The Stages of Alzheimer's Disease
Most doctors identify three main stages of Alzheimer's disease -- mild, moderate, and severe. Because each stage of dementia can last for several years or more, it can also be helpful to understand whether your loved one seems to be in the early, middle, or late part of each stage. Changes in memory and other thinking skills are the most reliable way to track someone's progression through dementia, but other symptoms also help to indicate the stage.

Early: You'll likely first notice an occasional repetition of stories, ideas, and questions -- or notice that appointments and errands go forgotten.
Mid: Deteriorating immediate memory loss causes word-for-word repetition of comments and questions to become more noticeable and more frequent, though it may not happen every day.
Late: The same stories are now repeated word for word at least several times a day; it's noticeable by strangers as well as family but doesn't yet happen continually.
Early: Stories and questions are repeated on very short loops, within minutes, continuously throughout the day.
Mid: As recent memory erodes, your loved one will begin asking questions like, "Where are we?" or "Why are we here?" or "What am I supposed to be doing?"
Late: Your loved one now views distant memories as recent (such as a deceased parent being referred to as alive) and sometimes can't accurately identify friends and some family members.
Early: Even distant memories are harder to recall and are no longer mentioned; your loved one may not recognize close family or know names.
Late: Your loved one is unlikely to speak more than a few words a day, can no longer sit up, and seems to stare right through you.
