There are some cool studies done where people with a without ADHD are tasked to forage berries. The people with ADHD do better and adhere to foraging patterns which existing theories suggest would be more optimal.
A lot of the studies like that indicate the individual with the condition might benefit more from ADHD than the group they’re in, but I’m not sure that studies have explored group benefits very much.
There’s an often cited paper in which nomadic men who carry a certain ADHD-related allele (DRD4-7R, a dopamine reception variant with ADHD traits and novelty seeking) tend to have better nutritional status. I can’t recall much about it or how high quality it is.
2. Assuming it really is: Why would this make it unlikely to be encoded on a single gene? As a layman, the only condition I'm aware of with this "downside but also upside" quality is sickle cell anaemia (downside is anaemia, upside is increased resistance to malaria), which is decided by a single nucleotide change on chromosome 11.
- Clinical Interview
- Wechsler Adult Intelligence Scale – Fourth Edition (WAIS-IV)
- Wechsler Memory Scale – Fourth Edition (WMS-IV)
- Conners Continuous Performance Test – Third Edition (CPT-3)
- Delis-Kaplan Executive Functioning System, selected subtests
- Wisconsin Card Sorting Test (WCST)
Are you familiar with any of those? I did some research after receiving my report and apparently the combination of tests listed above are well-respected, about as good as it gets. I’m curious what your take is.
The subjective part of the assessment was actually the clinician making sense of the data. My cognitive assessment (IQ and its subtypes) scored fairly high, I averaged something like 115 (84th percentile). But my memory assessment scores (audio/visual memory/working memory, immediate/delayed memory) tanked tremendously, I averaged around 90 (30th percentile).
My positive diagnosis was based on the variability of scores and the clear cognition-memory gap. The results made sense, aligned with my experience in life (I fell asleep in almost every lecture in college, sustaining attention while taking notes was a heavy audio-visual working memory exercise for me).
I personally haven’t adopted any of this as my identity but it opened a door to do some metacognition and reflect on how I interface with the world. Also the stimulant medication didn’t magically fix everything, sometimes the hyper focus is worse, but there was one HUGE benefit that I didn’t realize I was missing - emotional regulation. I’m a heavy ruminator and pretty much suffered in silence most of my life, my inner dialog is much more organized and calm, and I can comb through my thoughts easier now.
P.S. I cannot recommend enough - check out “HealthyGamerGG” on YouTube. He does some deep dives on ADHD and other diagnoses. Classically trained psychiatrist with something like 5 years of training as a Buddhist monk. Very insightful guy who’s both data-driven and spiritual, helping a lot of people.
We don't really know what mental disorders are and so we don't have objective diagnostic tests for them. [1]
We just have treatments that sometimes work for some people (and with the replication crisis[2] that sometimes is probably a lower value than expected).
