Four physiological conditions associated with later learning disabilities are noted: Turner Syndrome (a chromosomal abnormality), preterm children with intracranial hemorrhage, children with incompletely developed connecting fibers between the cerebral hemispheres, and children with acquired brain injury.

This article highlights the scientific contributions of nineteenth-century German researchers in describing neuropsychologic dysfunction and in conceptualizing and cerebrally localizing clinical syndromes associated with learning disabilities. Noted are contributions of Pierre Paul Broca, Carl Wernicke, Ludwig Lichtheim, Hugo Karl Liepmann, B.…

The possibility that four famous men--Thomas Alva Edison, Woodrow Wilson, Hans Christian Andersen, and Leonardo da Vinci--might have been reading disabled is considered by examining information concerning: (1) biographical records, (2) cognitive characteristics, (3) neuropsychological characteristics, and (4) biological characteristics.

This article summarizes work in progress at the Bowman Gray School of Medicine (North Carolina) on the structure and physiological profiles of reading disability and relates the findings to core left-hemisphere language functions. Data add evidence of the structural anomalies associated with dyslexia and evidence of its heritability, especially of…
