Unfortunately, may people don't have a very good understanding of the neurobiology behind ADHD, Anxiety and Depression. It's hard for a layperson to get a good idea of the "whole picture," --anatomy, genetics, and neurochemistry--and how that fits in with a clinical diagnosis. This talk is aimed at educating people about a complex topic--but in a simple, easy to understand way, and focusing on the interesting parts! How ADHD, Anxiety, and Depression influence each other are important clinically and have an understandable biological connection as well. The difference in the brain between acute and chronic anxiety and depression will be discussed. After delving into the biology of each disorder and how they interact, you learn how environmental factors influence the biology and how medications for ADHD work. Knowing the biology of this will be an invaluable tool--for the ADHDer, for the ADHD's family and loved ones, for teachers, and for coaches as well as for doctors. By being able to picture the biology, they'll more easily be able to manage it. By the end of the talk, each attendee should have an idea about the important aspects of the biology of ADHD, Anxiety and Depression. and how to influence it.
