Are any tests needed?
Average rating:
A doctor can usually diagnose a stroke by the typical symptoms and signs which develop suddenly. Tests which are commonly done include:
- A brain scan (CT scan or MRI scan). This can determine the type of stroke (ischaemic or haemorrhagic) and rule out rare conditions which may have caused the stroke, or which may mimic a stroke.
- Blood tests to check on such things as blood sugar level and cholesterol level. High levels can increase the risk of a further stroke.
- Chest x-ray and ECG (a heart tracing) to check for heart or lung conditions which may be a cause of stroke (for example, atrial fibrillation).
- Ultrasound scan of the carotid arteries in the neck to check if there are large patches of atheroma in these arteries.
