Filter by:Our primary aim is to determine whether a computerized working memory (WM) training program will help students with severe learning and attention problems, in terms of improving their WM. Additional aims are to determine whether the WM training will also result in improvements in the students' concentration and school work, and how long any beneficial effects will last (i.e., whether the students will continue to show improvements once the training program has stopped).
There is some evidence that anti-inflammatory treatment may have beneficial effects in schizophrenia and major depression. Cox-2 inhibitors have been tested in preliminary clinical trials for schizophrenia and depression, showing favourable effects compared to placebo (Muller and Schwarz et al 2009). Statins were introduced as cholesterol-lowering agents but have found much wider usage. They are anti-inflammatory agents and thus similar to the Cox-2 inhibitors, which have shown some ability as adjuncts to improve the symptoms of schizophrenia in preliminary studies. The statins are also known to decrease C-reactive protein (CRP), which has been shown in an SMRI-funded study to be elevated in a study of individuals with schizophrenia. Fan et al (2007) demonstrated in a small study in patients with schizophrenia that higher than normal levels of CRP (>0.50 mg/dl) was associated with marked negative symptoms and higher total PANSS scores. Ondansetron is a serotonin (5-HT3) receptor antagonist that is generic and widely used to prevent nausea and vomiting in patients receiving chemotherapy for cancer. GSK did a small study on it as an antipsychotic in the 1980s. Since then, several small studies have suggested that it is effective as an adjunct drug in improving the symptoms of schizophrenia. Statins are widely used in schizophrenia sufferers, particularly those taking second generation antipsychotics, to treat hypercholesterolemia. Both drugs are well tolerated and their side effect profiles well understood. We propose to conduct a feasibility study in patients with chronic schizophrenia to explore the adjunct use of simvastatin and ondansetron on positive, negative and general psychopathology in comparisons to treatment as usual (TAU) over a 12 week period.
The purpose of the study is to evaluate the efficacy and safety of deep brain rTMS, (Transcranial Magnetic Stimulation), a new experimental procedure using the H-Coil, in subjects with Major Depressive Disorder that have been previously unsuccessfully treated with antidepressant medications.
This study will develop and test a treatment aimed at reducing anxiety in social situations for children and adolescents with autism spectrum disorders.
The research involves the establishment of a cohort including as much as possible cases of macrothrombocytopenia related to a "MYH9 syndrome" and the study of mutations and polymorphisms of MYH9 gene in all these patients. As MYH9 syndrome is an autosomal dominant disorder, patients should be heterozygous for a MYH9 gene mutation. The main goal of our project is looking for correlations between genotype and phenotype. It is planned to characterize the phenotype and genotype of a cohort of patients, including family members that will be addressed during the study in order to better understand the platelet disorder and improve the epidemiological knowledge of MYH9 syndrome. The data will be recorded in a database.
Representative payees, mostly family members, manage Social Security Administration funds of more than one million people with psychiatric disabilities. Although studies show payeeship can be used coercively, foster dependency, reduce work incentives, lead to family conflict and even violence, there has been little systematic research on how to lower these significant barriers to community integration. The investigators' long term goal is to promote recovery among adults with psychiatric disabilities who have payees by reducing downsides associated with what has been called "the nation's largest guardianship system." The investigators' objective in the current application is to evaluate a pilot-tested, stakeholder-informed intervention that is grounded in principles of psychiatric rehabilitation and encourages consumers with psychiatric disabilities and their family members to collaborate within the representative payee arrangement.
RATIONALE: Gathering information about human papilloma virus (HPV) infection in HIV-positive men who have sex with men may help doctors learn more about the disease. PURPOSE: This clinical trial is studying HPV infection in HIV-positive Indian men who have sex with men.
This phase II clinical trial studies how well treosulfan and fludarabine phosphate with or without low dose radiation before donor stem cell transplantation works in treating patients with nonmalignant (noncancerous) diseases. Hematopoietic cell transplantation has been shown to be curative for many patients with nonmalignant (noncancerous) diseases such as primary immunodeficiency disorders, bone marrow failure syndromes, hemoglobinopathies, and inborn errors of metabolism (metabolic disorders). Powerful chemotherapy drugs and/or radiation are often used to condition the patient before infusion of the new healthy donor cells. The purpose of the conditioning therapy is to destroy the patient's abnormal bone marrow which doesn't work properly in order to make way for the new healthy donor cells which functions normally. Although effective in curing the patient's disease, many hematopoietic cell transplantation regimens use intensive chemotherapy and/or radiation which can be quite toxic, have significant side effects, and can potentially be life-threatening. Investigators are investigating whether a new conditioning regimen that uses less intensive drugs (treosulfan and fludarabine phosphate) with or without low dose radiation results in new blood-forming cells (engraftment) of the new donor cells without increased toxicities in patients with nonmalignant (noncancerous) diseases.
The behavioral patterns, neurocognitive and social impairments, and high heritability are the common characteristics of autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD), the two most common early-onset neuropsychiatric disorders. Little is known about the discriminative validity between these two disorders. As brain imaging studies have been recognized as an important biological tool to validate disease involving the brain, no studies have employed this approach to distinguish the brain functioning between ASD and ADHD. Moreover, there is lack of comprehensive data of environmental, behavioral, neurocognitive, neuroimaging, and genetic data for healthy children. Hence, we propose this program project involving expertise researchers in the fields of child psychiatry and psychology, psychiatric genetics, and brain imaging studies to elucidate the neuropathophysiology and genes & environment interactions of ASD and ADHD as comparing to healthy controls by integrating data from environments, behavioral phenotypes, endophenotypes, and genotypes in one study.
The ultimate goal of this study is to find the association between specific polymorphism of candidate genes and medication response in attention deficit hyperactivity disorder (ADHD) patients. These results will lead the investigators' team: (1) to resolve controversies over inconsistent findings in previous pharmacogenetic studies; (2) to study the medication effect on the neuropsychological functions that are useful candidate endophenotypes for ADHD; (3) to delineate the nature and the effect of gene-gene interaction in the drug response of ADHD patients.
