Lumos Newsletter

Imagine for a second trying to memorize a really complex quantum physics textbook. Oh, that sounds rough already. Right. But now imagine trying to do that while standing in the middle of a loud, flashing, totally chaotic arcade. Like the bells are ringing, neon lights are blinding you, people are

bumping into your shoulders. Yeah. I mean, no one is passing that test. Exactly. If I hand you a quiz 10 minutes later, you are probably going to fail. But what if the problem, you know, wasn't your intelligence? What if the problem wasn't the

Welcome to today's Deep Dive. If you are joining us, it's because you are, well, you're that insanely curious learner who always wants to look under the hood of human behavior. You're looking for those hidden mechanical gears that drive how we act, how we think, how we interact. And

today we have a really phenomenal mission. We are cracking open a stack of research from the Lumos newsletter, specifically edition 009. And it completely flips the script on neurodivergent behaviors, especially regarding autism and ADHD. Okay, let's unpack this. Because we aren't just doing some dry medical review today.

We are completely refraining the things that society constantly, you know, slaps the label on and just dismisses as bad behavior or defiance. Yeah, we are going to look squarely at the biological realities driving those behaviors. Because when you dig into the neurological mechanisms coming out of these recent

studies, you quickly realize something huge. What looks like a refusal to cooperate or maybe slowness is actually just the brain's sensory and cognitive filtering systems working in an entirely different way. Our goal today is to basically strip away the assumptions and stop moralizing behavior and look at the

actual gears turning inside the brain. Let's start right there with those gears, specifically how the brain filters information, or in a lot of cases, struggles to filter it. Right. So the Lumos newsletter highlights this really interesting study published in Science Advances. They used a video game called Geode

to study visual perception across the autism spectrum. And importantly, this included individuals with profound autism, which is a group that often gets left out of cognitive research entirely. Yeah, which is a huge gap. So what they found completely redefines what it means when an autistic individual is labeled

a quote unquote slow learner in a new environment. The traditional and frankly quite outdated assumption has always been that if someone with autism is learning a new task slowly, there's just a fundamental lack of cognitive capacity, like a deficit model. But the GEODE study disrupts that entirely, doesn't

it? It really does. They found that autistic participants were taking longer to learn, not because they lacked the capacity to understand the primary task, but because of something the researchers called sensory noise. Sensor noise. OK, so we are back in the arcade. Exactly. What does that actually look

like on a neurological level? Like, why is the brain struggling to just focus on the screen? What's fascinating here is the mechanics of the brain's sensory gating system. Every single second, our nervous system is bombarded with millions of bits of data. Visuals, sounds, the feeling of your socks

on your feet, the hum of the refrigerator. Things we don't even notice most of the time. Right. A neurotypical brain has a highly automated filtering system. It basically subconsciously tags most of that data as safe and irrelevant, and it pushes it to the background. That way, the conscious

mind can focus purely on the primary task. But for the autistic participants in the study, that sensory gating system is like highly porous? Yes. The brain is letting all that environmental data in at an equal volume. It treats the hum of the fridge and the texture of the

sock with the exact same level of urgency as the textbook you're trying to read. Meaning the background static isn't getting muted at all? Not at all. So the individual isn't slow. Their brain is simply processing a vastly larger data set than a neurotypical brain is in that exact

same room. The bottleneck is the environment, not their intelligence. Wow. And the study highlighted a really crucial metric. This level of sensory noise was actually a better predictor of a person's daily functioning than their core autism diagnosis. Wait, really? That is wild to think about. The label of

the diagnosis itself tells you

Scientific research about autism subtypes, genetics, autism subtypes. Two hosts. Why won't they focus? The question you should be asking an occupational therapist is, is sensory noise hindering this routine? You literally have to turn off the flashing lights of the arcade before you open the textbook. Exactly. You have

to lower the sensory noise. But that brings us to a really glaring question. If the arcade is this overwhelming and sensory noise is this critical to how a person functions day to day, how is the medical field missing it? That is the million dollar question. Right. Which leads

us to our next source. It's a study from the Irish Journal of Psychological Medicine looking at a massive diagnostic blind spot between ADHD and autism. This is such a systemic issue in psychiatry right now. Historically, the medical model really prefers neat, tidy boxes. You know, you meet the

criteria for ADHD or you meet the criteria for autism. And the treatments are totally distinct. The therapies are distinct. Everything is separate. But this new study looked at young adults diagnosed with ADHD, and it revealed that a staggering 53% of them also meet the full criteria for autism.

Here's where it gets really interesting. Wait, 53%? Over half. If the overlap is that massive, how on earth is the medical system missing this? Are the symptoms identical or are doctors just stubbornly staying in their silos? Because, I mean, if I go to the doctor for ADHD and

they give me standard ADHD medication, but I'm actually in that 53% who also has autism, my sensory issues aren't going to get fixed by a stimulant. No, they won't. And the symptoms are not identical, but they frequently mask each other. Often the hyperactivity or severe inattention of ADHD

is like the loudest symptom in the exam room. It's the one causing trouble in class. Right. It is externalized. It disrupts the classroom. So it draws the doctor's focus and that gets the diagnosis. Meanwhile, the underlying autism, the internal sensory overwhelm, the social exhaustion is totally ignored. Or

it's misinterpreted simply as a byproduct of the ADHD. Wow. And the research specifically noted that women and girls in particular show much higher sensory sensitivities that go completely unrecognized in these overlapping cases. Why is it always women and girls who slip through the cracks in these diagnoses? Well,

it often comes down to internalizing versus externalizing behaviors, which is heavily driven by societal expectations. Girls are often socialized to mask their discomfort and just, you know, blend in socially. Right. Don't make a fuss. Exactly. So instead of disrupting the class when the sensory noise gets too loud,

they internalize it, which looks like inattention or anxiety. The doctor sees the inattention, diagnoses ADHD, and stops digging. But the key takeaway for you listening is the necessity of a neurodevelopmental approach. Meaning we look at the whole brain, not just the loudest symptom. Precisely. If someone you love

or you yourself has an ADHD diagnosis, but it's still profoundly struggling with social interactions, rigid routines or sensory environments and standard ADHD treatments aren't moving the needle, you have to look deeper. You have to push for more answers. You need to actively investigate those autistic traits with a

neurologist. Bringing up this 53% overlap is crucial because transitioning into adulthood with only half of your neurological profile supported is just a recipe for severe burnout. Okay, so we have sensory noise causing learning hurdles and we have a medical system that often completely misses that sensory picture. So

what happens when those ignored sensory issues boil over? Oh, they definitely boil over. Because when that sensory noise becomes too much, it erupts. And let's be real, as a society, we are uniquely terrible at interpreting that eruption. Well, we absolutely are. We tend to moralize distress. We call

it a tantrum. We label it bad behavior. But Lumos Edition 009 brings us this fascinating study out of Taiwan, published in Frontiers in Psychology, and it focuses on preschoolers. A really critical age for this. Yeah. The researchers looked at the direct link between sensory processing, So kids who

avoid sensory input or are hypersensitive to it and their capacity for self-regulation. And they found an undeniable biological link to aggression and anxiety. This study is vital because it recodes our fundamental understanding of distress. Let's look at the biology of what is actually happening. When a child is

hypersensitive to their environment, their nervous system isn't just annoyed. It is interpreting that sensory input as a physical threat. So like an itchy wool sweater isn't just an uncomfortable piece of clothing to their brain. It is a blaring fire alarm. That's the exact mechanism in play. Because of

that porous sensory gating we talked about, the sensation bypasses the logical reasoning center of the brain, the prefrontal cortex, and it goes straight to the amygdala, the brain's threat detection center. So it triggers a literal fight or flight response. Yes, the resulting behavior, the screaming, the hitting, the

fleeing is a meltdown. And we have to clearly differentiate a meltdown from a tantrum. Because they look identical on the outside, right? Like it's a kid screaming in a grocery store. On the surface, yes, they look the same. But internally, they are entirely different events. A tantrum is

behavioral. It is driven by the prefrontal cortex. The child is trying to achieve a desired outcome, like, you know, getting a candy bar or staying up late. And if you give them the candy, the tantrum magically stops. Exactly. Scientific research about autism spectrum, genetics, autism subtypes, robot therapy.

Two hosts. So if you're listening to this and you've ever felt totally helpless watching a child scream, this completely changes your role. Instead of immediately issuing a timeout to punish a tantrum, we should be acting like detectives. We should be scanning the room for a flashing light, a

high-pitched hum, a restrictive shirt tag. If we connect this to the bigger picture, it changes the entire paradigm of discipline. Alesha Dixon, Ph.D.: Adjusting the environment prevents dysregulation far more effectively than traditional behavioral correction. Because you can't logic someone out of a fight or flight response. Alesha Dixon,

Ph.D.: You cannot punish a nervous system into feeling safe. If you observe a meltdown, your first thought shouldn't be, how do I correct this defiance? It should be, what is the sensory trigger? Once you remove the trigger, the biological threat response can finally begin to settle. It's an

incredibly empowering shift. You aren't fighting the child, you're fighting the environment alongside them. Now, sensory overload is a very acute, immediate trigger, but what if the room is perfectly quiet? Right, no sensory triggers. What if there are no flashing lights, no itchy sweaters, and a child is still

hopelessly stuck on a really basic daily routine? The newsletter points out a completely different hidden hurdle that impacts long-term daily independence. Let's talk about something as simple as getting dressed in the morning. This is where we move from sensory processing over to cognitive processing. The newsletter covers a

study published in Research in Developmental Disabilities. They evaluated autistic children between 7 and 12 years old using something called the BADLE scale. Okay, I saw this acronym in the research, BADLE. What exactly does that measure? Because getting dressed sounds like a basic motor skill to me, not some

complex neurological puzzle. BADLE stands for Basic Activities of Daily Living Evaluation. It assesses fundamental tasks for independence like eating, personal hygiene, and dressing. And you're right. Historically, when an autistic child struggles to gain independence in these areas, people just assume it's a motor skill issue or maybe just

a core symptom of autism preventing them from participating. But the study proved something entirely different, didn't it? Completely different. The data show that executive functioning is far more critical for daily independence than core autism symptoms or motor skills. Okay, executive function. That is one of those clinical buzzwords

that gets thrown around a lot. Let's break down the mechanism. Because if a kid is struggling to put on a shirt, it's not that their fingers lack the coordination to push a button through a hole. No, it's actually a sequencing problem. Think of Scientific research about autism subtypes,

Hi, this is Alex and I'm here to talk about the Alex and Jamie.

Scientific host, Scientific Welcome back. Welcome back.

You're welcome. We're glad to be here. So in order for you to be able to get started with this podcast, you should ask your occupational therapist specifically to evaluate executive function and help you build these external scaffolds. That is such great advice. So we've looked at the internal

hurdles. We understand the biological reality of sensory noise and those sequencing crashes of executive dysfunction. But we don't live in a vacuum. No, we don't. We live in a world built almost exclusively for neurotypical brains. So how do we successfully adapt the rigid systems of the outside world

to accommodate That

really is the ultimate goal of all this research. Translating all this understanding into tangible societal change. And the final article in this NW edition gives us a brilliant, highly practical example of doing exactly that. In one of the most notoriously rigid, sensory unfriendly environments out there, primary healthcare.

The doctor's office, just thinking about it, honestly, the harsh fluorescent lights The creatures around them never turn a blind eye.

And there are real answers to their questions.

Stereotypes of non-autistic people have much to do with that. And you designed it with the people it affects. Yes, that is key. And the intervention they introduced wasn't some million-dollar technological overhaul of the clinic. It was incredibly simple, just a pre-appointment questionnaire. A questionnaire. Why does that make

such a massive difference? It really comes down to shifting the cognitive load. The questionnaire flagged the patient's sensory and communication needs before they even stepped foot in the clinic. It allowed the patient or their advocate to explicitly state, here is what Thank you for joining us and welcome

to the A.L.T.E.

Podcast.

We are here to talk about autism spectrum.

We are going to talk about the two main types of autism spectrum.

The first tipo of autism spectrum is an autoimmune disorder. It's a symptom of an autoimmune disorder called autism spectrum.

The autoimmune disorder is an autoimmune disorder that is caused by the loss of blood and blood pressure. It can be caused by the lack of blood pressure or the lack of blood pressure, which can But the researchers found another vital benefit. It massively boosted clinician confidence. Oh, really?

Yeah. For the doctors? Yes. Doctors genuinely want to provide good care, but they're rarely trained to navigate profound sensory needs on the fly. Having the data beforehand allowed the medical team to proactively prepare the room and themselves. So what does this all mean for you? How do you,

the listener, actually use this tomorrow? You don't have to wait for your clinic to formally offer an adapted health check. You can just Hi Jack the concept. I highly recommend doing that. Next time you schedule an appointment for a neurodivergent child or even for yourself, just call ahead,

send a message through the patient portal, tell the pediatrician beforehand about specific biological triggers. Tell them, hey, a cold stethoscope triggers a fight or flight response. Can the doctor warm it up in their pocket first? Or please remove the paper from the exam table. You proactively act as

the sensory filter for that environment. I couldn't agree more. You have to advocate for those environmental adaptations. The study emphasizes that you aren't just being difficult or demanding. This is a science-validated strategy. Adapting primary care in this way is highly feasible. It costs clinics almost nothing. And it

fundamentally removes the barriers that prevent neurodivergent people from accessing basic healthcare. It's just good medicine. Okay. Let's take a breath and look at the sheer amount

We also unpack the biology of a meltdown. We're recognizing that it is an involuntary amygdala driven threat response to sensory input, which is entirely different from a behavioral tantrum. And we learned that fostering independence isn't just about motor skills, right? It's about supporting the brain's air traffic controller,

its executive ability to sequence tasks. And finally, we saw proof that when we adapt our rigid environments, like using a really simple pre-appointment questionnaire to shift the cognitive load at the doctor's office, We can completely transform the experience of existing in the world. Which brings us to the

end. This raises an important question though. One that I think naturally flows from every single mechanism we've discussed today. We've seen how the environment, not the individual's inherent capacity, really dictates the outcome in all of these studies. Which leaves me with this thought for you to chew on

as you go about your day. If all of these studies definitively prove that the environment, whether it's the visual static in a classroom, the rigid setup of a medical appointment, or the overwhelming texture of a shirt, if the environment is the primary trigger for distress... Or learning barriers.

Yeah. Right. How much of what society labels as a disability would simply disappear if we just designed a world that wasn't so incredibly loud and flexible and demanding? It's a really powerful thought. It really is. Thank you for joining us on this deep dive. Keep asking questions. Keep

looking beneath the surface. And we will catch you next time.
