Hi, I know that UTIs are a part of dementia although I don't know why but does anyone else find that they are linked to some form of shock or trauma? My dad is very unsteady when walking so frequently stumbles. On Wednesay evening he took a tumble and ended up on the floor. Two days later he has a UTI and a chest infection ( he has COPD so this could occur at any time). This seems to be becoming a pattern with him. after every tumble of fall, no matter how small he becomes totally disorientated, loses most of his retained memories and becomes so weak he can't stand. Is this normal? The care home staff just tell me not to worry but I feel that I need the control of knowing if this is "par for the course" or something I should be investigating further for his sake.
