Traumatic Brain Injury
Traumatic brain injury (also known as a TBI) is not usually caused by one event but by a series of events. These are usually classified as primary and secondary events.
– The primary event is direct damage to the brain at the point of impact.
– The secondary event refers to the complications that may arise in the minutes, hours and days following the impact – these are due to a lack of oxygen and the reaction of the brain to the initial injury.
It is important to remember that the injuries described cover a range of possibilities. They will not apply to everyone who has sustained a brain injury.
