The aim of the present cross\u2010sectional study is to evaluate executive dysfunction using the Frontal Assessment Battery (FAB) screening test in two groups and to investigate the interaction with other cognitive impairments.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> Among 170 consecutive patients with Alzheimer's disease or A\u2010MCI, we recruited 48 subjects who were under 75\u2003years of age and had been diagnosed as having either A\u2010MCI or EAD. We then compared the total and the subtest scores of the mini\u2010mental state examination (MMSE) and the FAB between the two groups. Moreover, we investigated the statistical interactive associations of the FAB subtest scores with the influential MMSE subtest scores or the diagnosis (A\u2010MCI or EAD).<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> No significant differences in the age, sex ratio, duration of illness, and education years were observed between the two groups. However, significant differences in the FAB total and subtest scores (conflicting instructions and go\/no\u2010go) were found between the two groups. Furthermore, significant differences in the MMSE total and subtest scores (orientation, memory delayed recall, and attention and calculation) were also noted between the two groups. In a generalized linear model analysis, only two FAB subtest scores (conflicting instructions and go\/no\u2010go) were significantly influenced by the diagnosis (A\u2010MCI or EAD) in a manner that was independent of the interaction with the orientation or memory delayed recall.<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> The present findings suggest that the FAB total score and subtest scores reflecting interference performances (conflicting instructions and go\/no\u2010go) significantly declined in patients with EAD, independent of the disorientation and memory disorder. Such characteristics of neuropsychological screening test scores may be useful to clinicians for differentiating EAD and A\u2010MCI at bedside.<\/jats:p>","DOI":"10.1111\/j.1479-8301.2011.00377.x","type":"journal-article","created":{"date-parts":[[2011,10,27]],"date-time":"2011-10-27T08:01:00Z","timestamp":1319702460000},"page":"235-241","source":"Crossref","is-referenced-by-count":20,"title":["Differentiation
