The first time, I was not ready with the citation at hand, but was hoping for a discussion or context. I then forwarded him the citation (it was published in Brain, impact factor hovers around 10 and top 20 journal in neuroscience). I have since found articles with similar findings from a range of journals, including Lancet Psychiatry, JAMA. I specifically requested sources to start reading, but he just told me there were thousands and reference Hypocrites descriptions of ADHA being similar to clinical descriptions today.
So now, I am back on the market for someone to help with a full and detailed assessment that is capable and willing to discuss and justify their decisions.
