I would devise a training class and present it to management. Tell them you can present the information and it will cover various mental illness to help keep everyone up to speed on the latest information. Also, it will be able to be recorded as a training program. Maybe even have some of the other people put on trainings as well. Get them all involved. It helps the organization and will get them the correct information without it seeming like you are being nitpicky and correcting their ignorance.
