How is transient ischaemic attack treated?

A transient ischaemic attack causes stroke-like symptoms that resolve, such as weakness on one side, slurred speech or numbness and tingling. Even when symptoms stop, the event needs prompt medical assessment because the underlying blood-vessel or heart problem may remain.

Clinicians may check blood pressure, heart rhythm, blood vessels and other stroke risk factors. Treatment can include blood-pressure medication, statin therapy or another medicine chosen for the cause. Atrial fibrillation may require a different blood-thinning approach, so do not start or stop medicines without medical advice.

If you have had symptoms that could be a transient ischaemic attack, seek same-day emergency assessment even if you now feel normal. Note when the symptoms began, which body parts were affected, how long they lasted and any medicines you take. Bring this information to the clinical team.

Follow the prevention plan, take prescribed medicines consistently, attend follow-up appointments and work with clinicians on blood pressure, cholesterol, smoking, activity and other modifiable risks.

Call emergency services immediately for new or returning facial drooping, weakness on one side, slurred speech, sudden loss of balance, vision change or severe headache. Do not drive yourself, and do not wait to see whether the symptoms settle.

Ask what caused the event, which tests are needed, how each medicine lowers risk, what to do if a dose is missed, and which warning signs require an emergency call.
