High impact information on Dyslexia


Chemical compound and disease context of Dyslexia

  • Brains from male cases with dyslexia show symmetry of the planum temporale and predominantly left-sided cerebrocortical microdysgenesis [14].
  • The effects of piracetam in children with dyslexia [15].
  • These findings are discussed in light of Geschwind's hypothesis of a testosterone-mediated association within families between left-handedness, immune disorders, and dyslexia [16].
  • The choice of imaging planes (particularly coronal) and lack of bone artifact may, however, prove useful for studying macroscopic asymmetries in dyslexia [17].
  • Regional cerebral blood flow was measured under three task conditions in 14 men with severe developmental dyslexia and their control subjects using a xenon 133 inhalation technique [18].

Biological context of Dyslexia

  • These data suggest a direct link between a specific genetic background and a biological mechanism leading to the development of dyslexia: the risk haplotype on chromosome 6p22.2 down-regulates the KIAA0319 gene which is required for neuronal migration during the formation of the cerebral neocortex [19].
  • We conclude that the polymorphisms identified in the Finland sample are unlikely to be functional DNA changes contributing to dyslexia, and that if variation in EKN1 is causal such changes are more likely to be in regulatory regions that were not sequenced in this study [20].
  • We studied auditory event-related potentials (ERP) in newborns and 6-month-old infants, about half of whom had a familial risk for dyslexia [21].
  • Among five "backcross families" studied for chromosome 15 polymorphisms we found only negative lod scores, and at theta = 0.10 a negative score of -3.42; i.e., in our material we did not find any confirmation of the indication of linkage between dyslexia and a chromosome 15 polymorphism found in part of their material by Smith et al [22].
  • Early alexia and higher visual impairments characterize Posterior cortical atrophy (PCA), a progressive dementing syndrome most often caused by Alzheimer disease [23].

Anatomical context of Dyslexia

  • OBJECTIVE: To examine the size and asymmetry of the PT and its extension into the parietal lobe (planum parietale [PP]) in men with well-characterized, persistent dyslexia by using magnetic resonance imaging and 3-dimensional surface rendering techniques [24].

Gene context of Dyslexia

  • We conclude that DYX1C1 should be regarded as a candidate gene for developmental dyslexia [25].
  • Analyses of FOXP2 coding sequence in typical forms of specific language impairment (SLI), autism, and dyslexia have not uncovered any etiological variants [26].
  • Possible localisations of genes for dyslexia have been reported on chromosomes 15 (DYX1), 6p21.3-23 (DYX2), and 1p over the last 15 years [27].
  • 5. Using 100 families having at least two siblings affected with dyslexia, model-free linkage analysis revealed evidence for linkage to the DRD4-exon 3 repeat (two-point MFLOD = 2.27, P = 0.001) and to HRAS located just proximal to DRD4 (two-point MFLOD = 2.68, P = 0.0004) [28].
  • Supportive evidence for the DYX3 dyslexia susceptibility gene in Canadian families [29].
