I agree with your concern on p. 7 of the Sept./Oct. issue of Neurology Now, but I also think you are preaching to the congregation.
It's the professionals staffing emergency departments (ED) who need to be educated. Some ED doctors make light of TIAs—you are made to feel it was a waste of time coming. Three times I took my sister to the ED over the course of a year. Once she was told to come back if it happened again. Once she was told don't come to the ER because nothing could be done.
Then when she had the stroke and was brought to the ED by ambulance (and we all are told you get quick attention if you come by ambulance), she was put in a wheelchair and dumped in the waiting room. I was the one who got hold of the nurse to tell her my sister's speech was getting worse.
