Filter by:Obsessive-compulsive disorder (OCD) affects 2-3% of the population and leads to a great deal of suffering. Many patients benefit from established treatments, the mainstay of which are cognitive behavioral therapy and a group of antidepressant medications known as serotonin reuptake inhibitors. However, 20-30% of patients get minimal benefit from these established therapeutic strategies. New avenues of treatment are urgently needed. Existing medications for obsessive-compulsive disorder affect the neurotransmitters serotonin or dopamine; but increasing evidence suggests that functional disruptions of a different neurotransmitter, glutamate, may contribute to some cases of OCD. The researchers are therefore interested in using medications that target glutamate as novel treatment options for those OCD patients who do not benefit from established treatments. One such medication is the drug N-Acetylcysteine, whose glutamatergic antagonistic properties may be effective in reducing the glutamatergic hyperactivity that is thought to contribute to the pathophysiology of OCD and major depressive disorder (MDD). Riluzole, which is FDA approved for amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease) is also a glutamatergic agent. There is evidence that riluzole possesses anti-depressant, anti-obsessional, and anti-anxiety properties. The modulation of glutamatergic activity is a promising new approach to the treatment of mood disorders. The researchers are therefore now recruiting patients to participate in a double-blind, placebo-controlled trial of N-Acetylcysteine, added to whatever other OCD medications they are taking.
This project represents the first randomized clinical trial of psychotherapy for older veterans with posttraumatic stress disorder (PTSD). It will compare relaxation training (RT) to prolonged exposure therapy (PE). The project will also examine whether cognitive impairment influences psychotherapy outcome. Primary hypotheses: (1) Subjects in the PE condition will have significantly less severe PTSD symptoms, depressive symptoms, and functional impairment than subjects in the RT condition at posttest; (2) Executive functioning will modify the response to both treatments, such that those with impaired executive functioning will demonstrate a smaller reduction in PTSD symptoms (representing less clinically significant change).
Having a diagnosis of schizophrenia or bipolar disorder and being treated with certain of the newer antipsychotics are risk factors for development of diabetes. Subjects with these risk factors plus obesity and/or family history of diabetes who agree to study participation will undergo an oral glucose tolerance test. If the oral glucose tolerance test demonstrates that the subject is pre-diabetic (elevated glucose levels, but below the diabetic range), he/she will have his/her insulin resistance level measured, prior to random assignment to either stay on current antipsychotic medication or switch to ziprasidone. Insulin resistance will be measured again after four months. The primary hypothesis is that insulin resistance will decrease in those switched to ziprasidone relative to those continuing on their same antipsychotic medication.
This study is being done to look at the electrical activity of the heart. This study will help decide whether taking recordings for a 24-hour period gives more useful information than recording it for a few seconds in a doctor's office. The study will compare 24 hour electrocardiogram (ECG) results of patients taking thioridazine (Mellaril) to those of other patients taking different medications that took part in another study.
To compare the efficacy of pregabalin and gabapentin, as adjunctive therapy in subjects with partial seizures.
This study is a test of cognitive behavioral therapy(CBT) and behavioral weight loss (BWL) treatments for obese patients with binge eating disorder (BED). The study involves a comparison of three treatment conditions: (1) CBT; (2) BWL, and (3) a sequential (two-part) treatment consisting of CBT followed by BWL.
The purpose of this study is to evaluate the tolerability and safety of paliperidone ER (extended-release) in doses between 3 milligrams per day and 12 milligrams per day in the treatment of patients with schizophrenia or schizoaffective disorder and liver disease.
This study is being carried out to see if extended release quetiapine fumarate (Seroquel®XL) when added to standard selective serotonin reuptake inhibitor (SSRI) / serotonin-norepinephrine reuptake inhibitor (SNRI) therapy is effective and safe for the treatment of Generalized Anxiety Disorder in patients with partial or no response to SSRI/SNRI alone or in combination with a benzodiazepine, and if so, how it compares with placebo
Allogeneic stem cell transplantation may provide long-term remissions for some patients with hematological malignancies. However, allogeneic transplantation is associated with a significant risk of potentially life threatening complications due to the effects of chemotherapy and radiation on the body and the risks of serious infection. In addition, patients may develop a condition called Graft versus host disease that arises from an inflammatory reaction of the donor cells against the recipient's normal tissues. The risk of graft versus host disease is somewhat increased in patients who are receiving a transplant from an unrelated donor. One approach to reduce the toxicity of allogeneic transplantation is a strategy call nonmyeloablative or "mini" transplants. In this approach, patients receive a lower dose of chemotherapy in an effort to limit treatment related side effects. Patients undergoing this kind of transplant remain at risk for graft versus host disease particularly if they receive a transplant from an unrelated donor. The purpose of this research study is to examine the ability of a drug called CAMPATH-1H to reduce the risk of graft versus host disease and make transplantation safer. CAMPATH-1H binds to and eliminates cells in the system such as T cells that can cause graft versus host disease (GvHD). As a result, earlier studies have shown that patients who receive CAMPATH-1H with an allogeneic transplant have a lower risk of GvHD. In the present study, we will examine the impact of treatment with CAMPATH-1H as part of an allogeneic transplant on the development of GvHD and infection. In addition, we will study the effects of CAMPATH-1H on the immune system by testing blood samples in the laboratory.
The purpose of this prospective clinical data collection is to document the performance and clinical outcomes of the ExploR® Modular Radial Head. This data collection effort will document the clinical outcomes of the radial head.
