Stages of AD
The Stages of Alzheimer’s Disease
The recorded progress of Alzheimer’s disease through different functional stages can act as a
guide for caregivers to look after patients that have Alzheimer’s disease. Dr. Reisberg developed

progressive loss of functional abilities.
The 7 Different Stages are –
1. At this stage, you are a normal adult and have a perfect memory and functional ability –
no apparent symptoms or signs.

2. At the next stage, they show certain disabilities in their normal functioning, like being
unable to recollect known names of family members or places. This is often attributed to
be a normal characteristic of old age.
3. The third stage gives a clear indication of A.D. setting in. They are unable to locate their
