I need your input
I'm planning on publishing some booklets next year. They'll be full-colour booklets with artwork. The focus will be on the symptoms people can expect after brain injury, but I'm particularly interested in the effects we were never informed about.
As an example, I posted something on Facebook about aphantasia - the loss of visual memory/imagination. Somebody commented "I didn't know that was a symptom of my brain injury! I thought I was going mad!"
Slightly different but related: I only found out a few months ago that I'd sustained a brain injury in 2005. The factor that really pinpointed it was an absurdly specific visual problem that I read about in Clark Elliott's book, The Ghost In My Brain. I can find nothing online about this particular problem. Something is definitely wrong when vital information is so buried.
So which symptoms were you surprised by? Bonus points if you were told "That can't be happening" or "That must be psychological".
