FAST scale · stage 6 of 7
Stage 6 dementia: severe
Help is needed with dressing, washing or the toilet, and bladder or bowel control is lost.
What daily life looks like
Help is needed to put clothes on, then to wash or bathe, then with the mechanics of the toilet. Later in this stage, bladder control and then bowel control are lost. Agitation, suspicion, wandering and sleep disturbance are common, and the person may not always recognise family. The published scale splits this stage into five steps (6a to 6e) in that order.
| Step | What is now needed |
|---|---|
| 6a | Needs help putting clothes on |
| 6b | Needs help washing or bathing |
| 6c | Needs help with the toilet (flushing, wiping, adjusting clothes) |
| 6d | Bladder accidents happen |
| 6e | Bowel accidents happen |
What typically changes next
Within this stage, help usually extends from dressing to washing, toileting and continence, in that order. After it, speech fades to a few words.
Time typically reported at this stage: about 2.5 years (Reisberg 1988, Alzheimer's disease). An average across many people, never a prediction for one person.
What helps caregivers at this stage
- One task at a time, with a calm voice and the same sequence every day.
- Continence products, a bathroom routine on a schedule and a night light reduce accidents and distress.
- This is the stage where most families bring in help. Respite care, day programmes and home care are not giving up; they are how care lasts.
- Keep a care snapshot ready for any new carer: who they are, what calms them, what to avoid.
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.
