I don't really know the situation in the US. Here in Germany it is for sure rigorous. I had three appointments and lots of questionnaires to fill out at home that were designed to exclude all kind of conditions. And with a diagnosis I was still far away from getting a prescription, that is whole other hurdle. As for the US, well the CDC says in the section for conditions that must be met: > The symptoms are not better explained by another mental disorder (such as a mood disorder, anxiety disorder, dissociative disorder, or a personality disorder). The symptoms do not happen only during the course of schizophrenia or another psychotic disorder. https://www.cdc.gov/adhd/diagnosis/index.html https://www.cdc.gov/adhd/diagnosis/index.html So it is pretty clear on that.
