The cerebellum is the lower part of the brain. It sits towards the back. This part of the brain helps with body movement, eye movement, and balance.
A cerebellar stroke happens when the blood supply to the left side of the brain is interrupted. Blood brings oxygen and nutrients to brain tissue. When blood flow is stopped, the brain tissue quickly dies.

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. It also causes a buildup of pressure on the brain.
Some 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 issues can increase your risk of stroke. Management or prevention of these conditions can significantly decrease your risk of stroke. 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. The doctor will look for muscle weakness, and problems with movement. Vision and speech will also be checked. If possible, you will be asked about your symptoms and past health.
Images may be taken of the brain. This can be done with:
Blood tests will show if there is a problem with blood clotting.
Immediate treatment is needed to:
For an ischemic stroke, the doctor may give medicine to:
For a hemorrhagic stroke, the doctor may give medicine 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:
