The study suggests that the link between impulsivity and high-risk drinking is more nuanced than commonly understood. The profiles, described in &lt;i&gt;Alcohol: Clinical and Experimental Research&lt;/i&gt;, may give health care providers a framework to personalize interventions more effectively to prevent harms related to alcohol use.&lt;/p&gt;&lt;p&gt;People with impulsive personalities tend to be highly emotionally reactive or act without sufficiently considering potential consequences. Impulsivity is associated with high-risk drinking and substance use, but not all impulsive individuals engage in problem drinking. Researchers for this study sought to identify any particular characteristics of impulsive personalities that distinguished those who engage in risky drinking behaviors from those who do not.&lt;/p&gt;&lt;p&gt;Two hundred participants recently treated for psychiatric symptoms underwent comprehensive assessments of personality traits, cognitive function, psychological symptoms, risk-taking behaviors, and alcohol consumption patterns. Analyzing all the data, researchers identified three personality profiles. A ‘low risk’ profile had low levels of both impulsivity and alcohol use disorder. An ‘emotionally reactive’ profile was highly impulsive but had low levels of alcohol use disorder symptoms. And a ‘high risk’ profile, had both high impulsivity and high levels of alcohol use disorder symptoms.&lt;/p&gt;&lt;p&gt;Each profile displayed distinguishing characteristics that guide clinical treatment to reduce the risk of problematic alcohol use. For example, the emotionally reactive group scored higher in neuroticism and lower in conscientiousness, suggesting interventions targeting emotion regulation, such as cognitive-behavioral therapy. Individuals in this group also scored higher on ‘fun-seeking’ and may better engage with interventions that incorporate novelty and stimulation. The high-risk group exhibited cognitive deficits on performance-based tasks reflective of impairments in decision-making and reward sensitivity, which are associated with substance use disorders. Treatment tailored to this group might include cognitive remediation therapies to improve deficits in memory, attention, problem-solving, and executive function.&lt;/p&gt;&lt;p&gt;The findings suggest that incorporating personality assessments into personalized treatment plans that address individual differences in personality and cognitive ability may more effectively prevent and treat problem alcohol use.&lt;/p&gt;&lt;p&gt;Profiles of impulsivity and alcohol use: Unveiling personality, cognitive traits, and DSM diagnoses.

To investigate the impact of PAE on OB RGCs, BrdU was injected 30 min prior to ethanol administration to label OB RGCs in the S phase of the cell cycle. The location and differentiation of BrdU⁺ cells were subsequently examined in the developing OB at E11, E13, and E15. We also assessed whether inhibition of GABA(A) receptors could mitigate the effects induced by PAE.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>PAE was found to impair the progression of migration of OB RGC nuclei to the apical side of the ventricular zone for mitosis, indicating the inhibition of the transition from the S phase to the M phase (G2/M arrest). Therefore, PAE delays neurogenesis of OB RGCs. Importantly, our findings suggest that GABAergic signaling mediated by the mTOR signaling plays a critical role in these PAE-induced effects.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>These findings provide insights into the mechanisms by which PAE disrupts OB development by impairing neurogenesis of RGC, contributing to a better understanding of the underlying mechanisms of olfactory dysfunction observed in FASD.</p>\u0000 </section>\u0000 </div>","PeriodicalId":72145,"journal":{"name":"Alcohol (Hanover, York County, Pa.)","volume":"49 11","pages":"2494-2501"},"PeriodicalIF":2.7,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/acer.70161","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145034780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our objective was to explore gender differences in AUD treatment outcomes among older adults, focusing on continuous measures (e.g., drinks per day) and binary measures (e.g., abstinence) across a 1-year period.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We analyzed data from a multinational randomized controlled trial involving 693 older adults (60+) diagnosed with DSM-5 AUD. Participants received motivational enhancement therapy and the community reinforcement approach, across sites in Denmark, Germany, and the United States.

Gender–time interactions showed smaller reductions in females' drinks per day and drinks per drinking day (<i>p</i> &lt; 0.05), resulting in similar drinking levels at follow-ups. No gender differences were found at any time points for percent days abstinent and percent heavy drinking days (<i>p</i> ≥ 0.05). A significant gender–time interaction was found for percent days abstinent (<i>p</i> = 0.04), but no consistent direction was observed across time points. For abstinence and no heavy drinking, no gender differences were found (<i>p</i> ≥ 0.05). No interactions between gender and time were found for any binary outcome (<i>p</i> ≥ 0.05).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Among older adults with DSM-5 AUD diagnosis, treatment led to substantial and sustained improvements across genders. While women showed less favorable drinking reductions, adjusted estimates were broadly comparable. Given women's increased physiological vulnerability to alcohol, this may not imply equivalent clinical risk. Still, findings support the potential for meaningful treatment benefits regardless of gender.</p>\u0000 </section>\u0000 </div>","PeriodicalId":72145,"journal":{"name":"Alcohol (Hanover, York County, Pa.)","volume":"49 11","pages":"2553-2566"},"PeriodicalIF":2.7,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/acer.70164","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145034752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
