Does anyone else have anxiety problems because of head trauma?

[RockRaven]

5. A close relative of mine suffered a head injury while cycling...

struck from behind by a driver who drifted outside the white line on a windy road, serious concussion and some bad road rash but no fractures, abdominal injuries or long-term hospitalization. They experienced a period of anxiety and panic attacks -- including one bad enough to precipitate an ER visit within the first month after the injury -- but have since progressed beyond it. It was bad for a few months and slowly receded over a year or two. They did not develop caffeine sensitivity as far as I'm aware, but maybe they just didn't share that with me. In any case, they definitely imbibe in regular coffee on a regular basis nowadays (5-10 years later).

I'm sorry for what you're going through.
