Standard Treatment Approaches for Severe Stroke

1. Acute Management

• Emergency Response: Immediate assessment and stabilization of the patient are critical. This includes ensuring airway patency, breathing, and circulation (the ABCs of emergency care).
• Imaging: Rapid neuroimaging, typically a CT scan or MRI, is essential to determine the type of stroke (ischemic or hemorrhagic) and to rule out other conditions.
• Thrombolysis: For ischemic strokes, intravenous thrombolysis with tissue plasminogen activator (tPA) may be administered within a specific time window (usually within 4.5 hours of symptom onset) to dissolve the clot and restore blood flow to the brain[1].
• Mechanical Thrombectomy: In cases of large vessel occlusion, mechanical thrombectomy may be performed, which involves physically removing the clot from the blood vessel using specialized devices. This is typically done within 6 to 24 hours of symptom onset, depending on the patient's condition and imaging results[2].

2. Post-Acute Care

• Neurocritical Care: Patients with a high NIHSS score often require admission to a neurocritical care unit for close monitoring and management of complications such as increased intracranial pressure, seizures, and respiratory issues[3].
• Rehabilitation: Early rehabilitation is crucial for improving outcomes. This may include physical therapy, occupational therapy, and speech therapy, tailored to the patient's specific deficits and needs[4].
• Secondary Prevention: After stabilization, strategies to prevent future strokes are implemented. This may involve antiplatelet therapy (e.g., aspirin or clopidogrel), anticoagulation for specific conditions (e.g., atrial fibrillation), and management of risk factors such as hypertension, diabetes, and hyperlipidemia[5].

3. Long-Term Management

• Follow-Up Care: Regular follow-up with a neurologist and primary care physician is essential to monitor recovery and adjust treatment plans as necessary.
• Support Services: Patients and families may benefit from support groups and educational resources to navigate the challenges of recovery and rehabilitation[6].
