Abstract
AIMS To test differential outcomes between three 6-month text-messaging interventions to reduce at-risk drinking in help-seeking adults. DESIGN A three-arm single-blind randomized controlled trial with 1-, 3-, 6- and 12-month follow-ups. SETTING United States. A fully remote trial without human contact, with participants recruited primarily via social media outlets. PARTICIPANTS Seven hundred and twenty-three adults (mean = 39.9 years, standard deviation = 10.0; 62.5% female) seeking to reduce their drinking were allocated to 6 months of baseline 'tailored statically' messaging (TS; n = 240), 'tailored adaptive' messaging (TA; n = 239) or 'drink tracking' messaging (DT; n = 244). INTERVENTIONS TS consisted of daily text messages to reduce harmful drinking that were tailored to demographics and alcohol use. TA consisted of daily, tailored text messages that were also adapted based on goal achievement and proactive prompts. DT consisted of a weekly assessment for self-reported drinking over the past 7 days. MEASUREMENTS The primary outcome measure was weekly sum of standard drinks (SSD) at 6-month follow-up. Secondary outcome measures included drinks per drinking day (DDD), number of drinking days (NDD) per week and heavy drinking days (HDD) at 1-, 3-, 6- and 12-month follow-ups. FINDINGS At 6 months, compared with DT, TA resulted in significant SSD reductions of 16.2 (from 28.7 to 12.5) drinks [adjusted risk ratio (aRR) = 0.80, 95% confidence interval (CI) = 0.71, 0.91] using intent-to-treat analysis. TA also resulted in significant improvements in DDD (aRR = 0.84; 95% CI = 0.77-0.92) and drinking days per week (b = -0.39; 95% CI = -0.67, -0.10), but not HDD compared with DT at 6 months. TA was not significantly different from TS at any time-point, except DDD at 6 months. All groups made improvements in SSD at 12-month follow-up compared with baseline with an average reduction of 12.9 drinks per week across groups. CONCLUSIONS Automated tailored mobile messaging interventions are scalable solutions that can reduce weekly alcohol consumption in remote help-seeking drinkers over time.

Abstract
In this narrative review, we draw from historical and contemporary literature to explore the impact of alcohol consumption on brain and behavior among women. We examine three domains: 1) the impact of alcohol use disorder (AUD) on neurobiobehavioral outcomes, 2) its impact on social cognition/emotion processing, and 3) alcohol's acute effects in older women. There is compelling evidence of alcohol-related compromise in neuropsychological function, neural activation, and brain structure. Investigations of social cognition and alcohol effects in older women represent emerging areas of study. Initial analyses suggest that women with AUD show significant deficits in emotion processing, a finding also observed in older women who have consumed a moderate dose of alcohol. Critically, despite the long-recognized need for programmatic interrogation of alcohol's effect in women, studies with sufficient numbers of women for meaningful analysis represent a small proportion of the literature, constraining interpretation and generalization.

Nixon SJ, Garcia CC, Lewis B. Age as a potential modulator of alcohol-related deficits. Alcohol 2023; 107:12-18.

Abstract
Although their individual significance is well-documented, the interaction effects of age, sex, and alcohol use disorder (AUD) have undergone little systematic investigation. Here, we extend prior work interrogating sex and group (AUD vs. community comparison [CC]) by probing the main and interaction effects of age on emotion processes as well as two conventional neuropsychological tests. Main effects for age and group were anticipated; however, interaction effects comprise our primary focus. While sex differences in AUD prevalence are commonly reported, sex differences within AUD samples are inconsistently found. Therefore, we pose our inquiry regarding sex as exploratory. In this study, 54 CC (n = 30 women) and 55 AUD (n = 14 women) subjects completed a battery that included an emotional face discrimination task, the Trail-Making Test-B (TMT-B), and the Digit Symbol Substitution Test (DSST). The initial/full models included the main and interaction effects of age (as a continuous variable; 25-59 years of age), sex, and group (AUD, CC). In analysis of the emotional face discrimination task, performance on a non-affective face discrimination task was entered as a covariate. Analysis of emotion identification revealed group and age main (p = .02; d = .53 & .003; d = .50, respectively) and interaction effects (p = .05; d = .41). The latter suggested that age and emotion processing performance were positively correlated in the AUD group, but unrelated in the CC group. Notably, neither sex, main, nor interaction effects achieved significance. Using the full model, analysis of the TMT-B and DSST failed to show sex effects or reveal expected performance decrement in the AUD group. To clarify the latter, simple models including only group as well as correlations between age and performance by group for each task were conducted. These analyses demonstrated the expected AUD-related deficits and suggested differential relationships between age and neurocognitive performance as a function of both group and task. Outcomes across tasks emphasize the need to reframe aging effects, particularly in the context of AUD.

Abstract
AIM To synthesize international findings on the alcohol-dementia relationship, including representation from low- and middle-income countries. METHODS Individual participant data meta-analysis of 15 prospective epidemiological cohort studies from countries situated in six continents. Cox regression investigated the dementia risk associated with alcohol use in older adults aged over 60 years. Additional analyses assessed the alcohol-dementia relationship in the sample stratified by sex and by continent. Participants included 24 478 community dwelling individuals without a history of dementia at baseline and at least one follow-up dementia assessment. The main outcome measure was all-cause dementia as determined by clinical interview. RESULTS At baseline, the mean age across studies was 71.8 (standard deviation = 7.5, range = 60-102 years), 14 260 (58.3%) were female and 13 269 (54.2%) were current drinkers. During 151 636 person-years of follow-up, there were 2124 incident cases of dementia (14.0 per 1000 person-years). When compared with abstainers, the risk for dementia was lower in occasional [hazard ratio (HR) = 0.78; 95% confidence interval (CI) = 0.68-0.89], light-moderate (HR = 0.78; 95% CI = 0.70-0.87) and moderate-heavy drinkers (HR = 0.62; 95% CI = 0.51-0.77). There was no evidence of differences between life-time abstainers and former drinkers in terms of dementia risk (HR = 0.98; 95% CI = 0.81-1.18). In dose-response analyses, moderate drinking up to 40 g/day was associated with a lower risk of dementia when compared with lif-time abstaining. Among current drinkers, there was no consistent evidence for differences in terms of dementia risk. Results were similar when the sample was stratified by sex. When analysed at the continent level, there was considerable heterogeneity in the alcohol-dementia relationship. CONCLUSIONS Abstinence from alcohol appears to be associated with an increased risk for all-cause dementia. Among current drinkers, there appears to be no consistent evidence to suggest that the amount of alcohol consumed in later life is associated with dementia risk.

Abstract
As the percentage of the global population over age 65 grows, and with it a subpopulation of individuals with alcohol use disorder (AUD), understanding the effect of alcohol on the aged brain is of utmost importance. Neuroinflammation is implicated in both natural aging as well as alcohol use, and its role in alterations to brain morphology and function may be exacerbated in aging individuals who drink alcohol to excess. The neuroimmune response to alcohol in aging is complex. The few studies investigating this issue have reported heightened basal activity and either hypo- or hyper-reactivity to an alcohol challenge. This review of preclinical research will first introduce key players of the immune system, then explore changes in neuroimmune function with aging or alcohol alone, with discussion of vulnerable brain regions, changes in cytokines, and varied reactions of microglia and astrocytes. We will then consider different levels of alcohol exposure, relevant animal models of AUD, and neuroimmune activation by alcohol across the lifespan. By identifying key findings, challenges, and targets for future research, we hope to bring more attention and resources to this underexplored area of inquiry.

Acceptability and preliminary effectiveness of a text messaging intervention to reduce high-risk alcohol use among adults 50 and older: an exploratory study. ADVANCES IN DUAL DIAGNOSIS 2022.

Abstract
Purpose
Prevalence rates of older adults (OA, 50+) with high-risk alcohol use are rapidly growing. Barriers to intervention persist for OA. Mobile interventions, specifically short message service (SMS, also known as text messaging), provide an opportunity to overcome such barriers. The purpose of this paper is to explore the acceptability and preliminary effectiveness of four SMS intervention conditions compared to mobile assessment only among OA (50–65 years old, n = 49) who drink at high-risk levels compared to younger adults (YA, 21–49 years old, n = 102).
Design/methodology/approach
Within and between age group differences at baseline and end-of-treatment (12 weeks) were explored. Generalized linear modeling was used to test age by receipt of any SMS intervention (compared to assessment only) effects across health outcomes. Effect sizes and visual analyses were generated to assess for age by type of SMS interactions.
Findings
Both age groups reported intervention satisfaction. Two-thirds elected to continue receiving SMSs after treatment concluded. Descriptively, SMS groups demonstrated reduced drinking across age groups at end-of-treatment compared to mobile assessment only, though slightly larger effects were found for YA than for OA. Age significantly moderated the receipt of any SMS intervention only for depression (i.e., older age weakened the therapeutic effect). Of all the SMS types, tailored messages outperformed the other conditions on drinking outcomes for both age groups. Depression, craving and alcohol problems responded to gain-framed messages among OA and loss-framed messages among YA.
Research limitations/implications
The findings of this paper suggest that SMS is acceptable and potentially effective across age groups. Further adaptation of SMS across age groups could enhance its effectiveness.
Originality/value
This is the first paper to explore the impact of older age on the efficacy of text messaging as an intervention for hazardous alcohol use.

Cognitive training in recently-abstinent individuals with alcohol use disorder improves emotional stroop performance: Evidence from a randomized pilot trial. Drug Alcohol Depend 2022; 231:109239.

Abstract
BACKGROUND Cognitive training interventions appear capable of improving alcohol-associated neurobehavioral deficits in recently detoxified individuals. However, efficacy remains incompletely characterized in alcohol use disorder (AUD) and available data address only non-affective cognitive outcomes; enhancement of social cognition remains uninvestigated. We utilized a training paradigm in which successfully ignoring emotionally-valent stimuli benefitted task performance. We hypothesized trained individuals would display improvements in an affective inhibitory control task, and that individuals trained with high valence (relative to neutral) stimuli would evince greater improvement. METHODS 42 recently detoxified inpatients with AUD were assigned to one of three groups (Emotional Training, Neutral Training, or Treatment as Usual [TAU]). Training consisted of two computerized working memory tasks (dual-modality n-back task; attend/ignore task) which included task-irrelevant stimuli (emotional vs. neutral). Post-training performance efficiency (indexing speed-accuracy tradeoffs) in an emotional Stroop task was the outcome of interest. RESULTS Significant group by time interactions were detected for emotional Stroop performance, supporting our hypothesis that trained groups would exhibit greater improvement than TAU controls (F[2,39]=8.61, p < .01). Additionally, the emotional training condition appeared to result in greater improvement relative to neutral training (F[1,26]=4.98, p < .01). CONCLUSION Results are consistent with current literature suggesting the potential of training to enhance cognitive recovery in early abstinence. Findings inform the development of training protocols, suggesting integration of task-irrelevant distractor stimuli in training may enhance cognitive control outcomes. Further, they expand the relevant domains for application of training approaches, providing novel evidence that among individuals with AUD, training-associated benefits may extend to social cognitive domains.

Abstract
Insulin resistance is a key etiological factor in promoting not only type 2 diabetes mellitus but also cardiovascular disease (CVD). Exercise is a first-line therapy for combating chronic disease by improving insulin action through, in part, reducing hepatic glucose production and lipolysis as well as increasing skeletal muscle glucose uptake and vasodilation. Just like a pharmaceutical agent, exercise can be viewed as a "drug" such that identifying an optimal prescription requires a determination of mode, intensity, and timing as well as consideration of how much exercise is done relative to sitting for prolonged periods (e.g., desk job at work). Furthermore, proximal nutrition (nutrient timing, carbohydrate intake, etc.), sleep (or lack thereof), as well as alcohol consumption are likely important considerations for enhancing adaptations to exercise. Thus, identifying the maximal exercise "drug" for reducing insulin resistance will require a multi-health behavior approach to optimize type 2 diabetes and CVD care.

Abstract
PURPOSE OF REVIEW Alcohol is gaining increased recognition as an important risk factor for dementia. This review summarises recent evidence on the relationship between alcohol use and dementia, focusing on studies published from January 2019 to August 2020. RECENT FINDINGS Epidemiological data continues to yield results consistent with protective effects of low-to-moderate alcohol consumption for dementia and cognitive function. However, recent literature highlights the methodological limitations of existing observational studies. The effects of chronic, heavy alcohol use are clearer, with excessive consumption causing alcohol-related brain damage. Several pathways to this damage have been suggested, including the neurotoxic effects of thiamine deficiency, ethanol and acetaldehyde. SUMMARY Future research would benefit from greater implementation of analytical and design-based approaches to robustly model the alcohol use-dementia relationship in the general population, and should make use of large, consortia-level data. Early intervention to prevent dementia is critical: thiamine substitution has shown potential but requires more research, and psychosocial interventions to treat harmful alcohol use have proven effective. Finally, diagnostic criteria for alcohol-related dementia require formal validation to ensure usefulness in clinical practice.

Abstract
The average age of the population in many countries is continuing to increase. Older people continue to consume alcohol, often in a binge like fashion. Previous research has demonstrated that older human subjects and aged animal subjects have an increased sensitivity to the effects of ethanol on a variety of behaviors. However, it has yet to be determined if acute ethanol exposure impairs spatial and/or nonspatial memory to a greater extent in aged rats compared to adult rats. In the current studies we trained male rats ranging in age from young adult (2 months of age) to aged rats (29-33 months of age) in the standard nonspatial task followed by the standard spatial task in the Morris water maze. Only animals deemed "cognitively-spared", that is aged animals that learn as well as young animals, were administered one of two doses of moderate ethanol and had their memory tested 30 min later. Acute ethanol administration produced similar performance impairments in spatial and nonspatial memory in all cognitively-spared animals except for the 29-33 month old animals which showed a significantly greater cognitive impairment in both tasks. In addition, blood ethanol levels were similar across all ages. The present work adds to the growing literature on the selective effects of acute ethanol exposure in aged animals.

It is widely recognized that people worldwide are living longer than in previous decades, with formidable projections regarding the expansion of elderly age groups in the decades to come. Older individuals are also sustaining higher levels of alcohol consumption later in life, and binge drinking remains a prevalent pastime in a significant proportion of aged individuals. Older people are more sensitive to neurobehavioral effects of alcohol, and as individuals age, the cumulative impact of lifetime alcohol intake begins to emerge. This brief review provides a perspective on the emerging field of how alcohol interacts with the aging brain and sets the stage for understanding the relationship between alcohol and overall brain health. In doing so, we introduce a set of articles collected in this book series (all chapters available on PubMed) which spans human epidemiology and clinical outcomes, along with a series of neurobehavioral studies in preclinical (rodent) models. Because both natural aging as well as alcohol use and abuse include tell-tale signs of neuroinflammation (heightened expression of neuroimmune genes, activation of inflammatory signaling pathways, and signs of glial activation), particular emphasis is placed on the role of neuroinflammation in both aging- and alcohol-related alterations in neurobehavioral function, with special emphasis on the spectrum of cognitive dysfunction ranging from mild cognitive impairment to Alzheimer's associated brain pathology.
