HIPPA only applies to an individual who, or a company that, regularly works with patients and stores medical information. These places include hospitals, clinics, nursing homes, pharmacies and individual doctors, as well as healthcare provider. Since you did not mention any of the above, Iassume that you do not work as such a place. Therefore HIPPA does not apply. Additionally, you have aready mentioned that your son does suffer from schizophrenia and it;s common knoweldge, so you can't even sue for defamation.
