The Question
What are the characteristics of diffuse axonal brain injury?
Past Studies
Past Studies show that 40% to 50% of traumatic brain injuries requiring hospital admission
This Study
This study consisted of a review of the published research and literature related to
Who May Be Affected By These Finding
Individuals with diffuse axonal injuries, healthcare providers, researchers
Caveats
The researchers indicate that there is evidence that the type of cellular injury that takes place in DAI, may involve different receptors and brain chemical pathways than do other types of brain injury. The researchers suggest that this may explain the lack of success for medication trials for brain injury.
Bottom Line
The researchers conclude that the name “diffuse axonal injury” is an error. It is not a widespread injury to the whole brain but instead an injury that occurs just in particular locations. The majority of individuals with DAI appear to experience difficulties with memory and rapid mental processing skills.
