Only on the "CBS This Morning" podcast, CBS News chief medical correspondent Dr. Jonathan LaPook talks with New York University's Dr. Michael Lindsey about his recent study that found self-reported suicide attempts by black teenagers have been rising over the past three decades. Dr. Lindsey, the executive director of the McSilver Institute for Poverty Policy and Research at NYU, discusses the findings and explains the consequences of black youth not receiving adequate treatment for mental illness. Actress Gloria Reuben, who starred in "E.R.," also joins the conversation to share the impact of losing her younger brother to suicide. Next month, she is publishing a book, "My Brothers' Keeper: Two Brothers. Loved. And Lost." Dr. Lindsey and Reuben share the importance of breaking down the stigma surrounding mental illness in the black community.
