Reading the FAST Scale, Stage by Stage
SaveA one-page staging tool from 1988 still shapes how dementia hospice eligibility is documented. Here is what each FAST stage looks like in daily life, what the lettered substages of stages 6 and 7 mean, why hospice paperwork cites 7A and 7C so often, and why the number alone never settles a six-month prognosis.

What is the FAST scale?
The FAST scale — the Functional Assessment Staging Tool, published by Barry Reisberg in 1988 — describes Alzheimer's-type dementia by what a person can still do, in seven stages running from normal function to the loss of speech, walking, and head control 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The seven FAST stages, their ordinal sequence, the lettered substages of stages 6 and 7, and the stage-7 markers (speech loss, loss of ambulation, sitting, smiling, and head control) in Alzheimer's-type dementia.. Clinicians sometimes call it Reisberg staging. It is not a memory test. It is a map of everyday abilities: holding a job, managing money, choosing clothes, dressing, bathing, walking, speaking.
That focus on function is what makes FAST usable late in the disease. In advanced dementia, conversation fades and formal testing stops being possible, but what a person can do in a day remains observable at the bedside. A nurse who has watched someone eat, transfer, and respond can assign a stage without asking a single test question. That is also why the tool appears so often in hospice paperwork.
What are the seven stages, in plain language?
FAST runs from stage 1, no difficulty at all, to stage 7, the near-total loss of speech and movement 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The seven FAST stages, their ordinal sequence, the lettered substages of stages 6 and 7, and the stage-7 markers (speech loss, loss of ambulation, sitting, smiling, and head control) in Alzheimer's-type dementia.. The early stages describe changes only the person notices; the middle stages describe lost independence in complex tasks; the late stages describe the loss of basics — dressing, bathing, continence, and finally words and walking.
| Stage | What it looks like in daily life |
|---|---|
| 1 | No difficulties, either felt by the person or seen by others |
| 2 | The person feels forgetful — misplacing things, losing words — but others see no problem |
| 3 | Difficulty becomes visible to others: slipping performance at work, trouble finding the way to new places |
| 4 | Complex tasks need help — handling finances, planning a dinner for guests |
| 5 | Choosing clothing appropriate to the day or season needs help |
| 6 | The basics need help, in a characteristic order: dressing, bathing, the mechanics of toileting, then urinary and bowel control |
| 7 | Speech shrinks to a handful of words and then to none; walking, sitting up, smiling, and holding the head up are lost, roughly in that order |
The staging assumes abilities are lost in this sequence 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The seven FAST stages, their ordinal sequence, the lettered substages of stages 6 and 7, and the stage-7 markers (speech loss, loss of ambulation, sitting, smiling, and head control) in Alzheimer's-type dementia.. When someone loses skills out of the expected order — walking before speech, say — clinicians weigh whether something other than typical Alzheimer's progression is at work.
What do the lettered substages of stages 6 and 7 mean?
Stages 6 and 7 each break into lettered substages, and hospice documentation often cites the letter rather than the number alone 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The seven FAST stages, their ordinal sequence, the lettered substages of stages 6 and 7, and the stage-7 markers (speech loss, loss of ambulation, sitting, smiling, and head control) in Alzheimer's-type dementia.. Stage 6 walks through the loss of self-care: help needed with dressing (6a), then bathing (6b), then the mechanics of toileting (6c), then urinary incontinence (6d) and bowel incontinence (6e). Stage 7 walks through the loss of speech and movement: speech limited to roughly half a dozen intelligible words (7a), then to a single word (7b), loss of the ability to walk without assistance (7c), to sit up without assistance (7d), to smile (7e), and to hold the head up (7f).
Two substages carry particular weight in hospice conversations: 7a, because speech reduced to a few words is often the first stage-7 marker a clinician documents, and 7c, because losing the ability to walk marks the transition to full physical dependence. A chart note reading "FAST 7C" is shorthand for a person who is no longer walking, no longer meaningfully speaking, and dependent for all care.
Why does hospice care about stage 7?
Medicare's hospice guidance for dementia keys on stage-7 function. The Local Coverage Determination that Medicare contractors use to review hospice eligibility sets out disease-specific criteria supporting a prognosis of six months or less, and its dementia criteria look for FAST stage 7 function — the loss of meaningful speech and independent walking — usually alongside a complication such as recurrent infections, pressure injuries, or weight loss from eating difficulty 2Ref 2Centers for Medicare & Medicaid Services (Medicare Administrative Contractor LCD) (2023).Local Coverage Determination (LCD): Hospice - Determining Terminal Status (L33393).That Medicare's hospice LCD sets out disease-specific criteria supporting a six-month prognosis, including dementia criteria keyed to stage-7 function with complications, and that these thresholds are guidance in support of a physician's judgment rather than absolute cutoffs.. The stage is documentation, though, not a verdict: the same guidance is explicit that these thresholds support a physician's prognosis judgment rather than replace it 2Ref 2Centers for Medicare & Medicaid Services (Medicare Administrative Contractor LCD) (2023).Local Coverage Determination (LCD): Hospice - Determining Terminal Status (L33393).That Medicare's hospice LCD sets out disease-specific criteria supporting a six-month prognosis, including dementia criteria keyed to stage-7 function with complications, and that these thresholds are guidance in support of a physician's judgment rather than absolute cutoffs..
This is the honest shape of hospice eligibility for dementia. Physicians certify that six months or less is the expected course if the disease progresses normally, and the FAST stage is one of the strongest pieces of evidence they can point to. A person at stage 7a who has had aspiration pneumonia twice this year presents a very different certification than a person at 7a who is otherwise stable.
How common is dementia on hospice?
Very. In federal survey data, Alzheimer disease or another dementia is present in nearly half of the people using hospice services in the United States 3Ref 3National Center for Health Statistics (CDC) (2024).Overview of Post-acute and Long-term Care Providers and Services Users in the United States, 2020 (National Health Statistics Reports No. 208).That Alzheimer disease or other dementias are present in nearly half of hospice services users in the United States.. And in Medicare data for calendar year 2022, Alzheimer's, dementia, and other nervous-system disorders together made up the leading hospice diagnosis category, at roughly a quarter of diagnoses 4Ref 4National Alliance for Care at Home (formerly NHPCO) (2024).NHPCO Facts and Figures, 2024 Edition.That in CY2022 Alzheimer's, dementia, and other nervous-system disorders were the leading Medicare hospice diagnosis category, at roughly a quarter of diagnoses.. The overlap between dementia and hospice is not an edge case; it sits close to the center of what American hospice does.
That prevalence cuts both ways. It means hospice teams see advanced dementia every week and know its course well. It also means the FAST scale — a research instrument from 1988 — quietly became one of the most consequential documents in many families' dementia years, because a stage written in a chart can open or delay a family's access to hospice support at home.
What the FAST stage cannot tell a family
A FAST stage describes function today; it does not schedule anything. People can remain at stage 7 for a long time, decline can plateau, and two people at the same substage can follow very different courses. The stage supports a prognosis; it is not one.
It also cannot say what kind of care fits. Palliative care — symptom-focused support delivered alongside ongoing treatment — is available at any stage of a serious illness, while hospice is comfort-focused care for the final months, when the goal shifts away from treating the disease itself 5Ref 5National Institute on Aging (NIH) (2024).What Are Palliative Care and Hospice Care?.The distinction between palliative care, which is available at any stage of serious illness alongside treatment, and hospice, which is comfort-focused care near the end of life.. A family watching late-stage dementia is not choosing between "hospice now" and "nothing": there is a middle path earlier in the course, and it is worth asking the treating clinician which options are on the table at the current stage.
Bringing the stage to a conversation
Families can use the FAST framework without scoring anyone themselves. Useful questions for the next clinic visit: Which FAST stage is documented in the chart, and when was it last updated? What has changed since the last visit — words, walking, swallowing, weight? Has anything happened this year — pneumonia, a pressure injury, hospitalizations — that changes the six-month picture?
If the answers point toward stage 7 with complications, that is a reasonable moment to ask directly for a hospice evaluation — a conversation, not a commitment. And if the answer is "stage 6, and stable," the same conversation can turn to what support exists in the meantime, and to what the family should watch for that would change the answer.

When to call for help in advanced dementia
- —A sudden change in alertness over hours to a day — new unresponsiveness, or agitation and confusion far beyond the person's baseline — which can signal delirium from infection or a medication effect
- —Coughing, choking, or a wet, gurgling voice with every attempt at food or liquid
- —A fall followed by new pain when the person is moved, or a limb held at an odd angle
- —Fever together with a reddened pressure area, a wound, or foul-smelling urine
A sudden collapse, unresponsiveness, or serious trouble breathing warrants 911. For a person already enrolled in hospice, the hospice's 24-hour nurse line is the first call for everything short of that.
This article explains a staging tool for education. It is not medical advice, and no stage or score here can determine any individual's prognosis or eligibility. Decisions about hospice belong in a conversation with the treating clinicians, who can examine the person and the whole record.
