Alterations of the normal redox state can be found in all stages of schizophrenia, suggesting a key role for oxidative stress in the etiology and maintenance of the disease. Pharmacological blockade of N-methyl-D-aspartic acid (NMDA) receptors can disrupt natural antioxidant defense systems and induce schizophrenia-like behaviors in animals and healthy human subjects. Perinatal administration of the NMDA receptor (NMDAR) antagonist ketamine produces persistent behavioral deficits in adult mice which mimic a range of positive, negative, and cognitive symptoms that characterize schizophrenia...

Bright light can affect mood states and social behaviours. Here, we tested potential interacting effects of light and dopamine on facial emotion recognition. Participants were 32 women with subsyndromal seasonal affective disorder tested in either a bright (3000 lux) or dim light (10 lux) environment. Each participant completed two test days, one following the ingestion of a phenylalanine/tyrosine-deficient mixture and one with a nutritionally balanced control mixture, both administered double blind in a randomised order...

AIMS: To evaluate the usefulness of comprehensive nursing assessment as a strategy for determining the risk of delirium in older in-patients from a model of care needs based on variables easily measured by nurses. BACKGROUND: There are many scales of assessment and prediction of risk of delirium, but they are little known and infrequently used by professionals. Recognition of delirium by doctors and nurses continues to be limited. DESIGN AND METHODS: A case-control study...

BACKGROUND: Current neuroimaging perspectives on a variety of mental disorders emphasize dysfunction of the amygdala. The neuropeptide oxytocin (OXT), a key mediator in the regulation of social cognition and behavior, accumulates in cerebrospinal fluid after intranasal administration in macaques and humans and modulates amygdala reactivity in both species. However, the translation of neuromodulatory OXT effects to novel treatment approaches is hampered by the absence of studies defining the most effective dose and dose-response latency for targeting the amygdala...

Attention Deficit Hyperactivity Disorder (ADHD) is associated with social cognition impairment, executive dysfunction and motor abnormalities, consisting in the persistence of neurological soft signs (NSS). Theory of mind (ToM) and emotion recognition (ER) deficit of children with ADHD have been interpreted as a consequence of their executive dysfunction, particularly inhibitory control deficit. To our knowledge, there are not studies that evaluate the possible correlation between the ToM and ER deficit and NSS in the population with ADHD, while this association has been studied in other psychiatric disorders, such as schizophrenia...

This study of 8-16-year-olds was designed to test the hypothesis that reading comprehension impairments are part of the social communication phenotype for many higher-functioning students with autism spectrum disorder (HFASD). Students with HFASD (n = 81) were compared to those with high attention-deficit/hyperactivity disorder symptomatology (ADHD; n = 39), or typical development (TD; n = 44), on a comprehensive battery of oral language, word recognition, and reading comprehension measures. Results indicated that students with HFASD performed significantly lower on the majority of the reading and language tasks as compared to TD and ADHD groups...

OBJECTIVE: Mental health is becoming an increasingly important topic in healthcare. Psychiatric symptoms, which consist of subjective descriptions of the patient's experience, as well as the nature and severity of mental disorders, are critical to support the phenotypic classification for personalized prevention, diagnosis, and intervention of mental disorders. However, few automated approaches have been proposed to extract psychiatric symptoms from clinical text, mainly due to (a) the lack of annotated corpora, which are time-consuming and costly to build, and (b) the inherent linguistic difficulties that symptoms present as they are not well-defined clinical concepts like diseases...

The expression of cathepsin S (CatS), a microglia-specific lysosomal cysteine protease in the brain, is regulated by the intrinsic microglial circadian clock. We herein report that the diurnal variation of evoked synaptic responses of cortical neurons disappeared in cathepsin S-deficient (CatS(-/-)) mice. The dendritic spine density of the cortical neurons was significantly reduced by incubation with a recombinant CatS. Furthermore, CatS(-/-) mice exhibited impaired social interaction and social novelty recognition in the three-chamber test...

The emergence of providing care to diseased conspecifics must have been a turning point during the evolution of hominin sociality. On a population level, care may have minimized the costs of socially transmitted diseases at a time of increasing social complexity, although individual care-givers probably incurred increased transmission risks. We propose that care-giving likely originated within kin networks, where the costs may have been balanced by fitness increases obtained through caring for ill kin. We test a novel hypothesis of hominin cognitive evolution in which disease may have selected for the cognitive ability to recognize when a conspecific is infected...

Entertainment persuasion theory was applied to investigate how an epilogue to a dramatic episode with an educational subtext about bipolar disorder affected viewer processing and response. In an experiment, viewers (N = 89) were randomly assigned to watch the episode either with or without an epilogue. Exposure to the epilogue increased recognition of the subtext. It also increased counterarguing against the subtext, but only among viewers less involved with the episode's story. The epilogue decreased social distance for people with bipolar disorder and decreased their belief that bipolar disorder is not treatable...

OBJECTIVE: Understanding social and environmental factors that contribute to parental help-seeking intentions is an important step in addressing service underutilization for children in need of treatment. This study examined factors that contribute to parents' intentions to seek formal and informal help for child psychopathology (anxiety and attention-deficit/hyperactivity disorder [ADHD]). METHOD: A total of 251 parents (N = 128 mothers, N = 123 fathers; 49% Black, 51% White) read 3 vignettes describing children with anxiety, ADHD, and no diagnosis...

The specialized ability to learn and recall individuals based on distinct facial features is known in only a few, large-brained social taxa. Social paper wasps in the genus Polistes are the only insects known to possess this form of cognitive specialization. We analyzed genome-wide brain gene expression during facial and pattern training for two species of paper wasps (P. fuscatus, which has face recognition, and P. metricus, which does not) using RNA sequencing. We identified 237 transcripts associated with face specialization in P...

Addiction is a serious health problem which leads to general social impairment. The period of adolescence plays a significant role in drug abuse liability. Psychostimulants, such as modafinil (MOD), are majorly used by teenagers seeking improvements in cognition, which contributes to its indiscriminate use. The present study aimed to investigate the influence of MOD (64 mg/kg by gavage, once a day) treatment during adolescence (PND 28-42) on amphetamine (AMPH, 4 mg/kg i.p.) conditioned place preference (CPP) in early adulthood (PND 60)...

Mimicry of others' postures and behaviours forms an implicit yet indispensable component of social interactions. However, whereas numerous behavioural studies have investigated the occurrence of mimicry and its social sensitivity, the underlying neurocognitive mechanisms remain elusive. In this study, single pulse transcranial magnetic stimulation was used to measure corticospinal facilitation during a naturalistic behaviour observation task adapted from the behavioural mimicry literature. Motor evoked potentials (MEPs) in participants' right hands were measured as they observed stimulus videos of a confederate describing photographs...

The processing of social stimuli, such as human faces, is impaired in individuals with autism spectrum disorder (ASD), which could be accounted for by their lack of social motivation. The current study examined how the attentional processing of faces in children with ASD could be modulated by the learning of face-reward associations. Sixteen high-functioning children with ASD and 20 age- and ability-matched typically developing peers participated in the experiments. All children started with a reward learning task, in which the children were presented with three female faces that were attributed with positive, negative, and neutral values, and were required to remember the faces and their associated values...

INTRODUCTION: Physicians regularly encounter victims of violence. Although some at-risk groups are increasingly recognized as such, the risks faced by prisoners and detainees are often overlooked. The scope of violence against them is unknown and their treatment is often hampered by unique social and institutional impediments. This article reviews the need for improved recognition and protection of such patients and the associated obstacles, while presenting information on the experience, knowledge and attitudes of physicians in Israel regarding the maltreatment of prisoners and detainees...

The situation of missing children is one of the most emotional social issues worldwide. The search for and identification of missing children is often hampered, among others, by the fact that the facial morphology of long-term missing children changes as they grow. Nowadays, the wide coverage by surveillance systems potentially provides image material for comparisons with images of missing children that may facilitate identification. The aim of study was to identify whether facial features are stable in time and can be utilized for facial recognition by comparing facial images of children at different ages as well as to test the possible use of moles in recognition...

The impact of borderline personality pathology on facial emotion recognition has been in dispute; with impaired, comparable, and enhanced accuracy found in high borderline personality groups. Discrepancies are likely driven by variations in facial emotion recognition tasks across studies (stimuli type/intensity) and heterogeneity in borderline personality pathology. This study evaluates facial emotion recognition for neutral and negative emotions (fear/sadness/disgust/anger) presented at varying intensities...
