ABSTRACT

Background@#Texture analysis may capture subtle changes in the gray matter more sensitively than volumetric analysis. We aimed to investigate the patterns of neurodegeneration in semantic variant primary progressive aphasia (svPPA) and Alzheimer’s disease (AD) by comparing the temporal gray matter texture and volume between cognitively normal controls and older adults with svPPA and AD. @*Methods@#We enrolled all participants from three university hospitals in Korea. We obtained T1-weighted magnetic resonance images and compared the gray matter texture and volume of regions of interest (ROIs) between the groups using analysis of variance with Bonferroni posthoc comparisons. We also developed models for classifying svPPA, AD and control groups using logistic regression analyses, and validated the models using receiver operator characteristics analysis. @*Results@#Compared to the AD group, the svPPA group showed lower volumes in five ROIs (bilateral temporal poles, and the left inferior, middle, and superior temporal cortices) and higher texture in these five ROIs and two additional ROIs (right inferior temporal and left entorhinal cortices). The performances of both texture- and volume-based models were good and comparable in classifying svPPA from normal cognition (mean area under the curve [AUC] = 0.914 for texture; mean AUC = 0.894 for volume). However, only the texture-based model achieved a good level of performance in classifying svPPA and AD (mean AUC = 0.775 for texture; mean AUC = 0.658 for volume). @*Conclusion@#Texture may be a useful neuroimaging marker for early detection of svPPA in older adults and its differentiation from AD.

ABSTRACT

Background@#This study was conducted to examine the effect of adverse childhood experiences on depressive symptoms in university students and to verify whether positive psychological resources act as a protective factor for depression. @*Methods@#Data from 1,317 young adults aged 18-29 years who took part in the university-based cross-sectional survey were analyzed. All participants completed self-report questionnaires that included demographic variables, the Adverse Childhood Experience (ACE) Scale, the Patient Health Questionnaire-9, and the Positive Resources Test. @*Results@#The incidence of depression was 33.3% and was higher in women than in men. Based on the 10 ACE categories, 32.7% of the students reported one or more adverse childhood experiences, and 14.4% reported two or more forms of adverse childhood experiences. Students with depressive symptoms were likely to report more traumatic experiences in childhood and fewer positive psychological resources than those without depressive symptoms. Hierarchical regression analysis indicated that positive psychological resources moderated the relationship between adverse childhood experiences and depression. @*Conclusion@#Based on these results, professionals should consider identifying adverse childhood experiences early and provide active mental health service support, including positive psychological and social resources for individuals who have adverse experiences during childhood.

ABSTRACT

Objective@#The purpose of this study was to explore the accuracy of expectation of medical lethality and to identify characteristics related to high medical lethality in suicide attempters. @*Methods@#A total of 370 suicide attempters (173 men, 197 women) who visited the emergency department at one university hospital were interviewed. @*Results@#Using the Lethality Scale, 103 (27.8%), 114 (30.8%), and 153 (41.4%) suicide attempters were assigned to the low, medium, and high medical lethality groups, respectively. The medium and high medical lethality groups were older, and reported poorer socioenvironmental conditions, compared with the low lethality group. Higher levels of suicide intent were associated with more lethal attempts but only for those attempters who had accurate expectations of the medical lethality of their attempts. @*Conclusion@#The accuracy of expectations about the likelihood of dying was found to moderate the relationships between suicide intent and medical lethality.

ABSTRACT

Objective@#Adverse childhood experiences (ACEs) are associated with negative physical and mental health outcomes across the lifespan, but research on intergenerational transmission of maternal ACEs and its impact on the offspring’s mental health problems are limited. The study examines the effects of maternal ACEs on the risk of internalizing or externalizing problems among offspring. @*Methods@#There were 450 mother-child dyads. Mothers completed the Adverse Childhood Experiences Questionnaire. The child outcomes included internalizing and externalizing problems assessed by the Korean Child Behavior Checklist (K-CBCL) and Korean Youth Self-Report (K-YSR), depression assessed by the Center for Epidemiological Studies Depression Scale for Children (CES-DC) and anxiety assessed by the Screen for Child Anxiety Related Emotional Disorders (SCARED). @*Results@#36.1% of mothers experienced at least one ACE, and 11.1% experienced three or more ACEs. Cumulative maternal ACEs were associated with internalizing problems, externalizing problems, depression and anxiety in the offspring. Household dysfunction from maternal ACEs was significantly associated with delinquent behavior, anxiety/depression, and somatic complaints in the offspring. @*Conclusion@#The findings support the hypothesis that maternal ACEs are related to mental health problems in the offspring. Further research is needed to determine the factors mediating intergenerational transmission as well as intervention strategies to prevent ACEs and mental health problems in the offspring.

ABSTRACT

Background@#To address the high suicide rate in Korea, determining the suicidality risk factors is a key concern in policymaking and prevention. This study aimed to describe the effects of traumatic childhood experiences on suicidality among young adults. @*Methods@#This study included 1,379 subjects from two universities in Jeju, Korea. All participants completed selfadministered questionnaires that included demographic variables, the Adverse Childhood Experiences (ACE) scale to evaluate traumatic childhood experiences, and a Korean version of the Suicide Module of the Mini International Neuropsychiatric Interview to evaluate suicidality. @*Results@#Of the subjects, 33.2% reported experiencing traumatic childhood experiences, and the prevalence of positive suicidality was 21.8%. Regression analyses indicated a significant association between traumatic childhood experiences and positive suicidality after controlling for multiple variables. Furthermore, subjects with positive suicidality were likely to report experiencing more traumatic childhood experiences (p<0.001). After categorizing the subjects into two groups according to ACE score, the positive ACE group showed a higher risk of suicidal ideation (p<0.001, adjusted odds ratio [AOR]=2.09) and suicidal attempt (p<0.001, AOR=4.15) than those negative ACE. @*Conclusion@#Intervention and practical strategies for college students with a history of traumatic childhood experiences must be considered for suicide prevention.

ABSTRACT

Objectives@#Adverse childhood experiences (ACEs) of mothers may negatively affect the mental health of their offspring. Little is known about the intergenerational effect of maternal ACE on post-traumatic stress disorder (PTSD) in the offspring. This study investigated the impact of maternal ACEs on PTSD in the offspring. @*Methods@#A total of 156 mothers with children aged 13–18 years completed the Diagnostic Interview Schedule for Children (DISC) Predictive Scales to determine the presence of psychiatric disorders in their offspring. The subjects completed the ACE questionnaire and the Early Trauma Inventory Self-Report-Short Form. Multivariable logistic regression was used to analyze the relationship between maternal ACEs and PTSD in the offspring. @*Results@#Of the mothers, 23.7% had at least one ACE, and PTSD was reported in 21.8% of the offspring. The offspring of the mothers in the ACE group had a significantly higher rates of traumatic experiences and PTSD than the offspring of the mothers in the no ACE group. Maternal household dysfunction independently predicted offspring PTSD [odds ratio (OR)=3.008, p=0.05), and three or more maternal ACEs were significantly related to PTSD in the offspring (OR=10.613, p=0.025). @*Conclusion@#Maternal ACEs have a significant impact on the risk of traumatic experiences and PTSD in the offspring. These findings suggest the presence of intergenerational transmissions by which maternal ACEs affect the mental health of the offspring.

ABSTRACT

Objective@#We investigated the frequency of depressive disorders in the elderly with normal cognition (NC), mild cognitive impairment (MCI) and dementia patients living in the community to find out the association between cognitive disorders and depressive disorders in the community dwelling elderly. @*Methods@#6,262 baseline study subjects from November 2010 through October 2012 were enrolled based on the Korean longitudinal study on cognitive aging and dementia which is the first nationwide multi-center population based prospective cohort study in Korea. Diagnosis of MCI, dementia, major depressive disorder (MDD), minor depressive disorder (mDD) and subsyndromal depression (SSD) was made by psychiatrists with expertise in dementia based on the appropriate diagnostic criteria. @*Results@#4,303 NC, 1,737 MCI, 222 dementia were enrolled. The frequency of MDD, mDD, SSD were highest in dementia and lowest in NC and showed significant difference among three groups. The odds ratio also increased significantly in MCI and dementia compared with NC showing highest odds ratio in dementia. @*Conclusion@#Our findings propose that MCI and dementia in the community dwelling elderly were significantly associated with various types of depressive disorders showing highest association tendency in dementia.

ABSTRACT

Objective@#Cardiovascular diseases are representative risk factors for the onset of cognitive decline. The purpose of this study was to confirm the relationship between diastolic blood pressure and cognitive function in elderly people in Korea. @*Methods@#Data from subjects who were enrolled in the prospective Korean Longitudinal Study on Cognitive Aging and Dementia were used in this study. Data from 701 subjects whose diastolic blood pressure range did not change (≤79 mm Hg or ≥80 mm Hg) over 2 years were analyzed. To analyze the differences in cognitive function between the groups at the 2-year follow-up, an analysis of covariance was performed with covariates, which were significantly different between the two groups, and the baseline cognitive function. @*Results@#Significant differences were observed between the two groups, and the mean scores on the constructional praxis (η2=0.010) and word list recall tests (η2=0.018) in the diastolic blood pressure ≥80 mm Hg group were higher than those in the diastolic blood pressure ≤79 mm Hg group at the 2-year follow-up. @*Conclusion@#These results indicate that maintaining a DBP below 79 mm Hg presents a greater risk of cognitive decline in Korean elderly people.

ABSTRACT

Objective@#This study estimated the incidence of driving-related adverse events and examined the association of cognitive function with the risk of future driving-related adverse events in the elderly Korean male population. @*Methods@#We analyzed 1,172 male drivers aged 60 years or older in the Korean Longitudinal Study on Cognitive Aging and Dementia (KLOSCAD). Using the data from Korean National Police Agency, we classified the participants into three groups: safe driving (drove for 2 years after baseline without a traffic accident or repeated violations), driving cessation (stopped driving), and risky driving (one or more traffic accidents or repeated violations). We estimated the incidences of driving cessation and risky driving, and examined the effect of cognitive function on their risks. @*Results@#The incidence of driving cessation and risky driving in the Korean male drivers aged 60 years or older was 19.3 and 69.9 per 1,000 person-years respectively and increased in the late 80s. Drivers with better baseline Word List Memory Test scores showed less risky driving (OR=0.94, p=0.039). @*Conclusion@#Driving-related adverse events increased in late 80s, and better memory function was protective against these events.

ABSTRACT

Infectious diseases of immigrant populations have recently become important issues for the health of both Korean nationals and foreigners living in Korea. This case report of general paresis is intended to raise awareness about re-emerging neurosyphilis in Korea as a possible etiology of psychotic disorders. A 68-year-old male Chinese resident came to Korea in 2019 with disorientation, auditory hallucination, persecutory delusion, and aggressive behavior, and was admitted to a psychiatric ward for further evaluation and treatment via the emergency department. He was confirmed to have neurosyphilis by serum test, analysis of cerebrospinal fluid, and brain magnetic resonance imaging. After treatment with antibiotics, including intravenous penicillin, in combination with atypical antipsychotics for 6 weeks, his disorientation, auditory hallucination, delusion, and aggressive behavior had attenuated.Neurosyphilis should still be included as a possible etiology of psychotic disorders in Korea.At the initial evaluation, syphilis screening serum tests are recommended for psychotic patients, especially those with pleomorphic symptoms and cognitive dysfunction.

ABSTRACT

OBJECTIVES@#Most studies on post-traumatic stress disorder (PTSD) have involved a small sample size and a specific traumatic event, with few studies reporting on subjects who have been continuously exposed to a traumatic event. Timely assessment and treatment are crucial for individuals chronically exposed to a traumatic event. Therefore, this study investigated the prevalence of PTSD and associated factors in all residents of Gangjeong village, who, recently, have been exposed to a traumatic event for a prolonged period.@*METHODS@#The subjects of this study were the residents of Gangjeong village, who have been exposed to a traumatic event related to the construction of the Jeju Civilian-Military Complex Port. The survey included items related to general characteristics and PTSD symptoms, which were assessed using the Impact of Event Scale-Revised, Korean version.@*RESULTS@#The prevalence of PTSD symptoms was 26.8% (95% confidence interval=23.54–30.04). Multivariate logistic regression analysis identified age, length of residence, and marital status as factors significantly associated with PTSD symptoms.@*CONCLUSION@#The prevalence of PTSD symptoms was higher among the study population than in the general population. Economically active age groups, people exposed to the traumatic event throughout their duration of residence in the village, and unmarried individuals were found to be more likely to develop PTSD symptoms. Mental, social, and financial support should be directed to the affected groups of individuals.

ABSTRACT

OBJECTIVE: We investigated the impact of depressed mood (dysphoria) and loss of interest or pleasure (anhedonia)on the risk of dementia in cognitively-normal elderly individuals. METHODS: This study included 2,685 cognitively-normal elderly individuals who completed the baseline and 4-year follow-up assessments of the Korean Longitudinal Study on Cognitive Aging and Dementia. We ascertained the presence of dysphoria and anhedonia using the Mini International Neuropsychiatric Inventory. We defined subjective cognitive decline as the presence of subjective cognitive complaints without objective cognitive impairments. We analyzed the association of dysphoria and anhedonia with the risk of cognitive disorders using multinomial logistic regression analysis adjusted for age, sex, education, Cumulative Illness Rating Scale score, Apolipoprotein E genotype, and neuropsychological test performance. RESULTS: During the 4-year follow-up period, anhedonia was associated with an approximately twofold higher risk of mild cognitive impairment (OR=2.09, 95% CI=1.20–3.64, p=0.008) and fivefold higher risk of dementia (OR=5.07, 95% CI=1.44–17.92, p=0.012) but was not associated with the risk of subjective cognitive decline. In contrast, dysphoria was associated with an approximately twofold higher risk of subjective cognitive decline (OR=2.06, 95% CI=1.33–3.19, p=0.001) and 1.7-fold higher risk of mild cognitive impairment (OR=1.75, 95% CI=1.00–3.05, p=0.048) but was not associated with the risk of dementia. CONCLUSION: Anhedonia, but not dysphoria, is a risk factor of dementia in cognitively-normal elderly individuals.

ABSTRACT

OBJECTIVE: This study aimed to examine the association between normal-but-low folate levels and cognitive function in the elderly population using a prospective cohort study. METHODS: We analyzed 3,910 participants whose serum folate levels were within the normal reference range (1.5–16.9 ng/mL) at baseline evaluation in the population-based prospective cohort study named the “Korean Longitudinal Study on Cognitive Aging and Dementia.” The association between baseline folate quartile categories and baseline cognitive disorders [mild cognitive impairment (MCI) or dementia] was examined using binary logistic regression analysis adjusting for confounding variables. The risks of incident MCI and dementia associated with the decline of serum folate level during a 4-year follow-up period were examined using multinomial logistic regression analysis. RESULTS: The lowest quartile group of serum folate (≥1.5, ≤5.9 ng/mL) showed a higher risk of cognitive disorders than did the highest quartile group at baseline evaluation (odds ratio 1.314, p=0.012). Over the 4 years of follow-up, the risk of incident dementia was 2.364 times higher among subjects whose serum folate levels declined from the 2nd–4th quartile group to the 1st quartile than among those for whom it did not (p=0.031). CONCLUSION: Normal-but-low serum folate levels were associated with the risk of cognitive disorders in the elderly population, and a decline to normal-but-low serum folate levels was associated with incident dementia. Maintaining serum folate concentration above 5.9 ng/mL may be beneficial for cognitive status.

ABSTRACT

Our study aimed to analyze the clinical characteristics and psychotropic prescription patterns of a history of suicide attempts in South Koreans with bipolar disorder (BD), by using only Korean data from the Research on Asian Psychotropic Prescription Pattern for Bipolar disorder. The patterns of clinical characteristics and psychotropic drug use were compared among 53 patients with a history of suicide attempts and 297 without this history; the potential effects of confounding variables were adjusted with binary logistic analyses for discrete variables and analyses of covariance for continuous variables. After adjusting the effects of age, sex, duration of illness, and enrollment as an outpatient, patients with a history of suicide attempts were characterized by a significantly more prevalent depressive episode, lower prevalent remission state, lower levels of hemoglobin, and more use of antidepressants, anxiolytics, and hypnotics compared to those without lifetime suicide attempt. The inability to plan goal-directed behavior may be an intervening factor in the relationship between suicide attempts and depression in BD. Relatively low hemoglobin levels can be associated with manic episodes in patients with a history of suicide attempts and the use of antidepressants, anxiolytics, or hypnotics can be associated with suicide attempts in BD patients.

ABSTRACT

OBJECTIVE: Declines in naming ability and semantic memory are well-known features of early Alzheimer's disease (AD). We developed a new screening algorithm for AD using two brief language tests : the Categorical Fluency Test (CFT) and 15-item Boston Naming Test (BNT15). METHODS: We administered the CFT, BNT15, and Mini-Mental State Examination (MMSE) to 150 AD patients with a Clinical Dementia Rating of 0.5 or 1 and to their age- and gender-matched cognitively normal controls. We developed a composite score for screening AD (LANGuage Composite score, LANG-C) that comprised demographic characteristics, BNT15 subindices, and CFT subindices. We compared the diagnostic accuracies of the LANG-C and MMSE using receiver operating curve analysis. RESULTS: The LANG-C was calculated using the logit of test scores weighted by their coefficients from forward stepwise logistic regression models : logit (case)=12.608−0.107×age+1.111×gender+0.089×education−0.314×HS(1st)−0.362×HS(2nd)+0.455×perseveration+1.329×HFCR(2nd)−0.489×MFCR(1st)−0.565×LFCR(3rd). The area under the curve of the LANG-C for diagnosing AD was good (0.894, 95% confidence interval=0.853–0.926 ; sensitivity=0.787, specificity=0.840), although it was smaller than that of the MMSE. CONCLUSION: The LANG-C, which is easy to automate using PC or smart devices and to deliver widely via internet, can be a good alternative for screening AD to MMSE.

ABSTRACT

OBJECTIVE: Purpose of this study was to assess the potential added values of Subjective Memory Complaint Questionnaire (SMCQ) combined with Mini-Mental State Examination (MMSE) in developing a brief screening battery to improve the early detection rate of dementia in community setting. METHODS: Non-depressed community-dwelling Korean elderly aged 65 years and older who 945 randomly selected and 734 voluntarily involved were recruited. Dementia was diagnosed using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. Diagnostic ability of 10 point SMCQ subscale for everyday memory (SMCQ-E) for dementia was evaluated. Additive values of SMCQ-E combined with MMSE for dementia screening and the economic benefits of SMCQ-E and its combination with MMSE were also evaluated. RESULTS: Overall area under the curve values of SMCQ-E were 0.605 (0.565–0.646) for nonrandom sample and 0.836 (0.783–0.890) for random sample. When SMCQ-E was combined with MMSE using ‘AND’ rule, accuracy, specificity, positive predictive values and positive likelihood ratio were increased than those of MMSE. While SMCQ-E was combined the MMSE using ‘OR’ rule, sensitivity and negative predictive values were increased and negative likelihood ratio were decreased than those of SMCQ-E and MMSE. When SMCQ-E and MMSE combined with AND rule, total cost for dementia screening was reduced to about 80% compared to MMSE single use model. CONCLUSION: Results of this study showed that brief SMCQ-E and its combination with MMSE could be used to dementia screening with cost effective manner.

ABSTRACT

BACKGROUND: Social anxiety and suicide are serious common problems in college students. However, there are few studies on the relationship between social anxiety symptoms and suicidal risk. Therefore, we evaluated the associationbetween social anxiety symptoms and suicidal risk in college students.METHODS: A total of 579 college students were recruited for a college-based cross-sectional survey in the Jeju area. The participants completed a questionnaire gathering sociodemographic information; they also completed the Korean Social Avoidance and Distress Scale (SADS) to assess social anxiety symptoms and the Center for Epidemiologic Studies Depression Scale (CES-D) to assess depressive symptoms. To obtain information regarding suicidal risk, we administered the Korean version of the Suicide module of the Mini International Neuropsychiatric Interview (M.I.N.I.).RESULTS: The prevalence of higher levels of social anxiety symptoms among college students was 28.0% (n=162). A higher level of social anxiety symptoms resulted in a 2.10-times higher suicidal risk after adjusting for depression in college students (95% confidence interval, 1.05-4.23; p=0.037).CONCLUSION: Based on the results of this study, social anxiety symptoms should be managed and controlled to prevent suicidality in Korean college students.

ABSTRACT

OBJECTIVE: Due to an unprecedented rate of population aging, South Korea is facing a dementia epidemic. For this reason, the Korean Longitudinal Study on Cognitive Aging and Dementia (KLOSCAD) was launched in 2009 with support from the Korean Health Industry Development Institute to investigate the epidemiology, biopsychosocial risk factors, and outcomes of dementia and dementia-related conditions. METHODS: The KLOSCAD is the first nationwide multi-center population-based prospective cohort study. In October 2010, 12,694 individuals were randomly sampled from residents aged 60 years or older who lived in 13 districts across South Korea. In the baseline assessment, which was conducted from November 2010 through October 2012, 6,818 (53.7%) individuals participated. Follow-up assessments have been conducted every two years, with the first follow-up assessment conducted between November 2012 and October 2014, and the second between November 2014 and October 2016. The third is now in progress, and will span from November 2016 to October 2018. Diagnosis of cognitive disorders, neuropsychological battery, behavioral and psychological symptoms of dementia, activities of daily living, physical and neurologic examination and laboratory tests, life styles, quality of life, and identification of death were evaluated in each assessment. RESULTS: The cumulative drop-out rate at the second follow-up assessment was 38.7%. Dementia and mild cognitive impairment were 5.0% and 27.0%, respectively. CONCLUSION: The KLOSCAD may provide strong scientific evidence for advancing the fight against dementia both in Korea and globally.

ABSTRACT

OBJECTIVE: We investigated the prevalence and risk factors of physically abusive behaviors (PhAB) and psychologically abusive behaviors (PsAB) towards people with dementia (PWD) in family caregivers, and compared their prevalences between East Asian and Western countries. METHODS: We estimated the prevalence and risk factors of PhAB and PsAB in 467 Korean pairs of community-dwelling PWD and their primary family caregivers. We evaluated abusive behaviors using the Modified Conflict Tactics Scale. In addition, we compared the prevalence of abusive behaviors between Asian and Western countries through a meta-analysis on 12 studies including the current one. RESULTS: More than a half of the caregivers reported PsAB and about one out of seven caregivers admitted PhAB within past three months. PsAB and PhAB were slightly more prevalent in East Asian countries than in Western countries. Non-Alzheimer type and moderate to severe behavioral and psychological symptoms of dementia were associated with the risk of PhAB but not with the risk of PsAB. Severe care burden and low income were associated with the risk of PhAB and PsAB. CONCLUSION: PhAB and PsAB were as prevalent in the family caregivers of PWD in Asian countries including Korea as in Western countries. Prevention strategies should be implemented according to the type of abusive behaviors.
