Interoception has historically been assessed using behavioural tests of accuracy, self-report measures or through the characterisation of neural signals underlying interoceptive processing. More recent conceptualisations of interoception incorporate interoceptive attention and higher-order measures related to the interpretation of interoceptive signals. At present, these interoceptive dimensions are largely assessed in isolation, yet this fails to capture the complexity of interoception. Comprehensive assessment across interoceptive dimensions can determine the full operation of general interoceptive function. Current work suggests that these interoceptive processes may be dissociable across dimensions and bodily axes, with differential mapping to cognitive and emotion processing. To characterise differences in interoceptive profiles, all interoceptive dimensions can be assessed within individuals, both within a single bodily axis (e.g., cardiac) or across bodily axes. Future work can better delineate how these interoceptive measures correspond to different types of processing. Comprehensive interoceptive assessment can help isolate selective interoceptive disruptions in different clinical conditions.

Background: This paper reports on the outcomes of a proof-of-principle study for the Exposure Therapy Consortium, a global network of researchers and clinicians who work to improve the effectiveness and uptake of exposure therapy. The study aimed to test the feasibility of the consortium's big-team science approach and test the hypothesis that adding post-exposure processing focused on enhancing threat reappraisal would enhance the efficacy of a one-session large-group interoceptive exposure therapy protocol for reducing anxiety sensitivity.
Methods: The study involved a multi-site cluster-randomized controlled trial comparing exposure with post-processing (ENHANCED), exposure without post-processing (STANDARD), and a stress management intervention (CONTROL) in students with elevated anxiety sensitivity.

The paper presents new evidence collected in the last five years supporting the Words As social Tools proposal on abstract concepts. We discuss findings revolving around three central tenets. First, we show that-like concrete concepts-also abstract concepts evoke sensorimotor experiences, even if to a lower extent, and that they are linked to inner experiences (e.

The presentation of avoidant/restrictive food intake disorder (ARFID) characterized by fear of aversive consequences of eating (fear-ARFID) has both phenomenological and mechanistic similarities to panic disorder. In this narrative review, we propose a shared model of the pathogenesis of the two disorders, centered on interoceptive sensitivity as the key maintenance mechanism. We review the evidence that fear-ARFID, which involves restrictive eating motivated by a desire to avoid aversive events (e.

Background: Anorexia Nervosa (AN) is a severe Feeding and Eating Disorder (FED) that is more prevalent in females, often manifesting during adolescence. Recent research highlights an elevated presence of comorbid Autism Spectrum Disorder (ASD) traits among individuals with AN, with specific expressions in females accounting for sensorial and interoceptive experiences. This study retrospectively explores the association between ASD traits, eating symptomatology, and interoceptive deficits in Italian female adolescents with AN.

Morning-time heart attacks are associated with an ablation in the sleep-time dip in blood pressure, the mechanism of which is unknown. The epigenetic changes are the hallmark of sleep and circadian clock disruption and homocystinuria (HHcy). The homocystinuria causes ablation in the dip in blood pressure during sleep.
