Interoception, ADHD, and the AuDHD Child in Your Clinic

What Is Interoception, and Why Does It Matter for ADHD?

Interoception is our sense of the internal body. It alerts us when we are hungry, thirsty, tired, cold, anxious, or overstimulated. It also alerts us to rising arousal levels. Without reliable interoceptive processing, self-regulation becomes reactive rather than proactive.

In children with ADHD, interoceptive processing is frequently and significantly disrupted. Emerging research confirms that interoceptive differences in ADHD are closely linked to emotional dysregulation, difficulties with self-monitoring, and challenges generalising self-regulation strategies because all three of these depend on access to the internal body signals that interoception provides.

Put simply: you cannot regulate something you cannot feel. When a child's interoceptive system is unreliable, self-regulation strategies are not accessible. The strategies may be learned but the early warning signal is missed entirely and therefore any learned strategy cannot be used. By the time the child knows they are dysregulated, its too late.

The Regulatory Loop ADHD Breaks

Regulation is not a single skill. It is a loop: detect a signal → interpret it → respond to it. For this loop to work, the first step of detection must be reliable. Children are often taught the response (breathe, take a break, use a fidget) without first addressing whether they can detect the signal first.

This is why sensory strategies can feel hit-and-miss in clinic. A child who cannot reliably detect that their arousal is rising will not independently use a sensory tool at the right moment. They will use it reactively, after the fact, or not at all.

The AuDHD Complexity: When Two Systems Compound

In recent years, clinical practice has made clear what research is now catching up to: the co-occurrence of autism and ADHD,  increasingly referred to as AuDHD. It creates a distinct and complex clinical presentation that we need to understand on its own terms.

Both autism and ADHD carry significant interoceptive disruption independently. In autism, this is well-documented. In ADHD, interoceptive disruption compounds already fragile emotional regulation. When both are present, the child is navigating a nervous system that is simultaneously under-registering internal body signals, over-responding to the external sensory environment, seeking proprioceptive and vestibular input to regulate, and experiencing rapid, intense emotional fluctuations that arrive without internal warning.

The AuDHD child in your clinic may present as explosive and then genuinely confused about what happened. They may be intellectually aware of regulation concepts (able to explain what a "calm-down corner" is for) while being unable to access that knowledge in the moment of dysregulation, because the interoceptive signal never reached conscious awareness in time. They may also be masking which means the meltdown arrives even more suddenly when the mask slips, and the child is even further depleted.

Practical Clinical Suggestions: Where to Start

Interoceptive work does not require a separate programme but can be threaded into existing sensory and regulation-focused OT practice from the very first session. Here are some starting points:

Interoception will not be the answer to every ADHD challenge. But needs to be considered in all clinical pictures, as addressing it early can shift the entire trajectory of intervention.
