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.

Aim To examine the diagnostic accuracy of the Thai version of the Mini‐Addenbrooke's Cognitive Examination (MACE‐T) for detecting mild cognitive impairment and dementia. Methods Participants consisted of 60 controls, 40 people with mild cognitive impairment (MCI) and 48 people with dementia. All participants completed the Thai version of the Addenbrooke's Cognitive Examination – III (ACE‐T) and the MACE‐T scores were obtained from items within the ACE‐T. Results A cut‐off score of 21/22 detected MCI with a sensitivity of 95% (95% confidence interval (CI): 86.1–100) and specificity of 85% (95% CI: 77.8–93.4). A cut‐off score of 16/17 detected dementia with a sensitivity and specificity of 95.8% (95% CI: 88.2–100) and 85% (95% CI: 76.4–89.7), respectively. Using Bayes theorem, the MACE‐T demonstrated high negative predictive values (> 94%) for diagnosing MCI and dementia, independent of their prevalence rates. Education was the only significant predictor of performance in the MACE‐T. Conclusion The MACE‐T is a good short cognitive screening test with high diagnostic accuracy for screening for MCI and dementia.

Impairments in social cognitions in schizophrenia are increasingly reported in the last decade but only a few studies have come from Asia. The objective of the study was to evaluated emotion perception, theory of mind and social knowledge in people with schizophrenia compared to healthy controls. Participants were 36 clinically stable outpatients with schizophrenia and 36 normal controls with comparable age and level of education. We administered general neurocognition test (the Addenbrooke's Cognitive Examination), emotion perception (the Faces Test), theory of mind (the Eyes Test) and social knowledge (the Situational Features Recognition Test; SFRT). Schizophrenia patients displayed obvious impairment in all three social cognition domains i.e. the Faces Test [13.7 (2.9) vs 15.7 (1.9), P=0.001], the Eyes Test [18.9 (4.4) vs 23.5 (4.4), P<0.001] and SFRT [0.85 (0.09) vs 0.9 (0.05), P=0.002]. The performances on three social cognition tests did not correlate with positive symptoms. Only the Faces Test seemed to be related to negative symptoms. The results demonstrated that there are deficits of social cognitions in schizophrenia even in a clinically stable population.

Objective: This study investigates the psychological impacts and their associated factors on patients with COVID-19 at a Thai field hospital. Methods: All eligible patients confirmed to have COVID-19 at Thammasat University field hospital completed an online self-reported mental health screening questionnaire which collected sociodemographic data, their clinical characteristics, and used the depression, anxiety, and stress scale (DASS-21). Results: A total of 40 patients participated in the study. The depression rate was found to be 22.5%, while the anxiety rate was 30%, and the stress rate was 20%. Having a history of psychiatric disorder alone was significantly associated with a higher DASS-21 score (p = 0.001). Meanwhile, gender, age, level of education, occupation, living status, severity of COVID-19, and the number of days admitted to hospital prior to the field hospital were not found to be associated with the DASS-21 scores (P > 0.05). Conclusion:The depression, anxiety, and stress symptoms in patients with COVID-19 at the field hospital were common. Patients with a history of psychiatric disorder should undergo specific evaluation during the isolation phase.

Purpose. To investigate the diagnostic accuracy of the overlapping infinity loops, wire cube, and clock drawing tests (CDT) in the detection of mild cognitive impairment (MCI) and dementia. Method. The participants were 60 normal controls (NC), 35 patients with MCI, and 47 patients with mild dementia. Results. The results illustrate that infinity loops, cube, or CDT were not able to discriminate between NC and MCI groups. In dementia detection, the CDT had the highest diagnostic accuracy (sensitivity 76.6% and specificity 87.4%) followed by infinity loops (sensitivity 63.8% and specificity 91.6%) and cube (sensitivity 93.6% and specificity 46.3%). Conclusion. This study demonstrates that the three drawing tests are sensitive detectors of dementia but not MCI.
