The blood from that artery creates excess pressure in the skull and swells the brain, damaging brain cells and tissues. Hemorrhagic strokeĪ hemorrhagic stroke happens when an artery in the brain breaks open or leaks blood. Up to 10 to 15 percent of people who experience a TIA have a major stroke within 3 months.

While it’s not technically categorized as a full stroke, a TIA serves as a warning that an actual stroke may happen. However, they’re typically temporary and disappear after a few minutes or hours, when the blockage moves and blood flow is restored.Ī blood clot usually causes a TIA. Symptoms are similar to those of a full stroke. Transient ischemic attack (TIA)Ī transient ischemic attack, often called a TIA or ministroke, occurs when blood flow to the brain is blocked temporarily. The clot gets stuck, and stops the flow of blood and causes a stroke.Ĭerebral thrombosis (often referred to as thrombotic stoke) occurs when a blood clot develops at the fatty plaque within the blood vessel.Īccording to the CDC, 87 percent of strokes are ischemic strokes. There are two types of blockages that can lead to ischemic stroke: a cerebral embolism and cerebral thrombosis.Ī cerebral embolism (often referred to as embolic stroke) occurs when a blood clot forms in another part of the body - often the heart or arteries in the upper chest and neck - and moves through the bloodstream until it hits an artery too narrow to let it pass. Pieces of plaque breaking off and blocking a blood vessel can also cause them. Blood clots or severely reduced blow flow to the brain causes these blockages. Ischemic strokeĭuring an ischemic stroke, the arteries supplying blood to the brain narrow or become blocked. The type of stroke you have affects your treatment and recovery process.
