Stages for the Body

I wanted to understand what each of the stages on a person's body seem to entail. I will dig deeper into these as my own research continues but on the most basic level...simply put the stages include:

            Early Signs

                     Mild forgetfulness interferes with daily activities
                     Trouble remembering events or activities
                     Trouble remembering names of familiar people and things
                     Loss of ability to solve simple math problems
         Mild to Moderate Stages
                     Loss of ability to do simple tasks like brushing teeth and combing hair
                     Failure to recognize familiar people and places
                     Trouble speaking, understanding, reading and/or writing
                     May become anxious, aggressive, wander away from home
                     Become increasingly unaware of their limitations
         Late Stages
                     Greater confusion and disorientation
                     Complete dependency on others
                     Physical health deteriorates due to inactivity
                     Death is usually due to pneumonia or other infections
