My husband was diagnosed with vascular a year ago, although the Dementia doctor now says he has probably had it for at least 6/7 years. After going through different periods e.g. Nastiness etc. and suffering a major bleed to brain.
Depends what part of the brain is affected. Unfortunately my OH has frontal so its all about personality and apathy. It can be really hard sometimes to know how much is dementia and how much it is the dementia high lightning his normal personality, which has never been easy.
He can still was and dress even with loss of one arm from the stroke. Get himself a drink, food etc. Still knows who everyone is and what's going on. But you can't reason with him because he will always be right, no matter what! Although it has been part of his personality before the stroke or dementia so its hard to know if anything's changed there.
The hardest part of all this has been his nastiness towards me. (one one else) The only time he speaks is if he wants something.
The 'steps' have been more like phases he goes through e.g. Went through phase of violence a few years ago but luckily it stopped. But I think it could be more to do with frustration because he can't do what he used to since his stroke.
It's really hard to tell you how vascular will affect someone as I said its different, depending on what part of the brain is affected.
