Schizophrenia is a chronic and devastating brain disorder with ongoing cognitive, behavioral, and emotional deteriorated functions. Neurofeedback training, which enables the individuals to regulate their brain activity using a real-time feedback loop, is increasingly investigated as a potential alternative intervention for schizophrenia. This study aimed to explore the effect of short but intensive neurofeedback training for schizophrenic patients with difficulty for long-time training. A middle-aged woman with chronic schizophrenia completed the intensive training of alpha/beta2 (20-30 Hz) in four consecutive days with a total training duration of 13...

Evidence suggests that activation of the tryptophan catabolite (TRYCAT) pathway is involved in the pathophysiology of schizophrenia. However, no previous study examined whether TRYCAT pathway activation is associated with deficit schizophrenia. We measured IgA responses to TRYCATs, namely quinolinic acid, picolinic acid, kynurenic acid, xanthurenic acid, and anthranilic acid and 3-OH-kynurenine, in 40 healthy controls and in schizophrenic patients with (n = 40) and without (n = 40) deficit, defined according to the Schedule for the Deficit Syndrome (SDS)...

Medication discontinuation is a major risk factor for relapse in schizophrenic patients. The present study investigated the rate and clinical correlates of complete medication discontinuation in the year after hospital discharge. Data collected from 236 schizophrenia patients who were prescribed anti-psychotics documented socio-demographic characteristics, symptom severity, insight, and attitudes towards medication in the week before their discharge and the experience of caregiver burden for their primary caregiver as recorded at the time of hospitalization...

In schizophrenia, processing of self-related stimuli has been shown to be altered. It is unclear whether altered self-processing in schizophrenia is confined to cognitive functions such as self-recognition, or whether it pertains to automatic lower-level perceptual processes. Visual face processing was tested in patients with schizophrenia (n=36) and healthy controls (n=33). Using a change detection paradigm (self, famous, unknown faces), we tested whether self-related stimuli gain access to awareness preferentially...

BACKGROUND: Schizophrenia is a chronic, relapsing, mental disorder, and lack of adherence is a common and severe problem in such patients leadingto global and heavy consequences for patients (relapses, hospitalizations, impaired quality of life…), for the family and for society. Improved understanding of the underlying reasons will help to form intervention strategies relevant to the context. OBJECTIVES: We aimed to assess medication adherence among stable patients suffering from schizophrenia and to identify factors associated with non-adherence...

INTRODUCTION: In schizophrenic disorders, supportive psychosocial therapies have been used as adjuncts to pharmacotherapy to help alleviate residual symptoms and to improve social functioning and quality of life. Among these therapies, psychoeducational therapies showed a significant efficacy on improving drug adherence and on reducing relapses. However, according to the French Health Agency, fewer than 10% of psychiatric structures in France offer registered psychoeducation programs...

OBJECTIVE: To investigate the interest in the attitudes toward antipsychotic medication in exploring medication non-adherence. METHODS: Schizophrenic patients (N=120) completed the Beliefs about Medicines Questionnaire and measures of medication adherence, and clinical outcomes. Comparison between four attitudinal groups and logistic regressions were performed. RESULTS: High level of adherence varied significantly between attitudinal groups (Accepting, 70%; Indifferent, 63%; Ambivalent, 50%; Sceptical, 14%; p<0...

This article attempts to identify and put into perspective the different approaches that could globally prevent the suffering induced by schizophrenia, from the detection of early psychosis to the impact on individual and family functioning and emotional health. Schizophrenia causes, at the community level, a number of difficult consequences and associated costs, which likely could be reduced if specific strategies, already known and documented internationally, were applied. Two areas not explored in this article: the role of medication and the issue of suicide prevention...

Impaired attentional processing of negative facial expressions is prominent in schizophrenia and has been shown to be associated with patients' social dysfunctions. However, little is known about when and which specific attention deficits influence social functions. Given the dynamic feature of attention, it is necessary to investigate the attention deficits in negative emotional processing unfolding in time. The current study used event-related potentials (ERPs) to investigate the temporal dynamics of attention deficits in emotion perception and their potential relationship with emotional/social impairments in neuroleptic naive schizophrenic patients...

Caregiver burden may be especially high in China. However, there has been no empirical study comparing burden experienced by caregivers who live with their patient kin and caregivers live separately from their kin. This study compared caregiver burden in cohabiting and non-cohabiting families and examined characteristics that may account for observed differences ion experienced burden. Patients were evaluated on symptoms, insight, attitudes toward medication before discharge and their prime caregivers were evaluated on family burden shortly after admission...

BACKGROUND: The difference of burden between caregivers of acute patients with schizophrenia and bipolar disorder has not been well studied in China, a culture where family responsibility has a very high value. Our aim is to compare family burden in these two categories diagnosis and to identify predictors of family burden in a large psychiatric hospital in China. METHODS: Two hundred forty-three schizophrenic patients and 200 bipolar patients were enrolled in a cross-sectional study...

INTRODUCTION: The progressive shifts in the legal and social contexts, along with major changes in information seeking habits with the development of the Internet, have placed patients' information at the core of medical practice. This has to be applied to the psychiatric fields as well, and to questions about how schizophrenic patients are being told their diagnosis nowadays in France. METHODS: This paper is a national and international literature review about schizophrenia diagnosis disclosure practices, from 1972 to 2014, using French and English languages and various psychology and medical databases...

BACKGROUND: Schizophrenia, in phenomenological psychopathology, is often described as a self disturbance and sometimes as a disturbance of the self-world relation. This study seeks to elaborate on these concepts by examining the significance of the Other in relation to these disturbances. METHOD: Levinas' account of the 'home' will be employed to interpret the phenomenon of 'positive withdrawal'. RESULTS: Positive withdrawal can be conceptualized as a means to domesticate the Other, and schizophrenia can be described as an alteration or absence of the normal mode of being at home in the world...

Antipsychotics are the drugs prescribed to treat psychotic disorders; however, patients often fail to adhere to their treatment, and this has a severe negative effect on prognosis in these kinds of illnesses. Among the wide range of risk factors for treatment nonadherence, this systematic review covers those that are most important from the point of view of clinicians and patients and proposes guidelines for addressing them. Analyzing 38 studies conducted in a total of 51,796 patients, including patients with schizophrenia spectrum disorders and bipolar disorder, we found that younger age, substance abuse, poor insight, cognitive impairments, low level of education, minority ethnicity, poor therapeutic alliance, experience of barriers to care, high intensity of delusional symptoms and suspiciousness, and low socioeconomic status are the main risk factors for medication nonadherence in both types of disorder...

Here we imaged serotonin 2A receptor (5-HT2AR) binding in a very rare population of monozygotic twins discordant for schizophrenia to provide insight into trait and state components in brain 5-HT2AR patterns. In four twin pairs not medicated with drugs that target 5-HT2AR, frontal 5-HT2AR binding was consistently lower (33%) in schizophrenic- relative to their healthy co-twins. Our results strongly imply low frontal 5-HT2AR availability as a state feature of schizophrenia. If replicated, ideally in a larger sample also including dizygotic twin pairs and drug-naïve patients, this finding critically advance our understanding of the complex pathophysiology of schizophrenia...

The aim of study was to investigate the effects of pyrroloquinoline quinone (PQQ) combined with d-serine on the modulation of glycine sites in the brain of rats using social recognition test. Rats were divided into seven groups (n=10) and given repeated intraperitoneal (ip) injections of saline, MK-801 (0.5mg/kg), clozapine (1mg/kg), haloperidol (0.1mg/kg), d-serine (0.8g/kg), PQQ (2.0μg/kg), or d-serine (0.4g/kg) combined with PQQ (1.0μg/kg) for seven days. A social recognition test, including assessment of time-dependent memory impairment, was performed...

The autonomic nervous system (ANS) dysfunction has been well described in schizophrenia (SZ), a severe mental disorder. Nevertheless, the coupling between the ANS and central brain activity has been not addressed until now in SZ. The interactions between the central nervous system (CNS) and ANS need to be considered as a feedback-feed-forward system that supports flexible and adaptive responses to specific demands. For the first time, to the best of our knowledge, this study investigates central-autonomic couplings (CAC) studying heart rate, blood pressure and electroencephalogram in paranoid schizophrenic patients, comparing them with age-gender-matched healthy subjects (CO)...

Suicide is a relatively common outcome along the course of bipolar disorder. Studies have shown a positive correlation between ideation or attempts of suicide and higher insight in schizophrenic patients. Nevertheless there are still few studies that evaluate the relationship between suicide and insight in mood disorders. Evaluate the relationship between insight and suicidal ideation or behavior in bipolar depression. A group of 165 bipolar patients were followed up along 1 year. Each patient's mood was assessed in every consultation according to DSM-IV-TR criteria...

BACKGROUND: The genetic influences in human brain structure and function and impaired functional connectivities are the hallmarks of the schizophrenic brain. To explore how common genetic variants affect the connectivities in schizophrenia, we applied genome-wide association studies assaying the abnormal neural connectivities in schizophrenia as quantitative traits. METHOD: We recruited 161 first-onset and treatment-naive patients with schizophrenia and 150 healthy controls...
