I am so confused and frustrated. That's why I'm here. My Dad was diagnosed with "dementia" over 3 years ago. Although I am an intelligent human being, would someone please help me understand the difference between using the word "dementia" as a diagnosis versus using the term "Alzheimer's"? My dear dad has all the symptoms listed for both. I hope you'll forgive my ignorance, but I haven't seen anything that clarifies this for me. I am "here2learn" - that's HERE TO LEARN. Please help and bless you for doing so!
