To diagnose and treat a brain disorder accurately, it would be necessary to look at the brain directly. Looking at behavior alone can miss a vital piece of the puzzle and provide an incomplete, or even a misleading, picture of the child's problems.

When looking at the brain, it is important to go beyond its structure to its function. This is because often in cognitive disorders, the structure of the brain is intact, but its function is compromised.
When I was 10 years old, a cousin of mine took me on a tour of his medical school. And as a special treat, he took me to the pathology lab and took a real human brain out of the jar and placed it in my hands. And there it was, the seat of human consciousness, the powerhouse of the human body, sitting in my hands.
Far too often, children with developmental disorders are diagnosed solely on the basis of their observable behavior, slotted into broad diagnostic pigeonholes and provided generalized treatments that may not always meet their specific needs.
Abnormalities in brain function have traditionally been detected using electroencephalography (EEG), which involves the measurement of the ongoing electrical activity generated by the brain.
