Fight-or-Flight Seizures

I'm a speech-language pathologist.  Several years ago I worked with a child who was diagnosed as having Angelman syndrome, and she had temporal lobe seizures. The pediatric neurologist described her related behavior  as being  a fight-or-flight response.  Now I am working with a 15 year old boy with Down syndrome and autism.  He is exhibiting many of the same behaviors the other child did.  I need updated information on symptoms and signs associated with temporal lobe seizures, particularly the fight-or-flight response.
