stage: 2
How long each stage of dementia lasts — and why the middle stages take longer than anyone warns you
The stages of dementia do not last the same amount of time for everyone. Early stages can last many years, while later stages are often shorter. Some people move through the stages slowly, and others decline more quickly because of age, overall health, or other medical problems. The middle stages are often the longest part of the process. The final stages are usually the most physically demanding and may last around one to three years. These are only general patterns, not exact rules.
