Attention-Deficit/Hyperactivity Disorder (ADHD) is a complex neurodevelopmental disorder affecting children and adults. This book, written by Odell Vining, Ph.D., licensed psychologist, provides glimpses into the ADHD world. Chapters are intentionally brief, and the entire document is consumable in one sitting. Upon completion, the reader should know more about ADHD, its history, causes, symptoms, and/or treatments. However, this document is not exhaustive nor replaces professional mental health or medical advice. Readers should independently review research and consult with qualified professionals before incorporating a new mental or physical health regimen.
