The cerebellum is located in the lower part of the brain, towards the back. This part of the brain plays a role in body movement, eye movement, and balance.
A cerebellar stroke occurs when the brain’s blood supply to this area is interrupted. Without blood, the brain tissue quickly dies. This results in the loss of certain functions.
An ischemic stroke is caused by a blockage of the blood flow, which may be due to:
A hemorrhagic stroke is caused by a burst blood vessel. Blood spills out of the broken blood vessel and pools in the brain. This interrupts the flow of blood and causes a build up of pressure on the brain.
Certain factors increase your risk of stroke but can not be changed, such as:
Other factors that may increase your risk can be changed, such as:
Certain medical condition that can increase your risk of stroke. Management or prevention of these conditions can significantly decrease your risk. Medical conditions include:
Risk factors specific to women include:
Symptoms of a cerebellar stroke come on suddenly and may include:
If you or someone you know has any of these symptoms, call for emergency medical services right away. Brain tissue without blood flow dies quickly. Early care can decrease damage.
A physical exam will be done to look for muscle weakness, visual and speech problems, and movement difficulty. If possible, you will be asked about your symptoms and medical history.
Images may be taken of your bodily structures. This can be done with:
Blood tests can also help identify clotting problems in the blood. The fluid that surrounds your brain and spine may be examined.
Immediate treatment is needed to:
For an ischemic stroke, the doctor may give medications to:
For a hemorrhagic stroke, the doctor may give medications to:
For an ischemic stroke, the doctor may do surgery to:
A catheter may also be passed through the blood vessels to the blocked area. The catheter can help remove the clot or deliver medication directly to the area.
For a hemorrhagic stroke, the doctor may:
A rehabilitation program focuses on:
Many of the risk factors for stroke can be changed. Lifestyle changes that can help reduce your chance of getting a stroke include:
