The brainstem is just above the spinal cord. It helps to control automatic roles like heartbeat, breathing, and blood pressure. This makes brainstem’s job vital. The brainstem also controls movement for the eyes and muscle movement. It also controls how you hear, talk, chew, and swallow.
A brainstem stroke happens when the blood supply to the area is stopped. Blood brings oxygen and nutrients to brain tissue. When blood flow is stopped, the brain tissue quickly dies. Since the brainstem has a vital role, this damage can lead to death.
An ischemic stroke is caused by a block of the blood flow, which may be due to:
A clot from another part of the body like the heart or neck. The clot breaks off and flows through the blood until it becomes trapped in a blood vessel supplying the brain.
A clot that forms in an artery that supplies blood to the brain.
A tear in an artery supplying blood to the brain. This is called an arterial dissection.
A hemorrhagic stroke is caused by a burst blood vessel. Blood spills out of the broken blood vessel and pools in the brain. This slows or stops the flow of blood and causes a build up of pressure on the brain.
