My mum's only diagnosis of vascular dementia was by her GP - she had no tests whatsoever. I've always wondered if the GP's impromptu diagnosis was correct - I know that every PWD presents differently but from what I've read here on TP, there never seemed to be much similarity with mum's presentation of VasD and susequent deterioration. Mum died four years ago, but I find I'm still reading posts on TP and looking for answers (although I realise there may very well be none). Recently heard about NPH for the first time, which seemed to ring a few bells.
