Overdiagnosis is not a problem, but misdiagnosis may be as people are driven into the private sector by long waits, and sadly, missed diagnoses remain common —Tamsin Ford

Experts are warning that far from being over-diagnosed, people with ADHD are waiting too long for assessment, support and treatment.

Isn't it strange how we discovered a lot more stars after inventing telescopes?

Obviously there was an unrelated increase in stars born at that exact time.

[–] Railcar8095@lemmy.world 33 points 1 week ago (1 children)

To try to explain the increase of stars in the universe without it's correlation with vaccine rates is just disingenuous. \s

Everyone knows that if the nebula takes paracetamol during pregnancy it increases the chance of K-type star creation.

This is actually the most apt analogy for the whole "sudden increase in diagnosis" bullshit line that anti-vaxxers and anti-science people continually vomit out.

My cousin was diagnosed by a brain scan. She signed up to be part of a clinical trial for something else, got kicked out of the trial because her fMRI showed she had ADHD.

So if we can literally scan someone's brain and diagnose them from a picture instead of all these vague "describe your symptom" guessing... why don't we?

[–] Grimy@lemmy.world 22 points 1 week ago (2 children)

It's quite costly to run an fMRI. Not needed if you can get the same results more or less from a questionnaire.

[–] ickplant@lemmy.world 24 points 1 week ago (10 children)

In my professional experience, it can be hard to tell between ADHD symptoms and CPTSD symptoms. The checklist is not a great way to diagnose people. We usually do a lot more assessments, I also use a computerized test to measure reaction time and error commission.

I wish we (therapists) at least had the option to order an MRI or recommend a doctor orders one in difficult cases (I can do the latter but they will just laugh at me).

It's also worth noting that ADHD, as a condition, is mostly a Gordian knot of maladaptations. Built up over childhood (and beyond). While there are a lot of commonalities, you need to do a detailed investigation to pick out what bits are a problem to the individual.

If you're going to go through that process, then you might as well not tie up an MRI machine for no reason.

Drugs can treat the base problem, but don't work well without the follow-up care to repair the behavioural damage.

I spent most of my life undiagnosed, because it used to be believed that only boys could have ADHD. But I knew, and was formally diagnosed as an adult only at the insistence of my partner.

[–] RQG@lemmy.world 11 points 1 week ago (3 children)

Like many adults I just got recently diagnosed in my mid 30s.

For me it was that I can't have adhd because I was good at school and uni. Then I completely fell apart when I entered work.

I had to go through depression and burn out and bore out and more. Eventually someone said I could have adhd and just been able to deal due to high IQ.

Turns out that's what it was. I'm really good at learning new stuff. So school and uni. I really suck at repeating the same shit all day. So work. Welp. Helps to know.

[–] Echolynx@lemmy.zip 2 points 5 days ago

Huh, never conceived of it that way. I was stellar in secondary school, burnt out in university and crashed out in post-grad plans/attempts. Still trying to revisit those, but have to go at a slower pace.

I've felt like my brain just works... slowly. But I also seem to be pretty good at learning/picking up new things, because the novelty is key. That is definitely a helpful way to reframe it!

This thread somehow brought out some of the most misinformed, boomer-brain takes imaginable and comes dangerously close to anti-intellectualism. We can all agree that labels can be reductive and unhelpful, but as someone with a neurological disability, seeing people debate whether a disorder that makes it incredibly hard to enjoy my life is even real or not is fucking horrible.

All of this applies to Autism, as well.

The moral panic of overdiagnosis comes from conservatism's obsession with hypernormalcy. Basically unless your really-really failed to be normal, you're not allowed to stray from it, and even then, it would be good if you were normal, because they like the virtue of normalcy, and also thinking is hard, and also also change is bad.

Yes this explains modern transphobia a lot. Some admitted, that it has to be "all undone", because people stopped trying to be normal first and foremost. This also partly explains gatekeeping in fandoms.

It’s almost as if we’ve gotten better at understanding the condition overall and in nuance.

[–] ageedizzle@piefed.ca 16 points 1 week ago

Serious question: how would we be able to detect if we’ve over diagnosed a mental disorder such as ADHD? What would evidence for that look like?

[–] yeahiknow3@lemmy.dbzer0.com 16 points 1 week ago* (last edited 1 week ago) (17 children)

According to the administration at a school I’m familiar with, at least 50% of the 5th grade class has ADHD.

So, not having ADHD is the disorder.

[–] BlameTheAntifa@lemmy.world 25 points 1 week ago (4 children)

Their source is they made it up. Getting diagnosed is a pain and there is no way 50% of any sizable population has gone through that process, let alone received a diagnosis.

50%?

The national stats are ~1:10 people have it. 50% is a huge anomaly. Something isn’t right.

[–] yeahiknow3@lemmy.dbzer0.com 16 points 1 week ago* (last edited 1 week ago) (18 children)

Yes, what isn’t right is that it’s an upper class private middle school full of wealthy parents with access to psychiatrists who are financially motivated to provide a fashionable diagnosis.

It’s also a way to get extra time (accommodations) on standardized tests (time and a half or even double time) which further widens the success gap between rich and poor students.

Most data suggests it is under diagnosed.

[–] ickplant@lemmy.world 12 points 1 week ago

Especially in women, like by a lot.

[–] Echolynx@lemmy.zip 12 points 1 week ago

It's the left-handedness chart all over again.

[–] elucubra@sopuli.xyz 10 points 1 week ago (2 children)

I was diagnosed in my late 50's. It was a complicated process because there is another mental health co-morbidity that shares some traits.

After going through the more than a year long process, we are working on dialing in the meds.

One of the challenges for diagnosis is that the attention economy is shortening a lot of people's attention span, causing many people to feel that they have ADHD, and diverting resources from diagnosing people who actually have ADHD. Not saying that the issue shouldn't be addressed. The combination of these factors, and the rather long and complicated process of a proper diagnosis is a challenge.

Why is there never any nuance in these discussions? We can both believe that under-diagnosis occurs, and that over-diagnosis occurs. 20% of all pupils in the UK are now classified as so disabled that they require specialised assistance. "SEND" assistance for this can range from free taxi services to and from school (which recently reached £1.2 billion), to support payments, to special assistants in school. The number of ECHP students (those with the highest needs) increasing by 71%, from 253,679 in 2018 to 434,354 in 2024. SEND spending is out of control.

So what happened, exactly? The average child disability rate in Europe is 4.6%. How did the UK end up with 20%? Did the UK suffer a catastrophic nuclear event? A war? Famine? None of the above. It is clear that categorisation has become EXTREMELY loose over time on average. This does not mean that there are not children who are struggling to get diagnosed with ADHD. However ADHD and autism are a spectrum disorder. It is not binary. The UK has drawn the line far closer to the normal side of the spectrum than any other nation on Earth. If costs continue to rise at this rate, it risks destabilising the entire health system. Public sentiment will shift, and we risk undermining children getting any diagnosis at all.

IMHO, this requires at least two tactics at the same time. 1) Invest sufficiently into diagnosis resources. Stringing parents and children along for years while they wait in the system can make the issue much worse than it needs to be. 2) Draw the diagnostic line closer to where the rest of Europe does it. This will mean far fewer children are diagnosed with disabilities, but those who genuinely have a disability are treated much faster and actually receive the resources they need.
