Stroke 4Thursday, April 29, 2010
There are several types of stroke, and each type has different causes. The treatment you receive may be different depending on the type of stroke you have. Dr. Edward Hill discusses the types of stroke in todays 60 Second Housecall.
Strokes are typically classified two ways. Those caused by a blockage of blood flow to the brain are known as ischemic stroke. Hemorrhagic stroke is caused by bleeding in the brain.
Ischemic is the most common type, responsible for about 80 percent of strokes. Blockages can occur by the formation of a clot within a blood vessel of the brain or neck; the movement of a clot from another part of the body such as the heart; or the severe narrowing of a brain artery.
Hemorrhagic stroke can occur when a blood vessel bursts, usually from severe high blood pressure or from an aneurysm.
Sometimes a major stroke is preceded by temporary stroke-like symptoms, called TIAs, or transient ischemic attacks. TIAs are strong indicators of a possible major stroke. If you have a temporary loss of strength, sensation, speech or visual problems, report this to your physician immediately. Early and aggressive medical intervention may prevent disability or even save your life.
