Ischemic Brain Injury (Stroke):  The brain needs oxygen and nutrients such as glucose (sugar) to provide energy for its normal functions.  Oxygen and nutrients are delivered to the brain through the blood.  If the blood supply is disrupted, the brain is deprived of oxygen and nutrients, which results in neurologic dysfunction.  Decreased oxygen delivery to the brain is referred to as ischemia.  An obstruction in a blood vessel with loss of blood supply to an area of the brain is called an infarction.  In people, an infarction is called a stroke.  Ischemic brain injury is an uncommon event in animals; it occurs more frequently in dogs than in cats.  (More information in below attachment...)
