Thanks everyone. I know that it is generally not an emergency, and I know what to do. However, after she has a fit (I thought "fit" was British, "seizure" was American), she is disoriented, says strange things, doesn't know who or where she is for a while, and later has no memory of anything that happened during that time. She usually has her husband come and take her home so she can sleep it off. On a train we are trapped.
