NCT00845572
This study will establish a bi-weekly Consta Club. Participants will begin taking Risperdal Consta after being recommended by their treating physician. As a part of the Consta Club attendees will receive their injection of Risperdal Consta and be educated about important mental health issues. Interviews with study participants will be completed every three months to determine the effectiveness of the change to Risperdal Consta and the bi-weekly group. The overall hypothesis is that the individuals in Consta Club will have a decrease in walk-in visits, emergency procedures and hospitalizations. It is also believed that individuals in Consta Club will have fewer symptoms and better levels of functioning.
NCT00538070
The NMDA receptor has been identified as having a role in substance use disorders as well as in schizophrenia. One example of the former is nicotine's effect on dopaminergic activity not only by increasing the release of dopamine in the Midbrain reward centers, but also through less direct mechanisms affecting alpha-7 nicotinic receptors, NMDA receptors, and Glycine, a co-agonist for the NMDA receptors. In terms of schizophrenia, it has been hypothesized that NMDA receptor hypofunction plays a role in the mechanism for negative symptoms and cognitive dysfunction in these patients. The NMDA hypofunction may be reversed with increased synaptic glycine availability. Sarcosine, or n-methyl-glycine, is a GlyT-1 and System A transport inhibitor actions which could be expected to increase the availability of glycine, in the synaptic space. Sarcosine is a dietary supplement which could be found in several food items such as egg yolks and turkey. Our collaborative team has developed a novel, non-invasive magnetic resonance spectroscopy (MRS) technique for measuring brain glycine changes that allows us to study glycine homeostasis. The purpose of this study is to explore the effect of sarcosine (n-methyl-glycine) on brain glycine concentrations. It is our hypothesis that oral sarcosine, at a dose of 2 grams per day, will be well tolerated and associated with increased brain glycine concentrations. It is our secondary exploratory hypothesis that increases in brain glycine will be associated with behavioral signs of increased NMDA and dopamine activity. This modulation could have future therapeutic potential for disorders of hedonic and cognitive function.
