My grandad died last year after nigh on a decade of going down hill, he’d got to the point of assaulting people 5 mins after they’d arrived in his house thinking they were burglars, it’s a shame to say and a right corny line but I know it’s easier for my grandma now his gone as she was his full time carer, in the end he couldn’t even recognise her 😥 It’s a damn cruel disease
