Neural correlates of altered interoception in depressive and anxiety disorders: a systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundInteroceptive dysfunction, the impaired sensing and interpretation of internal bodily states, has emerged as a potential transdiagnostic feature across several psychiatric conditions, particularly depressive and anxiety disorders. Despite their high comorbidity, it remains unclear whether these conditions are associated with similar or distinct alterations in brain regions underlying this process. To clarify this, we conducted a systematic review and meta-analysis of functional magnetic resonance imaging studies examining interoceptive processing in depressive and anxiety disorders.
methodsUsing a pre-registered protocol (registration number: CRD42024579900), we conducted systematic searches across five databases: PsycINFO, EMBASE, PubMed, Scopus, and Web of Science. Our initial search yielded 315 unique studies. After applying our inclusion criteria, we identified 11 relevant studies with a total of 659 participants (269 healthy controls and 390 clinical participants).
resultsOur systematic review and meta-analysis revealed significantly reduced activation in the right dorsal mid-insula and left posterior insula during interoceptive tasks in individuals with major depressive disorder. Interestingly, no significant effects were observed for anxiety disorders or the combined sample compared with healthy controls. Qualitative synthesis suggested potential insula hyperactivation in anxiety, aligning with theories of interoceptive hypervigilance.
conclusionThese findings support models of allostatic dysfunction in depressive and anxiety disorders, highlighting the insula’s role in interpreting bodily signals. Clinically, this underscores the potential of interoception-focused interventions to recalibrate insula processing and alleviate symptoms. Further research in anxiety disorders with reduced methodological heterogeneity would aid in clarifying the effects suggested by the qualitative synthesis.
