Here is an excellent graphic explaining the stages of Alzheimer's. I post this just for general information for those who are new to understanding this disease. The disease affects everyone differently in appearance and order of symptoms, time of progression and when the intial diagnosis is made. So don't use this as a explicit and exact roadmap to the disease. Use this as information to help you understand what is happening with you. Example I see evidence of SOME of the first three stages in my own life.
