After scoring: open the scene pack, peer scores, and the matching pathway. Local reference — no HIS write.
- Who it is for
- Adults with suspected acute stroke when quantifying deficit and deciding reperfusion, or TIA when judging short-term risk.
- Who it is not for
- Do not use ABCD² to decide thrombolysis. No new stroke scale.
- Formula and variables
- NIHSS is the neurologic deficit; items stay as on this page. FAST-ED is a prehospital large-vessel screen. ABCD² is age, blood pressure, clinical features, duration, and diabetes, for TIA.
- Result → next step
- This scene links only to the three tools below: deficit and time window open the thrombolysis page. A positive large-vessel screen opens thrombectomy. Drugs after the acute phase open secondary prevention. Thrombolysis shows no number until weight, onset time, pregnancy, and recent anticoagulation are known. Anticoagulant-related intracranial bleeding goes to reversal and ICH management.No numeric dose until age, weight, renal function, and pregnancy are all known. Pregnancy is contraindication or caution only.Thrombectomy →

≥ 4 suggests anterior LVO amenable to thrombectomy.
When to use
[Pending update] Some thresholds, grades and management recommendations on this page that conflict with current guidelines or are unverified are temporarily hidden pending verification against the guideline text.
How it works
Facial palsy (0–1), arm weakness (0–2), speech (0–2), eye deviation (0–2), neglect (0–2); total 0–9. ≥ 4 suggests LVO.
Key points
- ≥ 4 suggests anterior LVO amenable to thrombectomy.
- At ≥ 4, sensitivity is 0.60 and specificity 0.89 (Lima 2016); a score < 4 does not rule out LVO.
- Derived from NIHSS items predictive of LVO.
- Use alongside vascular imaging and transfer protocols.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Facial palsy | Absent (0) |
|---|---|
| Arm weakness | Drift (1) |
| Speech changes | Mild–moderate (1) |
| Eye deviation | Partial (1) |
| Denial/neglect | One modality (1) |

- Interpretation：≥ 4 — likely large-vessel occlusion.
- Lima 2016：sensitivity 0.60, specificity 0.89

|---|---|
| Arm weakness | No drift (0) |
| Speech changes | Absent (0) |
| Eye deviation | Absent (0) |
| Denial/neglect | Absent (0) |

FAQ
Frequently asked questions
- Does FAST-ED Score (LVO Screen) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is FAST-ED Score (LVO Screen) calculated in practice? Can you show a worked example?
- Inputs: Facial palsy Absent (0), Arm weakness Drift (1), Speech changes Mild–moderate (1), Eye deviation Partial (1), Denial/neglect One modality (1) → Result: FAST-ED 4 /9（Interpretation: ≥ 4 — likely large-vessel occlusion., Lima 2016: sensitivity 0.60, specificity 0.89） Inputs: Facial palsy Absent (0), Arm weakness No drift (0), Speech changes Absent (0), Eye deviation Absent (0), Denial/neglect Absent (0) → Result: FAST-ED 0 /9（Interpretation: < 4 — lower likelihood of LVO., Lima 2016: sensitivity 0.60, specificity 0.89）
