Summary: This study aimed to understand the use of clozapine and electroconvulsive therapy (ECT) in individuals with treatment-resistant psychosis. The study found that the utilization of these treatments was low and clozapine trials were often terminated prematurely without adequate testing. The study suggests strategies should be implemented to optimize the use of clozapine therapy and ECT in clinical settings to improve the therapeutic effectiveness for treatment-resistant psychosis.

Summary: This study investigates the relationship between minor physical anomalies (MPA) and treatment resistance in schizophrenia (TRS). It found that TRS patients had higher total MPA score, and MPAs in the eye and mouth regions were more frequent in TRS patients compared to non-TRS patients. The total MPA score was correlated to BPRS-E total and BPRS positive scores in TRS patients. These findings suggest that MPA might contribute to treatment resistance in schizophrenia.

Summary: Evidence suggests that the variable response to antipsychotic treatment in schizophrenia reflects distinct biological subtypes associated with changes in the immune system. Different subtypes of schizophrenia patients show varying alterations in inflammatory markers during treatment, with only the treatment-responsive group exhibiting a significant decrease in inflammatory markers post-treatment.Persistent inflammation may be a biological trait marker of treatment resistance in schizophrenia.

Summary: Autistic adults and those with schizophrenia demonstrate similar levels of reduced social cognitive performance at the group level, but a significant portion of both groups still exhibit normative performance. Nearly half of autistic participants performed in the normal range, while over a third of participants with schizophrenia also did, accompanied by a hostility bias not commonly found in autistic individuals. These findings challenge the assumption that difficulties in social cognition are a uniform characteristic of these clinical conditions in those without intellectual disability.

Summary: Inaccurate self-assessment is common among people with serious mental illness and it negatively affects their functional outcomes. This study used network modeling to explore the temporal relationships between confidence, accuracy judgments, and feedback. The results suggest that individuals with schizophrenia and bipolar disorder have stronger connections between confidence and accuracy judgments, but weaker associations between feedback and subsequent judgments compared to healthy controls.

Summary: This study examined the impact of childhood trauma on day-to-day social experiences among individuals with psychotic disorders or affective disorders. The results showed that higher levels of childhood trauma were associated with increased perceived threat, negative self-perception, reduced social motivation, desire for social avoidance, and lower sense of belongingness during recent social interactions. These negative social perceptions were primarily linked with emotional abuse and neglect. It was also found that paranoia was more strongly associated with negative social perceptions among individuals with high levels of trauma. However, childhood trauma was not associated with the frequency or type of social interactions.

Summary: Social determinants of health (SDoHs) have a significant impact on the health of individuals with schizophrenia-spectrum psychotic disorders (SSPDs), with risk factors including childhood abuse, parental psychopathology, parental communication problems, bullying, and low socioeconomic status in urban areas. Racial/ethnic discrimination and social fragmentation are also associated with the prevalence and symptoms of psychosis. Homeless populations and seriously mentally ill individuals are more likely to experience food insecurity. Further research is needed to understand the positive factors and develop interventions to reduce the adverse health impacts of SDoHs.

Summary: Cognitive impairment is strongly related to disability and educational attainment, and previous drug development efforts have focused on transmitter systems associated with specific conditions. However, recent genomics studies suggest common influences on cognition across populations and conditions. Stimulation of muscarinic cholinergic receptors (M1 and M4) shows potential for enhancing cognition and treating psychotic symptoms, especially with recent developments improving tolerability. The M1 and M4 receptor stimulation may serve as a trans-diagnostic treatment model.

Summary: This study examined the ethno-racial differences in daily functioning among individuals with serious mental illnesses, specifically focusing on non-Latinx White, non-Latinx Black, and Latinx participants. The findings indicate that Black participants engaged more in solitary or passive leisure activities compared to White and Latinx participants, and reported less vocational activity and home-based active leisure. While some of these differences were explained by socioeconomic status and symptom severity, further research is needed to explore sociocultural and racism-related factors. Clinical implications and suggestions for future research are discussed.

Summary: Exposure to stressful experiences is a significant risk factor for mental disorders, and pharmacological interventions targeting stress-induced alterations can help restore brain function. Lurasidone, an antipsychotic drug, has been shown to normalize the impairments caused by stress exposure and could be a valuable treatment for stress-induced mental illnesses. However, the mechanisms underlying the therapeutic effects of lurasidone are not well understood. This study found that chronic lurasidone treatment counteracted some of the transcriptional changes induced by chronic mild stress exposure, providing new insights into the potential therapeutic effects of lurasidone.

The research shows that ELIS affects how youth respond to social rewards, and similar impairments in social reward processing are observed in youth with depression. The authors propose a preliminary model that suggests neurobehavioral disruptions in social reward processing as a mediating factor in the connection between ELIS and depression.

Summary: Restricted and repetitive behaviors (RRBs) are characteristic features of neuropsychiatric disorders. This study focused on repetitive self-grooming behavior and investigated the involvement of the Pax2 gene in its control. Through the use of Pax2 neuron-specific deletion mice, the study found that the deletion of Pax2 gene affects the expression of the Arc gene in the prefrontal cortex, leading to impaired synaptic plasticity and excitatory/inhibitory imbalance, thereby contributing to the occurrence of repetitive self-grooming behavior.

Summary: Cognitive impairment is related to both white matter macrostructure and microstructure in bipolar disorder patients. However, there is inconsistency in the results of the studies examining this relationship. Some studies have found an association between higher fractional anisotropy in white matter and better complex attention skills and executive functioning in bipolar disorder patients, while others have found no associations. Further research with increased statistical power and standardized methods is needed.

Summary: This study provides a systematic review and meta-analysis on the effectiveness of repetitive transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) for post-traumatic brain injury (TBI) symptoms. The results show that non-invasive brain stimulation techniques have a small overall effect on TBI sequelae, with significant effects observed for anxiety and headache. However, larger randomized controlled trials with longer follow-ups, optimized stimulation parameters, and standardized methodology are needed to establish the efficacy of these techniques in addressing TBI sequelae.

Summary: There is substantial evidence that the development of the nervous system is related to the composition and functions of the gut microbiome. The communication between the central nervous system (CNS) and the gut microbiota is bidirectional, with various routes such as immune, endocrine, and neural circuits. Dysbiosis of the gut microbiota has been associated with neuropsychiatric diseases and psychological disorders. Fecal microbiota transplantation (FMT) therapy has shown a causal-effect relationship between the gut microbiota and behavioral features. Interventions based on prebiotics, probiotics, or synbiotics have demonstrated their influence on neurological disorders through the synthesis of neuroactive compounds and regulation of inflammatory and endocrine processes. Further research is needed to explore the impact of gut microbiota dysbiosis on psychiatric and psychological disorders and the potential therapeutic role of microbiota-based interventions.
