Interoceptive Disruption designates the breakdown, distortion, or dysregulation of the processes by which the nervous system senses, interprets, and integrates signals originating within the body. Across the depth-psychology and psychophysiology corpus, no single consensus defines its precise contours, and this productive ambiguity has generated several competing orientations. Stewart and colleagues frame it primarily as a motivational deficit: disrupted interoception compels drug use as a corrective strategy against perceived internal imbalance, foregrounding negative reinforcement and withdrawal anticipation. Verdejo-Garcia distinguishes between failures of signal quality, perceptual accuracy, and appraisal, insisting that these sub-components carry distinct clinical implications and demand different interventions. Herman extends this to a feedback-loop model in which substance use both produces and is perpetuated by interoceptive deficits, while simultaneously tilting the interoception–exteroception balance toward external salience. Khalsa and the Interoception Summit 2016 position disruption within a hierarchical Bayesian framework, where attentional bias, blunted or heightened physiological sensitivity, cognitive catastrophizing, and impaired insight all constitute distinguishable failure modes. Naqvi and Bechara situate disruption anatomically in insular lesion data, demonstrating that damage to this hub can sever the conscious interoceptive representation that sustains addictive behavior. Khoury's review of randomized controlled trials suggests that targeted interoceptive interventions can partially remediate such disruption across panic disorder, eating disorders, and substance use. The concept thus bridges neurobiological, computational, and clinical registers, making it one of the more integrative constructs in contemporary psychopathology research.

interoception is believed to be disrupted as a result of substance use disorders, the precise nature of this disruption is still unclear. Given that over 50% of individuals with SUD and/or OUD relapse within a year of treatment, a nuanced understanding of interoceptive dysfunction within these disorders may facilitate targeted somatic interventions
Stewart establishes that interoceptive disruption is a recognized consequence of substance use disorders whose precise mechanisms remain unresolved, making its clarification essential to reducing relapse.

Substance abuse further disrupts the balance between interoception and exteroception (the perception of external stimuli), leading to hyperfocus on external stimuli and a decreased ability to perceive internal bodily sensations. This can result in the inability to recognize the harmful effects of drug use
Herman argues that interoceptive disruption in addiction operates as a shift in the interoception–exteroception balance, producing externally biased attention that obscures the harmful consequences of drug use.

Disturbances in these systems could have potentially very different clinical consequences and suggest different avenues for intervention. For example, if appraisal deficits are key for a client, then cognitive behavioural approaches focusing on interpretation of bodily cues are likely to be helpful.
Verdejo-Garcia argues that interoceptive disruption is not monolithic but comprises distinct sub-component failures—signal quality, perceptual accuracy, and appraisal—each requiring a different therapeutic approach.
Verdejo-Garcia, Antonio, The role of interoception in addiction: A critical review, 2012thesis
Interoceptive investigations in mental health populations might reveal evidence of 1) attentional bias (e. g., hypervigilance), 2) distorted physiological sensitivity (e. g., blunted or heightened magnitude estimation in response to a perturbation), 3) cognitive bias (e. g., catastrophizing in response to an anticipated stimulus), 4) abnormal sensibility, and 5) impaired insight
Khalsa proposes a multi-dimensional taxonomy of interoceptive disruption spanning attentional, perceptual, cognitive, and metacognitive failure modes across psychiatric populations.

Determining whether interoceptive processes are a cause or consequence of developmental psychopathology, and which factors might affect this development (such as early life stress or pain), will be an important area for future research.
Khalsa frames the causal directionality of interoceptive disruption—whether it precedes or follows psychopathology—as a foundational unresolved question, with early life stress identified as a key moderating factor.

the only regions in which lesions were significantly associated with an increased likelihood of having a disruption of smoking addiction were the right and left insulae.
Naqvi provides lesion-based evidence that insula damage is specifically and reliably associated with disruption of established addictive behavior, anchoring interoceptive disruption in a discrete neuroanatomical substrate.

damage to the insula leads to a profound disruption of addiction to cigarette smoking. A broad literature has addressed the role of the insula in processes related to conscious interoception, emotional experience, and decision-making.
Naqvi and Bechara establish the insula as the neural hub through which interoceptive disruption mediates the breakdown of addictive behavior, linking conscious body representation to decision-making.

drug use can be seen as a repeated perturbation of the current body state, which becomes associated with conditioned stimuli that may ultimately contribute to the sensitization of the body prediction error. In drug-addicted individuals the internally generated states are a result of long-term adjustments due to allostatic dysregulation
Paulus frames interoceptive disruption in addiction as the cumulative product of repeated pharmacological body-state perturbations that sensitize prediction-error signaling and entrench allostatic dysregulation.

deficits in decision-making are partly related to a deficit in the ability to use emotion-based bodily signals to guide behavior. Individuals with poor IA, who are unable to effectively utilize bodily signals and rely on non-emotional sources to guide their decision-making, may choose more dis
Sübay links interoceptive disruption to impaired somatic-marker guidance in decision-making, positioning deficient body-signal utilization as a downstream consequence that sustains addictive behavior.

chemogenetic silencing of the aIC→AcbC projections potentiated and produced 'alcohol-like' effects. silencing of this aIC→AcbC circuit decreased alcohol self-administration under baseline conditions
Lovelock demonstrates that disruption of the anterior insular cortex–nucleus accumbens core circuit reproduces interoceptive effects of alcohol and modulates self-administration, specifying a circuit-level substrate for interoceptive disruption.

psychiatric disorders often promote or reflect the development of chronic homeostatic and allostatic disturbances, there is a need for methods capable of eliciting homeostatic perturbations in controlled settings, especially those assessing subjective and behavioral responses to valence and arousal deviations.
Khalsa situates interoceptive disruption within the broader category of chronic homeostatic and allostatic disturbance, arguing for experimental perturbation paradigms as the appropriate methodological response.

interventions targeting interoceptive regulation may offer a potential benefit for various types of psychiatric disorders. This demonstrates the need for more well-designed RCTs across several categories of psychiatric diagnoses investigating the efficacy of interoception-focused interventions

a prenoetic disruption of affect is important. The retentional-protentional structure of consciousness is constitutive of self-identity within the changing flow of consciousness; it generates the basic sense of auto-affection or ipseity.
Gallagher offers a phenomenological counterpart to neurobiological accounts, framing prenoetic disruption of bodily self-affection as the experiential substrate from which more specific interoceptive disturbances may be understood.
