Clinical trials

The goal of this clinical trial is to evaluate whether computer-based brain training can help adults with post-traumatic stress disorder (PTSD). Individuals with PTSD often experience difficulties with memory, attention, concentration, and problem-solving, which can significantly affect their daily lives, work performance, and overall quality of life. These cognitive challenges can hinder trauma recovery and reduce the effectiveness of standard PTSD treatments. The main questions this study seeks to address are: Does specialized brain training improve PTSD symptoms compared to regular computer games? Does brain training enhance cognitive functions such as memory, attention, processing speed, and executive functioning? Does brain training improve quality of life and daily functioning? Do participants' self-efficacy and perceived social support influence treatment outcomes? Researchers will compare two approaches: a specialized cognitive training program (HAPPYneuron Pro) with strategy teachings and quality-of-life discussions, versus engaging computer games with quality-of-life discussions, to determine which is more effective for people with PTSD. Study Design Participants will be randomly assigned to one of two groups for an 8-week program: Cognitive remediation training group: Complete computerized cognitive exercises and strategy teachings specifically designed to strengthen memory, attention, and executive functions, combined with quality-of-life discussions. Control group: Complete engaging computer games combined with quality-of-life discussions. Schedule Both groups will follow the same schedule: One online session per week, in small and consistent groups of 4-8 participants. Each 60-minute session consists of 30 minutes of computer activities followed by 45 minutes of group discussion. One at-home individual homework exercise per week (30 minutes at home). Total time commitment: 1h45 per week for 8 weeks. Assessments All participants will complete three comprehensive assessment sessions: before treatment, immediately after the 8-week program, and 3 months later. Assessments include neuropsychological testing and questionnaires on PTSD symptoms, depression, anxiety, quality of life, satisfaction with life, social support, cognitive failures, and self-efficacy. Significance This research evaluates a new, accessible and remotely deliverable approach for PTSD treatment. Current evidence-based treatments often do not directly target the cognitive impairments experienced by many individuals with PTSD. Compensation Participants will receive $35 for each completed assessment (maximum $105). Control group participants will gain access to the cognitive remediation training program after completing their participation.

The goal of this clinical trial is to compare the effectiveness of CoPs therapy with or without the therapeutic component of biofeedback in treating tics in Tourette Syndrome with emerging young adults. Hypotheses: 1. The CoPs+Biofeedback treatment will improve the severity of tics (YGTSS) and the Clinical Global Impression, surpassing the clinical significance threshold of CoPs treatment alone. 2. We expect that the identified variables (psychosocial, neurocognitive, biological) will predict the improvement of tics. Researchers will compare if the biofeedback treatment will improve the severity of tics. * In the pre-test, participants will undergo two interviews, each lasting 3 hours. These interviews will assess (through a battery of tests) the severity of tics as well as the psychosocial, biological, and neurocognitive aspects of functioning. A general assessment of intelligence and executive functions will also be conducted. * They will next attend 10 to 12 therapy sessions, with or without biofeedback. (The biofeedback component is explained in more detail in the ''Study Design'' section). * The post-test follow-ups consist of two evaluations: one 3 months after the end of the treatment and the other 6 months after. The evaluation will be done using the same battery of tests as during the pre-test interview.
