According to Professor Barry Reisberg’s scale, dementia progresses through 7 stages:

 

1. Disease imperceptible

2. Mild memory problems

3. Disease becomes noticeable

4. Strong decline in short-term memory

5. Need help with simple things

6. Character change and strong need for help

7. 24-hour care needed

 

The use of the Maziance dementia clock is useful in the first 5 stages.
