Your post is confusing.

You said<If so, why do they say PCS prognosis is excellent yet pituitary not so much? >

Please elaborate.

From what I understand, concussion can cause pituitary damage thus hormone malfunction. Many with PCS benefit from broad hormone testing so that hormone replacement can be done.

I take DHEA to help with hormone regulation. I am waiting for a recent DHEA blood test to see how my DHEA levels are.

The common hormones tested for PCS are all the thyroid tests (T3, T4, TSH) testosterone, progesterone, estradiol, DHEA, and DHT (dihydrotestosterone)
