Head injury is the leading neurological reason for despondency and fatality, particularly influencing the youngsters. 85% to 90% are mild or moderate TBI. Objective: To find prevalence of traumatic brain injuries on computed tomography and that of severity classification from mild to severe grade. Material and Methods: 100 patients with history of head trauma were evaluated in this study, which came to emergency department of Public sector. GCS was taken and all were referred to CT. Noncontrast CT of brain was performed with slice thickness of 3mm from skull base to vertex. And analysis was done using (SPSS) Statistical Package for the Social Sciences version 21. Results: Of 100 TBI patients, men composed 66% and women 34%. Falls (38%), violence (2%) and other causes (5%) all collectively cause fewer traumas than RTA (55%) specifically in patients of age group 16-26 years. Different traumatic brain injuries were noted including EDH (22%), IPH (23%), SAH (9%), SDH (27%), Contusion (4%) and infarction (15%). Noteworthy, most of the brain injuries were observed as mild TBI in 65% of cases accounting for more than moderate (21%) and severe TBI (14%). Conclusion: The study concludes that 65% of patients who acquired head trauma had mild TBI while remaining 21% and 14% consumed moderate and severe TBI respectively. Subdural and intraparenchymal hemorrhages are most frequent type of diagnosis in TBI.
