Stroke 1Monday, April 11, 2011
Stroke or brain attack is a sudden problem affecting the blood vessels of the brain. There are several types of stroke, and each type has different causes. Dr. Edward Hill discusses the different types of stroke in todays 60 Second Housecall.
Blood flow to the brain can be impaired in two ways. The vessel can become stopped up, which causes an ischemic stroke. Or the vessel can rupture, causing blood to leak into the brain, known as a hemorrhagic stroke.
Ischemic stroke is the most common type. It results from an obstruction in the artery, typically a blood clot. Hemorrhagic stroke results from a weakened vessel that ruptures and bleeds into the surrounding brain. The blood accumulates and compresses the surrounding brain tissue.
Sometimes a major stroke is preceded by temporary stroke-like symptoms known as transient ischemic attacks or TIAs. This occurs when a blood clot or other particle temporarily clogs an artery and part of the brain doesnt get the supply of blood it needs.
Even though the symptoms disappear after a short time, TIAs are strong indicators of a possible major stroke. Steps should be taken immediately to prevent a stroke.
Report temporary loss of strength, sensation, speech or visual problems to your physician immediately. Dont risk a devastating stroke.
