Active clinical trials for "Obsessive-Compulsive Disorder"

Obsessive Compulsive Disorder results in high social impact, affecting quality of life and tending to a chronic course. A considerable proportion of patients, up tp 60%, remain with symptoms even thought treatment is administrated. Therefore, new therapeutic interventions are highly necessary. In this context, repetitive transcranial magnetic stimulation has been used for several psychiatric conditions, including OCD treatment. Moreover, many approaches of neuromodulation seem to reach a better result when used a priming stimulation. In an attemp to optimize particularities of the thecnique applied, this study aims to assess if a priming stimulation with rTMS might impact in a better outcome when compared with rTMS without previous stimulation.

The study will examine whether inhibition of the pre-supplementary motor area (pSMA) using transcranial magnetic stimulation (TMS) normalizes activity in pSMA-connected circuits, improves response inhibition, and reduces compulsions in adolescents with OCD.

Patients with obsessive-compulsive disorder (OCD) experience a wide array of different types of obsessions and compulsions. However, current treatments for OCD employ a "one size fits all" approach and are used for all patients regardless of symptom type. In this project, the investigators propose to investigate whether a novel method of transcranial magnetic stimulation specifically reduces contamination/washing symptoms - one of the most common types of OCD.

The purpose of this study is to provide participants diagnosed with obsessive compulsive disorder (OCD) and completed one of the active study protocols at the Rodriguez Lab, with open/aftercare treatment.

This study investigates whether the commonly used and well-tolerated inhaled anesthetic nitrous oxide can rapidly improve symptoms of OCD.

Obsessive-compulsive disorders are very damaging illnesses; they can already appear in childhood and adolescence and become extremely chronic. With an average prevalence from 1-3%, they are among the most common psychiatric disorders in children and adolescents. 40% of diagnosed children and young adults display persistent and increasingly chronic symptoms and O-C disorders are highly complex syndromes with broadly varying manifestations. They arise from obsessive thoughts (ideas/thoughts or impulses, often senseless or tortured, that impose themselves or intrude) and obsessive behavior (ritualized patterns that must be frequently repeated).

The primary objective of this study is to determine the safety and efficacy of ultrasound as a treatment for Obsessive Compulsive disorder.

The purpose of the study is to evaluate the long term safety and tolerability of troriluzole as adjunctive therapy in subjects with obsessive compulsive disorder (OCD).

The primary objective for this study is to evaluate whether Rituximab as compared to placebo is a clinically effective treatment for a subgroup of patients suffering from psychosis and/or obsessive-compulsive disorder (OCD) or -behavior (OCB) where there is an indication of immune system involvement. The secondary objectives of this study are To assess whether Rituximab treatment (with the doses and timing described below) as compared to placebo is associated with amelioration in psychiatric symptomatology To assess whether Rituximab treatment as compared to placebo is associated with improvement in executive functions To assess whether Rituximab treatment as compared to placebo is associated with amelioration in neurological symptoms To evaluate the longevity of psychiatric, neurological and executive improvements associated with Rituximab treatment for up to 16 months after the first infusion (i.e. 12 months after the last infusion) To evaluate whether Rituximab treatment as described is safe for these patients. The exploratory objectives of this study are To assess changes in blood and cerebrospinal fluid (CSF) markers for immune activity associated with Rituximab treatment compared to placebo To assess statistical associations between biological markers in blood or CSF and clinical response To describe changes in somatic symptoms associated with treatment with Rituximab vs placebo for patients with initial symptoms in the questionnaires To describe changes on MR and EEG associated with treatment with Rituximab vs placebo for patients with initial pathology in these examination To study immune mechanisms coupled with psychiatric symptoms, possibly identifying novel biomarkers with potential for subtyping encephalopathies with immune engagement, using biobank cells, blood and CSF samples collected from the participants.
