Our aim was to explore the aberrant intrinsic functional topology in methamphetamine-dependent individuals after six months of abstinence using resting-state magnetic imaging (rs-fMRI). Eleven methamphetamines (MA) abstainers who have abstained for and eleven healthy controls (HC) were recruited rs-fMRI examination. The graph theory connectivity (FC) analysis employed investigate brain between two groups at multiple levels. Compared with HC group, characteristic shortest path length ($ {L}_{p} $) showed a significant decrease global level, while efficiency {E}_{glob} local {E}_{loc} an increase considerably. After FDR correction, we found group differences nodal degree regional level ventral attentional network (VAN), dorsal (DAN), somatosensory (SMN), visual (VN) default mode (DMN). In addition, NBS method presented aberrations edge-based FC, including frontoparietal (FPN), subcortical (SCN), VAN, DAN, SMN, VN DMN. Moreover, FC large-scale networks revealed within SCN networks. These findings suggest that some functions, e.g., processing skills, object recognition memory, may not fully recover withdrawal. This leads possibility relapse behavior when confronted MA-related cues, which contribute explaining mechanism. We also provide basis revealing neural mechanism MA-dependency abstinence.

Abstract Study Objectives This study aimed to investigate the alterations in resting-state electroencephalography (EEG) global brain connectivity (GBC) patients with chronic insomnia disorder (CID) and explore correlation between macroscale connectomic variances microscale neurotransmitter distributions. Methods We acquired 64-channel EEG from 35 female CID 34 healthy females. signals were source-localized using individual anatomy orthogonalized mitigate volume conduction. Correlation coefficients band-limited source-space power envelopes of DK 68 atlas computed averaged across regions determine specific GBC values. A support vector machine (SVM) classifier utilizing features was employed differentiate controls. further used Neurosynth a 3D receptors/transporters assess cognitive functions landscape associated cortical abnormality maps, respectively. Results exhibited elevated within medial prefrontal cortex limbic cortex, particularly at gamma carrier frequency, compared controls (pFDR < .05). patterns found effectively distinguish precision 90.8% SVM model. The maps significantly correlated meta-analytic terms like “cognitive control” “emotion regulation.” Notably, profiles (pspin .05), systems such as norepinephrine, dopamine, serotonin making significant contributions. Conclusions work characterizes profile CID, facilitating cost-effective clinical translation EEG-derived markers. Additionally, linkage distribution offers promising avenues for developing targeted treatment strategies CID.

Importance Sleep disorders and mild cognitive impairment (MCI) commonly coexist in older adults, increasing their risk of developing dementia. Long-term tai chi chuan has been proven to improve sleep quality adults. However, adherence extended training regimens can be challenging. Repetitive transcranial magnetic stimulation (rTMS) is a neuromodulation technique that may enhance the benefits exercise. Objective To investigate whether 1-Hz rTMS right dorsolateral prefrontal cortex could clinical improving function among adults with MCI. Design, Setting, Participants This 2-arm, sham-controlled, assessor-masked randomized trial was conducted at university hospital China between October 2022 February 2024. Adults aged 60 75 years MCI were eligible. Data analysis performed from May Intervention 1:1 ratio an experimental group (tai rTMS) or sham rTMS). Each participant received 30 sessions personalized targeting cortex, underwent same procedure. The 2 groups minutes 24-form simplified chuan, 5 times per week for 6 weeks. Main Outcomes Measures primary outcomes subjective assessed by Pittsburgh Quality Index (PSQI), which scores range 0 21, lower indicating healthier quality, global Montreal Cognitive Assessment (MoCA), 30, higher less impairment. secondary included measures objective actigraphy, anxiety depression scales, other subdomains. Assessments baseline, weeks after intervention, 12-week follow-up. Results A total 110 participants (mean [SD] age, 67.9 [4.6] years; 68 female [61.8%]) (n = 55) intention-to-treat analysis. At compared group, showed PSQI score (between-group mean difference, −3.1 [95% CI, −4.2 −2.1]; P < .001) MoCA 1.4 0.7-2.1]; .001). per-protocol dataset analyses follow-up similar results. generalized estimated equation model revealed interaction effect −2.1 −0.1]; 0.9 0.1-1.6]; .01). There 7 nonserious, unrelated adverse events (experimental group: 2; 5) no significant difference groups. Conclusions Relevance In this trial, findings suggest enhanced MCI, related alterations neural plasticity.

Objective Adolescents with major depressive disorder (MDD) exhibit abnormal dynamic functional connectivity (dFC) patterns, but it remains unclear whether these aberrant dFC patterns are linked to antidepressant treatment. The aim of this study is investigate will be changed by treatment, as well baseline pattern could predict treatment response in adolescent MDD patients. Method We included 35 drug-naïve, first-episode adolescents (age 14.40 ± 1.24; 8 males and 27 females) 24 healthy controls (HCs, age 14.21 1.41; 11 13 females). All received 6 weeks Resting state T1 MRI data were collected before after HCs. Independent component analysis (ICA) was used compare the different between HCs at baseline, which adolescents. Finally, Pearson correlation multivariate linear regression analyses explore associations score BDI Results mean value right inferior frontal gyrus (IFG) bilateral insular cortex (IC; right, r = −0.461, p -FDR 0.012; left, −0.518, 0.007) negatively correlated reduction. left pole (FP) superior parietal lobule (SPL) positively reduction ( 0.442, 0.014).

Abstract Background The basal nucleus of Meynert (BNM), a primary source cholinergic projections to the cortex, plays key roles in regulating sleep-wake cycle and attention. Sleep deficit is associated with impairment cognitive emotional functions. However, whether or how circuit, sleep, cognitive/emotional dysfunction are inter-related remains unclear. Methods We curated Human Connectome Project data explored BNM resting state functional connectivities (rsFC) relation sleep deficit, based on Pittsburgh Quality Index (PSQI), performance, subjective reports states 687 young adults (342 women). Imaging were processed published routines evaluated at corrected threshold. assessed correlation between rsFC, PSQI, clinical measurements Pearson regressions their inter-relationships mediation analyses. Results In whole-brain age alcohol use severity as covariates, men showed lower rsFC posterior cingulate cortex (PCC) PSQI score. No clusters identified women same Both BNM-PCC score significantly correlated anxiety, perceived stress, neuroticism scores men. Moreover, analyses that mediated relationship these measures negative emotions bidirectionally Conclusions PCC. Negative related through poor quality.

Introduction Insomnia is a common comorbidity symptom in major depressive disorder (MDD) patients. Abnormal brain activities have been observed both MDD and insomnia patients, however, the central pathological mechanisms underlying co-occurrence of patients are still unclear. This study aimed to explore differences spontaneous activity between with without insomnia, as well different level insomnia. Methods A total 88 first-episode drug-naïve including 44 (22 high 22 low insomnia) healthy controls (HC), were enrolled this study. The depression evaluated by HAMD-17, adjusted HAMD-17 its sleep disturbance subscale all subjects. Resting-state functional structural magnetic resonance imaging data acquired from participants then preprocessed software DPASF. Regional homogeneity (ReHo) values regions calculated REST compared. Finally, receiver operating characteristic (ROC) curves conducted determine abnormal for identifying evaluating severity Results Analysis variance showed that there significant ReHo left middle frontal gyrus, pallidum, right superior medial gyrus rectus among three groups.
