An ischaemic stroke happens when a blood clot, or other blockage, cuts off the blood supply to your brain. This is the most common type of stroke.
A transient ischaemic attack, TIA, or mini-stroke, is the same as a stroke, but the symptoms last a short time. A TIA is a warning that you are at risk of having a stroke.
A haemorrhagic stroke is due to bleeding in or around the brain. While less common than strokes that are caused by a blockage, they can be much more serious.
