Filter by:The purpose of this study is to learn more about the relationship between serious mental illness and the detection and management of diabetes and pre-diabetic conditions. Patients who have been diagnosed with schizophrenia are at an increased risk for developing diabetes and pre-diabetic conditions such as impaired glucose tolerance and impaired fasting glucose. In addition, novel antipsychotics have also been linked to impaired glucose metabolism and increased incidence of diabetes. The medical management of these patients may be difficult ot achieve through standard family practice. The objectives of this project are to: screen a sample of this high-risk population using an Oral Glucose Tolerance Test (OGTT), and to provide multidisciplinary team support to those identified as having diabetes or a pre-diabetic condition.
The present study will determine if Spaniol and colleague's (1994) Recovery Workbook group intervention is an effective clinical tool to move a person with SMI along in their journey of recovery. The primary outcome measurements of this study will be the participants' perceived level of empowerment, hope and optimism, knowledge of recovery, and life satisfaction. This kind of information would add to the current body of knowledge about how principles of recovery can be used in psychoeducational programs used by outpatient community mental health services.
This is a six week, double blind,placebo controlled study for patients with schizophrenia or schizoaffective disorder treated with an atypical antipsychotic for at least two months. Subjects will be randomized to take armodafinil (Nuvigil) or placebo along with their current antipsychotic and tested at baseline and week 6 for differences in memory, attention and problem-solving ability. Changes in weight during the six week study will also be tracked.
It has been suggested that patients with schizophrenia smoke in order to produce amelioration of dysfunctional dopaminergic pathways allowing them to experience pleasure and satisfaction and overcome anhedonia. No studies have assessed the effects of nicotine withdrawal on reward responsivity in patients with schizophrenia. The investigators believe that an understanding of this is crucial if improved treatments for nicotine dependence are to be developed for this patient population. If this group already has deficits in reward responsivity as a symptom of the disease then they may be particularly prone to the effects of nicotine withdrawal on reward systems. Smoking cessation may lead to a further decrease in their responsivity to pleasurable stimuli and worsening anhedonia. Treatments for smoking cessation may need to ameliorate any increased deficits if they are likely to be effective in patients with schizophrenia.
The purpose of this research study is to see how well patients in an early phase of their illness respond to treatment and whether this depends on how well they functioned socially, academically and vocationally before becoming ill. The study also examines whether patients with more insight into their illness have better outcomes.
This randomized controlled trial examined whether an abbreviated treatment using abstinence contingency management for housing and work/training (CM, n=103) with cocaine dependent, non-psychotic, dually diagnosed homeless persons, would show non-inferior outcomes compared to the full treatment (CM+, n=103). It was hypothesized that CM+ would show superior abstinence and retention outcomes, but that CM, with components derived from previously effective behavioral day treatment, would obtain non-inferior outcomes, defined as 75% or more of those observed for the full treatment (CM+) during active treatment months 1-6. The CM+ included all CM components but added behavioral day treatment that included voucher reinforcement of $7.50-15.00, for objective weekly therapeutic goal attainment in five domains of functioning: drug dependence, homelessness, unemployment, non-drug related recreational activities, and behavioral, health, or mental health problems. Abstinence was assessed by observed urine specimen collection and weekly testing weeks 1-52, and randomly, bi-monthly for months 13-18. Abstinence, homelessness, employment and other outcomes were also assessed at baseline, 2, 6, 12, and 18 months.
Medications like olanzapine have been associated with the development of weight gain and diabetes in some patients. It is not known if the increased risk of developing diabetes is a direct effect on insulin or simply related to weight gain. We hope to learn in this study whether or not olanzapine directly slows down insulin secretion from the pancreas, thereby increasing the risk of developing diabetes.
Purpose of Study: A) To improve outcome in large population of antipsychotic patients with schizophrenia or schizoaffective who are only partial responders B) To increase understanding of pharmacology and mechanisms of action underlying antipsychotic effect Hypothesis/Objectives of the Study: Tetrabenazine, through its pre-synaptic action, should augment the post-synaptic effects of an antipsychotic. Background and Rationale for the study: Preliminary evidence that other amine-depleting agents e.g., reserpine, can induce such an effect
The aim of the project is to investigate the use of Raloxifene (a new form of estrogen) in the treatment of women with schizophrenia and schizoaffective disorder. Raloxifene is a Selective Estrogen Receptor Modulator (SERM), which means that it can affect the central nervous system (CNS) effects of estrogen (eg. improving emotional symptoms, memory, information processing and concentration), without adversely affecting reproductive tissue/organs such as breast, uterus and ovaries. The investigators are conducting a double-blind, placebo controlled, three month study comparing the psychotic symptom response of women with schizophrenia in both groups. One group will receive standard antipsychotic medication plus 120mg Raloxifene, while the second group will receive standard antipsychotic medication plus oral placebo. Hypothesis 1: That the women receiving adjunctive Raloxifene would have a quicker recovery from psychotic symptoms, as measured on the rating scales, compared with the women receiving adjunctive placebo. Hypothesis 2: That the Raloxifene group would have better cognitive improvement than the placebo group.
OBJECTIVE: To test the use of adjunctive estrogen in a 8 week, three-arm, double-blind, placebo-controlled study in the treatment of psychotic symptoms in women with schizophrenia. HYPOTHESIS: That women receiving adjunctive estrogen will demonstrate significantly greater improvements in the symptoms of schizophrenia than women receiving adjunctive placebo. STUDY POPULATION: 180 women will be recruited over a three-year period across three sites. Participant will be of potential child-bearing age (Pre-menopausal and Post-menarche) with a current diagnosis of Schizophrenia, Schizophreniform Disorder, or Schizoaffective Disorder (not in manic phase)according to the Mini International Neuropsychiatric Interview (MINI). STUDY MEDICATION: Estradiol. One third of the participants (n=60) will be randomised to receive adjunctive 100mcg Estradiol; one third of the participants (n=60) will be randomised to receive adjunctive 200mcg Estradiol n=60; and, one third of the participants (n=60) will be randomised to receive adjunctive placebo n=60). All patches will be covered with identical adhesive contact to ensure the "blind" is maintained. STUDY EVALUATIONS: Data will be collected over a two-month period for each participant. Visits will be performed at baseline, and then at weekly or fortnightly intervals. A total of six visits will be completed for each participant. The following evaluations will be performed: i) Inclusion/exclusion checklist. (Baseline visit only) ii) Informed consent. (Baseline visit only) iii)psychiatric evaluation to determine diagnosis. (Baseline visit only) iv) General clinical evaluation including medical history, current conditions and a non-invasive physical examination, body weight, vital signs. (Baseline and endpoint visits) v) Medication history. (Baseline and evaluation visits) vi) Demographics. (Baseline visits only) vii) The primary outcome measures will be the Positive and Negative Syndrome Scale (PANSS), which will be taken at weeks 1, 2, 4 and 8 of the trial. Cognitive testing will take place at baseline and 8 weeks. Side effects will be assessed at weeks 1, 2, 4, 6, and 8 to measure changes in subject's reported side effects during the trial. viii) Laboratory tests including; Serum levels of mood stabiliser, LH, FSH, Estrogen, Progesterone, Prolactin, DHEA,Testosterone and(Baseline and evaluation visits).
