Ischemic Stroke is Caused by Obstructed Blood Vessels
An ischemic stroke occurs when an artery supplying the brain with blood is obstructed by a blood clot, and it is the most common type of stroke individuals in the United States experience. It is almost always caused by the accumulation of fatty deposits along blood vessel walls ¨C a condition known as atherosclerosis, or hardening of the arteries. One type of ischemic stroke is called cerebral thrombosis, which happens when a clot grows within the arteries that directly supply the brain with blood. Another type is called cerebral embolism, and it occurs when a clot from another area of the body breaks off and circulates through the bloodstream before becoming stuck in the much smaller vessels supplying blood to the brain. Both types of ischemic stroke are dangerous; any time blood flow to the brain is reduced, there is the risk of damage to the brain tissue and loss of function. Tampa General Hospital provides treatment and rehabilitation for people who have experienced all types of strokes ¨C ischemic and otherwise ¨C as the only comprehensive stroke center in Hillsborough County.
An ischemic stroke shares most of its symptoms with hemorrhagic strokes and transient ischemic attacks (also known as ¡°mini-strokes¡±), so it takes medical testing to determine which type of stroke someone may have experienced. Common stroke symptoms include:
- Numbness or weakness on one side of the body
- Trouble walking properly
- Paralysis of the face, arm, or leg
- Vision problems in one or both eyes
- Problems comprehending speech or speaking
