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

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
a. < 50 2
b. 50–70 1
c. > 70 0
2) Presence of hypertension/hyperlipidemia/diabetes mellitus/atrial fibrillation (AF):  
a. None 3
b. 1 without AF 2
c. 2 or 3 without AF 1
d. AF 0
3) History of migraine 2
4) History of epilepsy 1
5) History of psychiatric illness 1
  Minimum: 0
Maximum: 9
  1. AF indicates atrial fibrillation; NIHSS National Institute of Health Stroke Scale
