Filter by:In this translational research proposal, based on our formulation, we seek to confirm and expand upon data obtained in our pilot study suggesting that cannabis and the cannabinoid agonist dronabinol, given in low dose to patients with schizophrenia and co-occurring cannabis use disorder, will in fact ameliorate the brain reward circuit dysregulation in these patients and, thereby, provide evidence in support of the role of cannabis as a "self-medication" agent for them.
Many individuals with schizophrenia also suffer from marijuana addiction that worsens their problems related to schizophrenia. Most of the medications prescribed for schizophrenia have no effect on reducing marijuana use. Preliminary data suggests that clozapine, an atypical antipsychotic, may limit marijuana use in people diagnosed with schizophrenia, but it is not commonly used due to its side effects and is reserved for people who do not respond to other antipsychotic medications. In the proposed study, 132 individuals who are diagnosed with both schizophrenia and a cannabis use disorder will be randomized to a 12-week treatment course with either clozapine or risperidone (another commonly prescribed antipsychotic medication) to test the hypothesis that patient treated with clozapine will have decreased cannabis use as compared to patients treated with risperidone. Should this study indicate that clozapine will lessen marijuana use in persons diagnosed with schizophrenia more than risperidone, it will provide evidence needed to begin to shift clinical practice toward its use in this population.
Methamphetamine (MA) is a psychostimulant drug with high abuse potential. MA can be smoked, snorted, injected or ingested orally to produce a release of high levels of dopamine into the brain and reduction of dopamine uptake. Its use results in feelings of pleasure, increased energy, and greater alertness lasting up to 12 hours. In 2010, the National Survey on Drug Use and Health reported that 353,000 Americans aged 12 or older reported being current MA users. Over the past decade MA use rates have fluctuated with current use rates on the decline; however, importantly, even though overall use rates are declining, use rates among males and females are approaching equal proportions. This use rate pattern is unlike other drugs of abuse, which typically demonstrate males using more than females. In some states, more females than males consider MA as their drug of choice. Namely, in a 2010 report in the state of Utah, more females were diagnosed with MA as a primary substance of abuse than males upon admission to treatment. Depression and MA use are highly comorbid. The relationship between MA use and depression is likely bidirectional, with MA use causing changes in mood and being used as a self-medicating behavior to reduce symptoms of depression. Several studies have shown that depression rates are higher in MA-using females compared to their male counterparts. It is likely that neurobiological and psychosocial mechanisms contribute to increased incidence of depressive symptoms in females. No clear treatment model exists to suggest how the comorbidity of depression and MA use is best managed. In studies of antidepressants for treatment of MA withdrawal and dependence, findings have suggested that antidepressants are ineffective for treating depressive symptoms. Creatine is an organic acid occurring naturally in vertebrates, where it takes part in energy homeostasis in tissues with fluctuating energy demands. Exogenous creatine has been shown to increase brain concentrations of PCr. Neuroimaging studies of creatine have shown increased brain phosphocreatine (PCr) content with creatine administration. Therefore, we hypothesize that oral creatine administration will increase PCr levels and reduce depressive symptoms in a sample of depressed female MA users. This hypothesis will be tested by a within subjects design by giving depressed MA using females oral creatine for eight weeks and measuring PCr pre- and post-treatment with magnetic resonance spectroscopy. Moreover, depressive symptoms will be measured by administration of the Hamilton Depression Rating Scale twice weekly during the course of creatine treatment.
Note: In June 2013, the study design was changed from a randomized controlled study of risperidone + despiramine vs. risperidone vs. placebo to an open label pre-post study of risperidone (or risperidone-like drug) + desipramine. The aims of the study were revised to read: 1. To determine whether participants treated with risperidone in combination with desiprmaine have less alcohol use (fewer drinking days; fewer heavy drinking days) during the final 8 weeks on these medications as compared to pre-baseline. The primary hypothesis is that compared to pre-baseline, participants will demonstrate fewer days of drinking (per week), as well as fewer days of heavy drinking (per week) in the final eight weeks they are taking risperidone and desipramine, as recorded on the Timeline Follow-Back assessment 2. To explore changes in symptoms (of schizophrenia and of depression) in the final eight weeks of treatment with risperidone + desipramine compared to the period before baseline 3. To assess the side effect burden associated with the combination of these two medications in participants. The original aims of the study were: The purpose of this study is to determine whether participants who are treated with risperidone in combination with desipramine have less alcohol use (fewer drinking days; fewer heavy drinking days) than do participants who are treated with RISP with placebo. The primary hypothesis is that compared to treatment with risperidone, participants randomized to a combination of risperidone plus desipramine will have fewer days of drinking, as well as fewer days of heavy drinking. The study will also compare the effects of risperidone as compared to risperidone plus desipramine on participants' symptoms and side effects.
This stage 1 clinical trial will determine pilot efficacy, develop a therapy manual, and collect qualitative data concerning a brief money management intervention for people disabled by psychiatric illnesses.
Randomized clinical trial comparing a money management-based intervention involving storage and management of client funds, substance abuse counseling, and risk reduction counseling to individualized drug counseling.
The Norwegian Social and Welfare Act of 1992, opened for compulsory commitment of patients with serious alcohol and drug problems to inpatient care. Clinical research of compulsory committed dual diagnosed patients is to date unavailable and is demanded by the health authorities of Norway. Because there has been limited examination/screening and no post-treatment research efforts on this group of patients, the investigators have limited knowledge of the treatment as well as the patient group. Do compulsory treated patients differ from those voluntarily admitted? Does this type of treatment influence the patients' motivation to change their behaviour, and does the treatment effort lead to positive outcome effects in the long run? The primary aim is to acquire new and in depth descriptive knowledge about the compulsory treated group of patients according to: Drug dependence, psychiatric and somatic co-morbidity and socio-demographic characteristics, and investigate whether the treatment yields the intended outcomes in terms of improved substance abuse measures. A second aim is to compare the group with a corresponding group of voluntarily admitted patients within the same wards. A follow-up interview focusing on motivational issues within 6 months post treatment to evaluate the long-term results of the treatment is planned. A quasi-experimental, prospective case-control study will be conducted. Compulsory committed patients in five counties during a two year period, will be compared to a group of voluntarily admitted patients. The groups will be compared regarding 1) description and screening 2) motivation to change and 3) outcome results after 6 months. Both official authorities as well as clinical practitioners would benefit from valid Norwegian results and knowledge within this field to form further policies and evidence based best practice for this vulnerable group of patients.
The first aim of this study is to determine whether a brain reward center (BRC) deficiency in patients with schizophrenia (SCZ) and cannabis use disorder (CUD) will be normalized when patients are given cannabis or dronabinol. The second aim will serve to further assess the effects of dronabinol on symptoms and medication side effects in this population.
Two approaches for providing evidence-based substance abuse treatment (EBT), group motivational interviewing (GMI) and the In-Home-Messaging-Device (IHMD), are interventions that have the characteristic ability for increasing accessibility to evidence-based treatment among patients with substance use problems and are proposed for investigation. GMI is based on motivational interviewing, an intervention that has shown consistent significant effects in promoting treatment retention and reduced substance use among individuals with substance use disorders, and is delivered in a group format. IHMD is a user-friendly computerized Tele-mental Health communication tool that allows interaction through the telephone line between a Veteran and the health care provider in an individual's home or residential placement. The current proposal aims to determine whether GMI and IHMD lead to a significantly greater increase in treatment engagement and reduction in alcohol use compared to a treatment control condition (TCC) among Veterans with a substance use problem and a co-existing psychiatric disorder.
Many individuals with schizophrenia also suffer from marijuana addiction. Clozapine, an atypical antipsychotic medication, may prove useful at preventing drug relapse in schizophrenic individuals who are seeking treatment for marijuana addiction. The purpose of this study is to compare the effectiveness of clozapine, vs. treatment-as-usual with other oral antipsychotics at reducing marijuana use in schizophrenic individuals.
