Identifying a biomarker for a psychological condition, particularly one like schizophrenia which is hugely disruptive for individuals affected and has a seemingly random onset around early adulthood, is significant in its own right even if it doesn’t lead to a pharmaceutical intervention. It could help identify new risk factors, potential non-pharmaceutical interventions like life style changes, and maybe even identify people who are at risk of developing schizophrenia and preparing them for its onset before their first hallucination and avoiding a downward spiral.
