The 7 stages of Dementia, as described by the Global Deterioration Scale, are as follows:

1. No Cognitive Decline: In this stage, the individual shows no signs of cognitive decline and functions normally.
2. Very Mild Cognitive Decline: In this stage, the individual may have some trouble remembering recent events, but these lapses are not noticeable to others.
3. Mild Cognitive Decline: In this stage, the individual begins to have noticeable memory problems, but is still able to live independently.
4. Moderate Cognitive Decline: In this stage, the individual’s memory and ability to think clearly become more impaired. They may struggle with everyday activities and require assistance with certain tasks.
5. Moderately Severe Cognitive Decline: In this stage, the individual’s ability to communicate and understand becomes significantly impaired. They may have trouble recognizing familiar faces and have difficulty with activities of daily living.
6. Severe Cognitive Decline: In this stage, the individual becomes increasingly disoriented and may have trouble recognizing their own surroundings. They may also experience significant changes in behavior and mood.
7. Very Severe Cognitive Decline: In this stage, the individual becomes increasingly dependent on others for their care and may require 24-hour supervision. They may also experience significant changes in behavior and physical abilities.

It’s important to note that each individual’s journey through dementia is unique, and the pace of progression can vary greatly. The stages described above are meant to provide a general understanding of the typical progression of dementia, but they are not a set timeline.
