Are we overmedicating our kids? That’s the question of the hour. More specifically, it’s the question of the 9 o’clock hour this Sunday when Rona Renner’s “Childhood Matters” show looks at childhood psychiatric drug use. Interesting topic, no? Rona’s panel includes Dr. Glen Elliott, chief psychiatrist at the Children’s Health Council and author of “Medicating Young Minds,” and Walnut Creek’s own Dr. Lawrence Diller, behavioral pediatrician and author of “Running on Ritalin” and “The Last Normal Child.” Tune in on 98.1 KISS-FM or 105.1 KOCN-FM.
