Subarachnoid Hemorrhage (SAH)

This is bleeding that happens between your brain and the membrane that surrounds it. It leads to stroke and to a dangerous buildup of pressure in your brain.

Causes

What causes this type of hemorrhage? Most often, it results from a brain aneurysm. That's when a blood vessel in your brain bulges and bursts. It also can be caused by a dangerous tangle of blood vessels in your brain. We call that an "arteriovenous malformation" (or "AVM"). And, a hemorrhage can result from a head injury.

Symptoms

What are the symptoms? You may have a sudden, severe headache. You may have nausea and vomiting. And, you may lose consciousness.

Treatment

This type of hemorrhage is a medical emergency. We need to stop the bleeding and lower the pressure in your brain. This can be done with surgery, medications and other methods. And later, you may need therapy to help with complications of stroke. Your healthcare provider will create a plan that's right for you.
