Dyslexia-linked genetic variant decreases midline crossing of auditory pathways
(Aalto University) Finnish scientists have found that a rare dyslexia-linked genetic variant of the ROBO1 gene decreases normal crossing of auditory pathways in the human brain. The weaker the expression of the gene is, the more abnormal is the midline crossing. The results link, for the first time, a dyslexia-susceptibility gene to a specific sensory function of the human brain. (Source: EurekAlert! – Medicine and Health)

No commentsThe Joint Effects of Risk Status, Gender, Early Literacy and Cognitive Skills on the Presence of Dyslexia Among a Group of HighâRisk Chinese Children
This study sought to examine factors that are predictive of future developmental dyslexia among a group of 5âyearâold Chinese children at risk for dyslexia, including 62 children with a sibling who had been previously diagnosed with dyslexia and 52 children who manifested clinical atârisk factors in aspects of language according to testing by paediatricians. The ageâ5 performances on various literacy and cognitive tasks, gender and group status (familial risk or language delayed) were used to predict developmental dyslexia 2âyears later using logistic regression analysis. Results showed that greater risk of dyslexia was related to slower rapid automatized naming, lower scores on morphological awareness, Chinese character recognition and English letter naming, and gender (boys had…

No commentsValidity of a Protocol for Adult SelfâReport of Dyslexia and Related Difficulties
ConclusionsSelfâreport scales of reading and of attention difficulties are useful for identifying adults with reading and attention difficulties which may confer risks on their children of related problems. It is important for research following children at family risk of dyslexia to be aware of these effects. Copyright © 2012 John Wiley & Sons, Ltd. (Source: Dyslexia)

No commentsWorking memory function in Chinese dyslexic children: A near-infrared spectroscopy study
This study used Near-Infrared
Spectroscopy (NIRS) imaging to measure the regional cerebral blood volume (BV) and the changes of cerebral activation in the
left prefrontal cortex of 12 Chinese dyslexic children and their 12 age-matched normal controls during the Paced Visual Serial
Addition Test (PVSAT). Results showed that the scores of PVSAT of dyslexic children were significantly lower than those of
the normal children (t=3.33, P<0.01). The activations of the left prefrontal cortex in the normal group were significantly greater than those of dyslexic
children (all P<0.01). Our results indicated that Chinese dyslexia had a general deficiency in working memory and this may be caused by the
abnormal metabolic activity of brain blood volume in the left prefrontal cortex and the d…

No commentsBrain scans could diagnose dyslexia in children before they even learn to read and head off difficulties at school
A team from Children’s Hospital Boston said they could see signs of dyslexia on brain scans in children as young as four years old – and younger children are most responsive to intervention. (Source: the Mail online | Health)

No commentsBrain MRIs May Provide An Early Diagnostic Marker For Dyslexia
Children at risk for dyslexia show differences in brain activity on MRI scans even before they begin learning to read, finds a study at Children’s Hospital Boston. Since developmental dyslexia responds to early intervention, diagnosing children at risk before or during kindergarten could head off difficulties and frustration in school, the researchers say. Findings appear this week in the online Early Edition of the Proceedings of the National Academy of Sciences… (Source: Health News from Medical News Today)

CHICAGO (Reuters) – Instead of waiting for a child to experience reading delays, scientists now say they can identify the reading problem even before children start school, long before they become labeled as poor students and begin to lose confidence in themselves. (Source: Reuters: Health)
