There may be a lesion inside of the brain that causes the seizure. There are numerous diseases that can cause damage to the brain itself. There are also other diseases that do not directly cause lesions to form in the brain, but instead change the metabolism of the brain or change the way that electricity flows through the cells of the brain.
