Obsessive-compulsive disorder is characterized by the presence of obsessions and/or compulsions. Obsessions are persistent, repetitive images, impulses, or urges that are intrusive and unwanted and are usually accompanied by anxiety. Compulsions are repetitive mental behaviors or acts that a person feels compelled to perform in response to an obsession, according to rigid rules or to achieve a sense of perfection. Children may have difficulty identifying or describing obsessions, but most adults can recognize the presence of both obsessions and compulsions. Obsessive-compulsive disorder usually leads to multiple psychological problems that affect the person's life. Considering the high percentage of people with obsessive-compulsive disorder in society and the psychological problems reported in these individuals, and since current treatments for people with obsessive-compulsive disorder show many shortcomings and are unable to completely treat this disorder, and also because no study has examined the effectiveness of transcranial direct electrical stimulation of the brain on the integration of thought and action in adolescents with obsessive-compulsive disorder, the aim of this study was to examine the effectiveness of transcranial Direct Current Stimulation on the integration of thought-Action Fusion in adolescents with obsessive-compulsive disorder.  Methods: In this study, which was conducted as a quasi-experimental study with pre-test and post-test with a control group, 30 eligible volunteers aged 12 to 18 years were selected from among adolescents with obsessive-compulsive disorder in Yazd and entered the study. 15 of them were randomly assigned to the intervention group and 15 to the control group. The scores of the thought-action fusion variable were compared using the thought-action fusion scale (Shaffran et al., 1996) at two time points before and after electrical stimulation treatment. Data analysis was performed using analysis of covariance. The significance level of the tests was 0.05. Results:   Data analysis showed that the thought-action fusion test score in patients with obsessive-compulsive disorder in the intervention group and after receiving treatment was significantly reduced compared to the control group (P=0.001). Conclusion: In explaining the results of the study, it can be said that the transcranial brain stimulation method using direct electrical current has been used by doctors and neuroscientists to treat mental and neurological disorders. Transcranial direct electrical stimulation of the brain causes more or less firing of brain cells by changing the excitability of neurons and shifting the membrane potential of surface neurons in the direction of depolarization or hyperpolarization. Transcranial direct current stimulation of the brain is used to alter the excitability of the cortex in targeted areas, increasing or decreasing brain function. transcranial Direct Current Stimulation is used to increase the excitability of the cortex and cathodal current is used to decrease it. In this method, electrodes are placed on the patient's head to pass a continuous, gentle electric current through it. Essentially, transcranial direct current stimulation of the brain increases excitability in targeted areas of the brain and leads to changes in cognitive and behavioral function in individuals. The current is supplied by a battery-powered direct current generator. Through this current, long-term changes in the polarity of the cerebral cortex occur. These changes are caused by depolarization and hyperpolarization of neurons and the effect on nerve receptors. In general, transcranial direct electrical stimulation of the brain is a neurotherapeutic technique that involves introducing a weak direct current into areas of the cerebral cortex. This current aims to facilitate spontaneous neural activity. By stimulating specific areas of the cortex, transcranial direct current stimulation of the brain can potentially improve or reduce brain functions.   تحریک مستقیم الکتریکی فراجمجمه ای مغز, آمیختگی فکر و عمل, اختلال وسواس فکری-اجباری transcranial Direct Current Stimulation, thought-Action Fusion, obsessive-compulsive disorder 0 0 http://jdisabilstud.org/browse.php?a_code=A-11-3879-1&slc_lang=fa&sid=1 mohadeseh Mokarrami محدثه مکرمی mohadeseh.m72@gmail.com 100319475328460067145 100319475328460067145 No science and arts university دانشگاه علم و هنر یزد mohsen saeidmanesh محسن سعیدمنش m.saeidmanesh@yahoo.com 100319475328460067146 100319475328460067146 Yes science and arts university دانشگاه علم و هنر یزد
