This study investigates biochemical alterations in patients recovering from COVID-19, with a particular emphasis on those experiencing persistent neurological symptoms. We compared oxidative stress markers and other biochemical indicators in post-COVID-19 individuals with those in a control group without a history of severe acute respiratory syndrome coronavirus 2 infection. The findings revealed significant shifts in oxidative and inflammatory biomarkers, especially in patients reporting neurological complaints. These alterations may underlie the persistence of such symptoms and suggest potential targets for future therapeutic interventions and diagnostic strategies.
