The Centers for Disease Control and Prevention is warning of an accelerating mental health crisis among adolescents, with more than 4 in 10 teens reporting that they feel “persistently sad or hopeless,” and 1 in 5 saying they have contemplated suicide, according to the results of a survey published Thursday.

Dr. Karen Rogers, clinical psychologist at Children’s Hospital Los Angeles, joined “Your Morning” to discuss the growing mental health crisis among young people, potential warning signs and how to help.
