A stroke occurs when a part of the brain loses its blood supply and stops working. This causes the part of the body that the injured brain controls to stop working. A stroke also is called a cerebrovascular accident, CVA, or “brain attack.”
The types of strokes include:
- Ischemic stroke (part of the brain loses blood flow)
- Hemorrhagic stroke (bleeding occurs within the brain)
Transient ischemic attack, TIA, or mini stroke -The stroke symptoms resolve within minutes, but may take up to 24 hours on their own without treatment. This is a warning sign that a stroke may occur in the near future.
From onset of symptoms, there is only a 3 to 4 1/2 hour window to use clot-busting drugs (thrombolytics) to try to restore blood supply to the affected part of the brain. Stroke is diagnosed by the patient’s symptoms, history, and blood and imaging tests. The prognosis and recovery for a person that has suffered a stroke depends upon the location of the injury to the brain.
Remember FAST if you think someone might be having a stroke:
- Face drooping
- Arm weakness
- Speech difficulty
- Time to call emergency
A stroke is a medical emergency because strokes can lead to death or permanent disability. There are opportunities to treat ischemic strokes but that treatment needs to be started in the first few hours after the signs of a stroke begin. The patient, family, or bystanders, should call emergency medical services immediately if they suspect a stroke.
Risk factors of stroke:

Heart conditions like atrial fibrillation, patent foramen ovale, and heart valve disease can also be the potential cause of stroke.
