Just as the title asks I’ve noticed a very sharp increase in people just straight up not comprehending what they’re reading.
They’ll read it and despite all the information being there, if it’s even slightly out of line from the most straightforward sentence structure, they act like it’s complete gibberish or indecipherable.
Has anyone else noticed this? Because honestly it’s making me lose my fucking mind.
Rampant untreated adult-onset ADHD
I don’t think there is such thing as adult-onset ADHD, people can (and often do) discover it later in life, but they have signs of it all throughout their life.
ADHD symptoms suddenly appearing in adulthood are likely symptoms of another issue, most likely mental and/or neurological disorders, such as depression, traumatic brain injury, MS, etc.
ADHD is present all your life. You can’t not have it, then just acquire it. That said, there are quite a few disorders that can be acquired that have similar symptoms.
Well, technically it’s a disorder which can emerge from any number of different causes. Yes, generally ADHD emerges as a developmental issue, but you could arrive at the same physiology through sufficiently specific neurodegeneration or brain trauma and these things would still be diagnosable as ADHD and even effectively treated using ADHD medication.
Saying that might seem like a stretch, but consider the fact that we can consistently visually identify an ADHD prefrontal cortex in brain scans. When reduced volume is observed, it’s even possible to predict to some extent the symptom severity by how much appears to be missing. For several decades of research, the precursor to the modern ADHD diagnosis was even called “minimal brain damage”.
All of the scientific literature that I have ever read on the topic has strongly stated that there is no way to identify ADHD from brain scans or anything like that.
Also, no, any situation you describe wouldn’t be diagnosable as ADHD, one of the requirements of an ADHD diagnosis is that the condition is present from birth.
What you’re describing sounds like what I wrote above, and it’s not ADHD, it’s traumatic brain injury, or MS, or what have you. And they may or may not be treatable in the same way as ADHD, because the symptom’s cause is likely totally different.
Identify =/= diagnose. You also cannot diagnose ADHD with a genetic test, despite genetics being a strong indicator. I alluded to this by following up with “when reduced volume is observed”, but you’re right in saying that it would have been less misleading to state directly that brain scans are never in and of themselves used to diagnose ADHD.
If we’re talking DSM-5, the criteria is actually that the onset of symptoms occur by 12 years of age. Even if you take the DSM-5 as gospel, it’s entirely possible for a 6 year old to experience a traumatic brain injury to the prefrontal cortex, heal from the initial trauma, continue to demonstrate symptoms, then receive an ADHD diagnosis. You might call that a misdiagnosis, but I don’t see much of a difference if the symptoms and treatment are the same. There are also recent studies which explore the development of ADHD secondary to traumatic brain injury in adults which I think could eventually warrant further broadening the diagnostic criteria.
Would you share some academic sources for brain scanning being able to identify or diagnose ADHD, please?
I’m posting a source for my original claim: “we can consistently visually identify an ADHD prefrontal cortex in brain scans”. This is not the same as a source which proves that brain scanning is able to identify/diagnose ADHD itself. The order of operations is reversed, because the only way to diagnose a disorder like ADHD is through observation of symptoms, not physiology.
To be clear: what I claim is that you can compare brain imaging of an average individual (oxymoron notwithstanding) diagnosed with ADHD against the brain imaging of an average individual not diagnosed with ADHD and visually see a difference.
Source for this claim, w/ attention to table 4: https://sci-hub.se/https://doi.org/10.1016/j.biopsych.2006.06.011
I don’t really think this is showing what you think it is - table 4 references four studies which finds a significant difference in volume of the prefrontal lobe… but table 3 references three studies which do not find a significant difference. The sample sizes are very low in almost all of the studies being fewer than 20 people with ADHD. And even those studies which show that statistically significant difference have a relatively high probability that the results are explained by chance (heterogenity p)
There’s quite a bit of research into this area, but it has all of the classic problems of ADHD studies, having been conducted on predominantly male children. Studies have been conducted on adults with ADHD and tend to find a significantly smaller difference, if any. A lot of the studies I read about stated explicitly that any difference, when compensated for gender, age, race, etc. is so slight as to be completely unnoticeable unless the imaging was conducted by expert specialists who were specifically looking for it.
I think many people can show similar symptoms as in ADHD because of our current lifestyle.
More and more people have short attention spans, trouble concentrating, trouble directing their focus, procrastination, etc. because our brains aren’t made for how we currently live.
