Filter by:Even in the absence of a preliminary diagnosis of Attention Deficit Hyperactivity Disorder, symptoms of attention deficit, hyperactivity and cognitive impairment are common in cocaine addicts. Several factors indicate that repetitive transcranial magnetic stimulation might be a strategy to aid in the treatment of symptoms of attention deficit hyperactivity disorder and cognitive function in cocaine addicts. However, up to current days there have been no studies evaluating the effects of Repetitive Transcranial Magnetic Stimulation (rTMS) on neurocognitive performance of individuals suffering from the ADHD.
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.
The medication modafinil has been shown to reduce cocaine use in some cocaine users. The investigators have shown that modafinil taken in the morning improves sleep in chronic cocaine users. The investigators hypothesize that the beneficial effects of modafinil in reducing cocaine use may be related to specific effects modafinil has on sleep. This study will measure sleep and cocaine use in cocaine dependent persons who are trying to stop using cocaine, and will test the connection between modafinil's effects on sleep and cocaine use.
The purpose of this study is to gather systematic clinical data on whether aripiprazole, a partial dopamine agonist, beneficially affects schizophrenia plus cocaine dependence subjects. Since aripiprazole has established effects against schizophrenia, the study focuses on whether aripiprazole concurrently reduces co-morbid cocaine dependence in schizophrenia plus cocaine dependence sufferers compared to a standard typical antipsychotic treatment (perphenazine). The working hypothesis states that subjects in the aripiprazole treatment arm of the study will give fewer cocaine positive urine specimens as compared to the perphenazine control arm.
This study tests the effectiveness of two 24 month, telephone-based adaptive continuing care interventions for patients with cocaine dependence. The two interventions are predicted to produce better drug use outcomes than standard care. Furthermore, the intervention that also includes monetary incentives for continued participation is hypothesized to produce better retention and drug use outcomes than the intervention without incentives. Economic analyses will determine the cost-effectiveness and benefit-cost of the interventions relative to standard care, and to each other.
The hypotheses of this study are: 1. Ondansetron will show a decrease in cocaine use from baseline in individuals with HIV who are cocaine using. 2. Ondansetron will show a decrease in cravings from baseline in individuals with HIV who are cocaine using. After informed consent and screening, HIV infected individuals who are cocaine dependent and qualify for the study will be offered ondansetron 4mg BID for six weeks in an open label format 4mg BID has been found to have efficacy compared to placebo. At screening and then at each visit, they will be asked to provide urine and a drug of abuse screen will be conducted to assess for cocaine. They will be asked to detail their recent cocaine use in the last month and then will be given a visual analog scale to assess their craving for cocaine. They will be asked to return weekly for 6 weeks to receive a week's supply of ondansetron and to give a urine sample that will test for cocaine. They will fill out a time line follow back for the past week and asked to assess their craving for cocaine on a visual analog scale.
The aim of this study is to assess the efficacy of caffeine compared to placebo as a maintenance treatment for cocaine dependence. Caffeine potentiation with biperiden will be also studied. Ninety patients with snorted/sniffed cocaine dependence will be randomized to receive caffeine (300 - 1200 mg t.i.d.) plus biperidene (8 mg b.i.d.) caffeine (300 - 1200 mg t.i.d.) with placebo or placebo during 10 days in an in-hospital setting.
The purpose of this study is to evaluate the effects of Topiramate and Cognitive Behavioral Therapy for the treatment of alcohol and cocaine dependence.
The overarching goal of this project is to have a consolidated consent and evaluation procedure that will lead potential subjects to the most appropriate clinical trial or human laboratory study (and its consent process) for their presenting concerns or interests. A second purpose is to have a consolidated intake data base on which secondary analyses can be conducted.
The purpose of this study is to determine whether patients with the greatest loss of dopamine transmission due to cocaine dependence at pre-treatment PET and MRI scans will be those who fail to respond to substance abuse treatment. This study will also determine whether patients who do respond to treatment will experience a recovery of dopamine function.
