I suffered a concussion about 6 months ago, and have been experiencing PCS symptoms ever since, primarily headaches and some cognitive difficulties.

I have been making steady progress, and my symptoms have been gradually subsiding, although I still seem to have a certain way left to go.

I have seen a neurologist, and she assured me that after 6 months, she was certain that my symptoms were no longer related to physical injury, but were psychological at this point, a mild form of PTSD. She recommended a psychologist and encouraged me to push my limits more. She also said that once I overcame the injury, I would not see any cognitive/IQ deficit or lingering symptoms.

This is great news to me, as I was very worried about residual cognitive effects and physical damage. I wanted to ask if this was a common pattern of recovery, and if there's any chance that some it what I'm experiencing could still be physical?
