Ischemic Stroke (Clots)

Occurs when a blood vessel supplying blood to the brain is obstructed. It accounts for 87% of all strokes.

Hemorrhagic Stroke (Bleeds)

Occurs when a weakened blood vessel ruptures.

The two types of weakened blood vessels that usually cause hemorrhagic stroke are aneurysms and arteriovenous malformations (AVMs). The most common cause of hemorrhagic stroke is uncontrolled high blood pressure.

Transient Ischemic Attack (TIA)

Is a “warning stroke” caused by a temporary clot. Take this warning sign for stroke seriously — call 911 immediately.

Cryptogenic Stroke

In most cases, clots that block blood flow to the brain cause a stroke. Sometimes, the cause of a stroke can’t be determined. This is called a cryptogenic stroke.

Brain Stem Stroke

When stroke occurs in the brain stem, it can affect both sides of the body and may leave a person in a “locked-in” state. When a locked-in state occurs, the patient is generally unable to speak or move below the neck.
