“Seizures may develop immediately after an injury to the brain or may develop in delayed fashion, showing up months or years after the initial trauma. Generally speaking, the risk of post traumatic seizures is related to the severity of the injury — the greater the injury, the higher the risk of developing seizures. Even mild to moderate injuries can result in seizures.
There are many kinds of seizures and seizures are not an uncommon condition among persons without head injuries. It is thought that a head injury disrupts the pathways of the brain and that an epileptic seizure can be viewed as a sort of short-circuit of the brain’s electrical functioning. During the seizure the electrical fields in the brain are overloaded, resulting in seizures.
The most commonly seen seizures related to traumatic brain injury are “generalized” seizures, which are also called “Tonic-Clonic” or “Grand Mal” seizures.
Persons who have had head trauma are twelve times as likely as the general population to suffer seizures.
Approximately 57% of head injured individuals developed epilepsy within one-year of injury. Longer onset epilepsy beginning more than four years after the trauma occurs in 20% of patients who developed epilepsy.
It is estimated that 30% of all individuals suffering head trauma developed post-traumatic seizures and 80% of the time they occur within the first 24-months.”

My epilepsy occurred 2 years after falling and getting a concussion while snowboarding. Nobody told me it could happen but it did and now I have grand mals. My husband always asks me if I regret snowboarding now. It's hard to answer. Part of me says no. Part of me says yes. Hard one to answer.
It's interesting to see these statistics. I'm one of those people who has no definitive idea why I have seizures. I have had a number of MRIs over the years and they always come back normal. I was in a motorcycle accident about a year before the seizures started and had hit my head on the ground. I was wearing a helment and never lost consciousness, so I figured I would be OK. So, maybe it was the accident, maybe not. I'll never know for certain. But, the statistics here make a strong case for it being the head trauma.
I think for the rest of my life I will be confused how my seizures all of the sudden started. It started with the neurologists saying that the falls that I had, where I hit my head, was the reason for the seizures. These were bad falls where I hit my head on concrete, but it was over 20 years earlier. Once it was in the bottom of a swimming pool where I felt a shocking/electrical feeling up my body through my neck when it happened. It wasn't until they cut out an area of my brain that was discolored, that they gave a different reason for the seizures. After the section that was cut out and tested, I was told that the seizures were being caused by "Chronic Spinal Meningitis". I just have a hard to believing that. I still, years later, don't trust that is the whole reason. How could I have "chronic spinal meningitis" and never know it?? Would you go ahead and just believe that. I had read about the spinal meningitis, and everything I read said that you need to get to medical care immediately. I never did, never knowing I had it! I can look back at being really sick, like a bad flu, and wondering if it was related but.....I will never know. I still wonder then why did I have "chronic" meningitis? Does that mean I can still get it and cause more seizures??? I have not been told anything my the medical experts and wish they did so I don't have to continue wondering if if will return for the same reason. hmmmm, what do you think? laura
thank you for the information Phylis! I had both scarring from where the seizures were being recorded and it was a different area that has turned gray. Now, I do not think that all that gray part of the brain was taken out. I was about to say that if it is chronic Meningitis, does that mean I can see it again? I went two years without even getting a cold/runny nose after my TLS. Then.....about three months ago I was soooo sick with a flu with a very high temperature. I was so weak I could hardly walk. Now I wonder, if I was diagnosed with chronic spinal meningitis, was this it again?? I did not go in to see a doctor when I was sick. I still question the reasoning for my seizures before my TLS being from Chronic Spinal Meningitis. but then......what else started my seizures all of the sudden????
