Summary

• A stroke occurs when there is a sudden reduction in blood supply to your brain, usually because of a blood clot or bleed.
• Signs of a stroke can include a drooping face, difficulty moving your arm(s), or slurred speech.
• If you notice signs of a stroke, call triple zero (000) immediately, since any delay may lead to permanent brain damage or death.
• Treatment for a stroke can include medicines to dissolve the clot, surgery, strict control of your blood pressure and a long rehabilitation process.
• You can reduce your chance of having a stroke by managing risk factors such as high blood pressure and cholesterol. Eating healthily and exercising will also help.

Relevant tests

There are no specific laboratory tests for the diagnosis and management of stroke but is it likely that if your doctor suspects you have had a stroke he may request a range of pathology tests to monitor and manage your condition.

Some key tests used to monitor stroke risk are blood pressure measurements, cholesterol and glucose blood tests, ECG to check for atrial fibrillation (AF) and other irregular heart rhythms, carotid ultrasound, and brain imaging in some cases.

These tests will help to detect underlying conditions that increase the chance of a stroke.
