This article aimed to describe typical event-related potentials (ERP) components of emotional processing in patients with anxiety disorder and highly anxious individuals. ERP components associated with emotional processing could be broadly divided into three components with short, middle and long, respectively. Many studies show that patients with anxiety disorders are characterized by different emotional bias to specific stimuli and more sensitive to emotional stimuli than normal individuals. In addition, these emotional biases were stronger and quicker in patients with anxiety disorder than normal individuals. Some studies reported that anxious people show abnormality at the initial stage (e.g. P1) of emotional processing. However, other studies reported the abnormality at the late stage (e.g. LPP) or wholeness of emotional processing in anxious individuals. We summarized the updated finding of possible ERP components of emotional processing in patients with anxiety disorder and highly anxious individuals. The significance and clinical implication were discussed.

It is well-known that more than 50% of attention-deficit hyperactivity disorder (ADHD) cases also have comorbid psychiatric disorders. We evaluated the comorbid psychopathology of Korean children and adolescents with ADHD using a standardized diagnostic instrument. The Korean Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL-K) was administered and completed in 105 patients who had been referred to the outpatient and inpatient clinics at the Samsung Medical Center from March 2004 to May 2005. All of the cases were diagnosed as ADHD according to DSM-IV criteria. We analyzed their clinical characteristics and psychiatric comorbidities, and assessed the correlation of any comorbidity with gender, age and ADHD subtype. Among our 105 participants, 70 (66.7%) subjects were diagnosed with combined-type ADHD, 22 (21.0%) were the predominantly inattentive type, only 1 (1.0%) was determined to have the predominantly hyperactive-impulsive type of ADHD, and 12 (11.4%) were classified as not otherwise specified (NOS) ADHD. Eighty (76.2%) subjects had at least one comorbid disorder such as oppositional defiant disorder (n = 53, 50.5%), anxiety disorders (n = 35, 33.3%) and affective disorders (n = 15, 14.3%). Our patients ranged in age from five to 16 years. Among the factors including gender, age, and ADHD subtype, ADHD subtype was the only one significant to comorbidity in our study. The results of this study suggest that psychiatric comorbidity in Korean children with ADHD is similar to the results of previous studies in western countries. Out of all the ADHD subtypes, the combined-type group had a significantly higher ratio of comorbid disorders and psychopathologies.

OBJECTIVE: To investigate the prevalence of sleep disorders and the relevant determinants in a cohort of primary Sjögren' s syndrome (pSS) patients. METHODS: One hundred and eighty-six pSS patients were included in the study, who were admitted to Peking University People' s Hospital and met the criteria of inclusion and exclusion. Sleep quality was assessed using the Pittsburgh sleep quality index(PSQI).Depression, anxiety were evaluated by patient health questionnaire (PHQ)-9, generalized anxiety disorder(GAD)-7, respectively. The demographic and clinical data were also recorded.Disease activity and damage were evaluated with the European League Against Rheumatism Sjögren's syndrome disease activity index (ESSDAI). According to the PSQI score>7, the pSS patients were divided into 152 cases of sleep disorder group and 34 cases of normal sleep group. Mann-Whitney U test, Chi-square test or Fisher' s exact test, independent samples t test, Spearman correlation analysis and Logistic regression were used for statistical analysis. RESULTS: The prevalence of sleep disturbance (PSQI > 7) was 81.7% (152 / 186) in the pSS patients, and 52.7% (98/186) had moderate or severe sleep disorders (PSQI≥ 11). The mean PSQI score of sleep disordered group was (12.29±3.30), while the normal sleep group PSQI score was (5.50±1.20). The PSQI score, PHQ-9 score and GAD-7 score in the sleep-disordered group were significantly higher than those in the normal sleep group (P=0.000, 0.035, 0.031). The PSQI score in the sleep disordered group were significantly higher than those in the normal sleep group in seven aspects: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disorders, hypnotic drug use and daytime dysfunction. All of them had statistical significance. According to the results of Spearman correlation analysis, PSQI had significantly positive correlation with course of disease, anxiety, depression score (r=0.151, 0.240, 0.421, P < 0.05), but negatively correlated with C3, C4 (r=-0.021, -0.235, P < 0.05). Logistic analysis identified the course of disease(OR=2.809, 95%CI: 1.21-6.52)and PHQ-9 score(OR=1.422, 95%CI: 1.04-1.94)as predictors of sleep disorders. CONCLUSION The incidence of sleep disorder in the pSS patients was higher, which was closely related to the course of disease, anxiety, depression and other factors. It is critical to assess and manage comprehensively the disease.

Adolescents are in a transition period from children to adults, during which they are prone to a variety of emotional disorders, with anxiety and depression being the most common disorders. Anxiety and depressive symptoms are highly correlated and the comorbidity of anxiety and depression is common. At the same time, the most prominent behavioral changes in adolescence are the emergence of getting up late and sleeping late, and the circadian rhythm begins to delay. Previous studies have shown that circadian rhythm is closely related to anxiety and depression, but the association between circadian rhythm disorder and comorbidity of anxiety and depression remains unclear. This article reviews the prevalence, association and potential biological mechanism of circadian rhythm disorder and comorbidity of anxiety and depression in adolescents, so as to provide a possible reference for the prevention and control of comorbidity of anxiety and depression in adolescents.

OBJECTIVETo investigate the anxiety disorders and influence factors that occur in adolescent patients with cleft lip and palate and to provide theoretical foundation for mental intervention.

METHODSA total of 120 adolescent patients with cleft lip and palate were investigated using a general information questionnaire, the self-rating anxiety scale, and the social support rating scale (SSRS). The influence factors of anxiety disorders were analyzed.

RESULTSThe effective questionnaires were 119. The occurrence rate of anxiety disorder in adolescent patients was 49.6% (59/119), and the occurrence rates of mild, moderate, and severe anxieties were 41.2% (49/119), 7.6% (9/119), and 0.8% (1/119), respectively. The gender, residential area, disease category, family status (one child or no children), and incidence rate of anxiety disorder in patients were statistically different (P<0.05). The SSRS scores of patients with anxiety disorder were lower than those of patients without anxiety disorder (P<0.05). Multiple regression analysis showed that gender and social support were predictive factors of the occurrence of anxiety disorder (R=0.318).

CONCLUSIONA high anxiety disorder rate occurred in adolescent patients with cleft lip and palate. dender and social support were important influencing factors for anxiety disorder. In the after-mental intervention, considerable attention should be given to the anxiety disorders of patients and improve their mental health.

OBJECTIVES: Patients with schizophrenia often present idea of reference in social situations, but there has been a limitation in quantitatively measuring their reactions to the social stimuli. The aim of this study was to investigate behavioral characteristics of patients with schizophrenia in social situations in which idea of reference can be provoked. METHODS: Forty subjects with schizophrenia (21 males) and 26 healthy volunteers (17 males) performed the idea-of-reference-provoking task, which was composed of movie clips with scenes of two women sitting on a bench of 1 or 5 m away. The conditions consisted of "referential conversation", "non-referential conversation" or "no conversation". The reactions of the participants were rated by the questionnaires for self-referential perception, malevolent interpretation and anxiety reaction. RESULTS: There were significant group differences in the reactions on self-referential perception, malevolent interpretation and anxiety reaction. After the treatment, patients with schizophrenia showed improved scores of the reactions. In particular, score changes of malevolent interpretation and anxiety reaction in patients with schizophrenia were correlated with change of paranoia scale (rs=0.65, p<0.05 and rs =0.73, p<0.05, respectively). CONCLUSION: Patients with schizophrenia revealed self-referential bias and paranoid responses to social situations, which were improved after psychiatric treatment. Self-referential perceptions and paranoid responses may be state dependent rather than trait of schizophrenia.

Psychophysiological and functional neuroimaging studies have frequently and consistently shown that emotional information can be processed outside of the conscious awareness. Non-conscious processing comprises automatic, uncontrolled, and fast processing that occurs without subjective awareness. However, how such non-conscious emotional processing occurs in patients with various psychiatric disorders requires further examination. In this article, we reviewed and discussed previous studies on the non-conscious emotional processing in patients diagnosed with anxiety disorder, schizophrenia, bipolar disorder, and depression, to further understand how non-conscious emotional processing varies across these psychiatric disorders. Although the symptom profile of each disorder does not often overlap with one another, these patients commonly show abnormal emotional processing based on the pathology of their mood and cognitive function. This indicates that the observed abnormalities of emotional processing in certain social interactions may derive from a biased mood or cognition process that precedes consciously controlled and voluntary processes. Since preconscious forms of emotional processing appear to have a major effect on behaviour and cognition in patients with these disorders, further investigation is required to understand these processes and their impact on patient pathology.
