Why Alphabet Soup?

Consider this: *ASD, ADHD, LD, SPD, ODD and so on. Looks like Alphabet Soup to me! These are just a few of the acronyms or labels floating around that all have their roots in how our basic operating system, the central nervous system (CNS), operates. People have referred to this using the technology metaphor of having either a PC or a MAC operating system. Nothing wrong or better with either system and they both produce the same results, they just operate differently. There are lots of variations in our human nervous systems. Some have profound effects in how we function in the world and others are so minor that we barely notice them. So what makes us tick?
