Deb.. my sympathies on losing your Mom to this disease. It is a difficult journey.
Yes, there are actually many different types of dementia. Each is different and why it is so important to get a correct diagnosis. We have had post from those who have loved ones with Lewy Body. My Mom has Alzheimer's and my father had Vascular Dementia. They were very different. I will say that my Dad also had delusions and hallucinations... which can happen with Vascular Dementia as well. So the best thing to do is get the best diagnosis possible. Thanks for the heads up
