Types of Stroke
is the third leading cause of death and the number one cause of
long-term disability in the United States. Approximately 700,000
Americans will have a stroke this year; that's someone every 45 seconds.
Ischemic Stroke accounts for about 83 percent of all
cases. Ischemic strokes occur as a result of an obstruction
within a blood vessel supplying blood to the brain.
Hemorrhagic stroke accounts for about 17 percent of
stroke cases. It results from a weakened vessel that ruptures
and bleeds into the surrounding brain.
Transient ischemic attacks, also known as TIAs, are minor
or warning strokes. In a TIA, conditions indicative of an
ischemic stroke are present and the typical stroke warning signs
develop. However, the obstruction (blood clot) occurs for a
short time and tends to resolve itself through normal
mechanisms. 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.
