Filter by:The investigators propose a test of causality by examining a cohort of patients undergoing deep brain stimulation (DBS) within the ventral striatum. The investigators will examine behavior on and off stimulation across a range of tasks that index different forms of impulsivity. Patients will be studied in both the ON and OFF state - that is, they will be tested during active deep brain stimulation and 30 min to 1 hour after stimulation has been stopped (order of state will be counterbalanced across subjects). The investigators specific aim is to test the hypothesis that enhancing ventral striatal signaling (i.e. ON-state DBS) will cause more impulsive patterns of behavior across several impulsivity tasks. The investigators predict that ventral striatal DBS will increase stop-signal reaction time on the stop-signal task and commission errors on the Go/NoGo task, and increase delay aversion in a delay discounting paradigm.
This is a proposed home visitation program for families of children with externalizing behaviors who are on the wait list for psychiatric assessment at BC Children's hospital. The aim of this program is to implement and evaluate a home visitation strategy in order to support those waiting up to four months to consult a psychiatrist.
In a randomized, double-blind controlled trial the investigators will evaluate the efficacy of rTMS in reducing impulsivity for cocaine addicts through - Quantitative and qualitative analysis - such behavior and possible behavioral consequences related.
This is a pilot study to examine the acceptability and effectiveness of the Re-Entry Values and Mindfulness Program (REVAMP), a group intervention for jail inmates. It is hypothesized that REVAMP will reduce post-release recidivism, substance abuse, and HIV risk behavior.
This will be a randomized, double-blind, placebo-controlled, dose-ranging, efficacy and safety study in children with impulsive aggression comorbid with Attention-Deficit/Hyperactivity Disorder (ADHD). The target subjects are healthy male and female children aged 6 to 12 years, inclusive, with a diagnosis of ADHD. A total of 120 subjects will be randomized across approximately 30 US centers to one of four treatment groups.
Dependence on tobacco derived nicotine is a major public health problem. Substance users who complete training in mindfulness subjectively report increased patience and improved motor control over their impulses. Yet, no studies have tested this perceived benefit with behavioral measures of impulse control. The investigators are conducting a randomized controlled clinical trial, which compares Cognitive-Behavioral Therapy and Mindfulness Training for tobacco smokers, using behavioral measures to investigate the effects of mindfulness training on impulsivity and inhibitory control.
In this study, we seek to understand the effects of tolcapone, an FDA-approved COMT inhibitor, on reward choice and response inhibition, two measures we have previously shown to be altered in subjects with alcoholism. We now plan to test the hypothesis that COMT regulation of cortical dopamine levels is critical for regulation financial choices. Specifically, we propose that the lower levels of cortical dopamine present in individuals with the val158val COMT genotype reduces the inhibitory effect of frontal cortical areas on impulsive choice; an idea that extends previous hypotheses about the negative consequences of decreased prefrontal dopamine levels on inhibitory control. Moreover, this hypothesis suggests that inhibiting COMT may slow the degradation of dopamine and thereby decrease impulsivity.
The goal of this pilot feasibility and utility study is to develop and validate a method that is reproducible over time for assessing biobehavioral and autonomic markers of impulsivity and their utility in assessing treatment outcome in preschool children with ADHD.
The purpose of this study is to assess neurocognitive and associated neural regions/circuitry disruptions relevant to impulsive relapse in cocaine-addicted subjects, and the relationship of the cognitive and neural mechanisms of impulsivity/decision-making to relapse style.
The purpose of the this study is to compare pathological gamblers versus non-pathological gamblers using tests that measure different components of impulsivity. We aim to invite a total of 120 individuals to participate in this study. Impulsivity has been described as the cognitive inability to delay gratification, a failure to inhibit behavioral action or acting without forethought about consequences. Impulsivity has also been seen as a personality trait characterized by risk-taking or sensation seeking behavior. Pathological gamblers demonstrate aspects of impulsivity; they act without thinking, have difficult inhibiting urges to gamble and desire immediate gratification. The goal of this project is to clarify which components of impulsivity are associated with pathological gambling. Non-treatment seeking, pathological gamblers and controls will be recruited from the community and local casinos. Each participant will be administered a battery of tests that represent different operational definitions of impulsivity.
