Over 50 million people around the world suffer from schizophrenia, a severe mental illness characterized by misinterpretation of reality. Although the exact causes of schizophrenia are still unknown, studies have indicated that inflammation and oxidative stress may play an important role in the etiology of the disease. Pro-inflammatory cytokines are crucial for normal central nervous development and proper functioning of neural networks and neurotransmitters. Patients with schizophrenia tend to have abnormal immune activation resulting in elevated pro-inflammatory cytokine levels, ultimately leading to functional brain impairments...

BACKGROUND: Schizophrenia and bipolar disorders are chronic illnesses that commonly present with symptoms of acute agitation and aggression. These symptoms must be managed rapidly to prevent potential harm to the patient and others, including their caregivers, peers, and health care workers. A number of treatment options are available to clinicians to manage acute agitation and aggression, including non-pharmacologic behavioral and environmental de-escalation strategies, as well as biological treatment options such as pharmacologic agents and electroconvulsive therapy...

Phosphodiesterases are important enzymes regulating signal transduction mediated by second messenger molecules cAMP or cGMP. PDE10A is a unique member in the PDE family because of its selective expression in medium spiny neurons. It is recognized as anti-psychotic drug target. Based on the structural similarity between our previous chemistry work on 8-aminoimidazo[1,2-a]pyrazines and the PDE10A inhibitors reported by Bartolome-Nebreda et al., we initialized a project for developing PDE10A inhibitors. After several rounds of optimization, we were able to obtain a few compounds with good PDE10A enzymatic activity...

Thioridazine (TDZ), originally an anti-psychotic drug, suppresses several types of cancer and has specificity for leukemia stem cells. The present study was performed to assess its effect on lung cancer stem-like cells, as its effect remains unknown. TDZ was utilized to treat lung cancer stem-like cells (A549 sphere cells) and its cytotoxic effect and mechanism were evaluated in vitro and in vivo. TDZ elicited cytotoxicity in A549 sphere cells and inhibited their proliferation in a dose-dependent pattern. A549 sphere cells treated with TDZ showed nuclear fragmentation, increased G0/G1 phase distribution, positive Annexin V staining, and a change in the expression of caspase family and cell cycle-associated proteins...

Clozapine is the most effective anti-psychotic medication for treatment refractory schizophrenia. A growing number of case reports have linked infection to high clozapine levels and associated adverse outcomes. We present a systematic review of published cases to clarify the relationship between infection and elevated clozapine levels. The case reports were located through PubMed and Embase. In addition, 8 new cases from two Australian states were included. Demographics, psychiatric diagnoses and medical morbidities, medications, clinical symptoms, clozapine levels, inflammatory markers and final clinical outcome were extracted...

Schizophrenia is a serious mental disease with a high mortality rate and severe social consequences. Due to insufficient knowledge about its etiopathogenesis, curative treatments are not available. One of the most promising new research concepts is the mild encephalitis hypothesis of schizophrenia, developed mainly by Karl Bechter and Norbert Müller. According to this hypothesis, a significant subgroup of schizophrenia patients suffer from a mild, but chronic, form of encephalitis with markedly different etiologies ranging from viral infections, traumas to autoimmune diseases...

Although our understanding of psychotic disorders has advanced substantially in the past few decades, very little has changed in the standard of care for these illnesses since the development of atypical anti-psychotics in the 1990s. Here, we integrate new insights into the pathophysiology with the increasing interest in early detection and prevention. First, we explore the role of N-methyl-d-aspartate receptors in a subpopulation of cortical parvalbumin-containing interneurons (PVIs). Postmortem and preclinical data has implicated these neurons in the positive and negative symptoms, as well as the cognitive dysfunction present in schizophrenia...

BACKGROUND: The relationship between young adulthood, women and psychosis was the focus for this systematic review. Age and gender are factors that can influence responses to illness. Research indicates that there are differences in how young men and women are affected biologically and psychosocially, including the presentation of a constellation of symptoms, response to anti-psychotic medications and how they assess their life circumstances. Yet in literature that examines experiences of young people with psychosis, the specific needs of young women are usually not presented separately...

Anti-NMDAR (N-methyl-D-aspartic acid receptor) encephalitis, first described in 2007, is a rare, autoimmune limbic encephalitis. In half of the cases anti-NMDAR antibodies are paraneoplastic manifestations of an underlying tumor (mostly ovarian teratoma). In the early stage of the disease psychiatric symptoms are prominent, therefore 60-70% of the patients are first treated in a psychiatric department. In most of the cases, typical neurological symptoms appear later. Besides the clinical picture and typical symptoms, verifying presence of IgG antibodies in the serum or CSF is necessary to set up the diagnosis...
