I just heard about it and just researching. I have a grandson that we are raising and one of his teachers in middle school mentioned that she was wondering if he may have this. He does have petit mal seizures and speaks out of turn in his classes. He gets onto a subject and continues to repeat something over and over again. We also have an adopted son who is 36 years old and will talk to himself continuously. If we ask him who he is talking to then he quiets down or goes to another room to continue his conversation.
