Anyone read it? It is from 1995 so might be outdated - but there is a part in the book that says: "There are also psychological tests that can provide additional evidence in making a diagnosis. Certain subtests of the WISC (Wechsler Intelligence Scale for Children)- a standard test for children-may suggest ADD. Typically, the subscores for digit span, arithmetic, and coding are low in ADD. Additionally, there is often a wide split between what is called the verbal subscore and what is called the performance subscore." Do you think this is still true? Do you think this is most often the case? I don't recall ever reading this before. Do you think you could look at any intelligence test and expect to see a wide split between the verbal and performance subscores in people with ADHD?
