I'm in need of some help for my almost 9yr old son. He has been diagnosed with ADD and is currently taking Adderall XR 20mg. However, it doesn't seem to be helping with the behavioral issues we are having. We are currently trying to set up a nueropsych evaluation. but not sure what that exactly means, can anybody explain to me what the process may be like. He doesn't seem to listen to anything we say, he constantly has to get the last word in, he gets into everything (he's extremely sneaky), he lies, he has even stolen things from relatives and even us (his parents), he can be very aggresive with his sisters, and is extremely annoyed by others. We have tried just about everything with him. It has gotten to the piont that we have to lock most things up.
