Psychotic experiences among police officers working in high-stress situations

Childhood trauma is a well-established risk factors for psychosis in adulthood (Kelleher et al., 2013). Recent work has suggested that this may be mediated by trauma exposure in adulthood, which frequently occurs among individuals exposed to childhood trauma and has likewise been linked to psychosis (Bhavsar et al., 2017). Nonetheless, trauma exposure in adulthood has been less studied in relation to psychosis, with some exceptions (e.g., crime victimization; Newbury et al., 2017; intimate partner violence: Shah et al., 2017).

ConclusionsSD are frequent in SZ subjects. Major depression, anticholinergic prescription and chronic low-grade peripheral inflammation may be the three targets of interest for addressing this specific issue.

Several lines of evidence support the hypothesis that abnormally elevated brain levels of kynurenic acid (KYNA), a metabolite of the kynurenine pathway (KP) of tryptophan degradation, play a pathophysiologically significant role in schizophrenia and other major neurodevelopmental disorders. Studies in experimental animal models suggest that KP impairments in these diseases may originate already in utero since prenatal administration of KYNA ’s bioprecursor, kynurenine, leads to biochemical and structural abnormalities as well as distinct cognitive impairments in adulthood. As KP metabolism during pregnancy is still i...

Authors: Luo Y, Zhang J, Wang C, Zhao X, Chang Q, Wang H, Wang C Abstract BACKGROUND: Schizophrenia affects approximately 10% of the world's population. Early detection of schizophrenia may significantly delay its progression. Although sensory gating deficits are reported in schizophrenia, it remains challenging how sensory gating deficits can be used with other metrics for risk detection and early diagnosis. RESEARCH DESIGN AND METHODS: Using EEG, the authors examined effects of sensory gating on the performance of 136 participants in a P50 sensory gating task, including patients with first-episode schizophrenia (...

By Emma Young Hikikomori is a dark term that describes people who stay holed up in their homes, or even just their bedrooms, isolated from everyone except their family, for many months or years. The phenomenon has captured the popular imagination with many articles appearing in the mainstream media in recent years, but, surprisingly, it isn’t well understood by psychologists.  The condition was first described in Japan, but cases have since been reported in countries as far apart as Oman, Indian, the US and Brazil. No one knows how many hikikomori exist (the term refers both to the condition and the people with ...

In this study, we compared facial emotion recognition performance in age- and gender-matched schizophrenia spectrum disorders subjects with (N = 52) and without (N = 52) a history of violence. Data on current symptom severity, Cluster B personality status, past victimization, and alcohol and substance misuse were also collected. Compared to those without, subjects with a history of violence showed worse facial emotion recognition performances, involving anger, fear, disgust, sadness, and happiness. When formally testing the reporting of angry faces, evidence of enhanced sensitivity to anger was ...

AbstractPharmacological inhibition of phosphodiesterase 10A (PDE10A) is being investigated as a treatment option in schizophrenia. PDE10A acts postsynaptically on striatal dopamine signaling by regulating neuronal excitability through its inhibition of cyclic adenosine monophosphate (cAMP), and we recently found it to be reduced in schizophrenia compared to controls. Here, this finding of reduced PDE10A in schizophrenia was followed up in the same sample to investigate the effect of reduced striatal PDE10A on the neural and behavioral function of striatal and downstream basal ganglia regions. A positron emission tomography...

AbstractStudies and findings regarding the impact of schizophrenia on quality of life (QOL) has been highly variable. This meta-analysis compared QOL between schizophrenia subjects and healthy controls with a focus on standardized measures. A systematic literature search was conducted through Pubmed, PsycINFO, EMBASE, Cochrane Library and Web of Science databases. Only studies using the World Health Organization Quality of Life (WHOQOL) or its brief version or the Short Form-36 Health Survey (SF-36) were included. Fifteen case-control studies with 2195 schizophrenia subjects and 1508 healthy controls were included in this ...
