The Seven-A to Seven-F Substages, One by One

What are the FAST stage 7 substages?

Stage 7 is the last stage on the fast scale, and it is lettered because it covers a long descent through functions most people never think of as skills at all. The letters track speech first, then movement, then the postural reflexes that hold a body upright. They arrive in sequence, and the sequence is the same one for most people 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The FAST scale's seven major stages of functional decline in Alzheimer's dementia and its six lettered substages within stage 7 — speech narrowing, then loss of walking, sitting, smiling, and head control — and that FAST is the staging tool used in dementia hospice eligibility, with the relevant markers sitting at stage 7..

Stage 7 is the only stage on the scale carrying six lettered steps 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The FAST scale's seven major stages of functional decline in Alzheimer's dementia and its six lettered substages within stage 7 — speech narrowing, then loss of walking, sitting, smiling, and head control — and that FAST is the staging tool used in dementia hospice eligibility, with the relevant markers sitting at stage 7.. Stage 7 begins where fast stage 6 ended: the fast substages 6 letters walked down through dressing, bathing, and continence, and this stage picks up from there. The severe phase of the illness is described federally as one of full dependence, and these six letters are what full dependence looks like written down 2Ref 2National Institute on Aging (NIH) (2024).What Are the Signs of Alzheimer's Disease?.That the severe stage of Alzheimer's disease brings full dependence on others for care..

7a and 7b: when speech narrows to a few words, then to one

7a marks the point where a person's usable vocabulary has shrunk to a handful of intelligible words spread across an entire day. 7b marks the point where it has shrunk to one 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The FAST scale's seven major stages of functional decline in Alzheimer's dementia and its six lettered substages within stage 7 — speech narrowing, then loss of walking, sitting, smiling, and head control — and that FAST is the staging tool used in dementia hospice eligibility, with the relevant markers sitting at stage 7.. This is measured over an ordinary day rather than a single conversation, because speech at this stage comes and goes with fatigue, pain, and time of day.

Which words survive is unpredictable. Sometimes it is a name. Sometimes a phrase from a job held forty years ago, or a swear word, or a line from a hymn. The word that remains is not a summary of the person and should not be read as one.

Communication does not end when speech does. Tone of voice carries after words stop. So does touch, and rhythm, and music learned early. Many families find that narrating what they are doing — I am going to lift your arm now, it is raining outside — works better than asking questions, because a question invites a performance the person can no longer give.

7c: the loss of walking, and why this letter carries weight

7c names the point at which walking is no longer possible without help 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The FAST scale's seven major stages of functional decline in Alzheimer's dementia and its six lettered substages within stage 7 — speech narrowing, then loss of walking, sitting, smiling, and head control — and that FAST is the staging tool used in dementia hospice eligibility, with the relevant markers sitting at stage 7.. Families hear this letter named more than any other, and the reason is administrative rather than medical: the FAST tool is the staging instrument used in dementia hospice eligibility, and the markers that matter there sit inside stage 7 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The FAST scale's seven major stages of functional decline in Alzheimer's dementia and its six lettered substages within stage 7 — speech narrowing, then loss of walking, sitting, smiling, and head control — and that FAST is the staging tool used in dementia hospice eligibility, with the relevant markers sitting at stage 7.. That is why fast 7c criteria get searched for by name.

What is worth understanding is what that conversation actually is. A stage letter is one input. A hospice team evaluates the whole picture — the stage, other medical events over the past year, weight, infections, hospital stays — and makes the determination itself. Nobody qualifies or fails to qualify because of a letter written on a page at home. Asking for an evaluation is a request any family can make, and the evaluation is what settles it.

The practical shock of FAST 7c is separate from all of that. A person who cannot walk changes the physics of a household: transfers become two-person jobs, a bed may need to move downstairs, falls stop happening on stairs and start happening at the edge of a chair, and skin that stays in one position needs looking at every day.

7d, 7e, and 7f: sitting, smiling, and holding the head up

These three are the hardest letters to read, because none of them describes a skill anyone remembers learning. 7d is the loss of sitting up without support. 7e is the loss of the smile. 7f is the loss of the ability to hold the head up unaided 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The FAST scale's seven major stages of functional decline in Alzheimer's dementia and its six lettered substages within stage 7 — speech narrowing, then loss of walking, sitting, smiling, and head control — and that FAST is the staging tool used in dementia hospice eligibility, with the relevant markers sitting at stage 7.. They are among the earliest things a human body does and among the last things this illness takes.

7e is the one that undoes people. A parent who has not spoken in a year but still smiles when a grandchild comes in is still visibly answering; when the smile goes, the answer appears to stop. It is worth being precise about what the scale actually recorded. It recorded the movement of a face. It did not measure what was felt behind it, and it was never built to.

By 7f, care is entirely about position, comfort, mouth, and skin. The letters have stopped describing anything the person can do and started describing what the body can still hold.

What care looks like through stage 7

Full dependence, in the plain federal phrase 2Ref 2National Institute on Aging (NIH) (2024).What Are the Signs of Alzheimer's Disease?.That the severe stage of Alzheimer's disease brings full dependence on others for care.. Everything that keeps a body comfortable is now provided by somebody else: feeding, drinking, positioning, mouth care, skin care, bowels and bladder. The work is unglamorous, constant, and it is genuinely skilled — which is the argument for getting trained help rather than absorbing all of it privately.

• Eating and swallowing change. Meals slow down, coughing at the table appears, and food may be held in the mouth. Texture, pace, and upright positioning are the levers, and which ones to use is a conversation with a clinician or a speech therapist rather than something to work out alone.
• Mouth care matters more than it sounds. A dry, sore mouth is a common source of distress that cannot be reported.
• Pain shows up as behaviour. Grimacing on being moved, guarding a limb, new restlessness, or a change in breathing are how pain speaks when words are gone. All of them are worth reporting rather than interpreting at home.
• Position gets changed on a schedule, not when someone looks uncomfortable, because discomfort can no longer be announced.

Reading a stage 7 letter without over-reading it

Every letter in this stage measures output — words produced, movements performed, a face that moves or does not. None of them measures awareness, hearing, or feeling. Dementia is defined as a loss of cognitive function severe enough to interfere with daily life, ranging from mild to severe 3Ref 3National Institute on Aging (NIH) (2022).What Is Dementia? Symptoms, Types, and Diagnosis.That dementia is a loss of cognitive function severe enough to interfere with daily life, ranging from mild to severe., and even that definition is about function rather than about interior life.

The cognitive counterpart to this tool — the Global Deterioration Scale, or Reisberg staging, published by the same research group in 1982 — stages by what is happening to the mind instead 4Ref 4Reisberg B, Ferris SH, de Leon MJ, Crook T (1982).The Global Deterioration Scale for assessment of primary degenerative dementia.The existence and clinical origin of the seven-stage Global Deterioration Scale, published in 1982 by the same research group, as a cognitive staging framework for primary degenerative dementia.. At this end of the illness it faces the same wall from the other direction: the mind has become almost impossible to observe from outside.

The honest position is uncertainty, and uncertainty argues for continuing to talk, touch, and play the music — not for stopping. A letter recorded during pneumonia, after a fall, or a week after a hospital stay is also a snapshot rather than a stage; function that drops in days often has a cause worth finding.

Where stage 7 care happens, and how to look at a place

It happens at home with paid help, in a nursing home, in a dementia special-care unit, or in any of those with hospice working alongside. Federal guidance on choosing a long-term care setting says to assess current and future service needs — naming memory and dementia special units and hospice explicitly — to use the Eldercare Locator and Medicare's Care Compare, and to visit before deciding 5Ref 5National Institute on Aging (NIH) (2023).How To Choose a Nursing Home or Other Long-Term Care Facility.Federal guidance to assess current and future service needs — including memory and dementia special care units and hospice — to use the Eldercare Locator and Medicare's Care Compare, and to visit before deciding..

Medicare also publishes the questions to ask on that visit, covering rooms, activities, safety, staff, and dementia care 6Ref 6Centers for Medicare & Medicaid Services (2022).Questions to Ask When You Visit a Nursing Home (Nursing home checklist).That Medicare publishes an official visit checklist covering rooms, activities, safety, staff, and dementia care for families touring a nursing home.. Reading memory care criteria on a brochure is not the same exercise as walking a hallway. A few things are worth watching for at stage 7 in particular, and none of them appear in marketing material:

• Is anyone speaking to the residents who cannot answer, or only to the ones who can?
• How are residents who cannot walk positioned — upright and supported, or slumped?
• Is mouth care visibly happening, or only mentioned?
• Visit in the late afternoon rather than mid-morning, and go back a second time unannounced.

What the stage 7 letters do not tell you

They do not tell you how long. The scale records what has been lost and makes no claim about the interval to the next loss, and at this stage the interval is influenced far more by infections, swallowing, and other illnesses than by the dementia itself. Any specific timeline attached to a specific person is being invented somewhere between the source and the reader.

They also do not settle dementia hospice eligibility on their own. The hospice LCD dementia guidance is written around fast stage 7 markers, but a letter is a starting point for the conversation about dementia and hospice, not the end of one 1Ref 1Reisberg B (1988).Functional Assessment Staging (FAST).The FAST scale's seven major stages of functional decline in Alzheimer's dementia and its six lettered substages within stage 7 — speech narrowing, then loss of walking, sitting, smiling, and head control — and that FAST is the staging tool used in dementia hospice eligibility, with the relevant markers sitting at stage 7..

And they do not measure the family. There is no letter for the daughter who has not slept properly in two years. That part is not on the scale, which is precisely why it gets left out of the plan — and why hospice teams, respite programs, and support groups exist as a separate line item rather than an afterthought.
