At the time symptoms occur, a TIA and a stroke are difficult to tell apart. In both cases, it is critical that the victim receives rapid medical attention. The symptoms may appear harmless at first, but they may not resolve. In fact, they can worsen.

For a stroke, quick medical care can minimize brain damage and reduce the risk of lasting impairments. TIAs may not be minor — symptoms can be quite severe even though they leave no permanent damage to the brain. A person who experiences a TIA may have a percent risk of having a full stroke in the next seven days depending on the cause, Streib said.

The American Stroke Association confirms that 9 to 17 percent of people who have had a TIA have a stroke within 90 days. If they seek the proper care, patients can reduce that risk significantly. To significantly reduce the risk of stroke, a person who has experienced a TIA must seek the proper follow-up care immediately after the episode.

There are two kinds of stroke due to ruptured blood vessels:. In both types of hemorrhagic stroke, blood flow is disrupted to part of the brain.

Victims of hemorrhagic strokes are often younger and the fatality rate is higher than for ischemic stroke. Overall prognosis is also poorer for those who have hemorrhagic strokes. About 10 percent of strokes follow incidents called transient ischemic attacks, or TIAs. Aneurysms may be congenital present at birth , or may develop later in life due to such factors as high blood pressure or atherosclerosis. An AVM is a congenital disorder that consists of a disorderly tangled web of arteries and veins.

The cause of AVM is unknown, but it is sometimes genetic or part of certain syndromes. Recurrent strokes occur in about 1 in 4 people who have had a stroke within 5 years after a first stroke. The risk is greatest right after a stroke and decreases over time. The likelihood of severe disability and death increases with each recurrent stroke.

Strokes can be classified into 2 main categories: Ischemic strokes. What is an ischemic stroke? Ischemic strokes are further divided into 2 groups: Thrombotic strokes. Thrombotic stroke Thrombotic strokes are strokes caused by a thrombus blood clot that develops in the arteries supplying blood to the brain.

Embolic stroke Embolic strokes are usually caused by a blood clot that forms elsewhere in the body embolus and travels through the bloodstream to the brain.
