Neurocognitive risk factors for developmental dyslexia

Different underlying neurocognitive deficits in developmental dyslexia: a comparative study.

The aim of this study was to investigate the role of several specific neurocognitive functions in developmental dyslexia (DD). The performances of 60 dyslexic children and 65 age-matched normally reading children were compared on tests of phonological abilities, visual processing, selective and sustained attention, implicit learning, and executive functions. Results documented deficits in dysle...

Developmental dyslexia: predicting individual risk

BACKGROUND Causal theories of dyslexia suggest that it is a heritable disorder, which is the outcome of multiple risk factors. However, whether early screening for dyslexia is viable is not yet known. METHODS The study followed children at high risk of dyslexia from preschool through the early primary years assessing them from age 3 years and 6 months (T1) at approximately annual intervals on...

Developmental dyslexia.

T he term developmental dyslexia ("specific reading retardation") refers to an unexpected difficulty in reading in children and adults who otherwise possess the intelligence, motivation, and schooling considered necessary for accurate and fluent reading. The concept has had a chequered career, with debates about its definition, origin, and causes, and indeed about its validity as a distinct ent...

Developmental Dyslexia

The possible causes and correlates of such difficulty have been the focus of a great deal of theorizing since before the turn of the twentieth century, when W. Pringle Morgan (1896) described a 14-year-old boy named Percy who suffered from pronounced difficulty learning to read and spell, despite normal achievement in other academic areas. Because he could find no evidence of definitive brain i...
