I occasionally get GP's asking me why I passively test all of my clients for ADHD and Autism, which often leads to activer assesssments and then referrals. I respond that in my opinion and experience, if someone has been in the mental health system for over 2 years without resolving their issues, then the odds are very high that we are dealing with a biological problem that is causing poor mental health, rather than a mental health disorder as the primary condition, and the most likley biological cause is ND [being Neurodivergent] (medically an NDD, Neurological Developmental Disorder {as if Autism and ADHD are delays in development rather than different neurology, which can sometimes be advanced}] which are most commonly ADHD and Autism.
My personal professional opinion counts for something, but it isn't anything more than a professional anecdote.
David Eberhard, Eva Billstedt and Christopher Gillberg released the paper "Neurodevelopmental disorders and comorbidity in young adults attending a psychiatric outpatient clinic" in July 2022. In this paper, they report that all first time attenders at a young adult psychiatry (age 18 to 25) clinic were screened for Autism and ADHD along with the more usual psychiatric conditions.
Keep in mind that the general population has around 5% ADHD and 2-3% Autism, with an expected overlap of 35-85% between the two [some populations are far higher, such as refugee camps which can hit 40% ADHD].
Eberhard et al, found that "Almost two thirds (63%) of the study group met criteria for ADHD or ASD" and that most of the patients (especially female presenting) had not been diagnosed in childhood.
I guess that shifts my professional opinion into something backed by another vector of study - it's almost smelling like science now.
