Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much in this regard. You should take your son to a psychiatrist if you are sure about the symptoms. Distinguishing between Schizophrenia and Bi-polar disorder is a typical task and a trained psychiatrist or clinical psychologist can do it. There are so many symptoms which are common but uncommon. You can search internet to find the symptoms and you can do some diagnosis. In any case, you need expert assessment and advice. You might need psychological counseling and or psychotherapy.
