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.

A head injury can cause seizures as can illicit drug use, withdrawal from certain prescription drugs, strokes, metabolic disturbances and other medical conditions. A seizure is a manifestation of a brain problem associated with sudden, abnormal electrical activity in the brain. Most seizures fall into one of two categories:
Generalized seizures are caused by abnormal activity on both sides of the brain. Generalized seizures are categorized in subgroups: absence, myoclonic, clonic, tonic, tonic-clonic, and atonic seizures. A person loses consciousness during a generalized seizure.
Focal or partial seizures occur in only one part of the brain. Focal seizures fall into two subgroups. How they are categorized depends on the degree to which a person’s consciousness is affected. A simple partial seizure does not involve loss of consciousness whereas a complex partial seizure does.
Symptoms associated with seizures are varied and depend on the part of the brain affected. Most seizures cause loss of awareness. Many involve twitching or shaking of the body. Some present with jerking movements of the head and body as well as drooling, biting of the tongue and incontinence. Other types of seizures have more subtle symptoms like staring spells or short term changes in vision or feeling.
Specific symptoms that may occur at the onset of a seizure include:
- Alteration in consciousness associated with temporary loss of memory
- Alteration in emotion with a feeling such as fear, panic, joy, confusion
- Alteration in sensation such as numbness spreading over a part of the body (for example: an arm or leg)
- Alteration in vision such as “seeing stars” or sparkles
- Sudden, involuntary contraction of muscle groups often causing a person to fall
- Muscle twitching in the arms or legs
- Tension or tightening of the muscles causing the body or body parts to twist
- Smelling an odd, unpleasant odor
Usually, seizures are brief occurrences and last only a minute or two. To diagnose a seizure disorder, a physician may order blood tests, CAT scan imaging, magnetic resonance imaging (MRI), and/or EEGs which record the brain’s electrical activity. Anticonvulsant medication is a common treatment for a seizure disorder.
