> A typical ADHD diagnosis in America is done by a paediatrician or a family doctor in an office visit as brief as 15 minutes.<p>I'm in my 30s, and in the process of receiving a diagnosis after it had been suggested to me my entire life by teachers, colleagues, and friends. I avoided diagnosis and medication mainly because I was skeptical of the safety record of medications -- probably because that's why my parents never sought a diagnosis for me when I was younger.<p>After doing more research the past few years, I learned that ADHD medications are the success story of medical management of psychiatric illness, and they have a strong safety record<p>In any case, for me so far it has involved four (4) 2-hour appointments with a clinician, having trusted colleagues and close friends fill out detailed "external rater" forms in which they rated my executive dysfunction, and (yesterday) a marathon 4-hour long testing session in which I took a sequence of standardized tests under the supervision of a clinician.<p>I know that diagnosis of ADHD in children is a different animal, and even for adults there are clinics that provide a diagnosis and prescription in a half hour or so -- but not everyone with ADHD is diagnosed after a single 30 minute session with a provider. And contrary to another sibling comment, there are fairly robust objective metrics for identifying the hallmark features of ADHD and executive dysfunction.
