What Is a Stroke?

Ischemic Strokes (Too Little Blood Flow)

Ischemic stroke’s occur as a result of a blockage or clot within a blood vessel supplying blood to the brain. These are the most common types of stroke. Time is brain; these strokes require immediate and timely recognition. Call 911 can get your family member to the hospital immediately for medical treatment and potential “clot-busting” medication.

Hemorrhagic (Too Much Blood Flow)

Hemorrhagic Strokes are caused by a weak blood vessel that bursts and produces bleeding into the brain. The blood ends up damaging the part of the brain it surrounds. These are not as common as an ischemic stroke. Hemorrhagic Strokes demand emergent medical treatment and care.


A transient ischemic attack (TIA) is as serious a medical emergency as an ischemic stroke. A TIA is a “mini” stroke, where the blockage by a clot is temporary and your symptoms resolve. Your risk of having a full stroke is very high, and you should seek medical attention immediately.

How Is Stroke Diagnosed?

Before treatment we need to determine what type of stroke you are having, ischemic or hemorrhagic. A comprehensive neurologic exam, head CT, lab work, and further testing helps the care team determine a diagnosis of stroke.
