- Less common than ischemic strokes
- Symptoms usually occur suddenly
- May not have any warning signs, but is often associated with a severe headache, nausea and vomiting
- Higher fatality rate and poorer overall prognosis
- More likely to occur in younger people
A hemorrhagic stroke occurs when a blood vessel in the brain ruptures or breaks. There is bleeding into the surrounding brain tissue. There is a change in the normal flow of blood. Nerve cells in certain areas of the brain may not get enough oxygen and nutrients. The blood from the ruptured artery will usually form a clot. This clot may push on brain tissue and cause problems with brain function.
i. Intracerebral Hemorrhage: This is when the bleeding occurs within the brain tissue itself.
ii. Subarachnoid: The bleeding occurs in the space under the membrane surrounding the brain (subarachnoid space).
TIA (transient ischemic attack)
i. A warning stroke, or mini-stroke that produces stroke-like symptoms but no lasting damage.
ii. The short duration of the symptoms and lack of permanent brain injury is the main difference between TIA and stroke.
