Here's a new article I found that indicates patients who don't recover from PCS after only 3 months need to get their hormones tested:

Up until I read this just a few minutes ago, I was under the impression from other reading that patients should wait a year. This is a boon and will help people receive treatment sooner.

"New guidelines on neuroendocrine dysfunction (NED) were released in August 2012 by the Defense Centers of Excellence. NED can occur as a result of trauma to the underlying structures in the brain. The anterior pituitary gland is the most susceptible area. The disorder can mimic symptoms of mTBI or PTSD, producing sleep disturbances, fatigue, memory and concentration issues, and emotional or mood disturbances.

If a patient experiences the above symptoms for more than 3 months or has a new onset of these symptoms up to 36 months after a concussion, he or she would benefit from NED screening (Table 3)."
