Stroke Information

Types of Stroke

Ischemic Strokes account for 87 percent of all strokes and are caused by a blood clot or blockage in an artery.

TIA (transient ischemetic attack) or “mini stroke” is a temporary loss of blood flow to the brain. TIA is an important warning that a stroke is likely to occur. Signs and symptoms of a TIA are the same as stroke and may last minutes to hours.

Hemorrhagic strokes occur when weakened blood vessels within the brain rupture and bleed into the surrounding tissue. This type of stroke affects larger areas of the brain and its symptoms are more sudden and severe, carrying a greater risk of death.
