Acute focal neurological deficit

Recognise possible stroke, establish onset and activate the local stroke pathway while checking important mimics.

PAUSE BEFORE USING

This is an educational summary, not a point-of-care protocol. Follow current local emergency and medicines guidance and seek senior/specialist support.

FICTIONAL SCENARIO

A fictional 73-year-old suddenly develops expressive dysphasia and right arm weakness during breakfast.

01 · RECOGNISE

Frame the danger first.

  • Sudden focal neurological deficit should trigger a stroke assessment and urgent pathway activation.
  • Establish the exact last-known-well time and premorbid function.
  • Check glucose promptly and consider seizure, migraine and other mimics without delaying stroke assessment.
02 · FIRST PRIORITIES

Act, escalate, reassess.

  1. Activate the local hyperacute stroke pathway and arrange urgent brain imaging as directed.
  2. Record onset/last-known-well time, neurological deficit, anticoagulant use and relevant contraindications.
  3. Keep the patient nil by mouth until an appropriate swallowing screen is completed.
  4. Seek immediate stroke-specialist decisions about reperfusion and subsequent management.
03 · ESCALATE NOW IF

Red flags that change pace.

  • Reduced consciousness, rapidly worsening deficit or airway compromise
  • Posterior-circulation features with deterioration
  • Severe headache, meningism or features suggesting intracranial haemorrhage
04 · COMMON ERRORS

What makes care less safe.

  • Missing posterior-circulation stroke because FAST is negative
  • Delaying referral while completing non-essential investigations
  • Giving oral food, fluid or medicines before swallow screening
05 · STRUCTURED HANDOVER

Say the concern plainly.

Possible acute stroke: last known well [time], deficit [brief description], glucose [result], anticoagulation [yes/no], baseline function [summary]. The stroke pathway is active and urgent specialist assessment is required.
