It was concluded that computed axial tomography of the brain is not a necessary screening procedure in the evaluation of the child with minimal brain dysfunction or learning disabilities unless there is evidence of a focal neurologic deficit. (Author)

This article reviews various models in the neurological conceptualization of attention deficit disorder (ADD), with and without hyperactivity. It discusses neuroanatomical, neurochemical, and neurophysiological perspectives on ADD. (Author/DB)

The article discusses neuropsychological and treatment aspects of brain behavior disorders in children from the standpoint of terms such as minimal brain dysfunction, learning disabilities, hyperactivity, and hyperkinetic syndrome. (Author/DLS)

We report the first major genetic study of mild mental impairment. From a representative sample of 3,886 twins (1,314 monozygotic, 1,296 dizygotic same-sex, and 1,276 dizygotic opposite-sex), the lowest 5% were selected on a composite measure of verbal and nonverbal abilities assessed by parents when the twins were 2, 3, and 4 years of age. Twin…

Used several different measures on 45 patients (32 boys, 13 girls). The limited amount of covariation found suggests that neuropsychological deficits may be a diffuse problem that…

This article uses a self-organizing systems (SOS) framework to explain the complexity of learning disabilities (LD) and suggest that traditional classification schema may be inadequate. It explains principles of self-organizing systems and reviews research concerning reading and math disabilities and the roles of language, attention, working…
