Active clinical trials for "Obsessive-Compulsive Disorder"

The goal of this project is to improve access to effective treatments for obsessive compulsive disorder (OCD) through the use of web-based cognitive behavioral therapy (CBT) treatment. There intervention involves both a computer program (BT Steps) and human interaction via telephone. The investigators will test the efficacy and feasibility of computer therapy alone (n=35), computer plus a non-therapist coach (n=35), and computer plus a CBT therapist coach (n=35

Roughly one-third of patients with obsessive-compulsive disorder (OCD) do not experience significant clinical benefit from first-line interventions such as pharmacotherapy with selective serotonin reuptake inhibitors (SSRI) or cognitive behavioral therapy (CBT). Furthermore, OCD patients typically experience the full treatment benefits of first-line interventions only after a time-lag of two to three months. Inadequate symptom relief and delay of symptom relief from first-line treatments are sources of substantial morbidity and decreased quality of life in OCD patients. Converging lines of evidence from neuroimaging, genetic and pharmacological studies support the importance of glutamate abnormalities in the pathogenesis of OCD. The investigators are conducting an open, uncontrolled study of ketamine in treatment-refractory OCD. Ketamine is a potent antagonist of the N-methyl-D-aspartate (NMDA) receptor and has been demonstrated to have rapid anti-depressant effects in patients with Major Depressive Disorder. The investigators have additionally provided evidence for rapid improvement of comorbid OCD and trichotillomania after ketamine infusion in a depressed woman. Failure of symptom relief and delay of symptom relief from first-line treatments are a source of substantial morbidity and decreased quality of life in OCD patients. Ketamine represents the possibility to provide rapid symptom relief to OCD patients and may provide the mechanism for future drug development to treat OCD more rapidly and effectively.

This study will determine the effectiveness of adding motivational interviewing to cognitive behavioral therapy, consisting of exposure and ritual prevention, in improving treatment outcomes in people with obsessive-compulsive disorder.

Objectives: To evaluate tolerability and efficacy of escitalopram treatment in high dose than 20-50 mg/d in out-patients with OCD Type of the study: Open label, prospective study. Number of patients: 100 patients with OCD Duration of the study: 18-weeks of active treatment, 8-visits: Dose titration: One week of 10mg Four weeks of 20mg After 4 weeks of 20mg treatment- if partial/no response, according to YBOCS score and clinical judgment, dose increase of up to 50mg depending on response, adverse events, patient preference and judgment of the clinician 12 weeks follow up on high dose. Total of 18 weeks of follow-up.

This study will examine the effectiveness of riluzole for treating Obsessive-Compulsive Disorder in Youth, Including those with Autism Spectrum Disorders.

Obsessive-compulsive disorder is a disabling and frequent disorder. In some patients, the medical treatment is ineffective. The pathophysiology of this disease is still unknown. Some data suggest that basal ganglia dysfunction could participate in the occurrence of OCD. The aim of this study is to evaluate the efficacy of subthalamic nucleus high-frequency stimulation in patients with severe OCD.

This study will evaluate the effectiveness of two cognitive behavioral therapies (CBTs) in treating obsessive compulsive disorder (OCD) in patients who are taking medication but still have residual symptoms.

Bacteria carry substances on their surface called antigens. When antigens come into contact with the right kinds of cells in the body an immune reaction is caused. This reaction is often the symptoms of sickness that a patient feels. In order for the body to fight off the attack of antigens, it creates substances called antibodies. Antibodies counter the action of antigens and make the bacteria harmless. However, the immune system must learn how to make the right antibodies for the right antigens. Sometimes the body creates antibodies that confuse normal tissues as foreign and attack them. This is called an autoimmune reaction and sometimes occurs when the body is exposed to certain bacteria. One bacteria known for causing autoimmune reactions is Group A beta-hemolytic Streptococcus (GABHS). This bacteria often causes throat infections commonly known as "strep throat". Some researchers believe that the autoimmune reaction associated with strep throat infections may cause neuropsychiatric disorders, like obsessive-compulsive disorder and/or tic disorder in children. As a result, each time a child with one of these disorders experiences an infection with GABHS his/her symptoms can reoccur or worsen. Researchers believe that by giving patients a certain antibiotic, they can prevent GABHS infection and thus prevent the return of symptoms. This study is designed to test the effectiveness of the antibiotic Amoxicillin for the treatment of Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS). Patients will receive Amoxicillin for six weeks and placebos "inactive sugar pills" for six weeks in order to see if the medication is truly working. Effectiveness of the treatment will be based on the presence or absence of symptoms. If at the end of the study Amoxicillin is proven to be effective treatment for PANDAS patients may be offered the opportunity to continue taking the medication for an additional six months.

This preliminary study aims to examine the outcomes from a therapist guided, parent-led, CBT treatment for preadolescent children (aged 5 to 12 years old) with OCD. Specifically, this study aims to: Examine outcomes for children who receive the therapist guided, parent-led, CBT treatment for preadolescent children with OCD. Examine parents' experiences and views about the acceptability of the treatment approach.

This study is investigating whether combining noninvasive brain stimulation with behavior therapy can help to improve outcomes for obsessive-compulsive disorder (OCD). Exposure and response prevention (ERP) -- a specific type of behavior therapy -- is a first line treatment for OCD. This study will test whether a form of noninvasive brain stimulation called transcranial direct current stimulation (tDCS), can help ERP work better.
