A 45-year-old CMV driver presents for recertification.
He discloses a history of a single episode of major depressive disorder, which was considered severe and involved suicidal ideation, but no attempt.
He has been successfully treated by a psychiatrist, is no longer on medication, and reports being completely symptom-free.
