The above post is correct. This is the cause of my epilepsy too. The scar left in my brain from very high fever as an infant is an area of epileptogenic activity since the neurons in the scar try to work and misfire. Think of a sca on your skin. It protects the body and trys to do the job it was meant to, but it is not exact anymore due to the damage it suffered. Same principle as the sclerotic area in the brain. Both examples are sclerotic. The area in my brain was small at first but it misfired occasionally which results in seizures. Over time, it can worsen if not stopped. The hippocampus is an area of the brain behind the temporal lobe that is many times one of the areas affected in epilepsy. Very epileptogenic. Very common too. Epilepsy from this cause or with this dignosis of mesial hippocampal/temporal sclerosis has the best prognosis from surgery. I had surgery 10 years ago and would do it again if needed! Great decision. Tattoo
