Recognize sudden stroke symptoms and understand why emergency medical care cannot wait.
Recognize sudden changes
Stroke occurs when blood flow to part of the brain is disrupted or bleeding occurs. Sudden facial drooping, arm weakness or speech difficulty are key warning signs. Other signs may include sudden visual changes, severe imbalance or an unusual severe headache.
Remember FAST
Face: does one side droop? Arms: is one arm weak? Speech: is it slurred or difficult? Time: call emergency services immediately. Note the last time the person was known to be normal.
Why hospital care is urgent
Clinicians must use emergency evaluation and brain imaging to identify stroke type. Some treatments are effective only for selected people and within specific clinical and imaging windows. Do not give food, drink or medication unless directed by emergency professionals.
Prevention and follow-up
Managing blood pressure, diabetes, smoking, cholesterol and certain heart conditions may reduce risk. Symptoms that disappear after a few minutes can still represent a transient ischemic attack and need emergency assessment.
Not all strokes look the same
A person can experience sudden loss of balance or vision without dramatic facial drooping. Sudden onset matters: do not dismiss unexplained neurological change simply because the FAST signs are incomplete.
Help the emergency team
Provide the time the person was last known well, known medications such as blood thinners and any relevant history. Do not delay calling an ambulance while checking the internet, trying home remedies or waiting for symptoms to disappear.
