NIH Stroke Scale (NIHSS) ==== * Purpose: Quantifies neurological deficit in acute stroke. * Range: 0–42 * Interpretation: * 0 = No stroke symptoms * 1–4 = Minor stroke * 5–15 = Moderate stroke * 16–20 = Moderate to severe stroke * 21–42 = Severe stroke * Use: Inclusion/exclusion in thrombolysis and thrombectomy trials. ==== 2. Modified Rankin Scale (mRS) ==== * Purpose: Measures degree of disability or dependence after stroke. * Range: 0–6 * Interpretation: * 0 = No symptoms * 1 = No significant disability despite symptoms * 2 = Slight disability * 3 = Moderate disability * 4 = Moderately severe disability * 5 = Severe disability * 6 = Death * Use: Common endpoint in stroke trials. ==== 3. Glasgow Coma Scale (GCS) ==== * Purpose: Assesses level of consciousness. * Range: 3–15 * Components: Eye (4), Verbal (5), Motor (6) * Use: Useful in hemorrhagic stroke or coma. ==== 4. ASPECTS (Alberta Stroke Program Early CT Score) ==== * Purpose: Quantifies early ischemic changes on non-contrast head CT. * Range: 0–10 * Lower score = More extensive ischemia * Use: Selection for thrombectomy (particularly in anterior circulation). ==== 5. TICI (Thrombolysis in Cerebral Infarction) ==== * Purpose: Grades reperfusion after thrombectomy. * Range: * 0 = No perfusion * 1 = Minimal * 2a = Partial (<50%) * 2b = Substantial (>50%) * 2c = Near complete * 3 = Complete * Use: Angiographic outcome measurement. ==== 6. Barthel Index ==== * Purpose: Measures functional independence in activities of daily living (ADLs). * Range: 0–100 * Use: Rehab planning and long-term prognosis. ==== 7. ABCD2 Score ==== * Purpose: Predicts risk of stroke after TIA. * Factors: Age, BP, Clinical features, Duration, Diabetes * Range: 0–7 * Risk stratification: * 0–3 = Low * 4–5 = Moderate * 6–7 = High ==== 8. SPAN-100 Index ==== * Purpose: Estimates risk/benefit from thrombolysis in elderly. * Calculation: Age + NIHSS * SPAN-100 positive = total ≥100 → high risk of sICH (symptomatic ICH) ==== 9. ICH Score ==== * Purpose: Predicts 30-day mortality in intracerebral hemorrhage. * Factors: GCS, ICH volume, age, location, IVH * Range: 0–6 ==== 10. TOAST Classification ==== * Purpose: Etiological classification of ischemic stroke. * Categories: * Large-artery atherosclerosis * Cardioembolism * Small vessel occlusion (lacune) * Other determined etiology * Undetermined etiology stroke_scales.txt Last modified: 2025/07/10 21:11by administrador
