Hemorrhagic Stroke


What is a hemorrhagic stroke?

Hemorrhagic stroke accounts for 13 percent of stroke cases overall. A hemorrhagic stroke occurs due to a ruptured blood vessel. This may occur within the brain tissue itself (intraparenchymal) or into the fluid space around the brain (subarachnoid). The latter type of stroke is typically caused by a ruptured aneurysm.

What are the symptoms of a hemorrhagic stroke?

Symptoms of a hemorrhagic stroke can vary from person to person, but they’re almost always present immediately after the stroke occurs.

Symptoms may include:

  • Loss of consciousness
  • Nausea
  • Vomiting
  • Sudden and severe headache
  • Weakness or numbness in the face, leg, or arm on one side of the body
  • Seizures
  • Dizziness
  • Loss of balance
  • Speech or swallowing difficulty
  • Confusion or disorientation

How is a hemorrhagic stroke diagnosed?

Hemorrhagic stroke is typically first diagnosed with a head CT. Vascular imaging is then performed to assess for a structural arterial lesion as the source of bleeding.

How is hemorrhagic stroke treated?

Patients with hemorrhagic stroke are treated emergently in a variety of ways depending on the cause and severity of the bleeding. A variety of surgical and medical strategies are used to limit further damage to the brain and optimize the chances of recovery.
