Although specific learning disability (SLD), including dyslexia, is defined in terms of academic failure, SLD children differ from normal children on a variety of dimensions. In addition to academic difficulties, they may have problems with motor coordination, attentional deficits, and behavioral difficulties. These additional abnormalities are not the reason for the learning difficulties (e.g., dyslexia), but may be related to the underlying brain problems. Many questions related to these neurobehavioral disorders still have not received complete answers, including: What are the causes of SLD—genetic, neurological, social, educational—or a combination of these? Can we identify, using various methodologies, brain abnormalities that will explain the nature of SLD and also allow us to arrive at more specific diagnoses? What is the pathophysiology by which certain etiologies cause SLD? If the etiology is genetic, what is the pathophysiology by which genetic abnormality brings about a specific learning disability?
