Obsessive-Compulsive Behavior

The project is an interventional trial that compares digital training programs with varying levels of therapeutic contact. All participating children and adolescents will receive a digital training program following a thorough online evaluation. Additionally, parents are invited to participate in an online, supportive parenting program designed to complement the digital treatment.

The goal of this clinical trial is to test transcranial magnetic stimulation (TMS) for improving the outcomes of Exposure with Response Prevention (ERP) in youth and young adults with Obsessive-Compulsive Disorder (OCD). Researchers will compare two groups: ERP with active ("real") TMS vs. ERP with sham ("fake") TMS. The first phase of this study found that active TMS+ERP normalized functioning in brain circuits that contribute to compulsive behavior. This second phase will test whether TMS-induced brain changes lead to improvements in OCD symptom severity. Participants will: * Complete clinical interviews, questionnaires, and computerized tasks * Complete two MRIs (brain scans) * Receive daily TMS followed by ERP for two weeks (10 sessions)

The goal of this investigational study is to evaluate if the treatment using EXOMIND(BTL-699-2) device is able to improve severity of obsessive and compulsive symptoms in adults (aged 22 and older). The main question it aims to answer is: Does the treatment using EXOMIND (BTL-699-2) device is able safely and efficiently reduce the severity of obsessive and compulsive behaviors? Participants will be asked to: * Complete six treatment visits (twelve treatment sessions) * Complete The Yale-Brown Obsessive-Compulsive Severity Scale Second Edition Self Report Version (Y-BOCS-II SR) * Complete Short UPPS-P Impulsive Behaviour Scale (SUPPS-P) * Compete The Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) * Compete The Patient Health Questionnaire-9 (PHQ-9) * Compete Columbia Suicide Severity Rating Scale -screen version(CSSRS) * Complete Trigger Recall Experience Questionnaire (only for participants who agree to participate in trigger recall procedure during the treatment sessions) * Compete The Therapy Comfort Questionnaire * Compete The Subject Satisfaction Questionnaire

This observational, cross-sectional case-control study evaluates obsessive-compulsive symptoms among adults with substance use disorder compared with a demographically similar control group without substance use disorder. Patients aged 18-50 years attending the addiction management inpatient and outpatient services at Assiut University Hospital, and healthy controls recruited from relatives, friends, and hospital staff, will complete structured clinical interviews, the Yale-Brown Obsessive-Compulsive Scale, and other standardized scales for psychiatric symptoms, cognition, and quality of life. The main objective is to estimate the prevalence and severity of obsessive-compulsive symptoms in substance use disorder and examine their associations with sociodemographic and clinical factors, addiction severity, and quality of life in the recovery stage.
