Filter by:The purpose of this study is to measure the effectiveness and assess the safety of two dosages of the antipsychotic paliperidone extended-release (ER) in patients who are experiencing an acute episode of schizoaffective disorder.
The aim of the protocol is to study the effects of 320 mg/day of ziprasidone (Geodon) on glucose and lipid metabolism of patients with both Diabetes Type II (DM) and schizophrenia or schizoaffective disorder, after switching their antipsychotic medication/s from typical and/or atypical to ziprasidone monotherapy.
The aim of this study is to evaluate the effectiveness, safety, and tolerability of metformin treatment in children and adolescents suffering from weight gain secondary to use of atypical antipsychotic medications. In this 12 week, open-label study we will investigate metformin's effects on weight control and/or weight loss. We hypothesize that metformin would prevent further weight gain or lead to weight loss, resulting in amelioration of one of the most significant side effects of atypical antipsychotic use.
The purpose of this study is to compare three strategies for switching patients with schizophrenia or schizoaffective disorder to the atypical antipsychotic, risperdone, after they have been unsuccessfully treated with another atypical antipsychotic, olanzapine. In the second phase of this study, investigators will assess the effectiveness of behavioral therapy in reducing body weight in risperdone-treated patients who are overweight or have problems with diabetes or blood sugar.
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.
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).
