BACKGROUND Alcohol use disorder has been associated with diverse physical and mental morbidities. Among the main consequences of chronic and excessive alcohol use are cognitive and executive deficits. Some of these deficits may be reversed in specific cognitive and executive domains with behavioral approaches consisting in cognitive training. The advent of computer-based interventions may leverage these improvements, but RCTs of digital interactive-based interventions are still scarce. OBJECTIVE The aim is to explore whether a cognitive training approach using virtual reality exercises based on activities of daily living is feasible for improving cognitive function of patients with alcohol use disorder undergoing residential treatment, as well as to estimate the effect size for this intervention to power future definitive RCTs. METHODS A two-arm pilot randomized controlled trial with a sample of 36 individuals recovering from alcohol use disorder in a therapeutic community assigned to a therapist-guided virtual reality-based cognitive training combined with treatment-as-usual or a control group with treatment-as-usual without cognitive training. A comprehensive neuropsychological battery of tests was used both at pre and post assessments, including global cognition, executive functions, attention, visual memory and cognitive flexibility. RESULTS In order to control for potential effects of global cognition and executive functions at baseline, these domains were controlled in the statistical analysis for each individual outcome. Results indicate effects (P < .05) of the intervention on attention (in 2 out of 5 outcomes) and cognitive flexibility (in 2 out of 6 outcomes), with effect sizes in significant comparisons being larger for attention than for cognitive flexibility. Patient retention in cognitive training was high, in line with previous studies. CONCLUSIONS Overall data suggest specific contributions of reality-based cognitive training in improving attention ability and cognitive flexibility of patients recovering from alcohol use disorder.

The use of ecologically oriented approaches with virtual reality (VR) depicting instrumental activities of daily living (IADL) is a promising approach for interventions on acquired brain injuries. However, the results of such an approach on dementia caused by Alzheimer’s disease (AD) are still lacking. This research reports on a pilot randomized controlled trial that aimed to explore the effect of a cognitive stimulation reproducing several IADL in VR on people with mild-to-moderate dementia caused by AD. Patients were recruited from residential care homes of Santa Casa da Misericórdia da Amadora (SCMA), which is a relevant nonprofit social and healthcare provider in Portugal. This intervention lasted two months, with a total of 10 sessions (two sessions/week). A neuropsychological assessment was carried out at the baseline and follow-up using established neuropsychological instruments for assessing memory, attention, and executive functions. The sample consisted of 17 patients of both genders randomly assigned to the experimental and control groups. The preliminary results suggested an improvement in overall cognitive function in the experimental group, with an effect size corresponding to a large effect in global cognition, which suggests that this approach is effective for neurocognitive stimulation in older adults with dementia, contributing to maintaining cognitive function in AD.

AbstractIdentification of new medications for alcohol use disorder (AUD) is important for improving treatment options. Baclofen, a GABAB agonist, has been identified as a potential pharmacotherapy for AUD. In a 16-week double-blind, randomized, placebo-controlled trial, we investigated 30 and 90 mg/day of baclofen compared to placebo and examined effects of dose, sex, and level of pretreatment drinking. One hundred and twenty participants with DSM-IV alcohol dependence (age 46.1 (sd = 10.1) years, 51.7% male) were randomized after exclusion for unstable medical/psychiatric illness and/or dependence on drugs other than nicotine. Seventy-three participants completed the trial. A main effect of baclofen was found [%HDD (F(2,112) = 4.16, p = 0.018, d = 0.51 95%CI (0.06–0.95), 13.6 fewer HDD) and %ABST (F(2,112) = 3.68, p = 0.028, d = 0.49 95%CI (0.04–0.93), 12.9 more abstinent days)] and was driven by the 90 mg/day dose. A sex × dose interaction effect was present for both %HDD (F(2,110) = 5.48, p = 0.005) and %ABST (F(2,110) = 3.19, p = 0.045). Men showed a marginally positive effect for 90 mg/day compared to PBO (%HDD t(110) = 1.88, p = 0.063, d = 0.36 95%CI (−0.09–0.80), 15.8 fewer HDD days; %ABST t(110) = 1.68 (p = 0.096, d = 0.32 95%CI (−0.12–0.76), 15.7 more ABST)) with no effect for 30 mg/day. Women showed a positive effect for 30 mg/day (%HDD, t(110) = 3.19, p = 0.002, d = 0.61 95%CI (0.16–1.05), 26.3 fewer HDD days; %ABST t(110) = 2.73, p = 0.007, d = 0.52 95%CI (0.07–0.96), 25.4 more ABST days) with marginal effects for 90 mg/day on %ABST (p = 0.06) with drop-outs/dose reduction from sedative side-effects of 59% in women at 90 mg/day compared to 5% for men. These findings support the hypothesis that baclofen has efficacy in AUD and suggest that dose and sex be further explored as potential moderators of baclofen response and tolerability.

Aim: The aim of this study is to compare the effect of exercise training on physical capacity and alcohol consumption in alcohol use disorder (AUD) patients. Methods: One hundred and five AUD patients were randomly assigned to treatment as usual combined with running and brisk walking for 30–45 min twice a week, either in small supervised groups (GR) or individually (IND), or to a control group with no running (C). Assessments were made after 6 and 12 months of training. Results: Training volume was estimated as 36 min per training bout at an intensity of 78% of HRmax with no differences between GR and IND ( p>.05). A highly significant reduction in training frequency was seen in both training groups after the first month ( p<.0001). Only IND increased VO2max, by 5.7% ( p<.05), while no differences were seen between GR, IND and C. Alcohol intake decreased from 219 to 41 units per 30 days as the average for the entire sample with no significant difference of drinking outcomes between groups ( p<.0001). Conclusions: We saw an effect on drinking habits after running in both groups. However, no additional effect was seen when compared with the control group. A drop in the training frequency during the intervention might have resulted in an insignificant training stimulus.
