Stroke

Acute ischemic stroke is a medical emergency that occurs when blood flow to a part of the brain is blocked, leading to the deprivation of oxygen and nutrients. This blockage is often caused by a blood clot or atherosclerotic plaque within the blood vessels supplying the brain. Some acute ischemic strokes are caused by narrowing of the main blood vessels in the neck, known as carotid stenosis. Acute ischemic stroke is the most common type of stroke, accounting for the majority of stroke cases. It manifests as a sudden onset of neurological symptoms, including facial drooping, arm weakness, speech difficulties, and loss of coordination.

The diagnosis of acute ischemic stroke typically involves imaging studies such as a computed tomography (CT) scan or magnetic resonance imaging (MRI) to visualize the brain and identify the affected area. Rapid diagnosis is crucial, as timely intervention can significantly improve outcomes. Intravenous administration of a clot-dissolving medication (tPA or TNK) is a common early treatment for acute ischemic stroke, aiming to restore blood flow by dissolving the clot. Cerebral angiography and mechanical thrombectomy, a procedure where a catheter is used to remove or break up the clot, is another advanced treatment option for eligible patients. Oftentimes, patients require emergency transfer from one to hospital to another in order to receive these potentially lifesaving interventions.

Post-stroke care focuses on rehabilitation and preventing complications. Rehabilitation may include physical therapy, occupational therapy, and speech therapy to help individuals regain lost functions and improve their quality of life. Stroke survivors may also receive medications to manage risk factors, such as anticoagulants for blood clot prevention or medications to control hypertension.

Preventive measures play a crucial role in reducing the risk of acute ischemic stroke. Lifestyle modifications, including a healthy diet, regular exercise, and smoking cessation, contribute to overall cardiovascular health. Managing risk factors such as hypertension, diabetes, and high cholesterol is essential for stroke prevention. Public awareness campaigns and education about the signs of stroke emphasize the importance of seeking immediate medical attention if symptoms occur, as early intervention significantly impacts the likelihood of recovery.

There is ongoing exploration of new technologies, medications, and interventions to enhance the treatment and prevention of acute ischemic stroke. Telemedicine and advancements in prehospital stroke care have improved access to rapid medical attention, particularly in regions where specialized stroke centers may not be readily available. Acute ischemic stroke remains a critical public health concern, highlighting the importance of ongoing research, education, and community outreach to improve outcomes for individuals at risk of stroke.
