Filter by:Background: People with psychosis show profound deficits in memory. A new cognitive remediation therapy using an app on a computer or mobile phone to improve memory has been effective in this population, but the neurobiological effects are unknown. Objectives: 1) To use functional magnetic resonance imaging (fMRI) to examine brain changes during a working memory task before and after a 12 hour memory training intervention on a computer or mobile phone, 2) To use diffusion tensor imaging (DTI) to examine white matter connecting prefrontal and parietal lobe before and after training. Methods: 46 people with psychosis will be randomized to a computerized training of either memory training or a control condition of non-memory games (language/card games) and will self-administer 4 hours of training over 4 days per week, for 3 weeks (12 hours total). Memory training will be done with the Peak app http://www.peak.net. Imaging data will be gathered with a 3 Tesla scanner pre and post training.
Preclinical and clinical data as well as mechanistic justification have been presented suggesting citicoline and pregnenolone are each promising treatments for alcohol use in BPD. Both appear to have favorable side effect profiles and no known drug-drug interactions. Thus, they have the potential to be safely used in a dual diagnosis population already taking other medications. A 12-week, randomized, double-blind, parallel-group, placebo-controlled adaptive design study of citicoline and pregnenolone is proposed in 199 persons with alcohol use disorder and bipolar I or II disorder or schizoaffective disorder (bipolar type). The primary aim will be to assess change in alcohol use. Biomarkers of alcohol use, alcohol craving, mood and cognition will also be assessed. Relationships between neurosteroid and choline levels and the outcome measures will be explored.
The purpose of this study is to determine whether the use of atypical antipsychotic medication increases the risk of hospitalization for a hyperglycemic emergency. The investigators will carry out separate population-based cohort studies using administrative health databases in eight jurisdictions in Canada and the UK. Cohort entry will be defined by the initiation of a new antipsychotic medication. Follow-up will continue until hospitalization for a hyperglycemic emergency or the end of 365 days. The results from the separate sites will be combined to provide an overall assessment of the risk of hyperglycemic emergencies among new users of various antipsychotic drugs.
A randomized controlled, prospective, two-armed, mono-centric, assessor-blinded clinical trial will serve to generate preliminary data on the efficacy and safety of modified psychodynamic therapy (MPP-S) in stabilized patients after the first or subsequent episodes of schizophrenia or schizoaffective disorder.
Antipsychotics are approved to treat several conditions, including Schizophrenia, Schizoaffective Disorder, Bipolar Disorder, and Major Depressive Disorder among others. The typical and atypical antipsychotics, derive their therapeutic benefit predominantly from the antagonism of dopamine D2 and 5-HT2A receptors. Many of these compounds are associated with common and significant adverse effects (e.g. weight gain, extrapyramidal symptoms, hyperprolactinemia, sexual dysfunction, and cardiac effects) which negatively impact on adherence. Today, antipsychotic induced weight gain (AIWG) is a leading cause for antipsychotic discontinuation. Importantly as well, approximately 20-30% of all patients with schizophrenia do not respond adequately to an initial antipsychotic trial, and strikingly, 83% of those who go on to a second antipsychotic trial do not meet criteria for response. To-date, no RCT has been conducted to evaluate the outcomes in patients taking antipsychotics following the use of pharmacogenomic guidance of treatment selections. Therefore, the rationale for this trial is to utilize a double-blinded RCT design to evaluate and compare the clinical outcomes in participants treated with the benefit of GEN and E-GEN testing. Furthermore, this trial also intends to develop an evidence- based case for the value of GEN and E-GEN to Canadian health-care payers.
The purpose of this study is to determine if a manualised intervention to promote physical activity (MoVo-LISA) is effective to help psychiatric outpatients to increase their level of everyday physical activity.
This is a randomized double-blind placebo controlled trial which aims to evaluate the efficacy and tolerability of minocycline and Omega-3 fatty acids for patients with ARMS. Specifically to determine whether the addition of minocycline and / or Omega-3 fatty acids to Treatment as Usual in an operationalized ARMS population in Pakistan:
The purpose of this study is to find out the time it takes to absorb, distribute, breakdown and remove the drug from the body, safety and tolerability of AMG 581 in healthy participants and subjects with schizophrenia.
In this study, investigators will examine the behavioral effects and neurophysiological mechanisms of the pro-social neuropeptide oxytocin in patients with recent-onset schizophrenia and other psychotic disorders. Such research is a necessary first step towards identifying whether intranasal oxytocin administration can serve as an adjunct treatment for social impairments in schizophrenia and other psychotic disorders. Aim 1: To quantify the effects of exogenous oxytocin on social cognition and behavior in patients with recent-onset schizophrenia. Hypothesis A: Patients and healthy comparison subjects will show enhanced social cognition (e.g., improved interpretation of paralinguistic and emotional cues, such as those involved in emotional or sarcastic communication) after administration of oxytocin versus placebo. Hypothesis B: Patients and healthy comparison subjects will show increased attention to others' eyes and patients will exhibit increased facial affect expressivity after administration of oxytocin versus placebo.
This study evaluates whether prospective pharmacogenetic testing is cost-effective in affecting clinical treatment outcomes in patients with early-phase psychosis.
