RESUMO
The onset of many lifelong mental illnesses is during childhood and adolescence. There has been an increase in these conditions among children and adolescents especially, during the COVID-19 pandemic. It is essential to promote mental health literacy (MHL) as a preventive and universal intervention for children and adolescents. Positive mental health status in adolescence is related to an increased level of MHL, and various MHL programs at schools have been reported to be effective for adolescent students worldwide. Recently, MHL programs have been developed in South Korea to be used by schoolteachers. There is a need for active dissemination and development of future programs. For continuous and effective education, it is desirable to include MHL education in regular school curricula.
RESUMO
The coronavirus disease 2019 (COVID-19) pandemic is profoundly affecting human life around the world. While the mental health of patients and quarantined is of increasing concern, the general public’s mental health also requires significant attention. COVID-19 also has the potential to threaten the mental health of children and adolescents significantly. This paper reviews the effects of the pandemic on the mental health of the general public, including children and adolescents. The risk factors for mental health problems are also reviewed. South Korea has implemented preemptive and aggressive quarantine measures against COVID-19. Mental health professionals have performed various psychological services to support the general public immediately and actively. This paper presents those supporting measures and discusses their limitations. Recognizing the importance of the impact of the pandemic on the mental health of the general public, observing its direct and indirect consequences, and organizing a multi-disciplinary system based on empathy and collaboration are important for developing effective support measures. In particular, national policies and support are needed to implement them.
RESUMO
OBJECTIVE: Previous studies showing the association of exposure to peer (PeVA) and parental verbal abuse in childhood with structural alterations in the young adult brain suggest functional changes in adolescence. In this functional MRI study, we investigated the effects of exposure to PeVA, during elementary and middle school periods, on brain response to emotional words, in high school students. METHODS: An emotional Stroop task consisting of swear, negative, positive, and neutral words was performed during functional MRI scan for 23 subjects who were divided into low- and high exposure groups to PeVA. RESULTS: High-PeVA group had a higher depression score, greater left ventrolateral prefrontal cortex (VLPFC) activity, and higher left VLPFC-left hippocampus connectivity in swear word conditions. The VLPFC activity and left VLPFC-left hippocampus connectivity was negatively related to the severity of anxiety and depressive symptoms, respectively. CONCLUSION: These preliminary findings support the hypothesis that exposure to PeVA, during childhood, is an aversive stimulus associated with meaningful functional change in emotional regulation network, showing hypersensitivity to swear words, at middle adolescence.

OBJECTIVES: Symptoms of attention-deficit hyperactivity disorder (ADHD) during childhood may persist into adulthood. This study included the development and validation process of the Korean Adult ADHD Rating Scale (K-AARS), which was developed for screening and monitoring treatment of adults with ADHD. METHODS: Preliminary questionnaires of the K-AARS were based on the reviews of previous adult ADHD scales and clinical experiences of the board certified child and adolescent psychiatrists in Korea. For this study, 136 adults (18-50 years old) with inattention, hyperactivity and/or impulsivity symptoms were enrolled as ADHD subjects, and compared with 406 control subjects (18-50 years old) without ADHD symptoms. Construct validity was examined using explorative factor analysis and Cronbach's alpha to obtain internal reliability coefficients. Concurrent validity was evaluated by comparison with the Conners' Adult ADHD Rating Scale (CAARS). RESULTS: An explorative factor analysis showed that the K-AARS had 8 factors (inattention, hyperactivity, impulsivity, antisocial personality disorder/conduct disorder/oppositional defiant disorder, impairment, driving, emotional dysregulation, disorganization). K-AARS was highly reliable in terms of internal consistency (Cronbach's alpha 0.77-0.95) and correlation between factors (0.57-0.86). Concurrent validity with the CAARS and discriminant validity were statistically significant. CONCLUSION: The K-AARS is a valid and reliable measure for assessment of Korean adults with ADHD.

OBJECTIVE: The aim of the present study was to examine the psychometric properties of the Korean Verbal Abuse Questionnaire (K-VAQ) that consists of 15 items related with life-time verbal aggression exposure. METHODS: A total of 5814 university students who agreed to take part in the study completed the K-VAQ, the Korean version of the Life Event CheckList (LEC-K) and Impact of Event Scale-Revised (K-IES-R). Internal consistency was checked by using item-total item correlation and Cronbach's alpha coefficient. Exploratory and confirmatory factor analyses were performed, and convergent and concurrent validity levels were examined. Finally, a cluster analysis was conducted to verify the validity of the cutoff point of the K-VAQ. RESULTS: The Cronbach's alpha correlation coefficient was 0.9. The K-VAQ showed a single factor structure which explained 55.34% of the total variance. The K-VAQ was significantly associated with the LEC-K (r=0.24) and K-IES-R (r=0.28), indicating good convergent validity and concurrent validity. The cluster analysis provided four clusters of trauma experiences: high, moderate, low, and minimal, with K-VAQ ranges of 43-81, 20-42, 7-19, and 0-6, respectively. In a further investigation, a K-VAQ score of 40 was found to be the appropriate cutoff point to delineate the highly verbally abused group, as used in the previous studies. A sum of 36.5% of the highly verbally abused group reported to show substantial symptoms of PTSD (K-IES-R score >22). CONCLUSION: The present findings suggest that the K-VAQ has good psychometric properties for assessing verbal aggression among the Korean population.

This review examined the treatment of attention-deficit/hyperactivity disorder (ADHD) in adults. It briefly addresses the issues about the cause of hospital visit, diagnosis, and impact of disease, specific to adults. The article focused on the evidence regarding the efficacy and tolerability of short- and long-acting stimulant medications, as well as the non-stimulant medications such as atomoxetine and bupropion in the treatment of the adult ADHD. Generally speaking, variability in diagnostic criteria, dosing parameters and response rates between the various studies were considerable. The aggregated literature shows that both the stimulants and non-stimulants had clinically significant beneficial effect on treating ADHD in adults. Special attention is given to the pharmacological treatment for patients with adult ADHD and various comorbidities. In summary, medications are effective and combined medication and psychosocial treatment is the most beneficial treatment option for most adult patients with ADHD.

OBJECTIVES: Abnormalities in various subcortical regions have been reported in previous structural neuroimaging studies for schizophrenia. To understand the subcortical abnormalities as a whole, all subcortical regions should be explored in each subject unlike most previous studies. Here, we explored major subcortical structures using volume measurement and shape analysis for schizophrenic patients (SZ), their unaffected siblings (Sib) and healthy controls without affected sibling (HC). METHODS: Structural magnetic resonance images were acquired from 24 SZ, 24 Sib and 19 HC. Both segmentation and shape analysis for subcortical structures was performed using FMRIB Integrated Registration and Segmentation Tool integrated within the FSL software. The group comparison of subcortical volumes was performed with multivariate analysis of variance (MANOVA). RESULTS: In SZ group, shape deformities were observed in the left nucleus caudates, left thalamus, left putamen and bilateral pallidus were increased compared with HC group. In Sib group, shape deformities were observed in the left pallidus, left putamen and left putamen was decreased compared with HC group. In Sib group, left nucleus accumbens was increased compared with SZ group. CONCLUSION: The result of this study using volume measurement and shape analysis suggest that subcortical structural abnormalities in cortico-striato-pallido-thalamic and reward circuits are related with both the pathology of schizophrenia and genetic predisposition.

OBJECTIVES: Characteristic symptoms, including hyperactivity and easy distractibility, in children with attention-deficit hyperactivity disorder (ADHD) suggest that their brain status, even at rest, might differ from that of healthy children. This study was conducted in order to determine whether resting state brain activity is compromised in medication-naive children with ADHD. METHODS: Twenty medication-naive children with ADHD (mean age 10.3+/-2.5) and 28 age- and gender-matched healthy volunteers (mean age 10.3+/-2.0) underwent measurements for resting state brain activity using functional magnetic resonance imaging (fMRI). Among resting state related-independent components (RSICs) extracted from fMRI data using independent component analysis, a significant difference in RSICs was observed between groups, using a mixed Gaussian/gamma model. RESULTS: Except for IQ, which was higher in the healthy control group, no demographic difference was observed between the two groups (p<.001). Significantly less activation of one RSIC, which includes the bilateral precuneus/posterior cingulate cortex, occipito-temporal junction, and anterior cingulate cortex, was observed in the ADHD group, compared with the control group (p<.05). CONCLUSION: An abnormal RSIC, posterior default mode network (DMN), was observed in the medication-naive ADHD group. Results of our study suggest that abnormality of posterior DMN is one of the main pathophysiologies of ADHD.

OBJECTIVE: Resting-state networks (RSNs), including the default mode network (DMN), have been considered as markers of brain status such as consciousness, developmental change, and treatment effects. The consistency of functional connectivity among RSNs has not been fully explored, especially among resting-state-related independent components (RSICs). MATERIALS AND METHODS: This resting-state fMRI study addressed the consistency of functional connectivity among RSICs as well as their spatial consistency between 'at day 1' and 'after 4 weeks' in 13 healthy volunteers. RESULTS: We found that most RSICs, especially the DMN, are reproducible across time, whereas some RSICs were variable in either their spatial characteristics or their functional connectivity. Relatively low spatial consistency was found in the basal ganglia, a parietal region of left frontoparietal network, and the supplementary motor area. The functional connectivity between two independent components, the bilateral angular/supramarginal gyri/intraparietal lobule and bilateral middle temporal/occipital gyri, was decreased across time regardless of the correlation analysis method employed, (Pearson's or partial correlation). CONCLUSION: RSICs showing variable consistency are different between spatial characteristics and functional connectivity. To understand the brain as a dynamic network, we recommend further investigation of both changes in the activation of specific regions and the modulation of functional connectivity in the brain network.

Neuroimaging studies in schizophrenia have remarkably increased and provided some clues to understand its pathophysiology. Here, we reviewed the neuroimaging, studies including volume analysis, functional magnetic resonance imaging (MRI) and diffusion tensor imaging, and findings in both early stage schizophrenia and high-risk group. The reviewed studies suggested that the brain with schizophrenia showed both regional deficits and dysconnectivity of neural circuit in the first episode, even high-risk group as well as chronic schizophrenia. Multimodal neuroimaging or combined approach with genetic, electro- or magneto-encephalographic data could provide promising results to understand schizophrenia in the near future.

OBJECTIVE: Emoticon as well as face is a tool for the communication of emotion. However, little is known about behavioral response to emoticon, unlike face. To explore the characteristics of behavioral response of emoticon and face, we measured both response time and accuracy in healthy young subjects. METHODS: The 29 subjects were asked to respond to emoticons or faces which contained one among happy, sad, angry/fearful or neutral emotion. Using univariate analysis of variance, behavioral responses were analyzed for three main effects of stimulation (face, emoticon), emotion (happy, sad, angry/fearful, neutral), gender (male, female) and also their interactions. RESULTS: The response to face was faster and more accurate than that to emoticon. Female's response to face, not to emoticon, was faster than male. A common finding of face and emoticon stimuli was that their responses were slower and less accurate in angry/fearful condition than in the rest emotional ones. There was not any interaction among three factors. The different finding was that neutral condition was less informative in only emoticon, not in face, condition. CONCLUSION: Our results demonstrated emoticon is different from face in terms of the characteristics in the transfer ability of emotion and in gender effect.

OBJECTIVE: The purpose of this study was to compare the discontinuation rate of widely prescribed atypical antipsychotics when administered to newly admitted, acutely ill patients with schizophrenia or bipolar mania. METHODS: Medical records of patients admitted to psychiatric ward of two university hospitals between January 2007 and December 2008 were retrospectively reviewed. Subjects were eligible for inclusion if they prescribed olanzapine, risperidone or aripiprazole for their psychotic or manic symptom control. Patient groups (olanzapine/risperidone/aripiprazole) were compared for rate of antipsychotics discontinuation and duration of treatment continuation. RESULTS: There was no statistically significant difference in the rates of discontinuation during hospitalized period between olanzapine, risperidone and aripiprazole. Rates of discontinuation were 14.5% for olanzapine, 18.6% for aripiprazole and 24.0% for risperidone. Predictor of treatment discontinuation was short titration period and long illness duration. CONCLUSION: This study demonstrated that risperidone, olanzapine and aripiprazole were comparable with no difference found on the discontinuation rate in treating acutely ill psychiatric patients. However, the small number of patients who participated in this study made it difficult to establish significance.

OBJECTIVES: Occipito-temporal connectivity was explored using diffuse tensor imaging (DTI) and its correlation to behavioral symptoms and neurocognitive functions in medication-naive attentiondeficit/hyperactivity disorder (ADHD) children and adolescents. METHODS: Eleven medication-naive children and adolescents with ADHD (mean age 11.5+/-.3) and 9 age- and gender-matched healthy volunteers (mean age 11.4+/-2.5) were measured for mean fractional anisotropy (FA) values with DTI and clinical assessments. The FA values for the region of interest (ROI) which contained both inferior longitudinal fasciculus (ILF) and inferior occipito-frontal fasciculus (IOFF), were compared in ADHD and gender- and age-matched healthy control groups and the relationship between clinical and neurocognitive variables was explored. RESULTS: The ADHD group exhibited significantly higher scores on the Korean ADHD Rating Scale (p<0.001), the Korean Conners Parent Rating Scale (p<0.001), the computerized Continuous Performance Test, and the Visual (omission error, commission error, mean time, and variability)(p<0.01), and significantly decreased scores on the Finger Window Test (p<0.01). Mean FA values from the left-side ROI were significantly lower in the ADHD group compared with healthy controls after controlling for age (p<0.05). In the ADHD group, FA values from the left-side of the ROI did not show significant correlation with clinical rating or neurocognitive tests. CONCLUSION: Our results suggest that one of the core pathophysiology hallmarks in child ADHD may be abnormal anatomical connectivity in the occipito-frontal and/or occipito-temporal pathway, both of which are related to visual information processing. To confirm such an anatomical deficit and its association with clinical or neurocognitive symptoms in ADHD, further studies using larger sample sizes are needed.

OBJECTIVE: Many studies have showed that excess or lack of sexual hormones, such as prolactin and testosterone, induced the sexual dysfunction in humans. Little, however, is known about the role of sexual hormones showing normal range in, especially, the basal state unexposed to any sexual stimulation. We hypothesized sexual hormones in the basal state may affect sexual behavior. METHODS: We investigated the association of the sexual hormones level in the basal hormonal state before visual sexual stimulation with the sexual response-related brain activity during the stimulation. Twelve heterosexual men were recorded the functional MRI signals of their brain activation elicited by passive viewing erotic (ERO), happy-faced (HA) couple, food and nature pictures. Both plasma prolacitn and testosterone concentrations were measured before functional MR scanning. A voxel wise regression analyses were performed to investigate the relationship between the concentration of sexual hormones in basal state and brain activity elicited by ERO minus HA, not food minus nature, contrast. RESULTS: The plasma concentration of prolactin in basal state showed positive association with the activity of the brain involving cognitive component of sexual behavior including the left middle frontal gyrus, paracingulate/superior frontal/anterior cingulate gyri, bilateral parietal lobule, right angular, bilateral precuneus and right cerebellum. Testosterone in basal state was positively associated with the brain activity of the bilateral supplementary motor area which related with motivational component of sexual behavior. CONCLUSION: Our results suggested sexual hormones in basal state may have their specific target regions or network associated with sexual response.

OBJECTIVES : A neural circuit including amygdala, the hippocampal complex and prefrontal cortex was associated with deficits in facial processing in schizophrenia. These deficits have a significant impact on social functioning in schizophrenia. Both neuropsychological deficits and brain structural abnormalities in first-degree relatives of schizophrenia patients suggest that they may also have the deficit in facial information processing as genetic factors. The purpose of this study was to explore the dysfunction of facial information processing in first-degree relatives of schizophrenia patients using functional magnetic neuroimaging (fMRI). METHODS : Ten non-affected siblings of schizophrenic patients and 10 normal comparison subjects having no schizophrenic siblings underwent fMRI during the d ynamic facial change procedure consisting of presentations of facial emotion and gender discrimination stimuli. The emotion discrimination condition consisted of the presentation of 12 happy faces and 12 disgust/fear faces. The gender discrimination condition consisted of the presentation of 12 male faces and 12 female faces. Condition-specific brain activations were compared between non-affected siblings and normal comparison subjects RESULTS : The facial information processing related brain regions including fusiform gyrus, several areas of frontal, temporal, occipital, and cerebellar regions exhibited more activation during gender discrimination than emotion discrimination tasks in each group. During gender discrimination task, siblings of schizophrenic patients showed less activation in right fusiform gyrus, both middle and superior frontal gyrus, left cuneus, and left inferior frontal gyrus, compared with normal comparison subjects. CONCLUSION : Dysfunctional facial information processing, such as a deficit in gender discrimination, might be an endophenotype of schizophrenia.

OBJECTIVES: Diffuse tensor imaging (DTI) was applied to explore the difference in regional distribution and extent of white matter (WM) abnormalities in boys with Attention-deficit/hyperactivity disorder (ADHD) versus boys with comorbid ADHD and tic disorders. METHODS: Fifteen boys with ADHD (mean age 9.3+/-1.8), 24 ADHD boys with chronic tic disorder or Tourette's disorder (9.9+/-1.2) and 9 age-, gender-matched controls (9.2+/-1.8) received DTI assessments. Fractional Anisotropy (FA) maps of WM were compared between groups with a voxel-wise analysis after intersubject registration to MNI space. RESULTS: Both groups, ADHD group and ADHD with tic disorder group, commonly showed decreased FA than healthy control group in left cerebellar middle peduncle and right frontal lobe, increased FA in right middle occipital WM. In the common areas of left cerebellar middle peduncle and right middle occipital WM, comorbid group showed broader areas of significant FA. The comorbid group also showed increased FA in right cerebellar peduncle, additionally. CONCLUSION: The findings in ADHD group support previous ADHD hypothesis of the functional abnormalities in corticocerebellar circuit, and suggest that ADHD might have more complicated pathology of neuronal circuit including occipital visual system. The comorbid group showed common areas of overlapping but more extensive abnormalities and also had additional WM abnormalities. ADHD with chronic tic disorders may represent a severe form of ADHD with additional regions of abnormal connectivity.
