• Alternative names: Cerebrovascular accident/ disease (CVA), Cerebral infarction, Cerebral hemorrhage.

Tests• Computed Tomography (CT)• Magnetic Resonance Imaging (MRI)• Cerebral Angiography: identify responsible
blood vessel• Electrocardiogram (ECG): underlying heart
conditions• Echocardiogram: blood clot from heart• Carotid Duplex: carotid artery stenosis• Heart monitors, blood work and many more
tests!!

Ischemic Stroke:• A blood vessel
becomes blocked and the blood supply to that part of your brain is blocked.
• Types of Ischemic strokes:– Thrombotic Stroke– Embolic Stroke

Treatments• Tissue plasminogen activator (tPA) can be
given within three hours from the onset of symptoms.
In addition to being used to treat strokes, the following can also be used as preventative measures.– Anticoagulants/Antiplatelets– Carotid Endarterectomy– Angioplasty/Stents

Hemorrhagic Stroke:
• A small blood vessel in the brain becomes weak and ruptures.
• Types of hemorrhagic stroke:– Intracerebral hemorrhage
(ICH)– Subarachnoid
hemorrhage

Treatment• Surgery is often required to remove
pooled blood from the brain and to repair damaged blood vessels.
Prevention:• An obstruction is introduced to prevent
rupture and bleeding of aneurysms and arteriovenous malformations (AVM).– Surgical Intervention– Endovascular Procedures

Transient Ischemic Attack (TIA)
• Blood supply to the brain is only briefly interrupted
• Symptoms do not last long
• Warning Stroke- steps should be taken to prevent future stroke.

Prevention• Control high Blood Pressure• Lower cholesterol• Quit smoking• Control diabetes• Maintain healthy weight• Exercise• Manage stress• Eat a healthy diet

Prognosis• The results of a stroke vary depending
on the size and location, the presence of any associated medical problems, and the likelihood of recurring strokes.
• Dysfunctions correspond to the area in the brain that had been damaged.
