Gilger, Jeffrey W. – Journal of Learning Disabilities, 2001
This introductory article briefly describes each of the following eight articles in this special issue on the neurology and genetics of learning related disorders. It notes the greater appreciation of learning disability as a set of complex disorders with broad and intricate neurological bases and of the large individual differences in how these…

Joseph, Jane; Noble, Kimberly; Eden, Guinevere – Journal of Learning Disabilities, 2001
This paper reviews studies using positron emission tomography and functional magnetic resonance imaging in adults to study the reading process and notes that general networks of regions seem to be uniquely associated with different components of the reading process. Findings are evaluated in light of technical and experimental limitations and…

Hynd, George W.; And Others – Journal of Learning Disabilities, 1991
Morphometric analysis of magnetic resonance imaging scans revealed that, compared to nondisabled controls, the seven children with attention deficit hyperactivity disorder had a smaller corpus callosum. Results suggest that subtle differences may exist in the brains of these children and that deviations in normal corticogenesis may underlie the…

Flynn, Jane M.; And Others – Journal of Learning Disabilities, 1992
The construct validity of Boder's typology of dyslexia was investigated using quantified electroencephalography with 39 children (ages 7-11) during a reading task and at rest. Results supported beta frequency differences in anticipated regions by dyslexia subtype during the reading task. However, the direction of difference hypothesis was not…

Gross-Tsur, Varda; And Others – Journal of Learning Disabilities, 1995
This study reports clinical characteristics of developmental right-hemisphere syndrome, a nonverbal learning disability, in 20 children (mean age 9.5 years) who also manifested attention-deficit/hyperactivity disorder, graphomotor problems, and slow performance. Diagnostic criteria included emotional and interpersonal difficulties, paralinguistic…

Clarke, Adam R.; Barry, Robert J.; McCarthy, Rory; Selikowitz, Mark – Journal of Learning Disabilities, 2002
A study investigated electroencephalographic (EEG) differences between children with attention-deficit/hyperactivity disorder with reading disabilities (ADHD + RD) (n=20) or without (n=20), and 20 controls. Results indicate differences found in the ADHD + RD group represent an electrophysiological component associated with the reading disability…

Lord-Maes, Janiece; Obrzut, John E. – Journal of Learning Disabilities, 1996
This article discusses recent findings concerning cognitive outcomes in traumatic brain injury (TBI) in children and adolescents, with a particular focus on age differences with TBI. It suggests a relationship between specific learning disorders and brain dysfunction, addresses differential hemispheric functioning with TBI, and outlines recent…
