Active clinical trials for "Obsessive-Compulsive Disorder"

The purpose of this study is to determine whether individuals with obsessive compulsive disorder who will take a preparation of the amino acid glycine in addition to their current treatment, may experience improvement in their symptoms.

Obsessive-compulsive disorder (OCD) is a common psychiatric illness that affects up to 2-3% of the population. People with OCD experience anxiety-provoking, intrusive thoughts, known as obsessions, and feel compelled to perform repetitive behaviors, or compulsions. The only medications proven effective for OCD are serotonin reuptake inhibitors (SRIs), but even with SRI treatment, most patients continue to experience significant OCD symptoms, impaired functioning, and diminished quality of life. Recent evidence suggest that a different neurotransmitter, glutamate, may contribute to the symptoms in OCD. Medications that target glutamate hold promise for ameliorating symptoms for those patients continuing to suffer from OCD. In this study the investigators are recruiting patients to receive the drug memantine, which is thought to modulate the neurotransmitter glutamate, added to whatever other OCD medications they are taking. Open label memantine will be titrated in 5mg increments weekly to target dose of 10mg po bid for up to 6 weeks. Memantine will be continued to 12 weeks in those with treatment response,13 either previous response to ketamine (≥ 35% Y-BOCS reduction 1 week after IV ketamine) or current response to memantine (≥ 35% Y-BOCS reduction from pre- to post-6 weeks of memantine).

Pediatric obsessive-compulsive disorder (OCD) is a chronic and often disabling illness with an estimated lifetime prevalence of 1 to 3%. Pediatric OCD is associated with significant social, educational, and familial impairment, as well as comorbid emotional and behavioral disturbances that serve to complicate the prognosis of the illness and treatment outcome. While limited open treatment trials and one controlled trial have demonstrated cognitive-behavioral therapy (CBT) to be effective for pediatric OCD, controlled trials are lacking in the literature. There are a number of incremental benefits that an intensive program for OCD may offer. First, existing outpatient interventions typically achieve treatment gains over a 15 to 20 week period. The present program typically lasts between 2 to 4 weeks, and thus may present as a more timely, cost-effective, and efficient means of treatment for some individuals. Second, given that many children and adolescents may not have access to mental health professionals who are trained in empirically grounded interventions for OCD, the present treatment setting allows youth to receive appropriate, state of the art care. Finally, evidence suggests that daily CBT may be particularly effective in treating children who have been refractory to prior treatments (e.g., medication or once per week CBT). Prior to treatment, all consenting families will be randomly assigned to either the treatment condition or a three-week wait-list control condition. Those families randomized to the wait-list condition will receive treatment immediately after the three weeks are completed. The treatment group will be administered all measures immediately before treatment, immediately after treatment, and three months after treatment. The wait-list control condition will be administered all measures upon starting the wait-list period, immediately following the conclusion of the three-week wait-list period, and after the treatment program has finished. The purpose of the current study is to evaluate the efficacy of daily cognitive-behavioral treatment for pediatric OCD.

Cognitive-behavioral therapy (CBT) has proven efficacy for treatment of pediatric obsessive-compulsive disorder (OCD). Yet, CBT does not help all children and those who benefit often remain symptomatic upon treatment completion. Recent clinical trials in adults with other anxiety disorders (acrophobia and social phobia) provided support for using a medication called D-Cycloserine (DCS) to enahnce the outcome of exposure-based psychotherapy. Given this, DCS may augment CBT in youth with OCD, an anxiety disorder that is conceptually similar to acrophobia. With this in mind, the investigators are conducting a randomized, double-blind placebo controlled pilot study of DCS to determine whether it had any short-term clinical benefits on CBT in youth with OCD. Forty children and adolescents (ages 8-17) with a primary diagnosis of OCD will be screened and, should they meet relevant criteria, randomly assigned to one of two treatment conditions: (1) CBT plus DCS, or (2) CBT plus placebo. All patients will receive 10 sessions of CBT A rater will assess participants at 3 separate time points.

The purpose of this study is to determine the effectiveness of St. John's Wort as compared to placebo (an inactive substance) in the treatment of outpatients with obsessive compulsive disorder.

The purpose of this study is to assess the efficacy of Escitalopram in the treatment of obsessive compulsive disorder and to determine the optimal treatment dose.

This study will evaluate the use of Deep Brain Stimulation (DBS) to reduce symptom severity and enhance the quality of life for patients with treatment-resistant obsessive compulsive disorder (OCD).

The purpose of this study is to see if it is effective to treat children with anxiety disorders with fluvoxamine. Fluvoxamine has been successfully used to treat obsessive-compulsive disorder (OCD) in adults and children. Anxiety disorders other than OCD, such as generalized anxiety disorder, social phobia, or separation anxiety, are very common in youth and are not always responsive to behavioral therapies alone. These disorders may respond to fluvoxamine. A child will be evaluated for 3 weeks before he/she is assigned randomly (like tossing a coin) to receive either fluvoxamine or an inactive placebo for 8 weeks. After this double-blind phase (neither the child/parents nor the doctor know which treatment is being given), the child will have the option of continuing treatment during a 4-month open-label extension period (both the child/parents and the doctor know which the child is receiving). A child may be eligible for this study if he/she: Is 6 to 17 years old and has been diagnosed with an anxiety disorder (i.e., generalized anxiety disorder, social phobia, or separation anxiety).

This study used electroencephalogram (EEG) to predict the efficacy of repetitive transcranial magnetic stimulation (rTMS) in patients with obsessive-compulsive disorder.
