GCS and FOUR score will be recorded during the primary assessment in the ER followed by 24 hours post presentation. The FOUR score and GCS will be compared to the Marshall classification to find out which one correlates with severity of injury better. Data regarding usage of anti platelets/anti coagulants prior to Traumatic brain injury will be collected. It will be compared to outcome to know if it interferes with outcome of TBI. GCS scoring includes eye opening, verbal and motor response for the assessment of severity of TBI. The primary outcomes will be measured using Glasgow outcome scale extended. Patients will be prospectively followed up and score will be recorded in Glasgow outcome scale extended (GOSE) at1 month and  3 month via telephone/face to face interview. Details collected includes data to analyze mortality and level of disability due to the TBI. GOSE 1 (dead), GOSE 2 (vegetative state), GOSE 3 (lower severe disability), GOSE 4 (upper severe disability), GOSE 5 (lower moderate disability), GOSE 6(upper moderate disability), GOSE 7 (lower good recovery), and GOSE 8 (upper good recovery). Our study tool will be a pre structured proforma and it consists clinical evaluations  and diagnostic part.
