Alcohol use disorder (AUD) is prevalent during young adulthood, and this risk may be linked to aberrations in neurodevelopmental processes. Prior studies examining white matter (WM) integrity in young adult individuals with AUD have shown considerable variability. This is due in part because traditional tensor related metrics such as fractional anisotropy are subject to limitations in estimation precision at sites of crossing or curving fibres. In response, to better understand differences in WM integrity of young adults with AUD, this study sought to uniquely employ two WM integrity measurement domains. Methods. Twenty-five participants (<i>n =</i> 14 female) diagnosed with AUD and 33 social drinkers (<i>n =</i> 19 female) underwent structural and diffusion-weighted imaging. Diffusion-weighted images were processed to extract diffusion tensor (DTI) and neurite orientation dispersion and density (NODDI) metrics in major WM tracts for comparison between the two groups. Results. We identified decreased axial diffusivity in portions of frontolimbic and corticostriatal WM tracts, and increased orientation dispersion at overlapping tracts in participants with AUD relative to social drinkers. Conclusions. These results may represent early-stage neural immune system activation and axonal reorganization targeting frontolimbic and corticostriatal WM tracts, therein associated with behaviours linked to AUD. This is the first study combining DTI and NODDI metrics to identify early-stage indicators of alcohol-related neurobiological pathology in young adults with AUD compared to social drinkers.</p>","PeriodicalId":7289,"journal":{"name":"Addiction Biology","volume":"30 3","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11924133/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143664975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Interestingly, CRYAB is expressed in oligodendrocytes in the NAcc of mice. Extracellular CRYAB levels are regulated by cocaine and stress hormone treatments in oligodendrocyte cultures. Dopamine levels in the NAcc and CPP development of CPP are significantly increased by cocaine in CRYAB knockout (KO) mice. Further, we demonstrated that CRYAB binds to the excitatory amino acid transporter 2 (EAAT2) in the NAcc of mice treated with cocaine.

Addiction research has consistently revealed significant modifications in key brain networks related to reward, habit, salience, executive function, memory and self-regulation. Techniques like Voxel-based Morphometry have highlighted large-scale structural differences in grey matter across distinct groups. Source-based Morphometry (SBM) takes this a step further by incorporating the Independent Component Analysis to detect shared patterns of grey matter variation, all without requiring prior selection of regions of interest. However, SBM has yet to be employed in the study of structural alteration patterns related to cocaine addiction. Therefore, we performed this analysis to explore alterations in structural covariance specific to cocaine addiction. Our study involved 40 individuals diagnosed with Cocaine Use Disorder (CUD) and 40 matched healthy controls. Participants with CUD completed clinical questionnaires assessing the severity of their dependence and other relevant clinical variables. Following the adjustment for age-related effects, we observed notable disparities between groups in two structural independent components, which we identified as the structural cerebellar network and the structural lateral frontoparietal network, which display opposing trends. Specifically, the individuals with CUD exhibited a heightened contribution to the cerebellar network but simultaneously demonstrated a reduced contribution to the lateral frontoparietal network compared to the healthy controls. These findings unveil distinctive covariance patterns of neuroregulation linked with cocaine addiction, which indicates an interruption in the typical structural development in an affected lateral frontoparietal network, while suggesting an extended pattern of neuroregulation within the cerebellar network in individuals with CUD.</p>","PeriodicalId":7289,"journal":{"name":"Addiction Biology","volume":"30 3","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/adb.70021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In alcohol use disorder (AUD), implicit alcohol-related associations have been shown to predict increased subsequent alcohol consumption and are linked to the risk of relapse. Explicit cognitive processes, exerting prefrontal top-down control, are particularly significant during the critical period following the decision to abstain. This study aims to map implicit and explicit cognitive processes in recently abstinent individuals with AUD and to explore the effect of cathodal transcranial direct current stimulation (tDCS) on implicit associations by modulating top-down control. In this preregistered, double-blind, sham-controlled clinical trial, 30 abstinent individuals with AUD participated in two experimental sessions. They received either 2 mA cathodal tDCS to the left dorsolateral prefrontal cortex (dlPFC) or sham tDCS in a crossover design. During tDCS, participants completed the alcohol approach implicit association test (IAT) and the drinking identity IAT, along with two control tasks. Additionally, we collected explicit ratings of the IAT stimuli and assessed craving before and after each experimental session. Preregistered ANOVAs revealed significant implicit alcohol–avoidance and non–drinking identity biases. Cathodal tDCS did not modulate IAT scores. Explicit ratings showed a preference for non-alcoholic drinks and non-drinking identity, correlating moderately with IAT scores. Exploratory analyses indicated that cathodal tDCS mitigated the increase in nicotine craving during the experimental session. This preregistered clinical trial provides robust evidence that single-session cathodal tDCS to the left dorsolateral prefrontal cortex does not modulate implicit associations in AUD, with Bayesian analyses corroborating the absence of tDCS effects. Our results emphasize the impact of contextual factors on the interplay between explicit and implicit cognitive processes and underscore the importance of investigating multisession stimulation paradigms in future research.</p>","PeriodicalId":7289,"journal":{"name":"Addiction Biology","volume":"30 3","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/adb.70029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143595005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we enrolled 25 chronic cannabis users and 30 demographically matched non-users who completed an interview probing current and past substance use, a urinalysis to confirm self-reported substance use and a task-switch cognitive paradigm during magnetoencephalography (MEG). Time-frequency windows of interest were identified using a data-driven statistical approach, and spectrally specific neural oscillatory responses were imaged using a beamformer. The resulting maps were grand-averaged across all participants and conditions, and the peak voxels in these maps of neural oscillatory activity were used as seeds to compute connectivity using a whole-brain cortical-coherence approach. Whole-brain neural switch cost connectivity maps were then computed by subtracting the connectivity map for the no-switch condition from that of the switch condition per participant. These switch cost functional connectivity maps were then correlated with the behavioural switch cost per group and probed for group differences in the neuro-behavioural associations. Our behavioural results indicated that all participants had slower reaction times during switch compared to no-switch trials. Regarding the MEG data, cannabis users exhibited altered associations between functional connectivity switch costs and behavioural switch costs along pathways connecting visual cortices and regions in the ventral attention network, within the theta, alpha and gamma frequency ranges.

An additional highly suggestive QTL was present on chromosome 9 for the difference in pre- and post-ethanol thermal nociception. Candidate genes within QTL support intervals were provisionally identified using HP phenotypic correlations to transcriptomic database, expression QTL analysis and other bioinformatics inquiries. The combined behavioural and bioinformatic analyses yielded strong ethanol analgesia candidate genes, specifically <i>Myo6</i>.

Yet, these factors have not been assessed as potential predictors of future drinking behaviour. Here, in a longitudinal study we collected fMRI data in 50 drinkers who, at baseline, performed a probabilistic learning go/nogo task that involved proactive avoidance of painful electric shocks. Pain-related psychological measures and the neural correlates of proactive avoidance were examined in relation to participants' alcohol use and craving in the following 12 months. We found that deficits in proactive avoidance were associated with future drinking severity. Importantly, diminished activation of the dorsal anterior cingulate cortex (dACC) during proactive avoidance also predicted subsequent percentage of heavy drinking days. Using Bayesian network modelling, we established a potential pathway in which drinkers' heightened pain sensitivity led to greater pain-avoidance drinking motive and alcohol craving. Both craving and weakened dACC activation to proactive avoidance predicted higher levels of drinking during the follow-up period.
