Advanced dementia

The term advanced dementia is used in these pages to refer to individuals whose cognition has deteriorated to a level where they are dependent on others for assistance and are no longer able to make decisions regarding their care independently.  While case conferencing may be useful in making shared decisions about care for people regardless of dementia status and stage, it takes on special importance for people with advanced dementia because of the need for others to make decisions on their behalf and the clinical decline towards death expected at this stage.

Advanced dementia as it is used on this website approximates to ‘severe’ dementia (stage 7) on common assessment tools such as the Global Deterioration Scale1 and Functional Assessment Staging Tool2. Elsewhere, advanced dementia is also referred to as ‘late-stage’ or ‘end-stage’ dementia.
