powerblackwolf,

I actually coined the term Concussion Anxiety Syndrome many years ago as I tried to help people on this forum. I have promoted the term to experts in hopes somebody would do some study. Others have slowly started to consider CAS as an issue, whether they use the term or not.

One study does show that 80% of people who experience prolonged struggles have a pre-existing history of anxiety and/or depression.


The idea that concussions combine to become easier to sustain was likely a result of the many people who develop symptoms from lesser bumps, whether those bumps are whiplash, anxiety triggers, or startles/annoyances. All of these non-concussions can cause similar symptoms
