Norman geschwind lecture: Geschwind’s lesson

Abstract

Norman Geschwind had a profound effect on behavioral neurology, not only on the basis of his research and theories expressed during his lifetime, but also through the impact that he had on colleagues privileged to train under him or have their work personally influenced by him. My work falls into the latter category. Novel associations between brain function~structure and behavior characterized his professional contributions, and offer a model for those who follow in his footsteps. He correctly predicted that like aphasic disorders, developmental dyslexia might be associated with deficits in color naming expressed currently as deficits in Rapid Automatized Naming. He stimulated anatomic research regarding patterns of asymmetry and microscopic architecture leading to the establishment of the Orton Dyslexia Neuropathology Laboratory at Beth Israel Hospital, Boston. He predicted an association between autoimmune disorders and reading disorders, an association that proved to be of genetic origin. He further predicted that reading disorders, like language disorders, would be cross-cultural and, similarly, their mechanism of production would be cross-cultural, although affected perhaps by the structure of the language to be learned. His suspicion that the clinical impression of male gender preponderance in dyslexia was accurate and carried biologic significance has recently been reconfirmed by colleagues at the Mayo Clinic in Rochester, Minnesota. Finally, with respect to dyslexia, one should not be surprised that since affect is influenced by brain architecture, developmental disorders characterized by altered brain

“…Μεταγενέστερες συνδυαστικές μελέτες εξέτασαν περιοχές του γονιδιώματος που είχαν προταθεί στη βάση της υπόθεσης μιας πιθανής σχέσης ανάμεσα στη δυσλεξία και τη λειτουργία του ανοσοποιητικού συστήματος (Duane, 2002). Αυτή η υπόθεση αρχικά προτάθηκε από τον Norman Geschwind σε μια σημαντική σειρά άρθρων στα μέσα του 1980 (Galaburda et al, 1985b).…”
