I'm trying to contact, my partner who can give you more information I do remember her saying that he was diagnosed with vascular dementia. Even though he appears to know what's going on, he is often confused and cannot remember things.
My partner replied. He has vascular dementia. She read that in a report and it was highlighted, but didn't state it was extreme. This was some months back. Looking at the symptoms of vascular dementia, he has memory loss in terms of conversations and he is on medication for depression. He says he has heard his door bell ring very late at night but there's no certainty that this happened. He is also incontinent but we're not sure if this is related to this or another illness.
