Mild head injury (80% of cases) alterations (memory & attention) Most frequent TBI 5. in combination w/ 1-4, normal findings on traditional No loss of consciousness or brief neurodiagnostic tests (EEG< CT and period of altered consciousness but skull radiographs) no persistent focal neurological deficits 2. Moderate Head Injury (10%) Ill defined May have Subtle: Neuroanatomical Lesions Post-traumatic experience < 24 H Produced GCS score 9-12 Criteria (Medical College of West Virginia) Coma < 6H LOC ≤ 20 mins 3. Severe head injury Glasgow score 13 or higher Coma at least 6 H but regain capacity for conscious activity No neuro findings 50% No abnormality on CT scan, Skull Outcome determined by Glasgow X-Rays outcome scale GCS < 8; PTA ˃ 24 H Discharge from hospital within 48 H 4. Persistent Vegetative state Does not Regain Consciousness PTA < 1 H Based on recent studies a TBI is considered mild if it has the following characteristics: 1. Short Post-Traumatic Amnesia (
