The diagnostic accuracy of the German version of the revised Addenbrooke´s Cognitive Examination (ACE-R) in identifying mild cognitive impairment (MCI), mild dementia in Alzheimer´s disease (AD) and mild dementia in frontotemporal lobar degeneration (FTLD) in comparison with the conventional MMSE was assessed. The study encompasses 76 cognitively healthy elderly individuals, 75 patients with MCI, 56 with AD and 22 with FTLD. Statistical analysis was performed using the ROC method and regression analyses. The optimal cut-off score for the ACE-R for detecting MCI, AD and FTLD was 86/87, 82/83 and 83/84, respectively. ACE-R was superior to MMSE only in the detection of patients with FTLD (AUC 0.97 vs. 0.92). The ratio of the score of the memory ACE-R subtest to verbal fluency subtest contributed significantly to the discrimination between AD and FTLD (optimal cut-off score 2.30/2.31, AUC 0.77).
