The University of Kansas is offering a military mental health first aid course. The course is designed to help active military members, veterans, their families and people who work with them recognize and respond to signs of mental illness. The free class is planned for Saturday at the Lawrence campus. Participants will receive certification as a Mental Health First Aider. Organizers say the Mental Health First Aid program has trained more than 300,000 persons since its origin in 2008. A military-specific program began in April 2014 and works to help people recognize issues common to many veterans, such as post-traumatic stress disorder, anxiety, depression and substance abuse.
