Thomas E. Brown, Ph.D., author of Attention Deficit Disorder – The Unfocused Mind in Children and Adults, has aptly illustrated the problem of ADD. This is the first paragraph of the introduction of his book.
“Often people think of “focus” as holding a camera still and adjusting the lens for a clear picture of an unmoving object. That is not the meaning of focus in the title of this book. Rather, focus refers here to a complex, dynamic process of selecting and engaging what is important to notice, to do, to remember, moment to moment. Much as a careful driver focuses on the task of driving a car in heavy traffic by actively looking ahead while also checking mirrors, observing road signs, braking, and so on (all while monitoring dashboard gauges, keeping in mind the speed limit and destination, and ignoring the temptation to look too long at interesting sights), a person employs this very active, rapidly shifting, repeatedly readjusted deployment of attention and memory as the “focus” needed to plan and control ongoing activity. Such focus is extremely difficult for the 7 to 10 percent of the world’s population who suffer from a syndrome of cognitive impairments currently known as attention deficit disorder (ADD) or attention-deficit hyperactivbity disorder (ADHD)”
