FAST Scale For Dementia: Geriatric Clinician Explains

The functional assessment staging tool (FAST) is a crucial tool used to assess the functional status of individuals with Alzheimer's Disease, a type of dementia.

Developed by Dr. Barry Reisberg in 1982, the FAST scale provides a comprehensive evaluation of functional abilities in patients with all forms of dementia, aiding in the planning of appropriate care.

By measuring physical and language abilities, as well as functional activities, the Fast Score allows for an objective assessment of functional and cognitive decline and the tracking of changes over time.

Its applications extend to various care settings, including hospice and home care, where it assists in tailoring care plans to individual patient needs.

As we explore the significance and implications of the Fast Score for Dementia, we will uncover how this tool empowers caregivers and enhances the quality of life for those living with dementia.

Overview of the FAST Scale for dementia

The FAST scale, developed by Dr. Reisberg in 1982, is a practical and widely utilized tool for assessing functional decline in all forms of dementia.

It serves as a functional assessment staging tool that allows healthcare professionals to monitor the progression of dementia and understand the functional, physical, and language abilities of individuals.

The scale consists of seven stages that represent different levels of cognitive decline and functional impairment.

The FAST scale is particularly useful in hospice care settings, where it can help determine the appropriate level of care for individuals with advanced dementia.

It consists of seven stages that indicate the level of cognitive decline, ranging from normal functioning (stages 1 and 2) to severe dementia (stage 7). 

The FAST scale is used by clinicians and caregivers to assess the ability of individuals to perform daily activities and communicate effectively.

By regularly using the FAST scale, healthcare professionals can monitor the progression of dementia and track the effectiveness of treatment over time.

This information is crucial for developing personalized care plans and setting realistic goals for dementia care.

In addition, the FAST scale plays a vital role in determining the need for hospice care. 

A person with dementia classified as stage 7 on the FAST scale has lost the ability to speak coherently, saying only a single intelligible word, or has lost the ability to perform simple activities of daily living. 

At this juncture, they are in the terminal stage of dementia and may benefit from hospice care.

Hospice care provides tailored support for individuals with a life expectancy of around 6 months or less and helps improve their quality of life. 

Stages of Functional Decline in Alzheimer's Disease

The table below details the 7 stages of the FAST scale for dementia:

The 7 FAST Stages Of Dementia

FAST Score	Dementia Stage	Description
1	No Cognitive Decline	Cognitive and functional ability is normal. No observable signs of dementia.
2	Very Mild Cognitive Decline	Slight cognitive changes; mild forgetfulness and word-finding difficulty.
3	Mild Cognitive Decline	Changes become noticeable; memory issues observed by others; difficulty in social/work settings.
4	Moderate Cognitive Decline	Significant memory loss; reduced problem-solving ability and attention; clear cognitive deficits.
5	Moderately Severe Cognitive Decline	Marked decline; confusion about time and place; increasing functional impairment.
6	Severe Cognitive Decline (a–e)	Severe impairment; difficulty recognizing loved ones; personality changes.
6a	Severe Cognitive Decline	Difficulty dressing; inappropriate clothing for weather; problems with buttons/zippers.
6b	Severe Cognitive Decline	Difficulty bathing; unable to manage water temperature or use fixtures properly.
6c	Severe Cognitive Decline	Difficulty with toileting; poor hygiene or forgetting steps.
6d	Severe Cognitive Decline	Urinary incontinence begins (occasional or frequent).
6e	Severe Cognitive Decline	Fecal incontinence begins (occasional or frequent).
7	Very Severe Cognitive Decline (a–f)	Very severe decline in cognitive and physical abilities.
7a	Very Severe Cognitive Decline	Speech limited to a few understandable words.
7b	Very Severe Cognitive Decline	Speech limited to a single word.
7c	Very Severe Cognitive Decline	Loss of ability to walk independently.
7d	Very Severe Cognitive Decline	Unable to sit without assistance.
7e	Very Severe Cognitive Decline	Loss of ability to smile.
7f	Very Severe Cognitive Decline	Unable to hold head up.

My Clinical Take

During my many years of working with patients and caregivers struggling with dementia, I have come to understand that the progression of dementia is very specific to the individual.

Some people will hold steady at a particular stage for a few years, while others will progress through the stages within a year or two.

There are so many other contributing factors that determine an individual's progression - medications, other chronic or acute medical problems, access to healthcare, knowledge and education about dementia, access to social interaction, etc.

Overmedication or polypharmacy is the 5th leading cause of death in the U.S. and can cause great harm to people with dementia.

A seemingly benign OTC medication such as Benadryl can cause such a severe effect in a person with dementia that it could send them to the hospital.

Or, paroxetine, a common antidepressant, is quite possibly the worst medication from the SSRI class to give to the older adult.

Because of the possibility of these factors potentially worsening the progression of dementia, it is imperative that a multi-disciplinary approach is adopted when caring for a loved one living with this disease.

Encourage communication between your loved one's primary doctor, other specialists such as neurologists, psychiatrists, pharmacists, etc.

If one is available near you, I recommend having your loved get established as a patient with a geriatrician.

In my opinion, they are the best-trained doctors to manage complex dementia and geriatric-related issues.

Conclusion

In conclusion, the Fast Score for Dementia is a valuable tool for assessing functional abilities in individuals with dementia.

It provides objective measurements of cognitive decline and is widely used in various settings, including hospice and home care, to tailor care plans based on individual patient needs.

By tracking changes over time, it improves the quality of life for patients and supports well-informed decision-making by caregivers.
