Cryptogenic Stroke

WHAT IS A STROKE?

Strokes are caused by a sudden interruption in blood flow to a part of the brain or bleeding within the brain tissue. When this happens, brain cells are deprived of oxygen and begin to die, causing brain damage. When brain cells die during a stroke, the function controlled by that part of the brain, like speech or movement, may be impaired.

There are two major types of stroke: hemorrhagic stroke and ischemic stroke. A hemorrhagic stroke occurs when damaged blood vessels in the brain allow bleeding into the brain tissue resulting in swelling and pressure that damages the brain. An ischemic stroke occurs when a blockage develops in a blood vessel carrying blood to the brain.

WHAT IS A CRYPTOGENIC STROKE?

An ischemic stroke—for which no definite cause is found—is known as a cryptogenic stroke. It is estimated that 25% to 30% of ischemic strokes are cryptogenic.1

One possible factor that may have contributed to your cryptogenic stroke is the presence of a Patent Foramen Ovale (PFO).
