Filter by:Deep brain stimulation (DBS) is an effective treatment for people suffering from severe obsessive-compulsive disorder (OCD) whose symptoms have failed to improve after years and multiple methods of intervention. An effective DBS target for OCD is the anterior limb of the internal capsule (ALIC) brain region. On average 60% of all OCD patients have a clinically significant response to ALIC DBS. However, ALIC DBS may become even more effective with the ability to predict which specific ALIC connections in the brain need to be stimulated for each individual OCD patient. This study therefore investigates personalized stimulation to the ALIC that allows for precise modulation of brain circuits associated with individual OCD symptoms. The study aims to specify the ideal anatomical target for ALIC DBS for maximum therapeutic benefit in each patient.
Psychiatric Comorbidity and quality of life in patients with Obsessive Compulsive Disorder(case control study )
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.
To test the feasibility of implementing digitally enhanced psychotherapy and research in a community child and adolescent mental health center including the acceptability of the digital technology to patients, parents and therapists. To use passively collected physiological data and actively collected clinical and biochemical data from the patient and parents to detect and predict episodes of obsessive-compulsive disorder (OCD) -related episodes in children and accommodating behaviour in parents.
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.
Internet-based psychotherapy for children and adolescents with obsessive-compulsive symptoms and an age of 6 to 18 years. Sessions are verified with teleconferencing with an psychotherapist, children and their parents. The psychotherapy is supported by an App and a wristband to obtain psychophysiological data. The investigators have already successfully performed a feasibility study.The goal of the current proposal is to develop an internet and smart phone delivered CBT (iCBT) for the treatment of pediatric OCD on the bases of the feasibility study. Internal testing on iCBT therapy package and developmental workchanges has been done. The investigators are now evaluating effectiveness in an RCT.
Obsessive-compulsive disorder (OCD) is a psychiatric syndrome characterized by unwanted and repetitive thoughts and repeated ritualistic compulsions aimed to decrease the distress. Symptoms can cause severe distress and functional impairment. OCD affects 2-3% of the population and is ranked within the ten leading neuropsychiatric causes of disability. Dysfunction of the cortico-striatal-thalamo-cortical circuitry (CSTC) has been implicated in OCD, including altered brain activation and connectivity. A complex dysregulation of glutamatergic signaling within the cortico-striatal circuitry has been proposed in OCD. Data obtained by several studies are suggesting of a reduced glutamatergic concentrations in the anterior cingulate cortex, combined with overactivity of glutamatergic signaling in the striatum and orbitofrontal cortex. A growing number of RCTs have assessed the utility of different glutamate-modulating drugs as an augmentation or monotherapy in OCD, including refractory patients. However, there are relevant variations in between studies in terms of treatment-resistance, comorbidity, age and gender of the patients. At the present time four RCTs are available on the efficacy of memantine as an augmentation medication for refractory OCD patients. Investigators intend to conduce a double-blind, randomized, parallel group, placebo-controlled, monocentric trial to assess the efficacy and safety of memantine, a low-to-moderate affinity noncompetitive NMDAR antagonist that is currently approved for the treatment of Alzheimer disease, as an augmentative agent to a SSRI in treatment of patients affected by severe refractory OCD. Study design consists of four distinct periods (52 weeks) including memantine titration, neuropsychological assessment and follow-up.
The primary objective of the proposed study is to evaluate the safety and efficacy of Epidiolex (cannabidiol) in adults with obsessive compulsive and related disorders (OCRDs). Subjects will be treated in an open-label fashion with Epidiolex for two weeks.
The present study aims to explore the efficacy and safety of DBS targeted the combination of the anterior limb of internal capsule and nucleus accumbens (ALIC/NAcc-DBS) to refractory OCD, based on multicenter, randomized, double-blinded, sham-stimulation controlled design, that could help to obtain stronger evidence of the efficacy of multiple targets.
To verify that sertraline combined with fluvoxamine is superior to sertraline combined with aripiprazole
