Background Obsessive–compulsive disorder (OCD) patients typically overmonitor their own behavior, as shown by symptoms of excessive doubt and checking. Although this is well established for the patients’ relationship with external stimuli in the environment, no study has explored their monitoring of internal body signals, a process known to be affected in anxiety-related syndromes. Here, we explored this issue through a cardiac interoception task that measures sensing of heartbeats. Our aim was… 

Interoceptive deficits in patients with obsessive-compulsive disorder in the time course of cognitive-behavioral therapy

It is demonstrated that IAcc is affected in patients with OCD and this deficit does not change during the time course of a standardized therapy and whether an inaccuracy in perceiving one’s bodily signals constitutes a risk factor for relapse.

Interoception and Obsessive-Compulsive Disorder: A Review of Current Evidence and Future Directions

Disrupted interoceptive processes are present in a range of psychiatric conditions, and there is a small but growing body of research on the role of interoception in obsessive-compulsive disorder

Functional neural mechanisms of sensory phenomena in obsessive-compulsive disorder.

Altered Interoceptive Processing in Generalized Anxiety Disorder—A Heartbeat-Evoked Potential Research

The results suggest that altered cortical processing of interoceptive signals may play an important role in the pathophysiology of generalized anxiety disorder.

Obsessive-compulsive tendencies are related to seeking proxies for internal states in everyday life.

Altered neural signatures of interoception in multiple sclerosis

MS patients were characterized by atypical multimodal brain signatures of interoception, which opens a new agenda to examine the role of inner‐signal monitoring in the body symptomatology of MS.



Overactive Performance Monitoring as an Endophenotype for Obsessive-Compulsive Disorder: Evidence From a Treatment Study.

This is the first longitudinal study in adult OCD patients showing stability of enhanced error monitoring following successful symptom reduction through CBT, and supports the hypothesis that overactive performance monitoring is an endophenotype that indicates vulnerability for OCD.

Overactive error-related brain activity as a candidate endophenotype for obsessive-compulsive disorder: evidence from unaffected first-degree relatives.

Overactive error monitoring may reflect a trait marker for OCD that is independent of the presence of clinical symptoms, and enhanced error-related brain activity represents a candidate neurocognitive endophenotype for OCD.

Specificity of performance monitoring changes in obsessive-compulsive disorder

Distinct neural correlates of washing, checking, and hoarding symptom dimensions in obsessive-compulsive disorder.

The findings suggest that different obsessive-compulsive symptom dimensions are mediated by relatively distinct components of frontostriatothalamic circuits implicated in cognitive and emotion processing.

Overactive performance monitoring in obsessive–compulsive disorder is independent of symptom expression

Overactive brain processes during performance monitoring are a neural correlate of OCD that is independent of global symptom severity and can be observed for all symptom dimensions.

Feeling, learning from and being aware of inner states: interoceptive dimensions in neurodegeneration and stroke

This is the first study in which a multiple lesion model reveals fine-grained alterations of body sensing, offering new theoretical insights into neuroanatomical foundations of interoceptive dimensions.

Cortical Representation of Afferent Bodily Signals in Borderline Personality Disorder: Neural Correlates and Relationship to Emotional Dysregulation.

IMPORTANCE The ability to perceive and regulate one's own emotions has been tightly linked to the processing of afferent bodily signals (interoception). Thus, disturbed interoception might contribute
