Previous posts on this blog have discussed the various ways in which an accident can lead to a traumatic brain injury.
After the brain is bruised in an automobile accident or other traumatic brain injury, the afflicted area of the brain will begin to heal. The body does this by producing scar tissue. The brain-scarring process can take many months, which is why the two most likely times a client, who has sufferred a head or brain injury, would experience a seizure is: (a) within a few hours of the traumatic brain injury; and (b) 10-12 months after the traumatic brain injury.
As in the rest of your body – with time – scars begin to harden. Unfortunately, this scarring process may stretch, press or irritate neurons immediately surrounding the scar. These irritations may interrupt normal functioning brain activity and lead to improper neuron firing. Remember, our brain’s neurons are interconnected with billions of other neurons, so when one small group of brain cells/neurons are irritated and act abnormally, it can affect other areas of the brain. For example, if the brain area that controls your left arm functions improperly – your left arm may begin to shake uncontrollably. If that irritation in the left arm area of the brain causes another area of the brain to become irritated, those neurons may too begin to fire uncontrollably causing that portion of the body to function improperly as well (and this pattern can spread to many different brain areas). Some anti-seizure medications work by simply slowing down the neuron-firing rates throughout the brain (which would include the afflicted area).
