This is because reaction time and brain processing are not normal. During this time people are more likely to have another injury if engaged in sport activities. ![]() Loss of consciousness and nausea at the time of injury are signs that rotational forces have occurred and can lead to prolonged recovery from injury.Ĭurrent research on athletes shows that nerve signals in the brain are disrupted for 30 days after a single concussion. If the body is traveling forward or facing forward in a still position and a force occurs off center, the brain sustains a rotational shear force, which causes more trauma to brain structures than only linear forces and therefore can result in a more severe TBI. There is typically a rotational force, as would occur if one were struck on the right or left side of the forehead. Rarely does an accident of this nature occur in a true head-on or forward/backward direction. These events all cause quick deceleration of the head and shifting of delicate brain tissue inside the skull. For example, whiplash injuries often occur during motor vehicle accidents and cause a concussion. This can occur in dancers and gymnasts due to rapid movement, or during an auto accident where there appears to be no head trauma. A quick acceleration/deceleration of the head with no contact to any surface.An object hits the head, such as a ball or stick during sports, or as a result of human collision.Common examples include a fall where the head hits the ground or an object, or hitting the head on an object during an auto accident. ![]() The Vestibular traumatic brain injury (tbi) Connection What Happens to the Brain and Vestibular System after a Traumatic Brain Injury?Ī traumatic brain injury can occur under the following conditions:
