Background:
and Purpose: The Montreal Cognitive Assessment (MoCA) has been known as a screening test for detecting mild cognitive impairment (MCI) better than Mini-Mental State Examination (MMSE). However, in previous domestic studies, no significant difference was found in the discriminability between MoCA and MMSE. Researchers have suggested that this might be because older Koreans are less educated than older Westerners. This study was conducted to examine the effect of education on the discriminability of MoCA compared to the MMSE.
Methods:
Participants were 123 cognitively normal elderly, 118 with vascular MCI, 108 with amnestic MCI, 121 with vascular dementia, and 113 with dementia of the Alzheimer’s type.The Korean-MoCA (K-MoCA) and Korean-MMSE (K-MMSE) were administered. Multiple regression analyses and receiver operating characteristic (ROC) curve analyses were performed.
Results:
In all participants, education significantly affected both K-MoCA and K-MMSE scores along with age. The effect of education was re-examined by subgroup analysis after dividing subjects according to the level of education. Effect of education on K-MoCA and K-MMSE was only shown in the group with <9 years of education. ROC curve analyses revealed that the discriminability of K-MoCA to differentiate between vascular MCI and normal elderly was significantly higher than that of K-MMSE. When re-examining subgroups divided by education level, however, this higher discriminability of K-MoCA disappeared in the group with <9 years of education.
Conclusions
These results indicate no difference in discriminating cognitive deficits between K-MoCA and K-MMSE in Korean elderly with <9 years of education.

Background:
and Purpose: Empathy comprises cognitive and emotional components.However, the impairments in empathy among individuals with mild cognitive impairment (MCI) and dementia of the Alzheimer’s type (DAT) are not well understood, particularly in the context of depression, which may exacerbate these deficits. This study aimed to evaluate the effects of neurodegeneration and depression on empathetic abilities.
Methods:
The study included 31 healthy elderly (HE) individuals, 30 patients with amnestic multi-domain MCI (amMCI), and 30 patients with DAT. Empathy was assessed using the Korean-Multifaceted Empathy Test (K-MET), and the Interpersonal Response Index (IRI).Participants were classified as depressed or non-depressed using the Geriatric Depression Scale. A two-way MANOVA was conducted to examine differences in empathy based on group and depressive status.
Results:
A significant interaction between group and depressive status was found for both cognitive and emotional empathy on the K-MET, but not on the IRI. In the depressed group, cognitive empathy scores were lower in the order of HE, amMCI, and DAT. Similarly, in the non-depressed group, the HE group performed better than both amMCI and DAT, with no significant difference between the latter two. Regarding emotional empathy, the depressed HE group scored higher than both amMCI and DAT, with no significant difference between these groups. In the non-depressed group, emotional empathy declined in the order of HE, amMCI, and DAT.
Conclusions
These findings indicate that both neurodegeneration and depression significantly impair empathetic abilities, with declines in cognitive and emotional empathy evident at the MCI stage, regardless of depressive status.

We aimed to validate the Inventory of Complicated Grief (ICG)-Korean version among 1,138 Korean adolescents, representing a response rate of 57% of 1,997 students. Participants completed a set of questionnaires including demographic variables (age, sex, years of education, experience of grief), the ICG, the Children's Depression Inventory (CDI) and the Lifetime Incidence of Traumatic Events-Child (LITE-C). Exploratory factor analysis was performed to determine whether the ICG items indicated complicated grief in Korean adolescents. The internal consistency of the ICG-Korean version was Cronbach's alpha=0.87. The test-retest reliability for a randomly selected sample of 314 participants in 2 weeks was r=0.75 (P<0.001). Concurrent validity was assessed using a correlation between the ICG total scores and the CDI total scores (r=0.75, P<0.001). The criterion-related validity based on the comparison of ICG total scores between adolescents without complicated grief (1.2±3.7) and adolescent with complicated grief (3.2±6.6) groups was relatively high (t=5.71, P<0.001). The data acquired from the 1,138 students was acceptable for a factor analysis (Kaiser-Meyer-Olkin Measure of Sampling Adequacy=0.911; Bartlett's Test of Sphericity, chi2=13,144.7, P<0.001). After omission of 3 items, the value of Cronbach's alpha increased from 0.87 for the 19-item ICG-Korean version to 0.93 for the 16-item ICG-Korean version. These results suggest that the ICG is a useful tool in assessing for complicated grief in Korean adolescents. However, the 16-item version of the ICG appeared to be more valid compared to the 19-item version of the ICG. We suggest that the 16-item version of the ICG be used to screen for complicated grief in Korean adolescents.
