Declaration This is to certify the research work embodied in this thesis entitled (Obsessive compulsive disorder) has been written by both of us and under the supervision of Dr. Narges kablan Safaa Omar Abbas Heba Farag Zainoba 2 Abstract Obsessive compulsive disorder (OCD), one of the anxiety disorders, is a potentially disabling condition that can persist throughout a person's life. The individual who suffers from OCD becomes trapped in a pattern of repetitive thoughts and fears (obsessions) and behaviors (compulsions) that are senseless and distressing but extremely difficult to overcome. OCD occurs in a spectrum from mild to severe, but if severe and left untreated, can destroy a person's capacity to function at work, at school or even in the home. The causes of the OCD are still unknown, but there are factors that may increase the risk of developing or triggering the disorder which include:(Neurobiological, behavioral, cognitive, environmental, infection or genetic factors) The most effective treatments for OCD are Cognitive Behavior Therapy (CBT) and/or medication. More specifically, the most effective treatments are a type of CBT called Exposure and Response Prevention (ERP), and/or a class of medications called serotonin reuptake inhibitors (SSRIs). In severe cases of OCD and in individuals who do not respond to medical and behavioral therapy, more drastic options might be useful such as brain surgeries. OCD is a chronic disease that requires long-term treatment with frequent follow up and a regular behavioral therapy. OCD needs more attention and awareness especially in the Arab world, an aim that is intended to be reached in this study by spotting the light on the concept, signs and symptoms and the treatment of this disease. 3 Table of contents Abstract ..........................................................................................................................................3 seLo t o tsiL
