“With the identification of biological markers, distinctions between syndromes like PANS and PANDAS may become clinically obsolete, shifting focus to underlying mechanisms rather than clinical presentation.” The authors argue that current labels like PANS and PANDAS are largely symptom-based frameworks that exist because we lack definitive biological tests. As research identifies reliable biomarkers such as immune signatures, autoantibodies, or inflammatory pathways, these distinctions may become less clinically relevant. Instead of categorizing patients by how symptoms present or which trigger is suspected, diagnosis and treatment could shift toward the underlying biological mechanisms driving illness, allowing for more precise, mechanism-based care rather than reliance on descriptive clinical syndromes.
- EMTICS (European Multicentre Tics in Children Studies) is a large longitudinal study designed to examine environmental risk factors for tic disorders, not to diagnose or test PANS or PANDAS which was not designed, powered, or structured to evaluate PANS/PANDAS, so using it to dismiss these conditions is methodologically incorrect.
- EMTICS did not systematically assess PANS/PANDAS clinical criteria or timing of infections relative to symptom changes.
