Traumatic Brain Injuries (TBI) or head injuries are injuries or trauma to the scalp and or brain caused by an outside force, usually a violent blow or collision to the head by accident or deliberate attack. It can also be called be craniocerebral trauma. TBI are examples of acquired, non-degenerative assault to the brain from an external mechanical force, causing impairment of brain functions, with or without alteration to the mental state or consciousness of the victim. This paper provides a synopsis of the epidemiology and patterns of associated injuries in mild and moderate head injuries in literature. Mild and moderate head injuries were selected because they are by far commoner than severe head injuries and the outcomes are widely varied than severe head injuries. Traumatic brain injury is a global and public health problem, which in the coming years, might be the leading cause of death in Africa. High incidence is found among the adolescent and the adult age group and gender-wise, it is common among the males of the same age group. Likewise, the provision of an ambulance system and standard healthcare facilities to manage 18 patients with a traumatic brain injury can not be overemphasized.
