Hi there ~
I am an allopathic doctor and believe that the medications used are effective. You do not mention the kinds of medicines that are being given to your son, however I can guarantee you that your son will improve with the treatment. OCD
are both disorders that are treatable. I believe that you will find this to be true when you visit with discuss and then have your son be started on both medications and therapy by a qualified psychiatrist
and a counselor. I am not sure what you mean when you say "very dull and weak emotionally" but a lot of the treatment has to do with his being on medications and therapy.
I hope this helped. Take care and have a lovely day !
