Stress is likely involved in relapse to cocaine use. This project will investigate the role oxytocin may play in the stress response in cocaine-dependent men and women and examine how oxytocin may impact brain activity in individuals exposed to cocaine-related cues.
Previous studies suggest that pregnenolone may inhibit the intoxicating effects of marijuana and reduce drug-seeking behavior. In this study we are examining the effects of pregnenolone on craving and mood in response to marijuana cues. In addition we are examing the effects of pregnenolone on blood levels of endogenous endocannabinoids.
The purpose of this pilot study is to investigate alterations in neural activity among individuals with Tourettes Syndrome. This will be acheived with single-pulse transcranial magnetic stimulation (TMS) and magnetic resonance imaging (MRI). These techniques are non-invasive. TMS is a brain stimulation method that allows us to measure the speed of information processing between brain regions as well as between the brain and the muscles. Combine with MRI, these techniques allow us to create a dynamic image of brain activity which may help guide future treatments. It is important to note that this will be used for research purposes and is not diagnostic.
The Sleep Research Data Repository (SRDR) aimed to systematically collect, analyze and store for future research sleep and sleep disorders related biological and psychological information. It will include sleep physiological measurements and the results of interviews, questionnaires, and laboratory tests. The SRDR will contain sleep related information obtained from healthy subjects and patients with psychiatric, substance abuse, neurological disorders, or any medical conditions associated with sleep disturbances. SRDR data will be made available to current and future IRB-approved investigators associated with this protocol.
This study is designed to evaluate the efficacy, safety, and tolerability of ALKS 3831 in schizophrenia with AUD. ALKS 3831 is a combination of olanzapine, an approved antipsychotic treatment for schizophrenia, and samidorphan, a new medication. Potential subjects for this trial are adults with a diagnosis of schizophrenia and alcohol use disorder (AUD) with a recent change in symptoms. The study will test whether olanzapine with samidorphan will aide in lowering alcohol use for subjects at the same time that the combination of the two drugs lessens side effects of olanzapine such as weight gain.
Social stress often leads to drug craving and relapse in cocaine-dependent populations. Currently there are no FDA approved medications for the treatment of cocaine dependence. Therefore, biomedical research studies aimed at investigating the brain mechanisms responsible for controlling emotional responses to social stress could have a significant impact on the development of effective therapeutic treatment strategies for cocaine-dependent individuals.
The study will involve a randomized controlled trial (RCT) with subjects ages 13-18 years (who have experienced sexual assault) randomized to receive Risk Reduction through Family Therapy (RRFT) or Treatment As Usual. Youth will be recruited from 2 local child advocacy centers and the interventions are psychosocial in nature. Follow-up assessments will be conducted at multiple time points through 18-month post entry.
The goal of this pilot study is to determine if, in substance dependent individuals, a single session of transcranial magnetic brain stimulation (TMS) over a brain region involved in craving (medial prefrontal cortex) can lower an individual's craving and brain response to drug-related cues. This study involved a screening visit, followed by two visits which involve brain imaging (using functional MRI) and brain stimulation (using TMS). There is also an additional Magnetic resonance spectroscopy (MRS) substudy with a unique consent form which invites participants back for a third MRI scanning visit in which we will measure the concentration of glutamate in the mediap prefrontal cortex before and after a session of TMS.
