FAST scale · stage 7 of 7
Stage 7 dementia: very severe
Speech fades to a few words, then walking, sitting up, smiling and holding the head up need support.
What daily life looks like
Speech is limited to a handful of words, then one, then none. The person loses the ability to walk, then to sit up without support, then to smile, and finally to hold their head up. They need full care for eating, moving and comfort. The published scale splits this stage into six steps (7a to 7f).
| Step | What is now true |
|---|---|
| 7a | Speaks only a handful of words in a day |
| 7b | Speaks at most one clear word |
| 7c | Can no longer walk without being held |
| 7d | Can no longer sit up without support |
| 7e | No longer smiles |
| 7f | Can no longer hold their head up |
What typically changes next
Within this stage, speech goes first, then walking, sitting, smiling and head control. This stage is the longest reported, often 6 years or more.
Time typically reported at this stage: 6 years or more (Reisberg 1988, Alzheimer's disease). An average across many people, never a prediction for one person.
What helps caregivers at this stage
- Comfort is the goal: positioning, skin care, mouth care, warmth, pain checks, music and touch.
- Ask the care team about palliative and hospice support early; it is for comfort, not only for the last days.
- Your own grief is real while the person is still here. Carer groups and counselling exist for exactly this.
When to talk to a clinician
A sudden change, over days rather than months, is not a stage change. Confusion that appears quickly, new agitation, a fall or a change in eating or continence can be an infection, pain, a medication effect or dehydration, and those are treated. Bring your log and the date you last filled in the checklist.
