Abstract:
Objective:To evaluate the value of Facial Emotion Recognition Test (FERT) in the early diagnosis of behavioral variant frontotemporal dementia (bvFTD).Methods:A total of 27 patients with mild bvFTD, 27 patients with mild Alzheimer′s disease (AD) and 54 normal controls were successively collected in the Memory Clinic of Department of Neurology,Xuanwu Hospital, Capital Medical University from January 2018 to July 2019. The subjects were assessed by the FERT and a battery of neuropsychological background tests including Mini-Mental State Examination, Frontal Assessment Battery (FAB), and Auditory Verbal Learning Test (AVLT), etc. The discriminatory power of the FERT was evaluated using the receiver operating characteristic curve (ROC).Results:The average FERT scores of bvFTD, AD and control groups were 18.00 (14.00, 21.00), 25.00 (21.00, 28.00) and 28.00 (26.00, 30.00) respectively. The FERT scores of bvFTD group were significantly lower than those of control groups ( H=-55.278, P<0.001) and AD groups ( H=-28.407, P=0.002). ROC results showed that the FERT had a high discriminatory power for differentiating bvFTD from the controls, with an area under the curve (AUC) value of 0.969 (95% CI 0.931-1.000, P<0.001). Both the sensitivity and specificity were 92.6% with a cut-off value at 24. For differentiating bvFTD group from AD group, the AUC value for the FERT was 0.850 (95% CI 0.749-0.951, P<0.001), with sensitivity of 81.5% and specificity of 71.4% with a cut-off value of 22. Compared with the AUC values for the FAB and AVLT-Delayed Recall (0.776 and 0.714), the AUC value for the FERT was slightly higher, though the differences among them were not statistically significant. Conclusions:Disturbance of emotion processing is presented in the early stage of bvFTD. FERT is one of the sensitive and specific neuropsychological indicators for the early diagnosis of bvFTD.
