Comparison of EEG and QEEG findings by MRI imaging in diagnosis and prognosis in Mild Traumatic Brain injury

Abstract

The aim of this study is to comparison of EEG and QEEG findings by MRI imaging in diagnosis and prognosis in Mild Traumatic Brain injury. Materials and Methods: In this cross-sectional study, the statistical population included all patients with Mild Traumatic Brain Injury in Imam Reza Hospital in Tabriz, whether hospitalized or non-hospitalized, who referred to the trauma ward in 2020. The final sample size was 30 cases. Sampling was simple and availability. Demographic information of patients was extracted from the files and Database of Imam Reza Hospital. Simultaneously with the patient entering the study, in order to obtain informed consent from the patients, the executor of the project explained and informed the patient about the purpose of the research and its various aspects and answered the patient's questions. EEG and QEEG were taken from patients and compared with imaging (MRI) and patient clinical findings. Results: In this study, the mean (standard deviation) age of the subjects was 43.23 (±20.5) years. Based on the diagnostic findings, 10 cases (33.3%) of the subjects in this study with MRI, 21 cases (70.0%) with EEG and 30 cases (100.0%) with QEEG were diagnosed abnormal. There was no statistically significant relationship between MRI findings and EEG findings (P = 0.675). Also, based on clinical findings, the most reported disorders were memory impairment with 21 cases (70.0%), neuromotor impairment with 20 cases (66.7%) and sleep disorders with 14 cases (46.7%), respectively. Of all the Absolute waves in the anterior, central and posterior regions in the subjects, in most regions the alpha 2 wave with beta 1, beta 2, and beta 3 waves, and in all regions, beta 1 wave with beta 2 and beta 3 waves and in all regions, beta 2 wave with beta 3 wave had a significant correlation (P <0.05). Also, among all the Relative Power waves in the anterior, central and posterior regions in the subjects, in most regions the delta wave with theta wave and in all regions with alpha 1 and alpha 2 waves, theta wave in all regions with beta 2 and beta 3 waves, alpha 1 wave in all regions with alpha 2 wave and in most regions with beta 1 and beta 2 waves, alpha 2 wave in all regions with beta 1, beta 2 and beta 3 waves, beta 1 in all regions with beta 2 and beta 3 waves and beta 2 wave in all regions with beta 3 wave had a significant correlation (P <0.05).
