Tip This Week- Recognizing Stroke and Early Treatment Considerations
Stroke is occurs when part of the blood supply to the brain in interrupted as in ischemic stroke or blood vessels burst and blood pools into the spaces of the brain or hemorrhagic stroke. Signs and symptoms of stroke include sudden numbness or weakness, especially on one side of the body; sudden confusion or trouble speaking or understanding speech; sudden trouble seeing in one or both eyes; sudden trouble with walking, dizziness, or loss of balance or coordination; or sudden severe headache with no known cause.
Early management and diagnosis of a stroke is essential to a good prognosis. One must consider the presence of risk factors that could predispose an individual to a stroke event such as chronic hypertension, atrial fibrillation and diabetes. Acute stroke therapies try to stop a stroke while it is happening by quickly dissolving the blood clot causing an ischemic stroke or by stopping the bleeding of a hemorrhagic stroke. Medication or drug therapy used to prevent or treat stroke are antithrombotics (antiplatelet agents and anticoagulants) and thrombolytics.
