Filter by:The aim of this study is to determine whether dairy or plant based fats combined with fish oils can alter skeletal muscle mitochondrial, physical, and cognitive function.
This study evaluates the efficacy of multi-odorant enrichment on cognitive skills, olfactory function, and quality of life.
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.
The investigators propose to evaluate the compliance of oral cancer therapies, particularly the possible link between this observance and cognitive function of patients at initiation of treatment. To our knowledge, this study will be among the first conducted on the issue in France and is an innovative approach in the management of cancer patients. The inclusion of cognitive dysfunction is part of a comprehensive approach to improving the quality of life and fully meets the objectives of both plans cancer, including those of the axis "Living during and after cancer" highlighted in the Cancer Plan
The purpose of this study is to test the hypothesis that aerobic exercise and a computer-based cognitive intervention leads to improved cognitive function accompanied by increases in gray matter density and changes in functional magnetic resonance imaging (fMRI) patterns of task-related activation.
