Hemorrhagic StrokeNot what you're looking for? Show OverviewA hemorrhagic stroke occurs when blood from an artery suddenly begins bleeding into the brain. As a result, the part of the body controlled by the damaged area of the brain cannot work properly. There are two main types of hemorrhagic stroke:
When the stroke is caused by a blockage in an artery that reduces blood flow to the brain, this is known as an ischemic stroke. SymptomsA person experiencing symptoms of a stroke needs immediate emergency care. The sooner medical treatment begins, the fewer brain cells are damaged. The signs of a stroke are:
Symptoms of intracranial hemorrhages and subarachnoid hemorrhages include:
Additional symptoms may include:
Causes and Risk Factors Hemorrhagic stroke is caused by sudden bleeding from a blood vessel inside the brain or in the spaces around the brain. Sudden bleeding may result from:
Uncommon causes of hemorrhagic stroke include inflamed blood vessels or radiation treatments. DiagnosisDiagnosis of a hemorrhagic stroke is based on a thorough medical history and physical exam, and doctors may strongly suspect bleeding inside the skull based on the patient’s symptoms. In cases where a stroke is suspected, imaging tests can help determine whether the stroke was caused by a clot (ischemic stroke) or by bleeding inside the brain (hemorrhagic). Imaging tests include magnetic resonance imaging (MRI) or computed tomography (CT) scans. An electroencephalogram (EEG) or lumbar puncture (spinal tap) may be done to confirm the diagnosis of a hemorrhagic stroke. Tests may be done to check for other conditions, check the patient’s overall health, and see if the patient's blood clots too easily. TreatmentPatients who have symptoms of a hemorrhagic stroke need to seek immediate emergency medical care. Prompt medical attention may prevent life-threatening complications and more widespread damage to the brain. Treatment for a hemorrhagic stroke depends on what caused it, where it's located and the size of the hemorrhage. Treatment options include interventional radiology or neurosurgical procedures, such as surgical clipping or coil embolization, which may also be performed to stop the bleeding and reduce the pressure in the brain. Medicines to reduce swelling, prevent seizures and reduce pain also may be given. The goals of treatment are to prevent life-threatening complications that may occur soon after stroke symptoms develop, prevent future strokes, reduce disability, prevent long-term complications and help the patient get back as much normal functioning as possible through rehabilitation. © 2000-2022 The StayWell Company, LLC.

What are characteristics of a stroke caused by an intracerebral hemorrhage?Intracerebral hemorrhage is focal bleeding from a blood vessel in the brain parenchyma. The cause is usually hypertension. Typical symptoms include focal neurologic deficits, often with abrupt onset of headache, nausea, and impairment of consciousness.
What is the most common cause of a hemorrhagic stroke?What causes hemorrhagic stroke? Hemorrhagic stroke most often occurs when a blood vessel in the brain leaks or ruptures, which is known as a hemorrhagic conversion of an ischemic stroke or a bleeding brain tumor. Other causes include severe brain infection, head trauma, certain bleeding disorders, or an aneurysm.
