ABSTRACT
Objective@#People with schizophrenia show impairment in social cognition, such as emotion recognition and theory of mind. The current study aims to compare the ability of clinically stable schizophrenia patients to decode the positive, negative and neutral affective mental state of others with educational match-paired normal control. @*Methods@#50 people with schizophrenia and 50 matched controls were compared on the positive, negative and neutral emotional valence of affective theory of mind using the Reading the Mind in the Eyes Tests. @*Results@#The results showed that people with schizophrenia performed worse in negative and neutral emotional valence than normal controls; however, no significant differences in decoding positive valence were found. @*Conclusion@#Our data suggest that there is variability in the performance of affective theory of mind according to emotion valence; the impairments seem to be specific to only negative and neutral emotions, but not positive ones.
ABSTRACT
The objective of our study was to assess the accuracy of the Thai version of the Addenbrooke's Cognitive Examination III (ACE-T). We used the ACE-T to assess 107 participants aged 60 or over, divided into the following groups: early dementia, n=30; mild cognitive impairment (MCI), n=29; and normal controls (NC), n=48. The ACE-T exhibited good internal consistency (0.93) and inter-rater reliability (1.0). The optimal cut-off score for the ACE-T to differentiate MCI from NC was 75/76, giving a sensitivity of 0.9 and specificity of 0.86. At the optimal cut-off of 61/62, the ACE-T had excellent sensitivity (1.0) and specificity (0.97) to distinguish early dementia from non-dementia. The ACE-T had high diagnosis accuracy in the detection of the MCI and early dementia in the Thai population.
