The Cognitive Toll of Digital Overuse on Migraine in Young Adults

Migraine remains a major source of disability in young adults, and the rapid rise of digital overuse introduces a modern environmental burden that may worsen cognitive impact. Emerging evidence suggests that prolonged screen engagement interacts with core migraine mechanisms, such as cortical hyperexcitability, trigeminovascular activation, and circadian disruption, through factors including high-intensity blue light, sustained near-work posture, and, more controversially, radiofrequency electromagnetic fields. This editorial calls for future research that should determine how digital environments heighten migraine vulnerability by integrating lifestyle factors with objective digital-use patterns, including photic load and sleep disruption. Early priorities should include testing blue-light reduction or ergonomic strategies and developing digital biomarkers, while long-term neuroimaging studies should clarify how sustained screen exposure alters cortical and thalamocortical dynamics. Clinically, these insights call for routine assessment of digital behaviors and the adoption of targeted digital-hygiene interventions such as blue-light filters, dark mode, screen-time limits, optimized posture, brightness adjustment, and scheduled sensory breaks as essential components of migraine care in addition to the pharmacological treatment.
