FAB-D: German version of the Frontal Assessment Battery

Executive dysfunction (ED) is a frequent consequence of neurological disorders, such as stroke, trauma or dementia, but also appears in normal aging. We developed a German version of the Frontal Assessment Battery (FAB-D), a short test which has previously been developed (Dubois et al., Neurology 55:1621-1626, 2000) to detect ED during bedside screening. A sample of 401 cognitively intact subjects aged 50-95 was tested with the FAB-D and several neuropsychological tests tapping executive functions, memory and calculation abilities. Aim of the study was to receive normative data for different age and educational groups, and to learn which tests predict performance on the FAB-D. We found clear effects of age and education; furthermore, FAB-D performance was predicted by other tests of executive functioning, but also by calculation and memory abilities. The present study reports data of healthy individuals and may be useful for comparing patients' performance with a normative sample.
