I've noticed this popping up in a few threads lately. How does one tell the diff between ADHD and anxiety? I know it's not cut and dried, and it's easier to tell as they get older, but are there any real hallmarks? When my son has wheat, or when the Adderal wears off, the first thing he does is pace sideways back and forth, like he's got a soccer ball between his ankles. Then he starts hopping like he's got ants in his pants. I often ask him if he's got to use the restroom. Then he starts to talk a lot, and his voice gets louder. And then he gets in your face and gets demanding. Whatever it is, he wants it NOW. He needs to know WHEN we're going, (where ever), why we can't leave now, and he interrupts phone conversations and hangs all over you. He always thinks that if he doesn't return his friends' phonecalls immediately, they will up and disappear off the face of the earth. He just doesn't "get" planning ahead. I'm thinking my son has both.
