seeing a psychiatrist in a couple of weeks although there is a lot of attention towards my Dad and the 99.9% chance he has Dementia . I have concerns about my mum, she seems angry with him and just in general, I have concerns that she may also be possibly showing signs of cognitive behaviour. They are both 77 nearly 78 years of age. I'm struggling with this.
