Filter by:Lifetime risk for developing an alcohol use disorder increases with earlier onset of alcohol consumption. This risk may reflect a tendency for escalated alcohol intake among youth due to immature executive control, leading to more frequent binge drinking, which is associated with more alcohol-related problems. Binge drinking is associated with deficits in behavioral flexibility, which may suggest impaired control networks that contribute to automatic behavior. Individuals with an alcohol or substance use disorder (A/SUD) exhibit attentional bias toward drug- or alcohol-related stimuli that have attained salience through consistent use. Reward history increases attention towards non-drug stimuli, even among individuals with no lifetime A/SUD. Preliminary data (from Dr. Boettiger's lab) from a nationally representative US adult sample using data collected via Prolific found that a questionnaire measure of mindfulness moderates the relationship between alcohol misuse and attention to reward. Given evidence that heavy alcohol drinking impairs behavioral flexibility, which in turn promotes escalating intake, insight into the relationship between mindfulness and behavioral flexibility could inspire new strategies to prevent alcohol and substance use disorders in people at elevated risk.
Over 50% of adults with HIV have some form of HIV-Associated Neurocognitive Disorder (HAND) which represents a significant symptom that interferes with everyday functioning and quality of life. As adults age with HIV, they are more likely to develop comorbidities such as cardiovascular disease, hypertension, and insulin resistance which will further contribute to poorer cognitive functioning and HAND. Based upon the Frascati criteria, HAND is diagnosed when a person performs less than 1 to 2 SD below their normative mean (education & age) on measures of two or more cognitive domains (e.g., attention, speed of processing, verbal memory, executive functioning). Yet, from the cognitive literature and prior studies, administering certain computerized cognitive training programs may improve specific cognitive domains in older adults and those with HIV. Such cognitive training programs may be effective in older adults with HIV and therefore investigators may be able to change the diagnosis of HAND in such cognitively vulnerable adults. In this pre-post experimental study, 146 older adults (50+) with HAND will be randomized to be in either: 1) the Individualied-Targeted Cognitive Training, or 2) a no-contact control group. The investigators will focus on those cognitive domains in which participants express an impairment and train them with the corresponding cognitive program. Such an Individualized-Targeted Cognitive Training approach using standard cognitive training programs may offer hope and symptom relief to those individuals diagnosed with HAND. Furthermore, these changes may result in improved everyday functioning (e.g., IADLs) and quality of life. This approach represents a paradigm shift in possibly changing the way HAND is examined. Specific Aim 1: Compare adults who do receive Individualized-Targeted Cognitive Training to those who do not in order to determine whether a change in HAND prevalence and severity occurs between groups. Exploratory Aim 1: Compare adults who do receive individualized-targeted cognitive training to those who do not in order to determine whether this improves everyday functioning (e.g., IADLs). Exploratory Aim 2: Determine whether improvements in HAND and/or everyday functioning over time mediate improvements in quality of life.
