Abstract
BACKGROUND: Due to the very high and increasing prevalence, essential complications, and risk factors for psychiatric disorders, it is necessary to introduce screening tests for diagnosing and predicting mild traumatic brain injury (mTBI) prognosis. MATERIALS AND METHODS: After completing the consent form and recording information and examination findings of patients with mild trauma, venous blood samples were taken from these patients. The samples were measured by observing the cold chain. After 3 months from mTBI, the post concussion symptoms questionnaire (PCSQ) and the short form 36 (SF-36) questionnaire for physical and mental evaluations were performed. Statistical tests analyzed the relationship between different variables and serum Creatine kinase BB (CKBB) levels. RESULTS: Statistic analyses showed no relation between CKBB level of serum and age, gender, level of consciousness, PCSQ, and SF 36 scale, and the interval between trauma and arrival to the hospital. Further, there is a significant correlation between CK-BB levels and intracranial damage based on Fisher's exact test. CONCLUSION: This study and following more significant considerations can introduce a serum-based biomarker panel that can accurately differentiate patients with complicated mTBI from those with uncomplicated.
