Is It Autism or CPTSD? Why So Many Adults Are Misdiagnosing Themselves Online

Written by Stephanie Underwood, RSW

In recent years, there’s been a noticeable rise in adults—especially women and highly self-aware individuals—wondering whether they might be autistic. Social media platforms are filled with videos, infographics, and personal stories describing “autistic traits” that often sound remarkably relatable: social exhaustion, a need for routine, sensory sensitivities, or difficulty expressing emotions.

But here’s the problem: many of these so-called “symptoms” are not actually exclusive to autism. The majority of them are human experiences—especially common among those who grew up emotionally neglected or without secure attachment. Which is a much higher percentage than people actually think. And while it’s important to validate diverse neurotypes and make space for late-diagnosed adults, it’s equally important not to confuse trauma responses or personality adaptations with a clinical diagnosis of Autism Spectrum Disorder (ASD).

In this blog post, we’ll unpack the growing trend of self-diagnosing autism in adulthood, why so many trauma survivors resonate with these traits, and how to begin distinguishing between autism and the long-term effects of emotional neglect. The goal isn’t to invalidate anyone’s experience—but to ground this conversation in clarity, compassion, and context.

What the DSM-5 Actually Says About Autism

To understand the difference between autism and other forms of emotional or psychological adaptation, we need to start with what autism actually is—according to clinical standards.

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition. This means it originates in brain development, with symptoms typically present from early childhood—even if they’re not recognized until much later. The gold standard for diagnosis in North America is the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).

According to the DSM-5, a diagnosis of autism requires difficulties in two major domains:

1. Persistent deficits in social communication and social interaction

This means ongoing challenges—not just awkwardness or social anxiety, but genuine difficulties in:

• Back-and-forth conversation and emotional reciprocity

• Nonverbal communication, such as eye contact, facial expressions, gestures, and body language

• Understanding and maintaining relationships, including adjusting behavior in different social contexts

These difficulties must occur across multiple settings, not just in one area of life.

2. Restricted, repetitive patterns of behavior, interests, or activities

This includes at least two of the following:

• Repetitive motor movements (e.g., hand-flapping, rocking), use of objects, or speech (e.g., echolalia)

• Insistence on sameness, inflexible adherence to routines, or ritualized patterns of behavior

• Highly fixated interests that are abnormal in intensity or focus

• Hyper- or hypo-reactivity to sensory input (e.g., being very sensitive to sounds or textures)

  
  

Additional diagnostic requirements:

• Symptoms must have been present in the early developmental period, even if they become more noticeable under stress in adulthood.

• Symptoms must cause clinically significant impairment in social, occupational, or other areas of functioning.

• The presentation is not better explained by an intellectual disability or global developmental delay.

What’s important here is that the DSM-5 focuses on impairments that are rooted in brain development and evident from early life, even if they’ve been masked, misunderstood, or compensated for over time. Autism isn’t just a set of quirks or sensitivities—it’s a fundamental difference in how someone processes social, sensory, and emotional information.

Autism Must Begin in Childhood

One of the most important distinctions about autism is that it is neurodevelopmental, meaning the differences in brain development are present from an early age. While many adults are diagnosed later in life—especially those who were overlooked due to masking, gender biases, or coping mechanisms—the core traits must have existed in childhood.

This is a critical point: you cannot “develop” autism as an adult. Even if the challenges only become noticeable under stress, trauma, or life transitions, the neurological wiring has been there all along. This separates autism from trauma-based behaviors, which often emerge as adaptive responses to the environment, rather than innate differences in neurobiology.

In contrast, other diagnoses—like PTSD, Complex PTSD (CPTSD), or emotional neglect-related difficulties—are acquired over time in response to chronic stress, unmet needs, or adverse experiences. While they may look similar on the surface, they come from very different places—and require different approaches to healing.

When Emotional Neglect Mimics Autism

Many adults who resonate with “autistic traits” are, in fact, carrying the invisible wounds of emotional neglect. Unlike abuse, emotional neglect is the absence of something essential: emotional presence, attunement, validation, and safety. When these core needs aren’t met in childhood, a person adapts—not because of neurodivergence, but because they had no other choice.

These adaptations can look strikingly similar to autism. But their origin is environmental, not neurological. They’re not signs of how your brain was built—they’re signs of how your nervous system learned to protect itself in an emotionally unsafe environment.

Let’s explore how emotional neglect can mimic autism across key domains:

1. Social Disconnection or Awkwardness

• If no one modeled safe, healthy relationships, it’s common to feel unsure of how to “do” connection.

• You may struggle with eye contact, small talk, or social cues—not because of innate social processing differences, but because your emotional world wasn’t mirrored or nurtured.

• Trust may feel dangerous. Vulnerability might feel foreign.

2. Emotional Expression Difficulties

• People who grew up emotionally neglected often suppress or disconnect from their emotions to survive.

• This can resemble alexithymia (difficulty identifying and expressing emotions), which is common in autism—but in this case, it’s often a trauma response.

• If your feelings were ignored, minimized, or punished, you learned to shut them down.

3. Sensory Sensitivities

• Emotional neglect and chronic stress can dysregulate the nervous system, leading to heightened sensitivity to noise, light, texture, or touch.

• This hypersensitivity isn’t the same as sensory processing differences in autism, but it can feel just as overwhelming—because your nervous system is on high alert.

4. Rigidity and Need for Control

• For those raised in emotional chaos, routine and predictability can feel like safety.

• You may cling to sameness, structure, or rituals to avoid overwhelm—again, not because of autism, but because unpredictability once meant emotional threat.

5. Hyperfocus or Obsessive Thought Patterns

• Trauma survivors often ruminate, overanalyze, or “hyper-fixate” as a way to feel in control or make sense of pain.

• This can mirror autism’s focused interests—but here, it’s often about managing anxiety or unresolved emotional wounds.

These patterns are deeply human responses to not having your emotional needs met. They’re not flaws. They’re evidence of your capacity to adapt, survive, and protect yourself in an environment that didn’t nurture the full range of your humanity.

Why the Rise in Misidentification Matters (and What It’s Really About)

At first glance, self-identifying as autistic might seem harmless—especially if it brings someone relief, language for their experiences, or a sense of understanding they never had growing up. And to be clear: many people who explore this path are doing so with genuine self-reflection and a desire to understand themselves better.

But there’s a deeper layer here that often goes unspoken.

For many trauma survivors—especially those who felt unseen, misunderstood, or emotionally abandoned—diagnostic labels can offer something profoundly important: a sense of belonging.

When you grow up without emotional validation, it’s easy to internalize the belief that something is wrong with you. You feel different, disconnected, out of place. So when you stumble across a list of “autistic traits” online and see yourself reflected there, it can feel like coming home. Finally, you have a name for your struggles. Finally, there’s a community that gets you.

But here’s the risk: when the source of your pain is misidentified, your healing can be misdirected.

If you’re navigating the emotional aftermath of childhood neglect—but treating it like a neurological condition—you may bypass the core wounds that need tending:

• The grief of not being nurtured.

• The shame of feeling like a burden.

• The deep hunger to be known, accepted, and safe in relationship.

  
  

These are not clinical traits. These are attachment wounds. And they need a different kind of care—one that centers healing, not just identification.

Absolutely. Here’s a clear and compassionate explanation of CPTSD that can be included before we move into the final section:

What Is Complex PTSD (CPTSD)?

Complex PTSD (CPTSD) is a trauma-related condition that develops from prolonged, repeated exposure to relational trauma—especially during childhood. While PTSD is often associated with a single traumatic event (like an accident or assault), CPTSD results from chronic trauma that occurs over time, often in environments where the individual feels trapped, powerless, or unsafe.

This type of trauma usually occurs in the context of relationships—such as growing up with emotionally unavailable, abusive, neglectful, or inconsistent caregivers. Over time, these experiences deeply shape a person’s sense of self, their ability to regulate emotions, and their capacity to trust others.

Core Features of CPTSD:

In addition to the symptoms of standard PTSD (like flashbacks, hypervigilance, nightmares, or emotional numbness), people with CPTSD often experience:

1. Emotion Regulation Difficulties

   • Intense emotional reactions, such as anger, shame, sadness, or fear

   • Difficulty calming down once triggered

   • Emotional numbness or dissociation

   
   

2. Negative Self-Concept

   • Chronic feelings of worthlessness, guilt, or shame

   • Internalized beliefs like “I’m broken” or “I’m too much”

   • Harsh inner critic and self-blame

   
   

3. Relational Struggles

   • Difficulty trusting others or feeling safe in relationships

   • Avoiding intimacy or, conversely, clinging to unsafe attachments

   • Fear of abandonment, rejection, or conflict—even in safe contexts

     
     

4. Identity Confusion

   • Feeling disconnected from your authentic self

   • Struggling to know what you want, need, or feel

   • Adapting to fit others’ expectations, often at the expense of your own identity

   
   

CPTSD is not about weakness or over-sensitivity—it’s the body and mind’s natural adaptation to long-term emotional injury. And like autism, it’s invisible to the outside world. But unlike autism, CPTSD is not inborn—it’s learned through survival. And the good news is: what was learned can be unlearned. Healing is possible.

How to Tell the Difference Between Autism and CPTSD

Autism and Complex PTSD (CPTSD) can look surprisingly similar on the surface. Both can involve social difficulties, emotional dysregulation, sensory sensitivities, and a strong need for control or predictability. But while the behaviours may overlap, their underlying causes—and the paths to healing—are entirely different.

Understanding the distinction between these two experiences can help you find clarity and access the kind of support that actually meets your needs.

Let’s look at some key differences:

1. Origin Story

• Autism is present from early development. It’s rooted in neurological wiring and often noticed (at least subtly) in childhood—even if it’s misinterpreted or missed.

• CPTSD is acquired. It develops in response to chronic, relational trauma, often from repeated emotional, physical, or psychological harm in childhood—especially when there’s no escape.

2. Relationship to Emotions

• Autistic individuals may struggle with emotional recognition and expression due to differences in how their brains process emotional cues.

• CPTSD survivors often suppress, disconnect from, or become overwhelmed by emotions because feeling was unsafe. Emotional shutdown or outbursts are protective, trauma-adapted responses.

3. Social Interaction

• Autism often involves difficulty interpreting social cues regardless of the emotional stakes.

• CPTSD may lead to withdrawal, people-pleasing, or hypervigilance in relationships—but these patterns usually stem from a fear of abandonment, rejection, or criticism, not from innate social processing differences.

4. Sensory Sensitivities

• Autistic sensory sensitivities are typically lifelong and consistent, related to neurological processing differences.

• CPTSD-related sensitivities are often nervous system responses to trauma, and may fluctuate depending on stress levels, safety, or emotional states.

5. Motivation Behind Behavior

• In autism, repetitive behaviors or routines can bring comfort, regulation, or joy.

• In CPTSD, routines and control are often used to manage anxiety, avoid triggers, or prevent chaos.

6. Identity and Self-Concept

• Many autistic individuals describe feeling “different” their entire lives, even before experiencing trauma.

• CPTSD survivors often feel like they became different over time—gradually losing trust in themselves, others, and the world due to repeated betrayals or emotional invalidation.

This is not about putting people in boxes—it’s about asking:

• Where did this come from?

• What was I trying to protect myself from?

• And what do I actually need to feel safe now?

Absolutely—this final section will bring everything together with a focus on the importance of accurate diagnosis, the psychological impact of labels, and how clarity leads to real healing.

Where to Go From Here: Moving Toward True Healing

If you’ve seen yourself in both autism traits and trauma patterns, you’re not alone. Many adults—especially those who are introspective, emotionally aware, and shaped by difficult early relationships—find themselves caught in the grey area between self-identification and clinical clarity.

But this is where it becomes crucial to pause and reflect on the power of a diagnosis—and the responsibility that comes with it.

Labels Shape Identity

Humans are meaning-making beings. We naturally seek out labels to help make sense of who we are, where we belong, and why we feel the way we do. When we finally find a label that “fits,” it can feel incredibly validating—especially after years of feeling different, misunderstood, or broken.

But labels are also psychologically powerful. Once internalized, they can become part of your self-concept—sometimes in ways that limit growth.

• A person who adopts the identity of “I’m autistic” when they are, in fact, navigating CPTSD, may begin to explain away trauma responses as permanent traits.

• They may stop seeking healing because they believe the pain is wired in, rather than wounded in.

• And tragically, they may miss out on targeted support that could help them recover, rewire, and reconnect.

Accurate Diagnosis Matters

When it comes to mental health, getting the right diagnosis is not just about labeling—it’s about direction. It’s about understanding what is truly driving your experiences so that your care can be as personalized and effective as possible.

• Autism and CPTSD require very different approaches to support.

• Misdiagnosis can lead to inappropriate interventions, missed opportunities for healing, and a skewed sense of what’s possible.

• Proper diagnosis, ideally through a trained mental health professional who understands both neurodevelopment and trauma, can offer not just clarity—but a roadmap.

It’s also okay to sit in the uncertainty for a while. Self-exploration isn’t a race. Whether you’re neurodivergent, trauma-impacted, or both—your experiences are valid, and your story matters.

Final Thoughts

Before you adopt any label as part of your identity, ask yourself:

• What am I really hoping this label will give me?

• Does this label feel like freedom—or a cage?

• Have I explored the roots of my struggles from multiple angles—trauma, neurobiology, attachment, environment?

You deserve to be understood—fully, and accurately. And you deserve healing that goes beyond explanation. Because knowing “what you are” is only the beginning. The deeper journey is about understanding who you are beneath all the adaptations.
