Hi, Jeenie--
Just wanted to offer you some support and a cyberhug.
It's scary, just starting out on this journey, but I want to give you a bit of encouragement and let you know that, at least in my opinion, it is much EASIER to deal with when you actually have a diagnosis and an understanding of what it is that "isn't quite right."
My husband has Parkinson's disease and some vascular issues. His issues come and go, and this was one of the most difficult parts to adjust to--the variability and unpredictability of his personality.
I think you're on the right track and the professionals will be able to give you more information at your appointment. Then you can do some online research and learn more from Posters here, as well as Post specific questions/concerns.
So many have walked this path before & are kind enough to check in here periodically and answer questions.
Just want to let you know you're in a welcoming place and we wish you and your husband well.
I'm sure others with specific ideas/experiences related to vascular dementia will be along to share some hope and help soon.

P.S. One important tip: ALWAYS take a notebook and pen to the appointements and make notes of what is said. You won't remember it all, unless you write it down. I even write down my hubby's blood pressure readings, weight, & temperature when they take it, just for the record. Don't be afraid to ask the doctor to spell the diagnosis, condition, or a test he's ordering if you don't know how to spell it; in my experience, they're willing to explain to patients who express interest & concern.
