OBJECTIVE: The objective of this article is to identify best practices in the diagnosis and assessment of patients with schizophrenia spectrum and other psychotic disorders. The diagnosis and assessment may occur in a range of situations from the emergency room to the outpatient clinic and at different stages of the disorder. The focus may be on acute exacerbations of illness, residual symptoms, levels of function, or changes in the response to treatment. METHODS: A systematic search was conducted for guidelines published in the last 5 years for schizophrenia and schizophrenia spectrum disorders...

Although selective activation of the M1 muscarinic acetylcholine receptor (mAChR) subtype has been shown to improve cognitive function in animal models of neuropsychiatric disorders, recent evidence suggests that enhancing M4 mAChR function can also improve memory performance. Positive allosteric modulators (PAMs) targeting the M4 mAChR subtype have shown therapeutic potential for the treatment of multiple symptoms observed in schizophrenia, including positive and cognitive symptoms when assessed in acute preclinical dosing paradigms...

BACKGROUND: Higher lifetime antipsychotic exposure has been associated with poorer cognition in schizophrenia. The cognitive effects of adjunctive psychiatric medications and lifetime trends of antipsychotic use remain largely unclear. We aimed to study how lifetime and current benzodiazepine and antidepressant medications, lifetime trends of antipsychotic use and antipsychotic polypharmacy are associated with cognitive performance in midlife schizophrenia. METHODS: Sixty participants with DSM-IV schizophrenia from the Northern Finland Birth Cohort 1966 were examined at 43years of age with an extensive cognitive test battery...

Cariprazine is a new dopamine D2 and D3 receptor partial agonist antipsychotic. Meta-analytic evidence of efficacy in acute schizophrenia and specific groups of patients is lacking. We carried out a meta-analysis in patients with acute schizophrenia to evaluate the efficacy of cariprazine over placebo and active comparators in overall symptoms, positive and negative symptoms and quality of life. Low and high (≥6 mg/day) doses were tested separately. The possible effect of clinical-demographic modulators was also tested...

BACKGROUND AND OBJECTIVES: Although the use of oral risperidone in children and adolescents has been well studied, there is little information on the intramuscular use of long-acting injectable risperidone (LAIR). The aims of this study were to investigate the effectiveness and adverse effects of LAIR in children and adolescents with conduct disorder, bipolar disorder, and schizophrenia. METHODS: In total, 42 patients (age range 12-17 years) who were non-adherent to oral antipsychotic drugs, received 25 mg/day of LAIR intramuscularly every 2 weeks...

Ying Liang, Xin Yu
BACKGROUND: Effective management strategies for the negative symptoms of schizophrenia remain an unmet need, and data on the use of antipsychotics in this population are scarce, particularly in Chinese patients. Therefore, we investigated amisulpride for the treatment of Chinese patients with predominantly negative symptoms of schizophrenia. METHODS: This post hoc subanalysis of the prospective Effectiveness and Safety of Amisulpride in Chinese Patients with Schizophrenia (ESCAPE) study included adult Chinese patients with an International Classification of Diseases-10 diagnosis of schizophrenia and predominantly negative symptoms, who received amisulpride for 8 weeks...

OBJECTIVE: Overestimating patients' medication adherence diminishes the ability of psychiatric care providers to prescribe the most effective treatment and to identify the root causes of treatment resistance in schizophrenia. This study was conducted to determine how credible patient drug adherence information (PDAI) might change prescribers' treatment decisions. METHODS: In an online survey containing 8 clinical case vignettes describing patients with schizophrenia, health care practitioners who prescribe antipsychotics to patients with schizophrenia were instructed to choose a preferred treatment recommendation from a set of predefined pharmacologic and non-pharmacologic options...

Metabolic disturbance is a common side effect of olanzapine (OLZ); however, the relationships between plasma OLZ concentration (COLZ) and metabolic disturbance remain unclear. Our previous study revealed that COLZ≧22.77ng/mL was a positive predictor of therapeutic efficacy in patients with schizophrenia. This study aimed to investigate the roles of OLZ or N-desmethyl-olanzapine (DMO) in metabolic outcomes among OLZ-treated patients with schizophrenia. The metabolic syndrome (MS) was diagnosed based on the modified the National Cholesterol Education Program Adult Treatment Panel III criteria for Asians...

AIM: Second-generation antipsychotics are commonly used to treat schizophrenia, but may cause metabolic syndrome (MetS) in a subset of patients. The mechanisms of antipsychotic-related metabolic changes remain to be established, especially in first-episode psychosis (FEP) patients. METHODS: In the present study, we used a chip technology to measure metabolic (C-peptide, insulin, leptin, adiponectin and resistin) and inflammatory biomarkers (ferritin, interleukin-6, interleukin-1α, tumour necrosis factor-α and plasminogen activator inhibitor-1) in the serum samples of a population of FEP patients before and after 7 months of antipsychotic drug treatment, compared to control subjects (CS)...

BACKGROUND: While antipsychotic medications are the mainstay of therapy for individuals with schizophrenia and psychotic disorders, their use is associated with adverse effects on physical health that require the attention and care of prescribers. METHODS: We used the ADAPTE process to adapt existing guideline recommendations from the National Institute for Health and Care Excellence (NICE) and Scottish Intercollegiate Guidelines Network (SIGN) guidelines on the dosing of antipsychotics and antipsychotic polypharmacy, screening for adverse effects of antipsychotics, and management of metabolic and extrapyramidal side effects to the Canadian context...

Model systems of psychosis, such as schizotypy or sleep deprivation, are valuable in informing our understanding of the etiology of the disorder and aiding the development of new treatments. Schizophrenia patients, high schizotypes, and sleep-deprived subjects are known to share deficits in oculomotor biomarkers. Here, we aimed to further validate the schizotypy and sleep deprivation models and investigated, for the first time, their interactive effects on smooth pursuit eye movements (SPEM), prosaccades, antisaccades, predictive saccades, and measures of psychotomimetic states, anxiety, depression, and stress...

Efforts to develop psychosocial interventions that specifically target social cognition in schizophrenia spectrum disorders began nearly two decades ago. The field has matured considerably since then and has engendered a great deal of optimism about this treatment approach. Indeed, the efficacy of social cognitive interventions, especially those that address multiple domains of social cognition, has received substantial support. This article critically evaluates the current evidence for social cognitive interventions, identifies limitations and open questions, and suggests priorities and directions for further research...

BACKGROUND: Aripiprazole lauroxil (AL) is a long-acting injectable atypical antipsychotic recently approved for treatment of schizophrenia on the basis of a large-scale trial of two doses of AL versus placebo. There are no direct-comparison studies with paliperidone palmitate (PP; long-acting antipsychotic used most often in acute settings) for the acute psychotic episode. OBJECTIVES: To indirectly compare efficacy and safety of the pivotal AL study with all PP studies meeting indirect comparison criteria...

Sensory impairments constitute core dysfunctions in schizophrenia. In the auditory modality, impaired mismatch negativity (MMN) has been observed in chronic schizophrenia and may reflect N-methyl-d-aspartate (NMDA) hypo-function, consistent with models of schizophrenia based on oxidative stress. Moreover, a recent study demonstrated deficits in the N100 component of the auditory evoked potential (AEP) in early psychosis patients. Previous work has shown that add-on administration of the glutathione precursor N-acetyl-cysteine (NAC) improves the MMN and clinical symptoms in chronic schizophrenia...

RATIONALE: Psychotic disorders, such as schizophrenia, as well as some mood disorders, such as bipolar disorder, have been suggested to share common biological risk factors. One such factor is reelin, a large extracellular matrix glycoprotein that regulates neuronal migration during development as well as numerous activity-dependent processes in the adult brain. The current study sought to evaluate whether a history of stress exposure interacts with endogenous reelin levels to modify behavioural endophenotypes of relevance to psychotic and mood disorders...

Brain-derived neurotrophic factor (BDNF) is an important neurotrophin in the brain that modulates dopaminergic neurons. In this study, we aimed to investigate the changes in serum BDNF levels of children with attention-deficit/hyperactivity disorder (ADHD) in response to OROS methylphenidate treatment. We also aimed to determine whether there were any pre-post-differences between ADHD subtypes and comorbid psychiatric disorders in serum BDNF levels. Fifty male children with ADHD and 50 male healthy controls within the age range of 6-12 years were recruited to the study...

There is growing evidence that the cerebellum plays a crucial role in the pathophysiology of schizophrenia symptoms. Despite increasing evidence for cerebellar involvement in affective, attentive, and cognitive functions including language processing and perception, investigations of cerebellar contributions to auditory verbal hallucinations (AVH) in schizophrenia are lacking. Using structural magnetic resonance imaging at 3T, we investigated the data of 20 patients with schizophrenia and 14 matched healthy controls...

This study compared baseline characteristics of Black Americans and Caucasians with first-episode psychosis in the Recovery After an Initial Schizophrenia Episode Early Treatment Program (RAISE-ETP). Black American (N=152) and Caucasian (N=218) participants were compared on demographic, psychosocial, clinical, and neurocognitive measures. Results indicated several notable racial differences in baseline characteristics: a greater proportion of Black Americans than Caucasians were female, and Black Americans reported less personal and parental education than Caucasians...
