Biomarkers for Anorexia nervosa
Dr. med. Hubertus Himmerich, London, UK; Reader in Eating Disorders
Highlighting innovative sections of the consensus paper, the keynote lecture will specifically cover genetic risk factors for the development of AN (e.g., GWAS results, genetic correlations, polygenic risk scores), genes identified as being differentially methylated in AN in EWAS studies (e.g., NR1H3, TNXB, SYNJ2, PRDM16, HDAC4), brain imaging results that have been interpreted as biological factors perpetuating AN (e.g., reduced grey matter and functional connectivity), endocrine changes leading to adverse physical and behavioural consequences (e.g., leptin) and physical health risk and refeeding markers. Hubertus Himmerich will also explain the relevance of these research findings for currently tested novel pharmacological treatments (e.g., metreleptin, psilocybin, ketamine) and for future psychological and pharmacological treatments
Interpersonal Synchrony in the Transmission of Psychopathology: Mechanisms, Risks, and Clinical Opportunities
Prof. Dr. rer. nat. Kerstin Konrad, Aachen and Jülich, Germany, Professor of Clinical Neuropsychology
From the play of a baby and parent to coordinated dancing, singing in a choir, or the la-ola wave in stadiums, our social behaviors are tightly synchronized with those of other people. This talk will introduce the concept and theories of interpersonal synchrony, examining how our actions, emotions, physiology, and neural states align with those of others in everyday interactions. We will review the current evidence for a causal role of interpersonal neural synchrony, discuss candidate neurobiological mechanisms—including shared neural circuits, neurotransmitter systems, mirror processes, and oscillatory coupling—and highlight methodological challenges in capturing the dynamic, bidirectional nature of social interaction.
In clinical contexts, interpersonal synchrony may be particularly important in the intergenerational transmission of psychopathology. We will explore how early alignment and misalignment in affective, physiological, and attentional processes shape stress reactivity, emotion regulation, and vulnerability across development. Synchrony also plays a role in peer influence, including emotional contagion, reinforcement of maladaptive behaviors, and the spread of risk processes within adolescent social networks. This perspective suggests that healthy development requires not only the capacity to connect and “be in sync,” but also the ability to move out of synchrony to maintain autonomy and flexible self-regulation.
We will further discuss how synchrony-based mechanisms may contribute to the transmission of body-related concerns, meal-time behaviors, or restrictive norms within families and peer groups. Finally, the role of interpersonal synchrony in therapist–patient relationships will be considered, including innovative synchrony-informed therapeutic approaches.
By understanding and modulating interpersonal synchrony, we can move toward novel pathways for strengthening social connectedness, enhancing emotion regulation, and improving clinical outcomes.”
