Published: April 4, 2024

Abstract Background This meta-analysis aimed to explore the most robust findings across numerous existing resting-state functional imaging and voxel-based morphometry (VBM) studies on structural brain alterations in individuals with autism spectrum disorder (ASD). Methods A whole-brain voxel-wise was conducted compare differences intrinsic activity gray matter volume (GMV) between ASD typically developing (TDs) using Seed-based d Mapping software. Results total of 23 (786 ASD, 710 TDs) 52 VBM (1728 1747 were included. Compared TDs, displayed decreases left insula (extending superior temporal gyrus [STG]), bilateral anterior cingulate cortex/medial prefrontal cortex (ACC/mPFC), angular right inferior gyrus, as well increases supplementary motor area precuneus. For meta-analysis, decreased GMV ACC/mPFC cerebellum, increased middle STG), olfactory cortex, precentral gyrus. Further, after overlapping differences. Conclusions The present multimodal demonstrated that exhibited similar both function structure ACC/mPFC, or default mode network (DMN), primary sensory regions. These contribute further understanding pathophysiology ASD.

Gut proinflammatory bacteria is associated with abnormal functional connectivity of hippocampus in unmedicated patients with major depressive disorder

Translational Psychiatry, Journal Year: 2024, Volume and Issue: 14(1)

Published: July 16, 2024

Abstract Accumulating evidence has revealed the gut bacteria dysbiosis and brain hippocampal functional structural alterations in major depressive disorder (MDD). However, potential relationship between microbiota function patients with MDD is still very limited. Data of resting-state magnetic resonance imaging were acquired from 44 unmedicated 42 demographically matched healthy controls (HCs). Severn pairs hippocampus subregions (the bilateral cornu ammonis [CA1-CA3], dentate gyrus (DG), entorhinal cortex, hippocampal–amygdaloid transition area, subiculum) selected as seeds connectivity (FC) analysis. Additionally, fecal samples participants collected 16S rDNA amplicon sequencing was used to identify altered relative abundance microbiota. Then, association analysis conducted investigate relationships abnormal FC microbiome features. Also, subregion values levels features separately or together support vector machine models distinguishing HCs. Compared HCs, exhibited increased left (CA2, CA3 DG) right (CA2 CA3), decreased posterior cingulate cortex. In addition, we found that level proinflammatory (i.e., Enterobacteriaceae ) significantly increased, whereas short-chain fatty acids producing-bacteria Prevotellaceae, Agathobacter Clostridium patients. Furthermore, CA3- CA3) positively correlated MDD. Moreover, patterns considered combination, best discrimination obtained (AUC = 0.92). These findings may provide insights into role underlying neuropathology

Effect of scanning duration and sample size on reliability in resting state fMRI dynamic causal modeling analysis

NeuroImage, Journal Year: 2024, Volume and Issue: 292, P. 120604 - 120604

Published: April 1, 2024

Despite its widespread use, resting-state functional magnetic resonance imaging (rsfMRI) has been criticized for low test-retest reliability. To improve reliability, researchers have recommended using extended scanning durations, increased sample size, and advanced brain connectivity techniques. However, longer runs larger sizes may come with practical challenges burdens, especially in rare populations. Here we tested if an technique, dynamic causal modeling (DCM), can reliability of fMRI effective (EC) metrics to acceptable levels without extremely long run durations or large samples. Specifically, employed DCM EC analysis on rsfMRI data from the Human Connectome Project. avoid bias, assessed four distinct DCMs gradually a randomized manner across ten permutations. We pseudo true positive false rates assess efficacy shorter (3.6, 7.2, 10.8, 14.4 minutes) replicating outcomes longest duration (28.8 min) when size was fixed at largest (n=160 subjects). Similarly, smaller (n=10, 20, …, 150 subjects) min). Our results revealed that rate below 0.05 all analyses. After reached 10.8 minutes, which yielded 92%, further extensions time showed no improvements rate. Expanding led enhanced outcomes, plateau n=70 subjects targeted top one-half ECs reference sample, regardless whether viable (10.8 employed. Encouragingly, exhibited approximately 80% n=20, 90% n=40 subjects. These suggest be option attain reliable times are not feasible.

Adverse childhood experiences and post-traumatic stress impacts on brain connectivity and alcohol use in adolescence

Child Neuropsychology, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 21

Published: Jan. 17, 2025

The current study investigated the relationship between adverse childhood experiences (ACEs), post-traumatic stress disorder (PTSD) symptoms, within-network resting-state functional connectivity (rs-FC), and alcohol use during adolescence using magnetic resonance imaging (fMRI) data from National Consortium on Alcohol Neurodevelopment in Adolescence (NCANDA; N = 687). Significant rs-FC differences emerged that linked participant ACEs, PTSD problems. Participants with ACEs compared to those without had diminished within default mode, salience, medial frontoparietal networks (p ≤ 0.005). Further reduction mode 0.005) was found when symptoms were present addition ACEs. Findings suggest are associated lower network beyond exposure some of these changes worsened problems (i.e. withdrawal symptoms). These findings highlight importance addressing adolescents a history as it may mitigate problematic brain reduce risk developing

BMC Psychiatry, Journal Year: 2025, Volume and Issue: 25(1)

Published: Feb. 27, 2025

Recent genome-wide association studies have linked voltage-gated calcium channel genes to bipolar disorder (BD), in which CACNB2 gene rs11013860 is respectively reported. Less known, though, about how precisely its polymorphism affects both the structure and function of brain. 173 BD patients 207 healthy controls (HCs) were underwent structural functional magnetic resonance imaging scan genotyped for rs11013860. Grey matter volume (GMV), regional homogeneity (ReHo) degree centrality (DC) used examine brain structure, activity connectivity these participants. The emotional circuits patients, such as cerebellum, insula, cingulate gyrus, fusiform superior frontal / middle temporal occipital lingual precuneus, putamen, hippocampus parahippocampal main areas where GMV, ReHo, DC differed from HCs. And right anterior posterior cerebellar lobes, gyrus well showed an interaction between genotypes diagnoses GMV. In addition, there was a significant step-wise increase GMV with decreased dosage A risk allele HCs, but this pattern relationship absent patients. No found ReHo DC. These results suggest that may be associated abnormalities cerebellar, limbic system other regions, perhaps contributing disease.
