Commonly asked questions

The FAST Scale is a tool developed by Dr. Barry Reisberg to assess the functional decline in patients with dementia, particularly those with Alzheimer's disease. It evaluates cognitive and functional abilities across seven stages of dementia.

Life expectancy varies depending on the stage of dementia. Patients in Stage 7 of the FAST Scale, indicating severe dementia, may have a life expectancy of approximately 1.5 to 2 years.

A patient with a FAST score of 7 or above, which includes severe dementia and significant functional decline (e.g., loss of speech and mobility), typically qualifies for hospice care, as it indicates the late stages of dementia.
