Filter by:The purpose of this study is to evaluate the use of the drug isradipine for cognitive enhancement in patients diagnosed with schizophrenia and schizoaffective disorder.
The purpose of this study is to examine an Adaptive Treatment approach in order to improve outcomes of youth with Cannabis Use Disorders who are poor responders to treatment.
The purpose of this study is to use proton magnetic resonance spectroscopy (MRS) at 4 Tesla to measure brain glycine levels noninvasively at baseline and for 2 hours after a single oral dose of a concentrated glycine-containing beverage, and to compare MRS glycine measurements to glycine blood levels in samples obtained after each MRS spectrum. The investigators hypothesize that they will observe a high correlation between the magnitude increases in brain and plasma glycine levels over this time frame. The investigators also hypothesize that we will observe large intersubject variability in glycine uptake rates into brain and blood. The investigators also hypothesize that subjects with a glycine decarboxylase (GLDC) mutation (triplication) will have lower baseline plasma and brain glycine levels and will experience smaller brain and plasma glycine increases after glycine consumption than controls or family members without the GLDC mutation.
A study to examine whether an antipsychotic combination treatment of olanzapine and amisulpride is more effective than olanzapine and amisulpride alone.
The objective of this sensory analysis study is to determine whether volunteers observe a significant difference in organoleptic properties between lamotrigine (430C78) cherry flavoured orally disintegrating tablets (ODT) and a placebo cherry flavoured orally disintegrating tablet. The aim is to assess the value of the placebo as a marketing aid, whereby physicians and patients may assess the personal acceptability of the organoleptic properties and potential convenience prior to prescription of the ODT formulation.
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.
