NEUROLOGICAL FACTORS IN READING DISABILITY.

An overview is presented of that portion of the literature on reading disability wherein neurological defect is seen as causal or correlative. From the publication of Hinshelwood's "Congenital Word Blindness" (1917) to the present, investigators have considered the possible association of reading difficulty with genetically determined neurological defect, with cerebral damage, with biochemical imbalance inhibiting synaptic transmission, and with some form of maturational lag.
