Filter by:Negative symptoms and cognitive deficits are two partially-related features of schizophrenia which have a major negative impact on social function and objective quality of life. Standard drug treatments have little impact on either and arguably no effect on primary negative symptoms. Social dysfunction has major economic consequences in both the developed and developing world. There is evidence that anti-inflammatory treatment may have beneficial effects in patients with schizophrenia.
The primary aim of this application is to conduct a randomized, controlled clinical trial of a specialized mental health service delivery system specifically developed for prodromal psychotic disorders. The intervention is Family-aided Assertive Community Treatment (FACT). The goal of the treatment is prevention of psychosis and disability. This study will assess experimentally the clinical effectiveness of this new type of mental health service. Other domains of outcome include cognitive dysfunction and functional disability.
Electroconvulsive therapy (ECT) has unparalleled efficacy in treating severe depression, and is also useful in treatment-refractory cases of schizophrenia and obsessive compulsive disorder (OCD). However, its use is limited by significant adverse effects on memory and cognition. In addition, ECT cannot be precisely targeted, since it relies on unpredictable pathways of electrical conduction through the brain. Magnetic seizure therapy (MST) is currently under investigation as a targetable, cognition-sparing alternative to ECT. MST uses magnetic fields rather than electrical stimuli for seizure induction, dramatically reducing the passage of induced current through undesired brain regions. 10 years of experimental studies have established the safety of MST in animal and human subjects. This pilot study will investigate whether MST has similar efficacy to ECT, with fewer cognitive side effects, in patients with severe depression, schizophrenia, and OCD.
The primary aim of this proposal is to develop, refine, manualize and assess the feasibility and preliminary efficacy of a brief, narrowly-focused social cognitive intervention for individuals with psychosis. The intervention will focus on helping individuals interpret social situations, specifically the intentions and feelings of others. Study methods include preliminary treatment and manual development based on series of uncontrolled cases, manual refinement, and a small feasibility/efficacy trial of the newly developed intervention.
This is a 12-week, open-label trial of salsalate 3 g/day as an adjunctive treatment in 15 schizophrenia subjects to examine salsalate's effect on psychopathology, cognitive functioning, and metabolic parameters. Potential subjects will be identified by their clinicians at the Freedom Trail Clinic, or Massachusetts General Hospital. A total of 15 subjects will be enrolled.
Multifamily group psychoeducation [MFG] and group cognitive behavioral therapy [GCBT] are evidence-based treatments for first episode psychosis. However, like all treatments for psychotic disorders, neither MFG nor GCBT are perfect—some individuals who receive these interventions still experience a worsening of psychotic symptoms. Clarifying the mechanisms through which these interventions produce their clinical benefits and identifying the factors that may maximize an individual's response to MFG and GCBT could improve the clinical benefits facilitated by these two interventions.
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.
The aim of this study is to determine the clinical, genetic and environmental factors associated with the phenotype "severe psychotic symptoms" caused by cocaine.
The purpose of this study is to compare the effects of CBT and MMI on the quality of life and relief of psychological symptoms of patients with common mental disorders or problems attending primary health care centre.
There is growing evidence of high rates of substance use disorders among individuals with psychotic disorders especially in young people with predisposition for psychosis. There is some genetic evidence that carriers of the valine158 allele of the catechol-O-methyltransferase (COMT) gene had increased risk to exhibit psychotic symptoms and to develop schizophrenia if they used cannabis by the age of 18. It was also shown that carriers of the COMT val/val genotype were most sensitive to THC-induced psychotic experiences but this was conditional on pre-existing susceptibility to psychosis. The investigators propose to use brain-imaging and molecular genetics to investigate whether genetic factors may contribute to the THC-induced dopamine release and possibly to cannabis- induced psychosis.
