How common is slurred speech in a transient ischaemic attack?

A transient ischaemic attack briefly disrupts blood flow to part of the brain. Speech may sound slurred, words may be hard to find, or understanding may become difficult. Weakness or numbness on one side, facial drooping, vision disturbance, dizziness, or poor balance can occur with it. Symptoms can disappear before assessment, but that does not make the event harmless. A clinician must assess whether the episode was a transient attack or an ongoing stroke.

Call emergency services immediately for sudden slurred speech, even if the person is speaking normally again. Note when symptoms started and when they stopped, and list medicines and relevant medical conditions for the clinical team. Keep the person supervised and do not offer food, drink, or medicine unless instructed. Do not drive to a hospital if emergency transport is available.

Emergency assessment is needed for any sudden speech disturbance, including a brief episode. Call again immediately if symptoms return or if there is new weakness, facial drooping, confusion, severe headache, vision loss, or trouble walking. A transient attack can be a warning of a later stroke, so waiting for a routine appointment is unsafe.

Ask what may have caused the episode, which tests and prevention steps are needed, how to take prescribed medicines, and which symptoms require another emergency call.
