Head injury represents a challenging issue for clinicians, biomechanical engineers and medico–legal experts ^(1).Predicting the outcome of Traumatic brain Injury(TBI) has been an enigma to clinicians especially neurosurgeons. This study aims to analyse the presenting complaints, Glasgow coma scale (GCS), types of injuries and their sensitivity, specificity, positive and negative predictive values. In this study, 183 paediatric cases, 2260 adults and 507 geriatric cases were analyzed. In adults and geriatric population , men were found to be have a higher incidence. In symptoms, vomiting was the commonest symptom in paediatric age group while Loss of consciousness was found to be a common symptom in other ages. Though all the symptoms had a high specificity, sensitivity was low. GCS was found to have a high sensitivity, specificity, positive and negative predictive values.
