Frontal Assessment Battery (FAB)
Frontal Assessment Battery (FAB; Dubois 2000): six executive-function subtests, each 0-3, summed to 0-18 (higher = better).

Example
- Conceptualization
- 2
- Mental flexibility / verbal fluency
- 2
- Motor programming / Luria series
- 2
- Sensitivity to interference
- 2
- Inhibitory control / go-no-go
- 1
- Environmental autonomy / prehension
- 1
Result: FAB 10 of 18 — suggests frontal / executive dysfunction (cut-point < 12).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Subtests
- conceptualization, mental flexibility, motor programming, sensitivity to interference, inhibitory control, environmental autonomy - each 0-3 = 0-18.
- < 12
- Suggests frontal / dysexecutive dysfunction (helps separate a frontal pattern from Alzheimer-type). Cut-point depends on age and education. Higher = better.
What you enter

- Motor programming / Luria series (0-3)
- Sensitivity to interference (0-3)
- Inhibitory control / go-no-go (0-3)
- Environmental autonomy / prehension (0-3)
