Stroke occurs when blood flow to a part of the brain is interrupted, either due to a blockage (ischemic stroke) or bleeding (hemorrhagic stroke). This leads to sudden neurological deficits, as brain cells are deprived of oxygen and nutrients. Common causes include atherosclerosis, hypertension, heart disease, aneurysms, or vascular malformations. Symptoms may include sudden weakness, numbness, facial drooping, speech difficulties, vision changes, dizziness, or severe headache. Prompt recognition and intervention are crucial, as early treatment can significantly reduce brain damage, improve recovery outcomes, and prevent life-threatening complications. Understanding stroke types and risk factors helps guide timely evaluation and management.
Diagnosis involves a detailed neurological examination combined with imaging studies such as CT scans, MRI, or CT/MR angiography to identify the type, location, and extent of brain injury. Blood tests and cardiac evaluations may be performed to determine underlying causes. Early and precise assessment is critical to plan appropriate interventions, whether thrombolysis, thrombectomy, or surgical management, ensuring the best possible neurological outcome.
Treatment depends on stroke type and severity. Ischemic strokes may be treated with thrombolytic therapy, mechanical thrombectomy, or antiplatelet medications to restore blood flow. Hemorrhagic strokes often require surgical intervention such as craniotomy, hematoma evacuation, aneurysm clipping, or endovascular procedures to stop bleeding and relieve pressure. Supportive care includes controlling blood pressure, managing complications, and preventing secondary strokes.
Recovery focuses on restoring neurological function and independence. Rehabilitation may include physiotherapy, occupational therapy, speech therapy, and cognitive exercises. Lifestyle modifications, medications, and risk factor management are essential to prevent recurrence. Early and structured rehabilitation improves functional outcomes, reduces disability, and enhances quality of life for stroke survivors.
