Stroke and Aneurysms

Your brain controls everything in your body, from the beating of your heart to your ability to see, hear, think, and understand the world. Your brain needs a steady supply of blood and oxygen to function. If it doesn’t get it, brain damage can occur.


Stroke occurs when part of your brain is damaged due to lack of blood flow. Stroke can be caused by a clot or by a broken blood vessel.

Types of Stroke

There are three main types of strokes:

  • Ischemic stroke – The most common kind of stroke, caused by a blood clot blocking a blood flow to the brain.
  • Hemorrhagic stroke – Caused by a broken blood vessel, usually an aneurysm, that bleeds in or around the brain.
  • Transient ischemic attack (TIA) – Temporary stroke-like symptoms that happen suddenly when a clot briefly blocks blood flow to the brain; sometimes referred to a “mini stroke.”

Know the signs and symptoms of a stroke. If you or a loved one is experiencing any of the stroke symptoms below, call 9-1-1 and seek immediate medical attention. Every second counts.

F - Face (Ask a person to smile. Does one side of the face sag or droop?)
A - Arms (Ask a person to raise both arms. Does one arm drift downward?)
S - Speech (Ask the person to repeat a single sentence. Does the speech sound slurred or strange?)
T - Time (Seconds matter. Call 911 or get to the nearest primary stroke center or hospital.)

A brain aneurysm is a weak, bulging spot in a blood vessel in the brain. Sometimes the artery walls around an aneurysm can become so thin and weak that they burst, allowing blood to flow into the open spaces around the brain. When an aneurysm bursts and brain damage starts to occur, this is called a hemorrhagic stroke.

Aurora BayCare has the area’s largest neurointervention team. We’re leading the way with minimally invasive treatments for stroke, aneurysms, and neurovascular disease. A highly effective alternative to open surgery, these procedures are saving lives and helping more people live disability-free.

Plus, our ongoing commitment to research means our patients benefit from the latest treatment options. In general, cutting-edge treatments are less invasive, so patients receive effective treatment with less risk.

Our patients also benefit from a neuro intensive care unit and specialized neurosurgery nursing teams. These advantages playing a key role in providing better outcomes and a faster, more comfortable recovery.

First and Foremost

  • First and only Certified Comprehensive Stroke Center in the region
  • The most experienced team in the region for stroke, aneurysms, and neurovascular disease
  • The only hospital in the region with 24/7 neurointerventional care
  • The only hospital in the region with 24/7 intensivist coverage in the neuro ICU
