Persistent negative symptoms (PNS) include both primary and secondary that persist after adequate treatment, represent an unmet therapeutic need. Published magnetic resonance imaging (MRI) evidence of structural resting-state functional brain abnormalities in schizophrenia with PNS has been inconsistent. Thus, the purpose this meta-analysis is to identify regions patients compared healthy controls.We systematically searched PubMed, Web Science, Embase for studies based on five research methods, including voxel-based morphometry (VBM), diffusion tensor (DTI), connectivity (FC), amplitude low-frequency fluctuation or fractional (ALFF/fALFF), regional homogeneity (ReHo). Afterward, we conducted a coordinate-based by using activation likelihood estimation algorithm.Twenty-five MRI thirty-two were included meta-analyses. Our analysis revealed presence alterations some bilateral insula, medial frontal gyrus, anterior cingulate left amygdala, superior temporal inferior gyrus middle as well differences precuneus, thalamus, lentiform nucleus, posterior gyrus.Our study suggests are consistently located prefrontal, temporal, limbic subcortical regions, concentrated thalamo-cortical circuits default mode network (DMN). This provides new insights targeted treatment intervention delay further progression symptoms.[https://www.crd.york.ac.uk/prospero/], identifier [CRD42022338669].

Psychotic symptoms are among the most debilitating and challenging presentations of severe psychiatric diseases, such as schizophrenia, schizoaffective, bipolar disorder. A pathophysiological understanding intrinsic brain activity underlying psychosis is crucial to improve diagnosis treatment. While a potential continuum along psychotic spectrum has been recently described in neuroimaging studies, especially for what concerns absolute relative amplitude low-frequency fluctuations (ALFF fALFF), these efforts have given heterogeneous results. transdiagnostic meta-analysis ALFF/fALFF patients with compared healthy controls currently lacking. Therefore, this pre-registered systematic review PubMed, Scopus, Embase were searched articles comparing between controls. quantitative synthesis differences (f)ALFF was performed Seed-based d Mapping, adjusting age, sex, duration illness, clinical severity. All results corrected multiple comparisons by Family-Wise Error rates. lower ALFF fALFF detected comparison controls, no specific finding survived correction comparisons. Lack might explain discordant findings highlighted previous literature. Other explanations include methodological issues, lack standardization pre-processing or analytical procedures studies. Future research on should prioritize replicability individual Systematic registration https://osf.io/ , identifier (ycqpz).

Background/Objectives: Violent behaviors are uncommon in patients with schizophrenia (Sch), but when present, exacerbate stigma and challenge treatment. The following study aimed to identify the structural abnormalities associated violent Sch by implementing a validated tool specifically designed evaluate psychiatric populations, as well performing region-of-interest neuroimaging analyses, focused on areas commonly neurobiology of violence aggression. Methods: Eighty-three participants were divided into three groups: (Sch+V, n = 34), without (Sch-V, 28), healthy controls (HC, 21). Structural analyses performed across groups assess gray matter volume (GMV) cortical thickness (CT) differences regions previously implicated aggressive behaviors. Results: data revealed significant reductions GMV right amygdala diminished bilateral dorsolateral prefrontal cortices (dlPFC) Sch+V compared Sch-V HCs. Right amygdalar also demonstrated negative correlational trend hostility scores Sch+V. Conclusions: These findings underscore disruptions integrity dlPFC—responsible for inhibitory control—and amygdala—central emotional processing Sch. Future research should aim investigate potential functional interactions at network level gain deeper understanding neurobiological underpinnings this population.

Very late-onset schizophrenia-like psychosis (VLOSLP) is a subtype of schizophrenia spectrum disorders in which individuals experience psychotic symptoms for the first time after age 60. The incidence VLOSLP shows linear relationship with increasing age. However, no studies have reported alterations spontaneous brain activity among patients and their correlation cognitive function clinical symptoms. To explore correlations using resting-state functional magnetic resonance imaging. This study included 33 34 healthy controls. assessment utilized Mini Mental State Examination, Montreal Cognitive Assessment, Repeatable Battery Assessment Neuropsychological Status (RBANS). Clinical characteristic acquisition was performed via Positive Negative Syndrome Scale (PANSS). All participants were scanned imaging, data processed amplitude low-frequency fluctuations (ALFF), fractional ALFF (fALFF), regional homogeneity, voxel-mirrored homotopic connectivity (VMHC). group presented decreased values left cuneus, right precuneus, precentral gyrus, paracentral lobule; increased fALFF caudate nucleus; calcarine fissure surrounding cortex (CAL) precuneus; homogeneity putamen; VMHC bilateral CAL, superior temporal cuneus. In group, precuneus negatively correlated Examination score PANSS positive subscale score, CAL RBANS total delayed memory score. changes are concentrated regions, may be associated impairment clinically

This study aims to explore the relationships between agitation behavior, cognitive function and cortical thickness in first-episode drug-naïve schizophrenia (FESN). A total of 55 male healthy controls (HC) 79 inpatients with FESN were enrolled present study. Whole brain was extracted from T1-weighted MRI using Freesurfer Version 7.4.1 software package. Cognitive evaluated MATRICS Consensus Battery (MCCB). The Positive Negative Syndrome Scale-Excited Component (PANSS-EC) is used divide these into group (FESN+A) non-agitation (FESN+NA). Correlation analysis employed investigate potential associations function. FESN+A had higher Scale (PANSS) score, positive symptom general psychopathology score than FESN+NA group. Both FESN+A/NA groups showed significantly worse performance HC symbol coding, working memory, attention/vigilance, reasoning problem solving, social cognition. performed on memory when comparing Furthermore, left paracalcarine gyrus increased group, compared HC. thicker right posterior cingulate cortex (rPCC) rPCC negatively correlated demonstrated that abnormal may be related behavior patients FESN+A, suggesting a treatment target for impairment schizophrenia.

Schizophrenia (SZ) is associated with the highest disability rate among serious mental disorders. Excited symptoms are core of SZ, which appear in early stage, followed by other stages disease subsequently. These destructive and more prone to violent attacks, posing a economic burden society. Abnormal spontaneous activity orbitofrontal cortex had been reported be excited patients SZ. However, whether abnormality appears first-episode drug-naïve SZ has still remained elusive.A total 56 27 healthy controls underwent resting-state functional magnetic resonance imaging (rs-fMRI) positive negative syndrome scale (PANSS). First, differences fractional amplitude low-frequency fluctuations (fALFF) between were examined identify cerebral regions exhibiting abnormal local activity. Based on fALFF results, connectivity analysis was performed determine changes Finally, correlation exciting analyzed.Compared controls, showed significant decrease intrinsic bilateral precentral gyrus, postcentral left cortex. In addition, significantly reduced values several regions, mainly distributed right middle frontal paracentral lobules, median cingulate. Further analyses that as well negatively correlated SZ.Our results indicated important role suggested may valuable predict occurrence symptoms. provide new direction explore

Suicide and homicide are considered important problems in public health. This study aims to identify the cognitive performance of suicidal homicidal behaviors people with schizophrenia spectrum disorders, as well examining whether there shared neuropsychological mechanisms. A systematic review recent literature was carried out from September 2012 June 2022 using Medline (via PubMed), Scopus, Embase, Cochrane databases. Among 870 studies initially identified, 23 were finally selected (15 related 8 behaviors). The results evidenced a relationship between impairment behavior; meanwhile, for behaviors, no consistent found. High seems act protective factor against violent behavior but not indeed, it can even risk behavior. To date, is insufficient evidence that neurocognitive mechanisms exist. However, processing speed visual memory seem be affected presence both behaviors.
