Аннотация: Cerebral small vessel disease (SVD) is a major cause of cognitive impairment inelderly people. While most research focuses on the role of the classical vascular riskfactors in SVD, a description of the psychophysiological mechanisms leading to theage-related brain damage may open new possibilities for prophylaxis. In the currentstudy, we evaluated the associations between emotional abilities, interoception, andage-related vascular white matter degeneration. The work was influenced, first, bymultiple studies recognizing alexithymia as a cardiovascular risk factor; second, bytheories of emotions linking body's allostasis and emotional regulation; and third,by neuroimaging data highlighting the shared role of the insular cortex in interoceptiveand emotional processing. In a sample of older female adults (N = 30), weperformed the Mayer–Salovey–Caruso Emotional Intelligence Test, functional MRIusing the heartbeat detection task, and evaluation of white matter microstructuralintegrity using diffusion weighted imaging. The ability to understand and analyzeemotions—one of the four components of emotional intelligence—was found to beassociated with higher interoception-related activation of the right anterior insulaand preserved white matter microstructure. We interpret these results in light of theconcept of Embodied Predictive Interoception Coding, which proposes that emotionalprocessing, interoception, and allostasis (antecedent top-down regulation ofthe body's internal milieu) may rely on the shared neural mechanisms of predictivecoding. The study demonstrates feasibility of the investigation of cerebrovasculardiseases form a psychophysiological perspective and calls for future research.
