Subtle Signs of Trauma, Part 2: When Trauma Looks Like ADHD, Autism, OCD, Anxiety, or Depression

Subtle Signs of Trauma, Part 2: When Trauma Looks Like ADHD, Autism, OCD, Anxiety, or Depression

In Part 1, I wrote about trauma symptoms that don’t look like mental health issues at all—chronic pain, digestive trouble, limerence, worthlessness. This post is about the opposite problem: symptoms that look very much like mental health issues and already have a name. Trouble focusing gets called ADHD. Intrusive thoughts and rituals get called OCD. Dread gets called anxiety, and flatness gets called depression.

Sometimes those diagnoses are exactly right. Sometimes trauma is doing a convincing impression of them. And very often both are true at once—someone has ADHD and a trauma history, or depression and PTSD, and each makes the other harder to treat.

I would like to be clear: I am not arguing that everything is secretly trauma. ADHD, OCD, and depression can all have organic causes in the brain. The point is that most psychiatric diagnoses are defined by what symptoms look like, not by where they come from. PTSD is one of the few exceptions: it can’t be diagnosed unless something happened. So when trauma is part of the picture and nobody asks about it, people can end up in treatment that helps only partway, without understanding why.

For each condition below, I’ll describe where trauma can fit in—sometimes it shows up a little differently, and sometimes it can’t be cleanly separated at all—and how trauma treatment can work alongside the standard treatment for that diagnosis.

1. Attention Problems and ADHD

Difficulty concentrating, losing the thread of conversations, restlessness, forgetfulness, impulsivity, procrastination. These are core features of ADHD. Several of them also appear in PTSD—difficulty concentrating is one of its formal symptoms—and the overlap is wide enough that researchers have been flagging it for decades, especially in children.

A few questions can help tease the two apart, though none of them is definitive. Was the difficulty present from early childhood and across every setting, or did it begin or worsen after something happened? Does it fluctuate with how safe you feel, getting worse when you are under stress?

When it’s both. Often it is. A 2016 meta-analysis found that the relationship runs in both directions: people with ADHD were more likely to develop PTSD, and people with PTSD were more likely to have ADHD, even when compared with people who had been through similar trauma. Growing up with undiagnosed ADHD in a world that punishes it can also be its own source of chronic stress and shame.

How treatments can work together. If you have ADHD, treating it—with medication, coaching, accommodations, or all three—can make trauma therapy more workable, because it’s hard to process anything when you can’t hold onto the thread. Trauma treatment, in turn, can quiet the constant scanning for danger that eats up attention, so ADHD supports have more room to work. For neurodivergent adults especially, a therapist who understands both neurodivergence and complex trauma means you don’t have to choose which part of you gets taken seriously.

2. Autism

Autism is not a mental illness, and trauma doesn’t cause it. Autism is a neurological difference that is present from birth. But being autistic and being traumatized are deeply intertwined, and several of their signs overlap closely enough that one is often mistaken for the other.

Being autistic is often traumatic in itself. Growing up autistic in a world built for neurotypical people usually means years of being misunderstood, corrected, excluded, or punished for the way your brain and body work. Bullying is common. Autistic adults report more traumatic experiences than their non-autistic peers, and studies consistently find more PTSD symptoms among them. In one study, 60% of autistic participants named a social event as the most distressing thing that had ever happened to them, compared with 20% of non-autistic participants. I’ve written more about this in my post on autism-informed trauma therapy.

Where the two look alike. Several features show up in both autism and trauma:

• Being triggered by social situations. For many autistic people, social interaction is overwhelming, because decoding unwritten rules, tone of voice, and facial expressions in real time takes enormous effort. For trauma survivors, social situations can set off the threat system: fear of judgment, rejection, or being found out. Both can mean dread before a gathering, exhaustion afterward, and a gradual pulling away from people. For many autistic people both are true at once, because so much of their trauma happened socially.
• Alexithymia. Alexithymia means difficulty identifying and describing your own emotions. A person with alexithymia may notice that something is happening in their body—a racing heart, a knot in the stomach—without being able to tell whether it is fear, anger, hunger, or excitement, and may struggle to put feelings into words. It does not mean having no feelings. A 2019 meta-analysis found alexithymia in about half of autistic people, compared with about 5% of non-autistic comparison groups. It is also common in PTSD, where shutting feelings down was once a way to survive.
• Masking and people-pleasing. Many autistic people learn to mask: suppressing stimming, rehearsing conversations, forcing eye contact, and copying other people in order to fit in. Masking looks a lot like the fawn response I described in Part 1—watching everyone else closely, becoming what they seem to want, and losing track of your own needs. Both usually start for the same reason: being yourself wasn’t safe. And both are exhausting. In one study, autistic adults said the sheer amount of time they spent camouflaging was what most damaged their mental health, and other research has linked camouflaging to higher rates of suicidal thoughts.
• Sensory overwhelm and hypervigilance. Autistic sensory sensitivity to loud rooms, bright lights, or scratchy fabric can look like the jumpiness and constant alertness of trauma. In a crowded, noisy space, both leave a person on edge and depleted.
• Meltdowns, shutdowns, and burnout. When an autistic person is overloaded, a meltdown or shutdown can resemble the fight and freeze responses of trauma. And autistic burnout, which often follows years of masking, can look a great deal like depression.
• A need for predictability. An autistic preference for routine and sameness can look like a trauma survivor’s need for control, which is often a way of staying safe in a world that once felt dangerous.

How treatments can work together. Autism itself isn’t something to treat or fix. What helps is trauma therapy adapted for autistic people: sensory-considerate, clear and predictable, and free of any pressure to mask. EMDR can be a particularly good fit, because it doesn’t require you to describe feelings you can’t yet name. Alexithymia, while common in autism, is a learned skill. Over time, both autistic and traumatized people can learn to notice body signals and connect them with emotions. If you have recently been diagnosed or are wondering whether you might be autistic, my work with adults after an autism diagnosis is built around exactly this overlap.

3. OCD

Intrusive, unwanted thoughts. Rituals that have to be done a certain way. Checking the stove five times, needing things to feel “just right.” OCD is a serious and often misunderstood condition, and it can also be tangled up with trauma.

Some people develop obsessive-compulsive symptoms after a traumatic experience, often organized around its theme: repeated washing after a sexual assault, compulsive checking of locks after a break-in, mentally reviewing every decision after an accident to make sure you didn’t cause harm. A review of the research on trauma-related OCD concluded that the overlap between OCD and traumatic histories is significant enough that trauma should be considered whenever OCD is being treated.

How trauma can look different. One useful distinction is the direction of the fear. PTSD intrusions are usually about the past: memories, images, or body sensations from something that already happened, arriving uninvited. OCD obsessions are usually about the future: what if I left the door unlocked, what if I’m contaminated, what if I hurt someone. Compulsions are attempts to neutralize those possibilities. In trauma-related OCD the two can blur, with rituals that are essentially an attempt to make sure the past never happens again.

How treatments can work together. The front-line treatment for OCD is exposure and response prevention (ERP), which helps people face what they fear without performing the compulsion until the fear loses its grip. ERP works well for many people. But trauma histories have been reported at high rates among people whose OCD doesn’t respond to standard treatment, and when a fear is anchored to an unprocessed traumatic memory, exposure can feel unbearable or simply not take. In those cases, processing the trauma first, or alongside ERP, can make the exposure work possible. EMDR is one option being studied here; a 2021 review of nine small studies found encouraging results for OCD symptoms, though the research is early and EMDR is not yet a substitute for ERP. Good care often means a trauma therapist and an OCD specialist working in coordination.

4. Anxiety

Constant worry, a racing heart, dread with no obvious cause, panic attacks, social fear, phobias. Anxiety disorders are among the most common diagnoses there are.

With anxiety, I would go further than I have with the other conditions in this post: in my view, trauma and experience always play a role. Temperament may make some people more prone to anxiety, but what we learn to fear, and how intensely, is shaped by what has happened to us. So the useful question usually isn’t whether experience is involved. It’s which experiences the anxiety is still responding to.

Sometimes the answer shows up in the anxiety itself. What feels like a sudden anxiety attack can actually be an emotional flashback—the feeling-state of an old experience, the dread or shame or helplessness, returning without the memory attached. The reaction seems out of proportion to the present because it is proportionate to something else.

Phobias. Phobias are often treated as isolated quirks: a fear of needles, or bridges, or certain animals that seems to have nothing to do with the rest of a person’s life. But the emotion at the center of a phobia can say a lot about where it comes from. Most phobias are built around fear, the sense that something is going to hurt you. Some are built around disgust instead—revulsion, nausea, a feeling of being dirty or contaminated, an urge to pull away or scrub something off your skin. In my experience, when a phobia centers on disgust rather than fear, it is usually a sign of sexual trauma. That isn’t something to conclude about yourself from a blog post. But if it resonates, it is worth exploring, at your own pace, with a trauma-informed therapist. Whatever their origin, phobias often respond well to EMDR.

How treatments can work together. Cognitive and behavioral approaches, breathing and grounding skills, and medication can all reduce anxiety, and they are worth having in your toolkit. Gradual exposure, the standard treatment for phobias, helps many people too. But because anxiety is rooted in experience, these tools often manage the alarm without changing why it keeps going off. Trauma processing addresses the memories the alarm is tied to, and somatic work helps the body learn, through experience rather than argument, that the danger is over. Many people use both: skills to get through the week, and deeper work so they need the skills less. If your anxiety hides behind productivity and achievement, this post on high-functioning anxiety may also be useful.

5. Depression and Anhedonia

Low mood, hopelessness, fatigue, guilt, withdrawing from people and things you used to enjoy. Often there is also anhedonia, the loss of the ability to feel pleasure: food is just fuel, music is just noise, good news lands with a thud. Depression and PTSD share a lot of ground. The PTSD criteria themselves include persistent negative emotions, harsh beliefs about yourself, feeling cut off from others, and a persistent inability to experience positive emotions such as happiness, satisfaction, or love.

How trauma can look different. Trauma-related depression often has shame at its center more than sadness—less I’ve lost something and more something is wrong with me. For some people it is closer to collapse than to grief: a shutdown in which a body that has been on high alert for too long simply powers down. It may also come in waves tied to anniversaries, certain relationships, or reminders, rather than holding steady.

Anhedonia, in trauma, is often one face of emotional numbing. A nervous system that learned to turn down feeling in order to survive can’t turn down only the painful feelings; the dial controls all of it. That numbing tends to come with detachment—feeling estranged from the people you love, as if behind glass—and people often describe it as flatness rather than sadness. It can sit side by side with a great deal of anxiety.

What the research says. Childhood maltreatment is linked to depression that is more likely to recur and persist, and a 2012 meta-analysis suggested people with these histories responded less well to standard depression treatment. A larger 2022 meta-analysis was more encouraging: people with childhood trauma started out more depressed, but they benefited from standard medication and psychotherapy about as much as everyone else. In other words, a trauma history is not a reason to skip medication if it is something you feel comfortable with.

How treatments can work together. Antidepressants can lift mood enough to make trauma work possible; it is very hard to process painful memories from the bottom of a depressive episode. Trauma therapy, meanwhile, can address the shame and the old conclusions that keep pulling people back down. They work best thought of not as competing options but as two layers of the same work.

With anhedonia specifically, behavioral approaches that gradually reintroduce rewarding activities can help, whatever its source. In trauma, it also helps to understand why pleasure may feel risky: for some people, joy means letting their guard down, and a guard that has been up for a long time doesn’t lower easily. As trauma processing reduces the sense of threat, feeling tends to return gradually—and grief often comes back along with joy, which is a sign of thawing rather than a setback.

6. Mood Swings That Look Like Bipolar Disorder

Intense emotions that arrive fast, a temper that flares and then floods you with shame, relationships that swing between closeness and rupture. People with these experiences are sometimes diagnosed with bipolar disorder when trauma is the actual cause of their symptoms.

How trauma can look different. Bipolar disorder involves distinct mood episodes that last days or weeks—periods of mania or hypomania, often with a reduced need for sleep, alternating with depression—and those episodes have a momentum of their own rather than shifting minute to minute with what’s happening around you. Trauma-related mood shifts tend to be faster and triggered: a perceived rejection, a raised voice, a reminder.

How treatments can work together. When trauma is driving the mood shifts, trauma treatment addresses what sets them off. When someone does have bipolar disorder, it generally calls for medication, and trauma therapy can be a valuable addition rather than a replacement.

Questions Worth Asking

If you’ve been diagnosed with one of these conditions and something still doesn’t fit, these questions may be worth bringing to your therapist or prescriber:

• When did this start? Was it always there, or did it begin or get worse after a particular period in my life?
• Does it get worse around certain people, places, times of year, or kinds of situations?
• Has treatment helped partway, while something underneath keeps pulling me back?
• Is there part of my history I’ve never told a clinician, or never thought of as relevant?
• Does my body react before my mind has had a chance to decide whether I’m in danger?

None of these answers will diagnose you. But they can change the conversation, and sometimes the treatment plan.

Trauma Treatment Isn’t Either/Or

If you’ve found medication, ERP, CBT, or ADHD coaching helpful, there is no need to give any of it up. Trauma therapy sometimes works best alongside other care, and with your permission it can include coordinating with your prescriber or other providers so everyone is working from the same picture.

Sequencing matters too. Trauma work generally starts with stability—enough sleep, enough support, enough regulation skills—before moving into processing memories. For some people, treating ADHD, depression, or OCD symptoms is part of building that foundation.

For the processing itself, I most often use EMDR, alongside somatic and parts work. And if you haven’t read it yet, Part 1 covers trauma symptoms that don’t look like mental health issues at all.

I see clients in person at my Upper East Side office, on the border of Carnegie Hill and Yorkville, and virtually across New York State. If you’d like help sorting out what’s driving your symptoms, you can read more about my approach to trauma therapy or reach out for a free consultation.
