The best you could do to see how CAH can affect behaviour is check out research into Cushings and then at the opposite end of the extreme, anabolic steroid abusers.  They are the only ones that come close to what our kids go through when under treated.  I know a few doing steroids and they ALL admit it affects their mood, and temperament, let alone have that combination with low cortisol levels.  One guy over did some and it’s shut down his test production and it will take some time to come right again.  He is very depressed and such now and no libido.  This is after withdrawing from something like tribulis which is a herb and raises LH which then raises your own natural test levels.  I find it interesting to research into actually.  I can give you some support and we can try to find some info on it together if you like to supply to the school.  I may email you later as we’re school holidays here and I’ve been quite busy and will be for two weeks, but my son was suspended from school year before last because teachers handled the situation wrongly and I can pass on info to you about that later.  Off out for an appointment at the mo.  :)
