J, I have a friend who is a tbi survivor yet does extremely well, but 10 yr.s after her crash/tbi, she started having sezures. Some pretty severe. The Docs still cannot detect what is causing them. She has undergone numerous testing with no answers.
She no longer drives because of the risk of having an unexpected sezure. She has been to several specialist. Mayo Clinic included.
My oldest boy has them, though it has been over a year since his last one. He had many tests, they found that he has abnormalities in his right frontal lobe the drs said was most likely cause by a fall he took as a toddler.
Meds won't work because of where it is located in the brain. It's not eplipesy so there is nothing we can do, but deal with them as they happen. Medications didn't do anything but make him sick.
The major trigger for him is lack of sleep, he had sleep apnea and had his tonsils and adeniods removed a couple of years ago. Since then he's only had two seizures.
