Cognition clinical trials at UC Health
4 in progress, 2 open to eligible people

  • D2D Normative Data for Remote Assessments

    open to eligible people ages 12-80

    Phase 1: This is a remote observational study in which participants will complete cognitive assessments developed by Posit Science. Participants will be healthy controls aged 18-65 with reliable internet access and a device that they can use to access the assessments, such as a laptop or iPad. Participants will complete up to 6 Posit Science assessments in different domains of cognition, which should last approximately 30 minutes. Phase 2: This is an in person observational study in which participants will complete cognitive assessments developed by Posit Science. Participants will be healthy controls aged 18-80 who are fluent in English. Participants will complete batteries of cognitive assessments developed by Posit Science, which include combinations of visual, auditory, and social cognitive assessments, and self-report questionnaires. This study will be conducted at the Driven to Discover building at the Minnesota State Fair. Participation will last approximately 20 minutes. Phase 3: Participants in Phase 3 will complete a Posit Science assessment battery and self-report questionnaires. Each participant will be asked to provide brief demographic and medical history data. Participants will be aged 18-35 and will be students at the University of Minnesota who are enrolled in the Research Experience Points program. Participants will complete the assessment battery remotely; the battery will take approximately 45-60 minutes to complete. Phase 4: This is a pilot program to test the use of remote cognitive assessment and training in adolescents with an anxiety diagnosis and healthy controls. Participants will complete a short assessment battery, then will receive 4 hours of cognitive training over 2 weeks at home. Then they will repeat the battery. Total participation should last approximately 5 hours over 2-3 weeks and will be completed entirely remotely.

  • Dopamine D2/D3 Receptor Upregulation by Varenicline in Methamphetamine Users

    Sorry, accepting new patients by invitation only

    While deficits in dopamine D2-type receptor availability have been linked to substance use disorders, higher availability associates with better behavioral treatment outcomes for stimulant dependence and resilience to addiction. Varenicline has been shown to upregulate D2-type receptors in drug-naive rats, and could be a useful therapeutic approach for the treatment of addictive disorders in humans. The purpose of the study is to assess the relationship between varenicline, dopamine signaling (specifically, D2-type receptor availability), functional connectivity within corticostriatal circuitry, genetic markers associated with smoking and methamphetamine abuse, and measures of cognitive performance. The investigators hypothesize that varenicline but not placebo will upregulate (increase) striatal dopamine D2-type receptor availability and improve cognition, and that the change in availability will correlate with the change in cognition. The investigators also hypothesize that varenicline but not placebo treatment will repair dysregulated connectivity between the striatum and prefrontal cortex observed in methamphetamine users, and will correlate with the change in cognition. The study design consists of two positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) scans to measure dopamine D2-type receptor availability and functional connectivity between the prefrontal cortex and striatum, two cognitive testing sessions including a battery of tests assessing working memory, declarative memory, sustained attention, inhibitory control, and reward-based decision making. Following eligibility screening, thirty six methamphetamine users will be enrolled and tested/scanned once prior to initiation of varenicline or placebo treatment and then again after completion of treatment.

  • Improve your well-being and try a self-experimentation tool

    “Help us understand how self-experimentation tools can be designed to improve health and well being”

    Sorry, in progress, not accepting new patients

    The project will enroll up to 10,000 adult volunteers in individualized experiments (N-of-1 trials) designed to assess the individual-level effects of any of five interventions on three outcomes. The five interventions are: gratitude journaling, mindfulness meditation, random acts of kindness, physical activity, and laughter therapy. The three outcomes are stress, cognitive focus, and happiness. Each participant will engage in the selected activity in 3 day intervals, separated at random by 3 day intervals of usual activity, for a total of six 3-day periods (18 days).
