A cerebrovascular accident (CVA) is the medical term for a stroke, which occurs when the blood flow to a part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen

. There are two main types of strokes: ischemic and hemorrhagic

. Ischemic strokes are caused by a blockage, while hemorrhagic strokes are caused by the rupture of a blood vessel

. Strokes can lead to permanent brain damage if not treated promptly, so it is crucial to seek medical attention immediately if you suspect a stroke

. Some warning signs of a stroke include sudden numbness or weakness of the face, arm, or leg, particularly on one side of the body, and confusion

. Treatment for strokes varies depending on the type and severity. For ischemic strokes, acute treatments may include medications to dissolve the blood clot, such as tPA (tissue plasminogen activator), which can be administered within 4 hours of symptom onset

. For hemorrhagic strokes, treatment may involve surgery to remove the source of bleeding and control swelling

. Preventive measures for strokes include maintaining a healthy lifestyle, avoiding certain risk factors such as smoking and excessive alcohol consumption, and taking medications to reduce the risk of blood clot formation

. If you have experienced a stroke or transient ischemic attack (TIA), your doctor may recommend rehabilitation to overcome disabilities caused by the event and prevent future strokes
