Recognising Stroke Symptoms for Student Nurses
Learn how to recognise sudden neurological changes that may indicate stroke and why rapid assessment, accurate timing and immediate escalation matter.
Think sudden neurological change
Stroke occurs when blood flow to part of the brain is disrupted. Presentation varies according to the area affected, so students should recognise both classic and less obvious neurological changes.
Facial weakness
One side of the face may appear weak or drooped, particularly when the patient smiles.
Arm or leg weakness
Sudden weakness, heaviness, numbness or loss of coordination may affect one side of the body.
Speech or language change
Speech may become slurred, words may be difficult to produce, or the patient may struggle to understand language.
A new neurological deficit developing abruptly should immediately raise concern and trigger urgent assessment.
Remember the FAST approach
Face
Has the face fallen on one side? Can the patient smile normally?
Arms
Can the patient raise both arms and keep them raised?
Speech
Is speech slurred, confused, unusual or difficult to understand?
Time
If stroke is suspected, urgent emergency assessment is required.
Other symptoms that may occur
Not every stroke presents with the classic FAST pattern. Other sudden neurological changes can also be important.
Visual disturbance
Sudden loss of vision, double vision or another significant visual change may occur.
Coordination problems
Sudden severe unsteadiness, loss of coordination or difficulty walking may be significant.
Numbness
Sudden altered sensation or numbness may affect the face, arm, leg or one side of the body.
Confusion
Sudden difficulty understanding, communicating or behaving normally may represent neurological change.
Dysphagia
Stroke can impair swallowing and increase the risk of aspiration.
Sudden severe headache
A sudden severe or unusual headache, particularly with neurological change, requires urgent assessment.
Establish when the patient was last known well
Timing can influence assessment and treatment decisions, making an accurate history particularly important.
When were symptoms noticed?
Record the time symptoms were first observed where this is known.
When was the patient last normal?
Establish when they were last known to be without the new neurological deficit.
Was the onset witnessed?
Witness information can help establish a clearer timeline.
Communicate the timing
Include symptom onset or last-known-well time when escalating.
Stroke recognition still sits within ABCDE
Airway
Assess airway patency and identify any immediate airway concern.
Breathing
Assess respiratory rate, breathing pattern, SpOâ‚‚ and oxygen therapy where applicable.
Circulation
Review pulse, blood pressure, perfusion and other relevant cardiovascular observations.
Disability
Assess consciousness, pupils, neurological change and blood glucose according to local practice.
Exposure
Look for other relevant clinical findings while preserving dignity and preventing avoidable delay.
Escalate immediately
Activate the appropriate local stroke or emergency pathway when acute stroke is suspected.
Remember blood glucose
Abnormal blood glucose can produce neurological symptoms and should be assessed promptly according to local acute stroke and emergency procedures.
Neurological change
Do not dismiss sudden weakness, confusion or altered consciousness.
Blood glucose
Include glucose in the assessment according to local clinical protocols.
Do not create delay
Essential bedside assessment should occur alongside urgent escalation rather than postponing it.
Putting stroke recognition into practice
Example
During morning observations, a patient who had been speaking normally earlier suddenly appears unable to move their left arm effectively.
Their smile appears asymmetrical and their speech has become slurred.
You recognise a possible acute neurological event, call for immediate assistance and begin an appropriate ABCDE assessment without delaying escalation.
You establish that the patient was last seen without these symptoms approximately 20 minutes earlier and communicate this clearly.
The important pattern is: sudden focal neurological change + known timing + immediate escalation.
Neurological warning signs that require urgent action
- New facial weakness or asymmetry.
- Sudden unilateral arm or leg weakness.
- New speech or language disturbance.
- Sudden significant visual disturbance.
- New severe loss of balance or coordination.
- Sudden reduced consciousness or significant confusion.
- Sudden severe headache with neurological abnormalities.
- New swallowing difficulty associated with neurological change.
- Any rapidly evolving focal neurological deficit.
What should you communicate?
- The exact neurological changes you have observed.
- Whether symptoms developed suddenly.
- The time symptoms were first noticed.
- The last-known-well time where available.
- FAST findings and any other neurological abnormalities.
- Level of consciousness.
- Current observations and NEWS2 where applicable.
- Blood glucose according to local practice.
- Relevant known history and medications where available.
Example escalation
“I'm concerned that Mrs Taylor may be having an acute stroke. She has developed new left-sided facial weakness, cannot maintain her left arm raised and her speech is now slurred. She was last seen without these symptoms at approximately 10:15.”
Clear description and accurate timing can be more useful than simply saying that the patient “looks neurological”.
Stroke recognition errors to avoid
- Waiting to see whether neurological symptoms resolve.
- Assuming stroke must cause reduced consciousness.
- Using FAST as a rule-out test rather than a recognition tool.
- Failing to establish symptom onset or last-known-well time.
- Forgetting to assess blood glucose according to local practice.
- Giving food or drink before swallowing safety has been appropriately assessed.
- Focusing on completing observations before calling for urgent help.
- Describing the patient as “confused” without explaining exactly what changed.
Recognise → assess → communicate → escalate
Spot sudden change
Recognise new facial, limb, speech, vision, balance or other neurological abnormalities.
FAST + ABCDE + timing
Assess systematically, establish when symptoms began and obtain essential bedside information without delaying escalation.
Act urgently
Clearly communicate the neurological deficit and activate the appropriate local stroke or emergency pathway.
Build confidence recognising neurological deterioration
Sudden changes in movement, speech, consciousness, behaviour and neurological function can provide some of the earliest clues that a patient needs urgent assessment.
