Interoceptive alterations in post-stroke individuals: A comparative cross-sectional study. International Journal of Stroke, 20(1), pp. 315-316.1747-49301747-4949https://hdl.handle.net/20.500.13055/1284Background and Aims: Interoception refers to the complex neuro physiological process of sensing, integrating, and modeling visceral and somatic inputs to generate real-time internal state monitoring which is crucial for homeostasis and adaptive cognitive-emotional responses. Within the framework of the allostatic interoception model, this internal sensing system not only reacts to current physiological demands but also predicts and prepares for anticipated needs. Discrepancies between pre dicted and actual interoceptive signals may cause allostatic overload, dis rupting neural signalling. So far, very few studies have investigated whether stroke impairs interoceptive networks and how these impairments are associated with cognitive and motor functions. This study, therefore, aimed to investigate interoceptive capacity in post-stoke individuals. Methods: Forty stroke patients with Mini-Mental Test scores of >25 were compared with forty healthy controls with similar age and sex dis tribution. Interoceptive dimensions were assessed through Heartbeat Detection Task for interoceptive accuracy, Interoceptive Sensory Scale for subjective sensitivity, and Toronto Alexithymia Scale for interoceptive awareness. Cognitive performance was evaluated with Trail-Making Test, while motor functioning was assessed with Fugl-Meyer Motor Scale. Results: demonstrated significantly reduced interoceptive accuracy, sen sitivity and elevated alexithymia scores in the stroke group compared to controls (p=0.018, p=0.043, p=0.038 respectively). No significant associa tion was observed between interoception and motor performance. However, interoceptive accuracy was positively correlated with cognitive function (r=0.248, p=0.037). Conclusions: Our findings indicate that stroke-related neurophysiologi cal alterations may deteriorate interoceptive function. Incorporating interoceptive assessments and targeted interventions into clinical reha bilitation may improve recovery outcomes. Further research is needed to clarify the contribution of interoceptive dysfunction to post-stroke cogni tive and emotional impairments (versus SNF) care was consistently associated with higher HT and decreased odds of mortality and readmission (Table 2). IRF (versus SNF) was associated with higher mean difference in HT percentage ranging from 21% to 23% in PS matched cohorts, IPTW analyses generated more modest estimates of mean HT difference (10.6%).eninfo:eu-repo/semantics/openAccessConference Object201315316Q1WOS:001635827300735Q1
