Next up in the heat index, journalist lisaling has been diagnosed with attention deficit hyperactive at 40. And Mara schiavocampo has more. Reporter: On her show for the own network, reporter Lisa ling covers everything from criminal informants to exorcism. But this morning, she's breaking news about herself. While working on a new piece about the explosion of add diagnosises, she started to notice the symptoms sounded familiar. I'm like panicking, emotionally. Yeah, I know that feeling. Reporter: And was soon diagnosed with add herself. All while cameras were rolling. I do feel you meet the criteria for having attention deficit disorder. Reporter: She long-suspected something wasn't right. If I'm not working, my mind goes in every direction but where it's supposed to go. I've been like that since I was a kid. Reporter: She decided to find out once and for all, undergoing nerve-wracking tests on camera. I'm stressed out. Reporter: She does have add. While an estimated 15 million people are diagnosed with some form of the disorder, her diagnose at 40 is unusual. The average age is 7, but when she was young, awareness is not as common. Add is more accepted now than 10, 20 years ago. People don't think of add in an adult. It's tremendously good news to diagnose it, because it can dramatically change your life for the better. Your whole life can come into focus. Reporter: Ling releasing this statement overnight. While the diagnoses confirmed what I have always expected, I have more clarity. I had been fighting it and frustrated with the innablt to focus. Reporter: One reporter fig figuring it out. Mara schiavocampo. And bring in Richard Besser. He's back. Add earlier, add, the differences. It's the same thing. The preferred term is add. It's all the same thing. It's not surprising that an adult has add. Roughly 1 in 25 have it. But surprising it was diagnosed so late. Likely missed along the way. How do you know if in fact you should be checked for it, or if you're like so many of us, overburdened trying to juggle it all. That's the big challenge. Because everyone's going to perform better on their life on an add medicine. Everyone? Yes. And that's the problem. That's why a lot of kids end up on this to do better in school. You can focus on the medicine, but you may not have the disorder. People having trouble doing basic tasks in their life. Having trouble with their job staying focused, problems with relationships, problems at home. But it started in childhood. That's the key. You say it helps everyone with no side effects. No, that's the thing, there are side effects. These are very strong medications. And worries me that people go on the medications, and feel pressure because their live are so busy, cluttered. Ed eded aer roll being one of them, there's an addiction possibility. Before you go on the medicine, be evaluated by someone who knows what they're doing. They have specialty in this. When I have kids in the clinic, there's a series of questionnaires for the teachers, family, to see how they're questioning. And here as well, not just talking to the individual, but to their spouse or important, to their friends, to get a sense how they're focusing across their life. Is this something that's truly add, or someone who's too busy and needs to focus down? Having a diagnose doesn't mean you need a medicine. We were hearing the story last week, the woman who won the Tony your she had the outlet. There are behavioral approaches to this that can work well. It's not always needing it -- Sometimes it is. And she was on the medication, and heard from a lot of parents who say it's -- Internalizing. Yep. Not one size -- Right, so important we hear from you and get this important information. Thank you, Dr. B.
