Comparative StudyThe evaluation of emotional facial expressions in early postpartum depression mood: a difference between adult and baby faces?
Research suggests that depressive individuals exhibit disturbances in the evaluation of emotional facial expressions. Owing to the specific character of postnatal depressive mood, the purpose of the present study was to examine whether postpartum depressive mood intensity in the mothers would involve the same disturbances as depression or a specific distortion in the emotional evaluation of baby faces as compared to adult faces. ⋯ Our findings suggest that judgements of emotional facial expressions depend to a great extent on anxiety, which specifically increased negative perception of babies' emotions. Moreover, the only difference between mothers with and without postpartum depressive mood lays in their assessment of the babies' faces, neutral baby faces being judged to be less neutral, thus demonstrating the specificity of postpartum affective disorders.

Proposal of a socio-cognitive-behavioral structural equation model of internalized stigma in people with severe and persistent mental illness.
The social stigma of mental illness has received much attention in recent years and its effects on diverse variables such as psychiatric symptoms, social functioning, self-esteem, self-efficacy, quality of life, and social integration are well established. However, internalized stigma in people with severe and persistent mental illness has not received the same attention. ⋯ The main characteristics of the sample and the differences between groups with high and low internalized stigma were analyzed, a correlation analysis of the variables was performed, and a structural equation model, integrating variables of social, cognitive, and behavioral content, was proposed and tested. The results indicate the relationships among social stigma, discrimination experiences, recovery expectation, and internalized stigma and their role in the psychosocial and behavioral outcomes in schizophrenia spectrum disorders.

Prevalence, correlates, and comorbidities of adult ADHD symptoms in Korea: results of the Korean epidemiologic catchment area study.
We examined the prevalence, correlates, and comorbidities of adult attention-deficit hypersensitivity disorder (ADHD) symptoms in a Korean community using data from the National Epidemiological Survey of Psychiatric Disorders in Korea conducted in 2006. A total of 6081 subjects aged 18 to 59 years participated in this study. Diagnostic assessments were based on the Adult ADHD Self-Report Scale Screener and Composite International Diagnostic Interview administered by lay interviewers. ⋯ The 6 month prevalence of adult ADHD symptoms was 1.1%. Associations between ADHD symptoms and alcohol abuse/dependence, nicotine dependence, mood disorders, major depressive disorder, bipolar disorder, anxiety disorders, obsessive-compulsive disorder, post-traumatic stress disorder, social phobia, specific phobia, somatoform disorder, sleep disturbances, and suicidality were overwhelmingly positive and significant (P<0.05), after controlling for gender and age. Adult ADHD symptoms are highly associated with substance abuse, mood and anxiety disorders, somatoform disorders, sleep disturbances and suicidality, suggesting that clinicians should carefully evaluate and treat such psychiatric disorders in adults with ADHD symptoms.

Effects of the BDNF Val66Met polymorphism on neural responses to facial emotion.
The brain derived neurotrophic factor (BDNF) Val66Met polymorphism has been associated with affective disorders, but its role in emotion processing has not been fully established. Due to the clinically heterogeneous nature of these disorders, studying the effect of genetic variation in the BDNF gene on a common attribute such as fear processing may elucidate how the BDNF Val66Met polymorphism impacts brain function. Here we use functional magnetic resonance imaging examine the effect of the BDNF Val66Met genotype on neural activity for fear processing. ⋯ The results show that during fear processing, Met allele carriers show an increased neural response in regions previously implicated in mediating autonomic arousal. Further, the Met carriers show decreased functional connectivity with the hippocampus, which may reflect differential retrieval of emotional associations. Together, these effects show significant differences in the neural substrate for fear processing with genetic variation in BDNF.

Impairments of facial emotion recognition and theory of mind in methamphetamine abusers.
Chronic use of methamphetamine is related to behavioral disturbances including depression, aggressive behavior, and social isolation. These alterations of social behavior may be attributable to impairments in social cognition. However, few studies have evaluated social cognition in methamphetamine (MA) abusers. ⋯ In addition, impairments in cognitive flexibility are correlated with impairments in facial emotion recognition and ToM within MA abusers. These findings lend further support to the assertion that the capacity to identify emotions from facial expression and infer mental state of others is impaired in MA abusers. Therefore, treatment and rehabilitation for MA abusers must consider role of social cognition and include relearning social interactions and behaviors.
