Angie,

I may be off base (plus my brain is a bit slow this morning), but cortisol is responsible for maintaining your body’s energy systems - blood sugar being one of them.  Whenever we’ve gone to the ER or endo’s office for emergency treatment, they have always checked their blood sugar with the electrolytes.  It is very possible that low blood sugar was the cause of your son’s seizure.  I find CAH to constantly keep us on our toes!  We have 2 daughters (7 & 8 yrs old) both with sswcah.  I hope this helps or that one of the smart moms :)  will post and give a better explanation.  Blessings to you and your family
