Diffuse Axonal Brain Injuries
A diffuse or multifocal traumatic brain injury affects a more widespread area of the brain. Acceleration/deceleration injuries caused by car accidents may result in diffuse brain damage. These injuries may be difficult to identify using imaging equipment like CT scans or MRIs because much of the damage occurs at the cellular level.
Motor vehicle accidents are a common cause of diffuse axonal injury (DAI). Some background information regarding the composition of the brain may be helpful to an understanding of DAI.
The human brain contains billions of nerve cells called neurons that allow the brain to function. A neuron consists of a cell body, projections from the cell body called dendrites, and a long nerve fiber called an axon.
It is the axon that provides interconnection and communication between neurons. With certain kinds of trauma, the brain’s axonal fibers are damaged as they are stretched and twisted through rotational forces that halt communication between different areas of the brain.
Unfortunately, the damage doesn’t always end with the initial injury to the axon. In the hours and days that follow, further brain damage can occur as injured neurons degenerate and release toxic biochemical cascades that impair nearby neurons that may not have been injured in the primary insult or trauma.

How does a person sustain a diffuse axonal injury? It can happen during a serious motor vehicle accident. The human brain, which is gelatin-like in consistency, is enclosed within a hard, bony skull. When a car is struck hard in the rear, the driver’s head may be thrown forward violently and may strike a stationary object such as a steering wheel.
When the skull moves forward rapidly and then stops suddenly after it hits the steering wheel, the brain moves forward and backward within the skull. However, unlike the skull, the brain, which is a soft substance, moves at a different rate of speed. This means that, as the brain moves forward, the skull may be moving backwards and the skull and the brain will strike each other.
Even worse, within the brain itself, one part of the brain may be heavier than another part of the brain. As a result, these parts also move at different speeds causing the affected parts of the brain to collide with each other. The multiple collisions may cause diffuse axonal shearing, contusion and edema (swelling of the brain). DAI can be devastating because the resultant brain damage may be widespread.
DAI is a major cause of loss of consciousness. In the most devastating cases, an injured victim may remain in a persistent vegetative state and never regain consciousness. In milder cases, manifestations include impaired cognitive function such as memory loss, visual loss, weakness on one side of the body, and inattentiveness.
