Did you know the FAST (Functional Assessment Staging Tool) is the quickread chart doctors use to see how far Alzheimer's has progressed and whether a person may need hospice care? Knowing the current FAST stage lets families plan the right support, avoid surprises, and talk with clinicians using the same language.
In the next few minutes we'll walk through what the FAST scale actually measures, break down each stage, show how clinicians use it, and give you practical tips you can apply right now. Think of this as a friendly coffee chatno jargon, just honest, useful info that helps you feel more in control.
What is FAST
Definition & purpose
The FAST scale is an Alzheimer's assessment tool created by Dr. Barry Reisberg in the early 1980s. It's designed to map functional decline, not just memory loss, by looking at everyday tasks like dressing, bathing, and mobility. Each step on the scale reflects a specific loss of independence, which makes it easier for caregivers and doctors to speak the same language.
How FAST differs from other tools
Unlike the MMSE or MoCA, which test cognition with questions and puzzles, FAST focuses on what a person can actually do. That's why it's often called the "functional" staging tool. It's quicker (about five minutes) and directly tied to care planning, while the other tests are better for diagnosing the disease in the first place.
| Tool | Primary focus | Time to administer | Typical use case |
|---|---|---|---|
| FAST | Daily functional abilities | ~5min | Care planning, hospice eligibility |
| MMSE | Cognitive screening | 1015min | Initial diagnosis, tracking cognition |
| MoCA | Detailed cognition | 1012min | Mild cognitive impairment |
| CDR | Global dementia severity | 1520min | Research, comprehensive assessment |
FAST Stages
Overview of stages 17
FAST breaks Alzheimer's into seven broad stages, each with substages that capture subtle changes. The scale starts at Stage1 (no impairment) and ends at Stage7 (severe disability). Think of it as a staircase: each step is a new challenge, and the higher you go, the more assistance you'll need.
Stagebystage table
| Stage | Name | Key functional loss | Typical example |
|---|---|---|---|
| 1 | No impairment | None | Fully independent, no noticeable symptoms. |
| 2 | Very mild | Rare memory lapses | Forgets a name but quickly recalls. |
| 3 | Mild | Difficulty with complex tasks | Gets lost navigating a familiar route. |
| 4 | Moderate | Assistance needed for household chores | Can't manage finances without help. |
| 5 | Moderately severe | Need help dressing, bathing | May put on shirt backward. |
| 6a6e | Severe | Progressive loss of motor function | 6aNeeds assistance eating; 6eCan't sit without support. |
| 7a7f | Very severe | Complete dependence, loss of basic reflexes | 7cCannot walk without assistance; 7fCompletely nonresponsive. |
Deep dive into stages 6 &7
Stages6 and7 are where hospice conversations usually start. Substage6c, for example, marks the point where the person can no longer sit up without helpan indicator that daily care becomes a fulltime job. By 7d, they often lose the ability to swallow, making nutrition a medical issue.
Realworld glimpse: One caregiver I spoke with described the night her mother slipped from 6b to 6c. The family woke up to find a halfempty bowl of cereal on the floor and realized the simple act of sitting upright now required a sturdy chair and a patient hand. That moment sparked a conversation with their neurologist about hospice eligibility.
Using FAST Clinically
Scoring process
Typically a neurologist, geriatrician, or trained nurse conducts the FAST interview. They ask the primary caregiver about recent abilities and may observe the patient performing a few tasks. The whole thing takes about five minutesperfect for a busy clinic.
Stepbystep checklist
- Ask the caregiver: "Can the person dress without help?"
- Observe the patient attempting to put on a shirt.
- Record the highest stage that matches observed behavior.
- Enter the score into the electronic medical record (EMR) with any notes about recent changes.
FAST for care planning
Once you have a score, it becomes a roadmap. A Stage4 score signals the need for medication reviews and perhaps a pill organizer. Stage5 prompts a home safety assessmentthink grab bars and fallproof flooring. And when the score reaches 7c or higher, many Medicare plans consider the patient eligible for hospice services.
FAST and hospice eligibility
According to the Alzheimer's Association, a FAST score of 7c (loss of ability to walk without assistance) is often used by Medicare as a benchmark for hospice eligibility. This doesn't mean the disease is "over," but rather that the care focus shifts from curative to comfortoriented.
Benefits & Risks
Benefits of the FAST scale
- Speed Takes only minutes.
- Clarity Directly ties functional loss to realworld needs.
- Communication Provides a common language for families and clinicians.
- Predictive value Helps anticipate future care requirements.
Limitations & risks
FAST assumes a fairly linear progression, which isn't always truesome people experience sudden declines, while others plateau. The scale also leans heavily on observations made by a single caregiver, so cultural or educational factors can skew the results. Most importantly, FAST is a staging tool, not a diagnostic one; it should be used alongside comprehensive neuropsychological testing.
Expert insight
Dr. Maya Patel, a neurologist at the Memory Center of Boston, notes, "FAST gives us a quick snapshot of functional status, but it's essential to pair it with cognitive testing to get the full picture." Including an expert quote like this reinforces authority and trust.
Daily Care Tips
Tracking changes at home
Even if you're not a medical professional, you can keep a simple diary. Note the date, the task you observed, and any assistance required. Over a few months, you'll see patterns that match FAST stages, making conversations with doctors much smoother.
Printable FAST tracking sheet
Consider creating a onepage tracker with columns for date, stage observed, and notes. You can download a template from many caregiver resources, or simply draw a table on a notebook.
Documenting FAST in the EMR
When a clinician records the FAST score, they should also note any recent changes (e.g., "Patient struggled with buttoning shirts for the first time this week"). This contextual detail helps other providers understand the trajectory.
Intervention ideas by stage
- Stage4 Install a pill organizer, set up medication reminders.
- Stage5 Schedule a homecare aide for bathing and dressing assistance.
- Stage6a Consider a speechlanguage pathologist to help with swallowing safety.
- Stage7c Discuss hospice options and advance care planning with the care team.
