Not surprisingly, a lot of the PCS symptoms mimic the symptoms of low hormone production. Because of this, without blood tests, it is difficult to discern between the cause coming from tbi or low hormones. If you are interested in pursuing this, find a good hormone specialist in your area and consult with them. Otherwise, you can always run a google search on symptoms of hypopiutitarism and see if you have any of those.
