Previous association studies have shown mixed results between glutamic acid decarboxylase like-1 (GADL1) gene polymorphism and prophylactic lithium response in bipolar disorder (BD) patients. In the present study, GADL1 gene expression was investigated in regard to lithium response, using Alda scale, in lymphoblastoid cells (LCLs) of 36 Caucasian BD patients. No difference in GADL1 expression was observed among LCLs from excellent-responders, non-responders or controls. Furthermore, lithium did not induce significant changes in GADL1 expression levels after 4 or 8 days...

Disruptive behavior disorders (DBDs), inclusive of oppositional defiant disorder (ODD) and conduct disorder (CD), are associated with outcomes likely to increase risk of mortality. Using Danish National Registers, a total of 1.92 million individuals including 9495 individuals with DBDs diagnosed by specialist services were followed from their first birthday to 2013. Those with and without DBDs were compared using mortality rate ratios (MRRs) estimated using Poisson regression and adjusted for calendar period, age, sex, family history of psychiatric disorders, maternal age at time of birth, paternal age at time of birth, parental education status, and parental employment status...

Child maltreatment (CM) worsens prognosis and quality of life in several psychiatric conditions. Meaning in life is a construct which relates to the sense of purpose that one can perceive in life, and is a key aspect of recovery in psychiatric patients. The lasting impact of CM on meaning in life and its mediating variables have not been studied in patients with chronic persistent psychiatric conditions. One hundred and sixty-six patients with bipolar disorder (N=35), psychotic disorder (N=73), anorexia nervosa (N=30) or borderline personality disorder (N=28) were assessed for meaning in life (revised version of the Life Regard Index (LRI-R)), for CM (Childhood Trauma Questionnaire (CTQ)) and for internalized/externalized psychopathology...

Cannabis use has been reported to affect the course of various psychiatric disorders, however its effect on the course of major depressive disorder (MDD) is not yet clear. We used data from Wave 1 and Wave 2 of the National Epidemiologic survey on Alcohol and Related Conditions (NESARC). Individuals with baseline MDD (N=2,348) were included in the study. Cannabis users without a Cannabis Use Disorder (CUDs) and individuals with a CUD were compared to nonusers using linear and logistic regression analyses controlling for sociodemographics, psychiatric disorders and substance use disorders at baseline...

The aim of this paper is to extensively review the current literature available on N-acetylcysteine (NAC) treatment for cocaine dependence (clinical and experimental studies). We screened all articles published before February 2016 reporting on the use of NAC as a pharmacological intervention for cocaine dependence or discussed its potential as a therapeutic approach for cocaine dependence. We described our results qualitatively. 21 studies matched our search criteria: 6 clinical trials and 15 animal studies...

Because human emotion varies greatly among individuals and is a qualitative factor, measuring it with any degree of accuracy is very difficult. Heart rate variability (HRV), which is used in evaluations of the autonomic nervous system (ANS), is used to evaluate human emotions. This study examines the validity of HRV as a tool to evaluate emotions using the International Affective Picture System (IAPS). For experimentation, five photos were selected for each of the categories of "happy," "unhappy", and "neutral" from among the images provided by the IAPS...

Recently, a lot of effort has been made to ground Rorschach interpretations to their evidence base. To date, however, no studies have yet described, via fMRI, what brain areas get involved when one takes the Rorschach. To fill this gap in the literature, we administered the ten-inkblot stimuli to 26 healthy volunteers during fMRI. Analysis of BOLD signals revealed that, compared to fixating a cross, looking at the Rorschach inkblots while thinking of what they might be associated with higher temporo-occipital and fronto-parietal activations, and with greater activity in some small, sub-cortical regions included in the limbic system...

: A significant correlation exists between violence and schizophrenia (SCZ). Recent studies matched some cognitive deficits like strong risk factors for violence with interesting applications in terms of treatment. Our objective was to conduct a systematic review of the effectiveness of cognitive remediation (CR) and social cognitive training (SCT) in the management of violent and aggressive behaviors in SCZ. METHODS: The electronic databases Pubmed, Web of Science, Cochrane Library and ScienceDirect were searched in, using combinations of terms relating to SCZ, CR and violence...

Previous behavioral studies have demonstrated an effect of eye gaze direction on the processing of emotional expressions in adults with social anxiety. However, specific brain responses to the interaction between gaze direction and facial expressions in social anxiety remain unclear. The present study aimed to explore the time course of such interaction using event-related potentials (ERPs) in participants with social anxiety. High socially anxious individuals and low socially anxious individuals were asked to identify the gender of angry or neutral faces with direct or averted gaze while their behavioral performance and electrophysiological data were monitored...

Obsessive-compulsive disorder (OCD) patients show increased insula activation to disgust-inducing images compared to healthy controls (HC). We explored whether this disgust reactivity was also present in the olfactory domain by conducting the first fMRI study of olfaction in OCD. Neural activation in response to pleasant and unpleasant odors (vs. unscented air) was investigated in 15 OCD and 15 HC participants using fMRI. OCD participants (vs. HC) had increased left anterior insula activation to unpleasant odors (vs...

The aim of this research was to assess implicit processing of social and non-social distracting cues in children with ADHD. Young people with ADHD and matched controls were asked to classify target words (LEFT/RIGHT) which were accompanied by a distracter eye-gaze or arrow. Typically developing participants showed evidence of interference effects from both eye-gaze and arrow distracters. In contrast, the ADHD group showed evidence of interference effects from arrow but failed to show interference from eye-gaze...

Impairment in daily functioning still represents a major treatment issue in schizophrenia and a more in-depth knowledge of underlying constructs is crucial for interventions to translate into better outcomes. This study aims to model factors influencing both functional capacity and real-life behaviour in a sample of outpatients with chronic schizophrenia, through a comprehensive assessment including evaluations of psychopathology, cognitive and social cognitive abilities, premorbid adjustment, family environment and early childhood experiences...

This paired case-control study aimed to compare characteristics between suicide attempters with high and low suicide intent in rural China. We evaluated 409 suicide attempters and their paired controls who were matched with the same gender, age (a difference of no more than 3 years), and similar residence. Compared to paired control, suicide attempt with high and low suicide intent shared the 3 common risk factors of negative life event, high depression score, and low social support score. In addition, mental disorder was an independent risk factor of suicide attempt with high intent...

Metacognition refers to a range of cognitive processes that allow one to form complex ideas of self and others and to use this information to navigate psychosocial challenges. Several studies in both early-phase and prolonged schizophrenia have demonstrated not only that significant deficits in metacognitive ability are present, but importantly that they are associated with significant functional impairment and decreased quality of life. In spite of the importance of metacognitive impairment in schizophrenia, relatively little is known about the biological substrates that may contribute to this dysfunction...

DNA methylation has been implicated in the pathogenesis of schizophrenia. EGR3 is considered as a potential candidate gene for schizophrenia. We conducted in vitro DNA methylation reaction, Lucia luciferase activity assay, and pyrosequencing assay to assess the DNA methylation of the EGR3 expression underlying the pathophysiology of schizophrenia. We found that DNA methylation of the putative EGR3 regulatory regions attenuated Lucia luciferase activity. There was no difference in the DNA methylation pattern of EGR3 between in 50 schizophrenic patients and 47 controls...

BACKROUND: The aim of the study was to investigate dynamic thiol/disulfide (SH/SS) homeostasis in untreated schizophrenia. METHODS: Blood thiol/disulfide homeostasis status, which reflects native thiol-disulfide exchanges, was investigated in 87 untreated patients (52 males, 35 females), and the obtained results were compared with 86 healthy controls. Blood serum native thiol and total thiol (ToSH) concentrations were measured in a paired test. The half value of the difference between native thiol and ToSH concentrations was calculated as the disulfide bond amount...

Although a few papers documented benefits of group therapeutic activities for individuals with dementia, there is a dearth of studies that have investigated the effects of group activities on persons with dementia. This paper introduces a theoretical framework of studying group therapeutic recreational activity, the Comprehensive Process Model of Group Engagement, and an assessment tool, the Group Observational Measurement of Engagement (GOME). We also report the psychometric properties of this assessment. One hundred and four persons with dementia took part in ten different group activities, with each activity conducted twice at random order so that 20 activities were observed for each group of participants...

BACKGROUND: Patients suffering from major depressive disorders (MDD) report anhedonia, low concentration and lack of goal-oriented behavior. Data from imaging and quantitative EEG (QEEG) studies show an asymmetry in the prefrontal cortex (PFC), with lower left as compared to right PFC-activity, associated with specific depression-related behavior. Cordance is a QEEG measurement, which combines absolute and relative power of EEG-spectra with strong correlations with regional perfusion...

A relation between different types of parental care, trauma in childhood and psychotic symptoms in adulthood has been proposed. The nature of this association is not clear and if it is more related to psychotic disorders per se or to a cluster of symptoms such as positive psychotic symptoms remains undefined. We have analysed the presence of childhood trauma using the CTQ scale and types of parental care using the PBI scale in three groups of subjects: borderline personality disorder patients (n=36), first psychotic episode patients (n=61) and healthy controls (n=173)...
