The American Academy of Pediatrics is calling for routine depression checks in kids starting at age 12. There has been a sharp increase in teens feeling lonely, anxious, and depressed, and psychologist Dr. Jean Twenge says "this generation of young people is on the verge of the most severe mental health crisis in decades." Research shows right now that 2 out of 3 teens go undiagnosed with depression and fail to receive any kind of care, according to the American Academy of Pediatrics. The new guidelines also encourage pediatricians to talk with young people alone, and talk separately with caregivers. Experts say identifying mental health issues doesn't just fall on medical professionals, but starts with conversations at home.
