Cerebellar Stroke

(Stroke, Cerebellar)

Definition

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.

There are two main types of stroke ischemic and hemorrhagic. An ischemic stroke is the most common type of stroke.

Causes

An ischemic stroke is caused by a blockage 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 interrupts the flow of blood and causes a build up of pressure on the brain.

  • Race—People of African American, Hispanic, or Asian/Pacific Islander descent are at increased risk.
  • Age: Older than 55 years of age
