What is the difference between a closed head injury and a mild traumatic brain injury?

A closed head injury occurs when the skull is impacted by a blunt object or is fractured by a sharp object. In contrast, a mild traumatic brain injury (MTBI) is a type of head trauma that involves the interruption of normal brain functioning, but in which the physical structures of the brain are not damaged. Closed head injuries are generally more severe and can cause physical damage within the skull, resulting in contusions, lacerations, and other injuries. These can lead to swelling of the brain, increased intracranial pressure, and a disruption of the blood-brain barrier. In some cases, closed head injuries can cause fractures and bleeding of the brain tissue. In comparison, MTBIs are less severe and generally involve a disruption of the normal functioning of the brain. This could include a period of confusion, disorientation, impaired memory, and concentration deficits. In some cases, a person who suffered an MTBI may also experience physical symptoms such as nausea, headache, dizziness, double vision, and/or ringing in the ears. Due to their less severe nature, mild traumatic brain injuries are typically easier to diagnose and can often be treated without surgery. Treatment usually involves rest and medication to reduce swelling and improve functioning of the brain. Additionally, physical, occupational, and/or speech therapy can be used to help the individual with any deficits that have resulted from the injury.
