OCD


e. relationships with others. (Internet 2) People with OCD show a range of insights into the senselessness of their obsessions. Often, especially when they are not having an obsession, they can recognize that their obsession and compulsions are unrealistic. At other times, they may be unsure about their fears and even believe them to be valid. (Internet 3) .
             Most people with OCD struggle to get rid of their unwanted obsessive thoughts and to prevent themselves from engaging in compulsive behaviors. Many are able to keep their obsessive-compulsive symptoms under control at work and at school. But over months and years, their resistance may weaken and when that happens, OCD may have become so severe that time consuming rituals take over the individual's life, making it almost impossible to function normally outside the home, Most suffers of OCD hide their disorders rather than seek help. An unfortunate consequence of this secrecy is that people with OCD do not receive help until years after the onset of the disease. By that time, they may have learnt to work their lives and the lives of their family members, around the rituals. (Internet 3) .
             What Causes OCD .
             The old believe that OCD was the result of life experience has been weakened as before it was perceived that growing evidence that biological factors are a primary contributor to the disorder. OCD is no longer attributed only to attitudes the patient learned in a childhood e.g. an over emphasis on cleanliness, or a belief that certain thoughts are dangerous or unacceptable. The search for causes of OCD now focuses on the interaction of neuro-biological factors and environmental influences, as well as cognitive processes. (Internet 3) .
             In an effort to identify specific biological factors that may be important on the onset or persistence of OCD, investigators from the National Institute of Mental Health (NIMH) have used a device called the Positron Emission Tomography (PET) scanner to study the brains of patients with OCD.
