Thank you for this video. It's interesting that such small differences are found on scans and yet the lived experience of ADHD feels like a huge difference to neurotypicals.

It would be super helpful for the high IQ/late diagnosis group. Many of us struggle to accept if we *really* have ADHD or not. What if we're just lazy and cheating both ourselves and the doctors? Also, other people think we're just using ADHD as an excuse and don't believe we really have it because we're smart. Please make a video about this group of ADHD.

It's worth it I think to consider that a "lazy person" may be "lazy" because of an underlying condition or set of circumstances. Most people don't "choose" to be lazy, certainly not over decades. I just feel that these general descriptive terms that we are accustomed to using, shouldn't be a vehicle for ending an inquiry. Terms like this, from a scientific perspective, really can only be taken as a simple description or single symptom and often not even so much as that. There's a thought experiment I encountered once, (and I'm not going to recite it perfectly); imagine a guy goes out and murders a bunch of people and then kills himself. One might say, he's evil, he's this or that negative thing. Only an evil person would decide to indiscriminately kill people after all. In his pocket they find a note that says something along the lines "I know this is wrong, I think there's something wrong with me, please look at my brain once I'm dead". So they do so, and they find cancer. Was the person "evil"? Did the description of "evil" do anything to address the actual cause of the actions? Was this action the persons fault or the fault of the cancer? Certainly we can be somewhat more sympathetic since we now know his brain was at the very least, not functioning correctly. But does a properly functioning brain have any greater free will? If you're "lazy" is that your "fault"? or is it simply that free will is always an illusion, and we are just following our programming for better or worse, however sophisticated that may be. At the end of the day, what constitutes a mental health condition is fairly arbitrary. So I think the key thing is, go get a diagnosis, be objective and honest, you would know if you were outright lieing, so don't do that. If it turns out you have it, then according to the DSM, you would fall in to the *category* of adhd, which itself has plenty of symptom diversity. So at that point you can start trying the various treatments, both medication and not, and see if that helps. Mental health in general, is just simply not as clear cut yet as some other medical professions, there's no way someone can yet do the equivalent of saying you have such and such specific type of infection and here's the cure. It's a process, often a nebulous one.

My experience is it's actually quite clear for individuals to tell if they have the requisite symptoms for an ADHD diagnosis. However, as you mention, acceptance is another thing entirely. Another commenter mentioned that Lazy may actually be caused by an underlying condition. I'd take it a step further, as the commenters quotation marks suggest, that the idea of "Lazy" can essentially be the same construct as "ADHD" just with two different explanations of the behaviour. Lazy = someone making the active choice to not do something when they or the observer believes they should be doing something. ADHD = neurodevelopmental condition that impairs action orientated behaviour and executive function through. These two explanations are essentially two levels of analysis. The first (lazy) is based on the perception that people are in-control of their choices; someone chooses to not do something. Whereas the second (ADHD) is based on the idea that brains function differently and that actions are the consequence of neural firing, structure, and blood flow

It's probably worth stating that just because these scans do not currently pick up signals that in general would discriminate between someone having ADHD and someone who does not, that does not imply that there aren't big differences going on in the brain. These scans simply do not pick up everything. A simple analogy that comes mind is taking a photo of someone from very far away. If the whole face of the person is only captured as a single pixel, you probably won't be able to tell what the colours of their eyes are. But that doesn't mean there aren't different eye colours. A question for Dr. Barkley: Do the theoretical models of ADHD make any strong predictions about how much better scanning methods would need to get to discriminate accurately? Essentially, do we have an idea about some scale, time scale and region of the brain where ADHD would be manifest?

To me it seems that the imaging of function and functional connectivity as the resolution improves will find much greater differences that might then work for individual diagnosis. The differences shown in tensor diffusion in white matter are much greater than regional MRI and so that may have more promise eventually for clinical use. I like your comment above. For instance, patients with early dementia known as mild cognitive impairment have significant problems with daily functioning yet scans can not yet pick up the brain changes until the cognitive deficits become even greater. Small changes in brain can have large behavioral effects, in essence. Be well.

Dr. Barkley! Thank you so much this video is exactly what I was looking for! I have been asking this question and you are the first to give an answer with an explanation! I also appreciate greatly your work and advocacy to expand knowledge and understanding of this disorder that is indeed non-fiction and not just an excuse for poor behavior. People with ADHD can be more tenacious than their peers and still not get anywhere, and neurotypical people see them as just a "screw up". Story of my life- because it's not a visible condition like a broken leg or Down's Syndrome, people assume one just wants an easy way out. No. I just want to be normal and I try so hard it is exhausting. Why would I CHOOSE to not get the passing of time in my head, resulting in great stress, day after day, despite the notes, alarms, medication, etc. Yeah if I could just fix that and be timely, that would be great 👌

Another invaluable video. Thanks Dr Barkley! If you have a moment I’d love to hear your thoughts on an open question about language in ADHD. In the last third of the discussion section of a 2017 research review (Korrel et al; Research Review: Language Problems in Children with ADHD - a systematic meta-analytic review), the authors state that a comprehensive neuroimaging study is needed that focuses on the language centers in ADHD children. They argue this would help answer the question of whether common language impairments in ADHD are caused by neurodevelopmental deficits to language centers (Broca’s, Wernicke’s, Heschl’s gyrus, etc, + relevant white matter tracts), or whether language impairments are only a secondary effect of underlying EF deficits such as working memory and sustained attention? We know the secondary impact is at least an important contributing factor. Whether language centers are impaired developmentally could inform whether interventions should target EF or speech/language. Do you agree that this question remains unresolved (language impairments a primary or secondary feature of ADHD)? If so, thoughts on what type of neuroimaging could be most appropriate for such a study?

10:53 There is a more fundamental point to be made here, which is that ADHD is a behavioral problem, not a physiological one. If somebody showed all the symptoms of ADHD and the brain scans DIDN'T show anything unusual, they would STILL need treatment. And vice versa: if someone showed all the signs of ADHD in the scan and none of the problematic behaviors, they would NOT need treatment. What that would mean is that we were wrong about the causes of the condition in the first place. Same can be said about depression, schizophrenia, autism and every other psychiatric and neurodevelopmental condition. Reducing a diagnosis to one scan or test implies we know a lot more about the human body and brain, their variation, and the mechanisms of a disorder than we actually do.

Very informative! I appreciated how you explained why this imaging is useful in aggregate but isn't individually diagnostic. I do wonder what role AI will play in this. I'm not sure if it's actually been rolled out yet, but there is/was supposed to be a public release of an AI program that can identify sex, smoking status, approximate age, and whether a patient is diabetic based on retinal scans. I wonder what - if any - patterns they might pick up on that we've missed in neural imaging.

16:10 I think that furthermore to those imaging devices becoming better, in order for them to be viable methods of diagnosis, theories of the brain need to become more accurate, and by accurate I mean empirically viable mathematical models that could explain those group differences. So I believe DTI + Topology from math should do it. Future clinicians will have to use a computer to analyze the data and extract useful parameters or graphs that should tell the differences.

Thanks for your kind comments on the value of my work to you. It is very much appreciated. So far functional connectivity scans have been very helpful in research comparing groups but that means little about their value in diagnosing individuals. I am hopeful that either that type of scan or one looking at white matter connectivity will prove more accurate for classifying cases. But we are not there quite yet. Be well.

Thank you very much, again, Dr. Barkley, for this helpful account on what brain imaging can and cannot do with respect to ADHD research and diagnosis. I wonder if you could say something about HDFT, high definition fiber tracking. My understanding is that it is a higher-resolution version of DTI - diffusion tensor imaging, albeit working somewhat differently. Developed at the University of Pittsburgh and CMU (based on ideas from a team in Taiwan), it is used to find fiber trajectories in the connective brain tissues, and to spot interrupted fibers due to brain injuries. It has also been used to map differences in connective tissues in people on the autistic spectrum. I am not aware of any uses for ADHD, so far, though. But maybe you could speak a bit about this? Does it have any value in ADHD research, or maybe even diagnosis, due to its higher resolution? Btw, I believe that this is an expensive technology, so maybe it is only available at the University of Pittsburgh, so far? Also, it seems difficult to find information about any potential improvements to spatial and temporal resolutions of brain scans that may be on the horizon. Is there anyone who could speak about this? Thank you again.

Are there other neurological diseases where such small differences have such a heavy impact on an individual's life?

While the differences in brain volumes are small and hard to see visually in just one persons scan, the techniques that give greater resolution and that evaluation white matter connectivity and its functioning are showing larger problems. I think that is telling us that the problems are with connectivity, functioning, and the variability of that functioning rather than an issue of simple brain or region volume alone. I am optimistic that a time will come when some imaging method will be clinically useful but we are not there yet.

Hi doctor! My psychiatrist prescribed me with Ritalin after seeing me for 30mins and hearing my symptoms (I believe I have ADHD and all of my symptoms fit pretty stereotypically across the board for all traits of ADHD). He told me instead of making me slog through various different tests with exorbitant costs he would rather prescribe the meds and see how I respond to them. He told me to finish a single pack of Ritalin (roughly 3 weeks supply) and keep in touch with him about the symptoms. After watching your video on JP's claims, wherein you mentioned that the paradoxical reaction was not a criterion for diagnosis, I began doubting the competence of my psychiatrist, however. Is there a cause for concern in my case?

Perhaps you got an answer elsewhere, here are my thoughts as a broadly experienced patient. I'm sympathetic to your concerns, I've been there. I often overthink things, everything, it's a key characteristic of ADHD, and I think you might have been overthinking it too. I agree with your doctor's approach. He's actually trying to save you time and money, imo. He is professional, trained in both psychology and full medical school. Will have a strong basis in neurology, understand medications, and had to pass at least two major exams for the MD and the Psychiatry specialty. He is functioning like an algorithm, which you would probably trust more. He has a dataset, his education, experience, and ongoing professional education and interactions. He has an analytical engine, his brain, and he is using that well-tuned system to make a judgement about your symptoms, history, and likely diagnosis. That's what Google does with you and your data when you type in a question about ADHD. Using treatment itself as part of diagnosis is common. If I have alot of tooth pain and have visible cavities, the oral surgeon could take a sample and get it cultured, but they prescribe antibiotics. When I take them the pain goes away and inflammation subsides. That confirms the likely diagnosis, it was a bacterial infection. Ritalin is listed as a stimulant but it's not really, it slows the reuptake of neurotransmitters while a true stimulant like amphetamines promote the release of those neurotransmitters. His decision seems very solid to me, and even considerate, as I mentioned above. It's been a year since you posted this question. If you see this I'm curious about the outcome. How did it go?

I can only speak for myself, but I thought I was developing dementia in my mid-twenties because I couldn't do math in my head anymore, I would lose my train of thought mid-sentence probably 40+ times a day, and I couldn't make it up a set of stairs without forgetting what I was up there for (then going back down, then remembering and going up, then forgetting again but bringing something else down), among other issues. In my case, it turned out to be the result of a handful of different mental health conditions (including ADHD) co-occurring, several of which are known to impair executive function/memory, and all complicated by heavy, chronic use of potent THC oil. Once I began to address these things one at a time, I did notice improvements in my memory. That might be true for you too, but maybe not. What's most important is that you seek help for your memory if it has gotten to that level. A doctor can help identify what the problem is in *your* circumstance (because it could be entirely different than mine), and then they can help you make a plan on how to proceed. Are you able to access a doctor? Or a psychologist?

Dr my son is very immature for his age. He has been correctly diagnosed with severe add. He has no friends in his grade. I have noticed that he likes playing with younger kids. Will he perhaps benefit from repeating a year at another school to be with peers more emotionally on his level? I am desperate.

In another video dr Russel said repeating a year is not good for adhd kids. He talks about the emphasis about learning a professional skillset that that has alot of benefit! Maybe this helps

So the differences aren’t obvious and stark enough. Also probably because EF deficit can be caused by different causes then. I was wondering about why imaging wasn’t used yet. According to the researcher in the following TED talk Lifelong Behavior problems may sometimes be explained by neuro imaging, but maybe because it has costs, and clinicians and hospitals can't just spend (machinery maintenance) for every cases. Québec (Canada) health regime is covering a lot. We get free healthcare, but the boundaries is about making sure people aren't suicidal. It must be a hard job to have to diagnose without doing every tests. In case.

10-25% percent difference in activity is not small. Especially because it can be compared for an individual between tasks and mental and arousal states in various ways. Also individual areas differences are bigger. Besides, there is spatial pattern as well. SPECT is not about a single scalar value for overall brain.

As someone who studied statistical analysis, I would strongly question the conclusion that the differences between averages are even relevant if the overlap is large enough to discredit the diagnosis of individuals. Overlaps of data clusters are even more relevant than the averages here because averages aren't physical things, averages are cherry-picked data points combined together as an aggregate value. Combining any amount of data from 2 subjectively picked categories on data that doesn't accurately correlate to the 2 is bound to have so much noise to signal ratio that even a difference in averages is meaningless. An analogous scenario would be to have a bunch of boxes of different colors containing either dark chocolate or white chocolate distributed within them by company affiliation of who makes the boxes and chocolates. Categorizing the boxes by color to assess the type of chocolate will give differences in averages with strong overlaps by pure chance without the color of the boxes or of the chocolates even being directly correlated because of the third factor of ''company affiliation'' making some statistically significant clusters of box colors/chocolate colors. The point is we subjectively observe ''behavior'' (box color) and try to determine an ''internal state'' (chocolate color) with a representation of the internal state such as brain scans (analogous to opening the boxes and recording the data for regressions) and the large overlap of data is indicative that the subjective observations of behavior are not directly related but indirectly correlated (by being subjective and not capturing an objective distribution, the observation doesn't capture the true underlying categorization, for the chocolates, the true categorization is the company affiliation that someone can't see, at least in this analogy). A large overlap likely means that psychologists and psychiatrists are so bad at categorizing objective behavior clusters accurately that a bunch of people within and without an objective brain structure cluster were both diagnosed and undiagnosed, meaning it's a game of coin toss as to if a ''professional'' even categorizes behavior properly and objectively. What this specifically tells us is that one should be extremely wary of any diagnosis around ADHD and behavior clusters. What it *doesn't* tell you is that studying averages between diagnosed and undiagnosed people shows the groups are distinct. That would be statistical mumbo jumbo, averages can tell you anything if you make them speak enough because they *aren't* tangible data.

Could it be that the reason neuro-imaging isn't an option is because ADHD is more about difference rather than disorder?

It’s about a difference that can lead to a disorder which, as I say in another lecture, is when a difference is enough to cause harm to the individual, or impairment in major life activities. No impairment, no disorder.

So take individual that has been clinically deemed to have ADHD and do the scans.Then scan the brain of the neuro-typical individual and compare the two. If the resulting activity of the ADHD brain is conformally showing the same across the set of people with ADHD then it should be obvious on the scan. If not then that states there isn't a glaring difference between the brain activity of neuro-typical and Neuro divergent brains. I'd say that there is a difference between electrical activity within the brains of people with ADHD, but I don't have the luxury of conducting the large swath of scans on both types of brains to validate what I'm saying.

Well, what this video shows is actually that perceived statistical relevance does not translate to real-world relevance. Meaning that these studies on ADHD produce bogus science, nothing else. We are still touching mud in relation to the very classification of what might be ADHD. This is far from one condition only, and it is mostly behavioural. We can't even be certain in saying that these brain differences are causation; they can very much be just the result of brain plasticity responding to environs. Dr. Barkley's effort to make science out of ADHD is respectable, just like every other scientific effort. However, the now-popularized discourse about brain activity and ADHD still needs many decades of refining to become something truly useful to clinicians.

@@mtbdog666 Finishing a PhD in Psych this year. I'm an M.Psych. and a BPsych. I gave you this piece of info despite seeing very little need to put my "credentials" to the test, especially because what I'm saying is talked about in the corridors of every university. The neuropsychological gaze is cute, but definitely not the best explanation for everything psychologically-related. And ADHD still needs a lot of work to be fully conceptualised. Hands-down much better nowadays than 30 years ago, but still a long way to go.

I can't agree that statistically significant in a population vs statistically significant enough to use as a diagnostic tool makes the studies "bogus". Much of the point of using statistical significance is to draw out findings which are important but not outwardly distinct. Bogus science would be claiming that this *is* useful for diagnosis.

@@Elspm, your point is valid despite interpreting what I said pretty differently from what I originally meant. Most probably because English is not my first language, which is something I unfortunately cannot fix. Anyway, this type of research has internal and possibly some minor external validity. And I stress that I didn't call Dr. Barkley's work bogus. He ardently dedicated his life to making a science of ADHD, which is something I honestly appreciate. Nonetheless, I am sceptical of any ecological validity of work that conceptualises ADHD neurophysiologically in the way it's been done lately. A good enough conceptualisation of ADHD is still to emerge. So, any work discussed in this video is rather preliminary and should be taken as such - despite being presented with a varnish of reality. I consider it "bogus" because it assumes a collection of non-pacified assumptions in its conceptualisation. ... and I was not even talking about "population", which is a complex idea, considering the crisis of replication in psychology.
