Table 1 Components of Individual Stroke Mimic Prediction Scales
From: External validation of stroke mimic prediction scales in the emergency department
Score | Clinical Variables | Scores | Indicator |
|---|---|---|---|
FABS | 1) Absence of Facial Droop 2) Age < 50 years 3) Absence of Atrial Fibrillation 4) Systolic blood pressure < 150 mmHg at presentation 5) Presence of Isolated sensory deficit 6) History of seizure disorder | 1 point per variable. Minimum 0, Maximum 6 | Higher the score, more likely a stroke mimic |
Simplified FABS | 1) Absence of Facial Droop 2) Age less than 50 years 3) Absence of Atrial Fibrillation 4) Systolic blood pressure less than 150 mmHg at presentation | 1 point per variable. Minimum 0, Maximum 4 | Higher the score, more likely a stroke mimic |
TeleStroke Mimic | 1) Age (per year) 2) Atrial Fibrillation 3) Hypertension 4) Seizures 5) Facial weakness 6) NIHSS > 14 | + 0.2 per year + 6 + 3 − 6 + 9 + 5 Minimum: − 6, maximum: no upper limit | Higher the score, less likely the stroke mimic |
Khan score | 1) Age | Higher the score, more likely a stroke mimic | |
