What is a Stroke/Brain Attack? - National Stroke Association

Thrombolytic agents: Acute interventional drugs which work directly to

break up or dissolve stroke-causing clots.

Thrombolytics were first used successfully to treat

heart attacks. Many other thrombolytic drugs are in

clinical trials. T-PA (tissue plasminigen activator) is the

only FDA-approved acute stroke treatment.

Thromboembolism: An embolus that originates in and breaks away from a

clot on one vessel to become lodged in another


Thrombosis: The clotting of blood within a vessel.

Thrombotic stroke: A stroke resulting from the blockage of a blood vessel

by accumulated deposits, with blockage made

complete when a clot develops or lodges on top of the

deposits, preventing the free flow of blood.

Transient ischemic attack: Called TIAs, transient ischemic attacks are temporary

interruptions of the blood supply to an area of the

brain, typically caused by carotid stenosis. During a

TIA, a person experiences a sudden onset of stroke

symptoms. By definition, a TIA can last up to 24

hours, but most last only a few minutes and cause no

permanent damage or disability. Sometimes called

“mini-strokes,” TIAs must be taken seriously because

they are usually a precursor to full strokes.

Unilateral neglect: A disturbance of a person's awareness of space on the

side of the body opposite a stroke-causing lesion;

often referred to as hemi-inattention.

Vertebrobasilar arteries: The two arteries in the back of the neck which supply

blood to the brain stem and cerebellum.
