In short

Autism is a neurodevelopmental disorder that must be present from early development and needs some level of support. Autistic traits are common in everyone and are not the disorder. The diagnosis is a very broad bucket, so take the differential seriously (personality disorders, psychosis, and whatever is acting on lifelong traits in a late presentation) and get history from more than one source. Of the theories, systemizing versus empathizing explains the most.

What it is

  1. Autism spectrum disorder is high systemizing and low empathizing, plus a collection of associated problems (repetition, emotional regulation problems, some learning problems) downstream of genetics and neurobiology, at a level that makes it a disorder rather than traits.

    “autism spectrum and the autism disorder Disorder is where you have high systematizing, systemizing, low empathy, and probably a collection of other associated issues and symptoms that come together with the neurodevelopmental Downstream to genetics and neurobiology, repetition tendency, emotional regulation problems, some learning problems”
    52:45Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  2. It is a neurodevelopmental disorder: the features must be present in the early developmental period and come from neurodevelopment.

    “for it to be autism spectrum disorder, they must be present in the early developmental period. And it's part of the neurodevelopment. That's the cause, okay”
    9:36Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  3. It is typically recognized in the second year of life. Regression after age two does not rule it out, but look more closely at other explanations.

    “it mentions that this is typically recognized within the second year of life. And if someone has a regression after two years, it's not saying that it's not autism spectrum disorder, but you need to have a closer eye to looking at other things”
    10:17Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026

The DSM-5 criteria

  1. Criterion A is persistent deficits in social communication and social interaction across multiple contexts, in three subcategories.

    “A is persistent deficits in social communication and social interaction across multiple contexts. And then it gives three different subcategories of that”
    4:10Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  2. Criterion B is restricted, repetitive patterns of behavior, interests or activities, two of four. The first is stereotyped or repetitive movements, use of objects or speech, such as hand flapping, lining up toys or echolalia.

    “Criterion B, the second arm, is restricted repetitive patterns of behavior, interests, or activities, manifested by two of the followings. It lists four things. The first is stereotyped or repetitive motor movements, use of objects, or speech. Some examples, hand flapping, lining up toys, echolalia, when you repeat back something you hear”
    7:34Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  3. Criterion D requires clinically significant impairment, and E requires that it is not better explained by intellectual disability or global developmental delay.

    “D is symptoms must cause clinically significant impairment in social, occupational, or other important areas. And then E is just not better explained by intellectual disability or some global developmental delay”
    13:49Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  4. Level 1 is "requiring support." That tells you something: a DSM-defined autism spectrum disorder means you need some kind of support, and that is probably where the bar for disorder sits.

    “Level one is requiring support, okay? So that should tell you something, I think. The idea is that if you have a DSM-defined autism spectrum disorder, you need some kind of support. That's probably the bar that they are drawing there for whether or not it's disorder”
    20:20Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  5. Specifiers include with or without intellectual or language impairment, association with a known genetic, medical or environmental factor, and association with another neurodevelopmental, mental or behavioral problem.

    “You can specify with or without accompanying intellectual impairment, with or without language impairment. You can specify associated with a known genetic or medical condition or environmental factor. And you can also specify associated with a neurodevelopmental, mental or behavioral problem”
    19:09Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  6. There is a catatonia specifier for autism. Most people think of psychotic disorders for catatonia, even though it is more frequent in bipolar disorder.

    “It's the catatonia specifier. I don't know if most people know that they specifically included a catatonia specifier with catatonic features for autism spectrum disorder. I think most people think of the psychotic disorders when it comes to catatonia, even though they're more frequent in bipolar disorder”
    18:19Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026

Other common features

  1. A typical defining feature is an uneven profile of abilities: incredibly intelligent in one area, with a mismatch in others.

    “The defining thing that you typically see in those patients is an uneven profile of abilities. They'll be incredibly intelligent in one area. And then in particular areas, there's a mismatch”
    26:44Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  2. Theory of mind problems are common, but their source and how they show up differ from the mentalization problems of personality disorders.

    “We also commonly see problems with theory of mind or mentalization. And the source of this, we probably should consider as separate and different than the ones that we see in the personality disorders”

    “And the way that it manifests is very differently. In autism, there's one test that it's... There's two kids on the end of a box and one kid's touching the box and the other kid's looking at the box”
    28:16Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  3. Executive dysfunction is a big one. ADHD used not to be diagnosed alongside autism because executive dysfunction was considered part of autism, and it may truly be a separate issue from ADHD.

    “Executive dysfunction, I think, is a big one. In fact, back in the day, they wouldn't even diagnose ADHD if you could justify a diagnosis of autism spectrum disorder because executive dysfunction was considered a part of autism spectrum disorder”
    25:52Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
    Also said in 1 more episode
    “ADHD used to not be co-diagnosed with autism for a reason. And it's possible that the executive dysfunction that you see in autism is actually a separate issue than the ADHD issue”
    54:43How to Decide When ADHD Is Actually ADHDNov 2025
  4. Also common: motor clumsiness, GI problems, sleep-wake and circadian problems, self-injury under distress, emotional dysregulation and irritability.

    “There's neurological motor symptoms, clumsiness. You can see GI problems. You can see sleep-wake cycle problems, circadian rhythm problems. There's also some tendency for self-injury, especially in the context of distress. And there is naturally emotional dysregulation and irritability”
    27:44Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  5. Aggressive outbursts in more severe autism usually come from poor emotional regulation, often triggered by changes in routine, unexpected outcomes or secondary mood problems.

    “We definitely see in more severe autistic conditions, aggressive outbursts, and that's usually due to poor emotional regulation, right? Often triggered by things like changes in routine, unexpected outcomes, or simply mood problems that are secondary to the autism”
    38:39The Psychology of Elizabeth Holmes in You Can See Everything: Narcissism, Autism, or Manipulation?Oct 2026
  6. Language in autism tends to be concrete and particularly detailed, not slippery or vague.

    “the concrete use of language in autism should actually do the opposite. In general, people who have autistic disorders and use language in a very concrete way tend to be particularly detailed about their use of language”
    34:34The Psychology of Elizabeth Holmes in You Can See Everything: Narcissism, Autism, or Manipulation?Oct 2026

Traits versus disorder

  1. Autistic traits include specific, constrained interests, trouble with social communication and cues, organizing the world into a predictable system, sensitivity to certain stimuli, liking routines and not doing well with change.

    “people who tend to have very specific And constrained interests, people who struggle with social communication and understanding social cues, people who like to organize their understanding of the world into a very predictable system, people who are sensitive to certain types of stimuli, who like routines, who don't do well with change”
    26:41The Psychology of Elizabeth Holmes in You Can See Everything: Narcissism, Autism, or Manipulation?Oct 2026
  2. These traits are present to some degree in the general population, with no bright line or objective measure for when they become a disorder. It is a clinical judgment call.

    “They are actually present to some degree in the general population. And there's no bright line about when that becomes a disorder or not, right? We don't have a objective way to measure that. It's totally clinical judgment call”
    11:58Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  3. A single observed moment tells you about traits, not disorder, and says little about why someone did something.

    “one moment like that alone, again, only tells us about traits, right? It doesn't tell us anything about disorder, and it particularly does not allow us to come to much in terms of conclusions about why someone did what they did in terms of a criminal charge”
    30:19The Psychology of Elizabeth Holmes in You Can See Everything: Narcissism, Autism, or Manipulation?Oct 2026
  4. Those things are not outside the realm of normal variation, so do not attribute them to anything in particular.

    “I would not say that those things are outside the realm of normal variation. So I wouldn't attribute that to anything in particular”
    The Psychology of Seinfeld: What’s Really Wrong With George, Kramer, Jerry & Elaine?Aug 2026
  5. The neurodiversity movement frames autistic traits as healthy human variation, but in some sense, rather than de-pathologizing autism, we have pathologized normal traits.

    “There's social reasons for what you're describing. The autism rights movement, there's a big push for a neurodiversity framework, which pushes autistic traits as healthy variation of the human condition rather than a disease and a disorder. And in some sense, rather than de-pathologizing autism, we've pathologized normal traits”
    13:10Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  6. Building an identity entirely around a set of traits and a disorder can create a very different life for you and the people around you.

    “If you create an identity entirely around having this set of traits and having a disorder, you might create an entirely different life for yourself and the people around you”
    27:33The Psychology of Elizabeth Holmes in You Can See Everything: Narcissism, Autism, or Manipulation?Oct 2026

Theories

  1. No single theory can explain something as complex as the brain. Treat the theories as complementary snapshots: sometimes an older one captures a patient better, sometimes a newer one.

    “It's helpful to view it as like each theory is a different, they're trying to get more and more aspects of it, but sometimes an older theory will better capture a patient and sometimes one of the newer theories will better capture a patient”
    35:49Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
    Also said in 1 more episode
    “it is basically impossible to explain anything as complicated as the brain's functioning with one theory or even a A few sets of theories. Each theory is some inaccurate and imperfect way of using human language to capture this complex system in a little snapshot”
    36:38Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  2. The most compelling one, though not the most politically correct, is systemizing versus empathizing, with the general population spread along both.

    “But the one I like the most, and again, not exactly a politically correct hypothesis to like the most for autism, but I think the most compelling one is the systematizing versus empathizing versus autistic traits breakdown of the general population”
    40:32Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  3. Systemizing is the drive to analyze or build systems: picking up the rules and regularities that govern a system so you can predict how it will behave.

    “So systemizing is the drive to analyze or construct systems. So- What defines a system is that it follows rules. So when we systemize, we're trying to identify the rules that govern the system so that we can predict how that system will behave. So you systemize by picking up on the regularities and the rules”
    42:40Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  4. Split empathizing into cognitive empathy, intellectually understanding what someone feels or wants, which is learnable, and affective empathy.

    “There's a very useful split we can make in empathizing, one being cognitive empathy and And one being affective empathy. We might be able to intellectually understand what someone else is feeling or wanting. That's cognitive empathy. That's learnable”
    43:19Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  5. People with clinically identifiable autism show more systemizing than even the general-population male, whatever their own sex.

    “Also, you will see in the clinically identifiable autism spectrum disorder population, Those patients will have more systemizing than even the general population male, whether or not they are male or female themselves. What else should we know”
    44:51Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  6. The social motivation hypothesis says people with autism find social input less rewarding and pay less attention to faces and gaze.

    “This one is basically the idea. It's sort of a psychological idea that children or people with autism, they find social stimuli inputs less rewarding. We see that they attend less. They pay less attention to faces and gaze”
    37:13Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  7. We do not buy its assumption that social capacity is simply learned; it is something more fundamental in the biology of brain functioning.

    “it assumes that all social reactivity, everyone's capacity to do social things is simply a matter of learning. And I don't believe in that personally. I do think it's something more fundamental, something within the neurodevelopmental, the biology of the brain functioning”
    39:00Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  8. Weak central coherence theory and the mind-blindness theory of theory of mind deficits are two other frames.

    “This is called the weak central coherence theory. Right, right. That's the official term. There was also then another hypothesis about deficits in theory of mind. Deficits in theory of mind. We already talked about that a little bit. The mind blindness theory”
    40:11Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  9. There may also be a double empathy problem, in which other people fail to empathize with the autistic person.

    “there could be a double empathy problem. And I will just say, before I say more on this, life is very cruel. And there's not much we can change about that, in my opinion. I'm very cynical”
    45:59Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026

What it gets confused with

  1. The dividing line with personality disorders: is it inability to understand others' emotions, or lack of interest?

    “is that personality or is it simply that they lack conscious understanding or have a lot of difficulty understanding the emotions of others? Right. Is it inability or lack of interest? That's the dividing line. We want that dividing line between autism and personality disorders”
    38:07The Psychology of Elizabeth Holmes in You Can See Everything: Narcissism, Autism, or Manipulation?Oct 2026
  2. Many patients with personality disorders feel a neurodevelopmental label fits them better, and a clinician should be able to tell when personality pathology is what is going on.

    “I see a lot of patients with personality disorders who feel the neurodevelopmental label fits them better. For a clinician to be able to easily tell that it's not a neurodevelopmental issue, there's personality pathology kind of going on”
    15:12Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  3. The DSM notes that autistic behavior can be perceived as narcissistic, schizotypal or schizoid personality, and the opposite is true too.

    “the DSM actually specifically notes that behaviors associated with autism spectrum disorder can be perceived as symptoms of narcissistic, schizotypal, or schizoid personality. And that schizoid, sorry, schizotypal personality I'm going to say that's absolutely true, and the opposite is true too”
    30:45Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  4. There is a large mutual blind spot between the clinicians and researchers who focus on personality disorders and those who focus on neurodevelopmental disorders, with too little coordination.

    “there is a large mutual blind spot between both clinicians and researchers who are interested in and recognize personality disorders on one hand and neurodevelopmental disorders like autism spectrum on the other hand. There's not enough coordination between these groups in research or clinical settings”
    15:31Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  5. Failure of empathy does not explain borderline conditions; it is not a well-supported hypothesis when empathizing is measured in people with BPD.

    “I was curious about whether neurodevelopment could explain what we today consider borderline conditions, BPD, even antisocial or narcissistic. What if it's a failure of empathy? Well, not a well-supported hypothesis. They've looked at empathizing. Systems in people diagnosable with borderline personality disorder”
    49:12Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  6. Psychopaths have the opposite profile: strong cognitive empathy and poor affective empathy. Autistic people appear to have some internal affective reaction to others.

    “If you look at psychopaths, they actually have the opposite profile to autism spectrum disorder. They have really good cognitive empathy. They're strong in cognitive empathy, unlike autism spectrum disorder. They have bad affective empathy. And I think there's actually research to show that autistic individuals actually have some internal affective reaction to other people”
    50:14Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  7. Childhood-onset schizophrenia has a period of normal or near-normal development before the prodrome, and the prodrome's atypical interests and social impairment can look like autism.

    “When you consider schizophrenia, especially of childhood onset, you will have some period of normal or near normal development before the onset of the prodrome. And in the prodromal psychotic state, you can definitely see atypical interests, beliefs, social impairment, and that can look like the social deficits and fixated interests seen in autism spectrum”
    29:20Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  8. Autism and odd personality traits mimic psychosis, but they are also risk factors for true psychosis.

    “while autism and general personality oddness is a mimic for true psychosis, we should also note that those conditions are risk factors for true psychosis as well”
    38:06What is Psychosis? Look at the DSM, Common Mimics, and a Framework for the DifferentialJan 2026
  9. Autism and schizophrenia can co-occur, probably with a shared genetic risk pool, and it can get very confusing which one you are dealing with at a given time.

    “Autism and schizophrenia can also co-occur, and actually there's probably a shared gene risk pool here, so it gets very, very confusing, and I've treated numerous individuals with both, and it can get so confusing about which one you're dealing with at a particular time”
    30:15Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  10. The field does not capture the crossover genetic risk between psychotic disorders, bipolar disorder, OCD and autism well, so do a careful evaluation in those overlap cases.

    “I think, again, we are touching upon our inability as a field to correctly capture the crossover genetic risk between psychotic disorders, bipolar disorders, OCD and autism. I would just do a careful eval on those”
    40:49Practical OCD Psychopharmacology: Evidence‑Based (& Non Evidence-Based) Medication ApproachAug 2025

Pitfalls

  1. We have seen numerous adults first evaluated and diagnosed with autism after the clear onset of schizophrenia.

    “I have seen numerous cases now of Autism Spectrum Disorder being diagnosed in adults after the onset of schizophrenia. I'm not kidding. I am not kidding. The first testing and evaluation for autism is taking place after the clear onset of schizophrenia”
    11:00Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  2. If someone goes 30 years in a modern Western society without an autism diagnosis and then develops new difficulties, consider everything else that could be interacting with a baseline of autistic traits.

    “if someone can go in a modern Western society for 30 years without an autism spectrum diagnosis, and then they begin to have new difficulties, I think you're doing a disservice if you don't consider all the other things that could be interacting with a baseline of autistic traits to produce now a global psychological or psychiatric disorder”
    33:40Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  3. Diagnoses are most valid when based on multiple sources: clinician observation, caregiver history and self-report.

    “diagnoses are most valid and reliable when based on multiple sources of information, including clinicians, observations, caregiver history, and self-report”
    32:05Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  4. When a patient asks to be evaluated for a named disorder, the structured interview for that disorder almost guarantees the diagnosis.

    “it's almost as if asking the question begets an interview that's guaranteed to get that diagnosis when you do the structured interviews that are for those specific diagnoses”
    2:48How to Do a Psychiatric Intake | The Art and Science of the First HourSep 2025
  5. The DSM is not aggressive enough about "not better explained by," probably because the people who framed the diagnosis mostly work with children.

    “I don't think they are aggressive enough about the not better acceptable aspect. Yeah, the differential diagnosis. And I think it's probably because autism researchers and the framers of the definition of this diagnosis probably mostly work with children”
    14:09Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  6. Autism is a gigantic bucket of very different pathologies. The same diagnosis covers a top-tier programmer who needs prompting for appointments and a person whose main activities besides self-care were spinning and hitting people, and a category that broad tells us little.

    “If this single diagnosis accurately describes both these people, then that makes that diagnosis kind of useless, right, as a category. If you make your diagnostic category super broad, then it doesn't tell us anything at all”

    “something like autism is a gigantic bucket capturing patients with totally different pathologies, even if there's some convergence with regards to the social communication and repetitive behaviors”
    21:54Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
    “both my friend who is a top tier programmer at fang companies and makes like half a million dollars a year, but also will forget things and needs prompting for appointments. Has the same diagnosis as the former patient I had who basically had two major activities besides ADLs spinning around and hitting people”
    23:30Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026
  7. Overdiagnosed or underdiagnosed is a false dichotomy. Both are true.

    “there's a false dichotomy that either you think it's overdiagnosed and all these people think they have autism when they don't, or you think it's underdiagnosed and there's people suffering who have a diagnosis that's underdiagnosed. And the much more obvious route is that both are true”
    17:24Autism Diagnosis Explained: DSM-5 Criteria, Autistic Traits & the Difficult DifferentialSep 2026

Treatment

  1. The antipsychotic evidence in autism is for controlling unwanted or disruptive behaviors, not for quasi-psychotic symptoms or general functioning. Do not give them to high-functioning people without severe disruptive behaviors.

    “that is not for the treatment of quasi-psychotic symptoms, and it is not for general functional improvement so much as it is for the control of quote-unquote unwanted or disruptive behaviors. You should not Give those to high-functioning people who don't have severe disruptive behaviors”
    35:43What is Psychosis? Look at the DSM, Common Mimics, and a Framework for the DifferentialJan 2026
  2. Do not be afraid to try mood stabilizers. There is probably a lot of genetic and pathophysiological crossover between bipolar disorders, schizophrenia and sometimes OCD, ADHD and autism.

    “do not be afraid also to use mood stabilizers. We don't understand these categories as much as we think. And I think the reality is that there's probably a lot of genetic and pathophysiological crossover between the bipolar disorders and the schizophrenia and sometimes OCD, ADHD, autism”
    12:36Mood Stabilizers for Bipolar Disorder: Lithium, Lamotrigine, Depakote & MoreJul 2026
  3. With autistic traits but not ADHD, sleep-wake dysregulation is common; reach for something not habit-forming.

    “someone who seems to have neurodevelopmental but not adhd uh like autistic traits uh often you see dysregulation the sleep-wake cycle i'm going to give something not habit forming”

  4. Some workplaces, such as Microsoft and Ernst & Young, have tried management styles, rules and environments suited to people with autistic traits.

    “There have been attempts in some workplaces to institute management styles, rule sets, and also environments that are more conducive to people with autistic traits. However, it should not surprise you to learn that two major companies that have done this include Microsoft and Ernest & Young”
