Just reread the article and it triggered a memory. When I was at college doing the psychiatry module, we learned about many different disorders....and it was amazing how when we were learning about the behaviour of a disorder, we would suddenly see people demonstrating those behaviours all around us in the streets and shops. We brought this up in class and the lecturer said it was a common phenomenon....not that the world had suddenly become filled with people with mental health disorders but because once we knew what we were looking at, we noticed them. The same thing can happen with a doctor who has just done training on a specific illness or disability....its at the front of their consciousness and they find themselves considering it more as a possible diagnosis. The actual illness rate doesn't go up but the diagnosis rate does.
