Filter by:In this study, participants with schizophrenia and schizoaffective are given computer exercises to complete. The goals of the study are to determine whether: 1) any of the computer exercises can improve information processing problems in schizophrenia, 2) improvements in information processing are related to other cognitive improvements, and 3) there are changes in brain activity associated with using the computer exercises. The study will involve clinical interviews, cognitive tests, and frequent computerized cognitive training over the course of 2 months. Some participants will also have electroencephalography, a non-invasive test that measures brain activity, to determine whether there are changes in brain activity with the computer training.
The goal of this study is to develop an intervention to teach activation skills to Latino parents who bring children for mental health services.
In the present pilot study the feasibility and efficacy of Baby Triple P- an antenatal parent training- are investigated. Healthy becoming first time parents were randomly allocated to either the Baby Triple P parent-training group or a care as usual control group. It is expected that 78 couples of becoming first time parents are recruited. It is hypothesized that parents and their infants in the parent training group will show significantly less psychopathology / regulation problems and better partnership quality than participants in the control condition.
The overall purpose of this study is to determine whether a family history of psychosis is associated with an altered cannabinoid system. This will be tested by studying individuals with and without a family history of psychosis and comparing their responses to delta 9-tetrahydrocannabinol (THC), a probe of the cannabinoid system. We hypothesize, that compared to controls with no family history of psychoses, individuals with a family history of psychoses will have an altered response to THC.
Since 1990s, stimulation of prefrontal cortex (PFC) has shown therapeutic effects on auditory hallucinations as well as negative symptoms of schizophrenia. However, previous studies have reported mixed or negative results. Majority of the repetitive transcranial magnetic stimulation (rTMS) studies to date has set the target of cortical stimulation based on scalp site. Recently introduced method, navigated transcranial magnetic stimulation (nTMS) integrates the individual MRI data, and thus allows more precise targeting on brain cortical regions enhancing the efficacy of rTMS. Previous EEG studies have suggested reduced alpha band activity in patients with schizophrenia. Some recent studies using alpha (α) EEG guided TMS for treating positive and negative symptoms of schizophrenia have demonstrated promising results. The aim of the study is to investigate the efficacy of navigated individualized αTMS in treatment-resistant patients with schizophrenia. Approximately fifty patients with DSM-IV schizophrenia will be enrolled in this randomized, double-blind, sham-controlled study. The patients will receive 13 - 15 session of αTMS to the left dorsolateral prefrontal cortex (DLPFC), as adjunctive therapy, for 3 weeks. We assess patients via the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression (CGI) and neurocognitive test battery at baseline, 5 days after and 3 months after treatment. Serum and plasma levels of brain derived neurotrophic factor (BDNF) are assayed at pre and post treatment weeks.
Evidence-based clinical treatments for common mental disorders, such as CBT and/or pharmacotherapy, have resulted in significant and sustained improvement in clinical symptoms. However, the individual-focused treatments rarely have sickness absence as a target of intervention or evaluate work-related outcomes, such as return to work. A recent review of the evidence for managing stress at work showed that individual interventions give effects on mental health measures but did not impact absenteeism at work. The purpose of this study is to examine the efficacy and cost-effectiveness of two different rehabilitation models, one based on psychotherapy and the other on workplace-interventions, when these are offered as standalone interventions and in combination for patients with adjustment, anxiety and depressive disorders.
Presently no generally effective treatments for tardive dyskinesia (TD) are available. D-serine is a naturally occurring amino acid that acts in-vivo as positive allosteric modulator at the glycine site associated with the glutamatergic NMDA receptor. Previous studies have suggested that D-serine may improve motor symptoms, including dyskinesias, which are caused by treatment with presently used antipsychotics drugs. The hypothesis under investigation in the present study is that D-serine adjuvant treatment may improve TD in schizophrenia patients diagnosed with this disorder.
As mental health care shifted from state psychiatric hospitals to the community in France and western countries, the mental health system became inevitably involved in housing as it strove to meet the broader psychosocial needs of consumers. Simultaneously, as many consumers found themselves unable to find stable living in the community and struggling with addictions, they became a significant subgroup within a larger homeless population, which has received increasing policy attention over the past three decades. There are two distinct service models for adults who have severe mental illness and are homeless: the residential continuum model and the Housing First model.
Several observations have been made with magnetic resonance imaging (MRI) that characterize brain connections and brain function in individuals with schizophrenia and other mental disorders. For example, research investigating schizophrenia focuses on the dysfunction of connections within and between the medial temporal lobe and the prefrontal cortex as well as other pertinent brain regions. This database registry will allow for the collection of clinical interview data, behavioral data, blood, magnetic resonance imaging (MRI) data, and functional magnetic resonance imaging (fMRI) data on individuals with and without mental disorders to better understand how connections in the brain and various brain regions function differently while volunteers perform various cognitive tasks. This is an observational study that is being conducted to collect data and place it in a registry for current and future investigational questions related to imaging in mental disorders.
The purpose of this study is to examine if psychotherapy can reduce sickness absence.
