IGF1 and concussion: In this study, we aimed to investigate the association between serum IGF-1 levels and the prognosis of patients with mTBI, utilizing the Wisconsin Card Sorting Test (WCST) to evaluate the cognitive status of patients.13 The WCST is a widely accepted neuropsychological assessment tool that evaluates executive functions, including cognitive flexibility, problem solving, and abstract reasoning.13–16 By incorporating the WCST, we sought to gain insights into the cognitive aspects of recovery and their potential relationship with IGF-1 levels.
