Transformations in Early Childhood Social Bonds During the COVID-19 Pandemic and the Rise in Autism Diagnoses

The COVID-19 pandemic brought about abrupt and large-scale disruptions in early relational environments due to mandatory lockdowns, closure of educational and therapeutic institutions, and the suspension of community-based interactions. Notably, during this same period, a significant increase in autism spectrum disorder (ASD) diagnoses was observed in several countries— including Argentina—even at times when access to healthcare services was severely restricted. This trend is particularly paradoxical given the absence of comprehensive data on consultation rates and the concurrent decline in MMR vaccination coverage, thereby weakening vaccine-related etiological claims. This study undertakes a critical examination of this convergence, without positing a direct causal relationship, by interrogating whether the structural alteration of early intersubjective experiences may have contributed to the emergence or amplification of behaviors later codified within the diagnostic boundaries of ASD. The hypothesis advanced is not etiological but ecological: it explores the possibility that sustained disruptions in symbolic mediation, affective co-regulation, and relational consistency in early childhood constituted conditions of developmental vulnerability. A documentary design based on secondary sources was employed. Quantitative data were drawn from public health records issued by the Argentine Ministry of Health, the National Disability Agency (ANDIS), the Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO), and UNICEF (2018–2023). These were analyzed in conjunction with theoretical frameworks from developmental psychology, psychoanalytic theory, and public health, emphasizing concepts such as early symbolic structuring, intersubjective deprivation, and epistemic trust. Findings indicate a sustained increase in ASD diagnoses during and after lockdown periods, without statistical correlation to vaccination trends. Qualitative literature consistently reports increased social withdrawal, delays in language acquisition, diminished symbolic play, overexposure to screens, and elevated caregiver stress—factors that intersect with current diagnostic criteria but may reflect contextual and relational stressors rather than intrinsic neurodevelopmental alteration. The study underscores the need to reconsider diagnostic frameworks and public health approaches through a relational-developmental lens in the face of large-scale social disruptions.
