When to worry about slurred speech with stroke

A stroke can interrupt blood flow to areas that plan, produce, or understand language. Speech may sound slurred, words may be difficult to find, or the person may struggle to understand what is said. Look for facial drooping, arm or leg weakness, numbness, loss of balance, vision change, severe headache, or new confusion. These signs can occur together or separately, and the person may not recognise the change themselves.

Call emergency services immediately and say that a stroke may be happening. Note the time the person was last known to be speaking and moving normally. Keep them resting safely, reassure them, and gather their medicines and medical details if this can be done without delaying the call. Do not give food, drink, or medication unless instructed by emergency professionals, because swallowing may be affected. Do not drive them yourself if an ambulance is available.

Seek emergency help for any sudden slurred speech, particularly with facial asymmetry, weakness, numbness, difficulty walking, vision loss, confusion, or a severe unusual headache. Emergency assessment is still needed if the speech returns to normal, because a brief episode can be a warning of a more serious event. Do not wait for another symptom or for the person to sleep it off.

Ask which warning signs should prompt an immediate call in the future, what tests were performed, and how prescribed medicines should be taken. Discuss blood pressure, diabetes, heart rhythm, smoking, and other factors relevant to reducing future stroke risk. Ask how family members can recognise speech and movement changes quickly.
