The two main types of stroke are hemorrhagic and ischemic, which is the more common type.
An ischemic stroke happens if an artery that supplies the brain with oxygen-rich blood is blocked. Ischemic strokes are quite often the result of blockages caused by blood clots.
A hemorrhagic stroke is what happens iif an artery in the brain breaks open (ruptures) or leaks blood. Brain cells are damaged by the pressure of the leaked blood. Aneurisms and high blood pressure are two of the conditions that may result in hemorrhagic strokes.
Diagnosing a stroke
Your doctor will diagnose a stroke based on your your medical history, the signs and symptoms you exhibit, a physical exam, and the results of various tests. Your doctor should determine the type of stroke you’ve experienced, the cause of the stroke, which area of the brain is affected, and if there is bleeding in your brain.

If your doctor determines that you’ve had a TIA (transient ischemic attack), she or he will search for what caused it, so they can — hopefully — help you to avoid a stroke in the future.
Treatment for a stroke is based on whether it is hemorrhagic or ischemic. When the condition is a TIA (transient ischemic attack), the treatment will depend on how much time has passed since symptoms began, what likely caused the TIA, and whether there are additional medical conditions involved.
