The Body Keeps the Score, But Can't Find the Words: Interoception, ADHD, and Trauma

Introduction: When Your Body Ignores Its Own Alarms

I hear a version of the same story often in my practice. A client describes weeks of feeling fine, competent, even productive, until suddenly they are not. The crash arrives without warning: a panic attack in a parking lot, a shutdown after a routine meeting, a body that simply stops. When we slow down and trace the timeline together, the truth is rarely that stress appears out of nowhere. It is that the body's early warning signals were never received.

This is not a failure of willpower, and it is not a character flaw. It is, for many adults with ADHD and a trauma history, a predictable consequence of diminished interoception, that is, the brain's capacity to accurately perceive and interpret its own internal state (Bruton et al., 2025; Fani et al., 2025). When ADHD and trauma occur together, as they frequently do, the result is what I have come to think of clinically as a double-blind spot: two overlapping conditions that each independently blunt the body's ability to signal distress before it becomes crisis.

In this article, I will define interoception, review what current research tells us about its disruption in both ADHD and trauma, explain why these two conditions compound one another, and outline evidence-based, neurodivergent-affirming practices for rebuilding body awareness. My aim is not simply to explain a mechanism; it is to offer language for an experience that many of my clients have lived without ever having the words to describe.

What Is Interoception, Exactly?

Beyond "Listening to Your Gut"

Interoception is frequently reduced, in popular usage, to a metaphor about intuition. Clinically and neurophysiologically, it means something more precise: the perception and interpretation of internal physiological signals, including heartbeat, hunger, fatigue, temperature, and breath (Bruton et al., 2025). It is not a single skill but a layered process, and Garfinkel's influential three-dimension model is useful for understanding why two people can have very different relationships to the same bodily signal (as cited in Bruton et al., 2025).

The first dimension is interoceptive accuracy, the objective ability to detect a signal, often measured through tasks such as heartbeat tracking. The second is interoceptive sensibility, a person's subjective belief in their own capacity to read their body, typically assessed through self-report measures such as the Multidimensional Assessment of Interoceptive Awareness (MAIA). The third is interoceptive awareness, a kind of meta-awareness in which a person can accurately judge whether their own body-reading is trustworthy in a given moment (Bruton et al., 2025). A client can, for instance, believe they are highly attuned to their body (high sensibility) while performing poorly on objective measures of accuracy; this mismatch is clinically significant, because it means the felt sense of self-knowledge and the actual reliability of that knowledge have become disconnected.

Why Interoception Matters for Self-Regulation

Accurate interoceptive signaling is not a peripheral bodily function; it is foundational to emotional regulation, decision-making, and impulse control (Bruton et al., 2025). Emotion itself is, in large part, built from interoceptive data; before the brain can label a feeling as anxiety, hunger, or grief, it must first register that something in the body has shifted. When that early registration is muted, the entire downstream process of naming, regulating, and responding to internal states is compromised.

I often offer clients this image: if your body's dashboard lights are dim, you will not notice you are running on empty until the engine stalls. The stall is not the problem; it is the outcome of a signal that was never received clearly enough, early enough, to prompt action.

Interoception in ADHD: The Research

What the 2025 Systematic Review Found

The most comprehensive evidence to date comes from Bruton and colleagues' 2025 systematic review in Psychophysiology, the first of its kind to examine interoception specifically in ADHD populations. The review screened 636 articles and ultimately included 17 studies meeting inclusion criteria (Bruton et al., 2025). Of the five studies directly comparing interoceptive accuracy between individuals with and without ADHD, three found significantly reduced interoception in the ADHD group. Twelve population-based studies further found that higher ADHD symptom severity, particularly inattention, impulsivity, and emotional dysregulation, correlated with lower interoceptive accuracy (Bruton et al., 2025).

The authors were appropriately measured in their conclusions, noting that many included studies had small samples and moderate methodological quality. Even so, the direction of the effect was consistent across the literature: ADHD is associated, with meaningful regularity, with a diminished capacity to accurately perceive internal bodily states.

What This Looks Like in Real Life

In session, this pattern rarely announces itself using clinical language. It shows up instead as a client who does not notice hunger until they are lightheaded or irritable, who misses the early tension cues that precede a meltdown until the meltdown has already arrived, or who experiences a form of time blindness applied specifically to bodily needs, such as holding a full bladder through an entire meeting or forgetting to eat until midafternoon. None of these are failures of discipline. They are, quite literally, a nervous system that has not received the early data it needed to prompt earlier action.

Trauma and Interoception: When the Body Goes Offline

Blunting Versus Amplification

Trauma disrupts interoception through a different, though related, mechanism. According to Fani and colleagues' 2025 review in Current Topics in Behavioral Neurosciences, trauma exposure can produce either blunted interoception, in which internal signals become muted and disconnected, or amplified interoception, in which the nervous system becomes hypervigilant and oversensitive to internal sensation. Notably, the strongest effects were observed in the context of chronic interpersonal trauma, including childhood maltreatment and experiences of racial discrimination (Fani et al., 2025).

This bidirectional disruption helps explain why trauma survivors so often describe contradictory experiences of their own bodies; some feel numb and far away from physical sensation, while others feel flooded by it, unable to distinguish a benign bodily cue from a threat signal.

Neurophysiology of the Disconnect

The neurophysiological substrates of this disruption involve the insula, the anterior cingulate cortex, and the vagus nerve, structures central to the brain's ongoing prediction and integration of bodily signals. Fani and colleagues (2025) describe this process through the lens of the Embodied Predictive Interoceptive Coding model, in which the brain continuously generates predictions about internal states and updates them based on incoming sensory data. Trauma appears to alter this prediction-sensation loop such that internal signals come to feel unreliable, or even dangerous, rather than informative (Fani et al., 2025). In other words, the body's own data stream becomes something to be avoided rather than trusted.

The PTSD-ADHD Overlap

PTSD and ADHD share a striking degree of symptom overlap, including hypervigilance, impulsivity, and emotional dysregulation, and both conditions are independently associated with interoceptive deficits (Bruton et al., 2025; Fani et al., 2025). This overlap raises a question I hold carefully with clients who present with both histories: is this ADHD, is this trauma, or is this both, operating together and compounding one another. In my clinical experience, the answer is very often the latter, and the distinction matters less for diagnostic tidiness than it does for designing a treatment approach that addresses the underlying interoceptive disruption directly, rather than treating only the surface-level behavioral symptoms.

The Double Hit: When ADHD Meets Trauma

Compounding Effects

When ADHD-related interoceptive deficits and trauma-related interoceptive disruptions occur in the same nervous system, the result is not simply additive; it is compounding. A client whose ADHD already delays the detection of internal cues, and whose trauma history has additionally taught the nervous system to distrust or disconnect from those cues, faces a genuinely double blind spot. The consequence is a heightened risk of emotional overwhelm, unexplained somatic symptoms, and significantly delayed help-seeking, because the very signals that would prompt a person to reach out for support are the signals least likely to register in time.

Why Standard Advice Fails

This is precisely why generic guidance to "listen to your body" or simply "practice mindfulness" so often falls flat, or worse, becomes another source of shame for clients who try and cannot seem to access what they are told should be readily available to them. When the body's signals are muted, distorted, or actively mistrusted, asking a person to listen more closely is not a neutral instruction; it can be an invitation into a system that has, for good reason, learned not to trust what it hears. What is needed instead is an approach that is trauma-sensitive and ADHD-informed by design, one that rebuilds the relationship to bodily signal gradually, with safety and predictability built into every step.

What Helps? Evidence-Based Practices to Rebuild Interoception

Mindfulness-Based Interventions

The evidence for mindfulness-based interventions (MBIs) in trauma populations is encouraging, though appropriately modest in its effect sizes. Molteni and colleagues' 2024 systematic review and meta-analysis in Psychiatry Research, drawing on twelve randomized controlled trials, found that MBIs produced small to moderate improvements in both interoception and trauma-related symptoms. Despite considerable heterogeneity across the included studies, sensitivity analyses confirmed that these findings held up under scrutiny (Molteni et al., 2024). Clinically, I have found that shorter, more structured mindfulness practices tend to be more accessible and more effective for adults with ADHD than the extended, unstructured sitting practices often associated with traditional mindfulness instruction.

Trauma-Sensitive Yoga and Somatic Practices

Trauma-sensitive yoga (TSY) offers another well-supported avenue for rebuilding interoceptive capacity, with feasibility research demonstrating reductions in distress and improvements in body awareness among trauma survivors. The core principles of TSY, namely choice, predictability, and invitational rather than directive language, are precisely what make it suitable for a nervous system that has learned to associate bodily attention with danger. These same principles translate well for ADHD clients, for whom autonomy and structure together, rather than either alone, tend to support sustained engagement.

Heartbeat Training and Biofeedback

Emerging work using heartbeat tracking and discrimination tasks, paired with real-time feedback, has shown promise for improving interoceptive accuracy in populations including autism and anxiety (Bruton et al., 2025). For adult ADHD clients specifically, I recommend adapting these approaches into gamified formats: brief sessions, visual or auditory feedback loops, and built-in variety, all of which align with what we know supports sustained attention and motivation in ADHD.

Practical, ADHD-Friendly Strategies

Beyond formal interventions, several low-barrier strategies can begin to rebuild the connection between body and awareness in daily life:

• Micro check-ins. Brief, thirty-second body scans conducted every two to three hours, prompted by a phone alarm rather than internal motivation alone, since internal motivation is precisely what interoceptive deficits compromise.

• Sensory anchors. Pairing interoceptive attention with an external, tangible cue, such as noticing the breath each time a bracelet or ring is touched, so that the external object does the reminding that the internal system cannot yet reliably do on its own.

• Body mapping. Drawing or journaling where tension, warmth, or numbness is felt in the body, which externalizes an internal process that may otherwise remain too vague or too threatening to name directly.

• Co-regulation. Practicing interoceptive attention alongside a therapist, coach, or trusted other, who can scaffold the process of noticing until the client's own system develops greater reliability

A Note on Culture and Context

Bruton and colleagues (2025) rightly conclude that future research must attend to cultural variation in interoception, since norms around body awareness differ meaningfully between collectivist and individualist cultural frameworks. I would extend this observation clinically: trauma originating from medical systems, from racism, or from gender invalidation can make the instruction to simply "tune in" feel unsafe rather than restorative. Any interoceptive work undertaken in therapy must account for the specific history a client's body carries, not only the diagnostic categories that history has produced.

Key Takeaways

Interoception is measurably diminished in both ADHD and trauma, and this diminishment makes self-regulation genuinely harder, not metaphorically harder. This is not a personal failure; it is a neurophysiological pattern with a growing and increasingly consistent body of research behind it. Rebuilding body awareness is possible, and it is best accomplished through practices that are simultaneously trauma-sensitive and ADHD-adapted, rather than generic in either direction. I encourage clients, and I will encourage you here as well, to start small, to prioritize felt safety over speed, and to seek professional support when the work of reconnecting to the body feels like more than can be held alone.
