Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. OCD is Obsessive behavior. Such obsessive behaviors are to be controlled by the patient himself. Even if some others try, result seldom are positive. Apprehend your grandson of the situation and once he become aware of his obsessive behavior, he shall try to change. At least he learns to tackle the behavior. That attitude is the first step. A good psychological counselor should help in achieving this. The Cognitive Behavior Therapy (a form of psychotherapy) works wonders. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
