illness or disease are getting any help at all. >> are we equipped to diagnose them and get them treatment? i mean, we're looking at health care for children about to be cut. can we help them if we diagnose them? >> reporter: well, listen, that's a good question. there are very few child psychiatrists in this country. very few access points. schools are now taking this up. we're going to be in future episodes talking in news stories talking about what schools can and are doing to help diagnose and get help for kids. but it's difficult. and one of difficulties is the parents are often ashamed and don't know what to do. so, knowing when you have a teenager who is going through usual teenage angst and a teenager that has a real problem that needs to be diagnosed and treated, parents aren't so sure so we're going to give

tips. >> wonderful. this is something we need to be talking about, and especially the shame. because we do something here called changing minds. we need people to get over the stigma of this because you don't treat this early, and this can compound itself over time and over time, and become a real, real crisis for the individuals and for the family. >> reporter: and for society. kids drop out of school. kids end up in prison. there is a direct pipeline to all of this. we hope we're going to open some eyes with this series over the next several months. >> cynthia, we look forward to this series. thank you for doing this. >> reporter: we'll be in touch. thanks so much. >> the nightly news series is called "one in five kids at risk." it kicks off tonight with more on what's led to the increase in these disorders, and some of the innovative programs created to deal with them. some of the solutions. that's nbc nightly news immediately following news4 at 6:00. you don't hear about too
