The paper presents a discussion of human mental processes as they relate to learning disabilities. Pathognomonic symptoms associated with disturbances to brain areas or functional systems are discussed, as well as treatment procedures. This brain behavior relationship is offered as a basis for a classification system that is seen to more clearly define attention and learning disabilities and to afford more precise and reliable strategies for diagnosis and treatment. Ninety-two symptoms are grouped in a screening checklist format for the areas of attention, perception, mood, memory, and movement. A multidisciplinary treatment approach involving medicine, neuropsychology, and education is recommended. (Author/DB)
