Dyslexia News and Research

RSS

Dyslexia is a learning disability that makes itself manifest primarily as a difficulty with the visual notation of speech or written language, particularly with reading the various man-made writing systems. It is separate and distinct from reading difficulties resulting from other causes, such as a non-neurological deficiency with vision or hearing, or from poor or inadequate reading instruction. This suggests that dyslexia results from differences in how the brain processes written and spoken language.

Map of the human brain sheds new light on dyslexia

Mapping the human brain at The University of Auckland has revealed that abnormal brain activity appears to be the reason why some dyslexia sufferers find it difficult to learn to read.

New research shows specific mechanisms may not exist for facial recognition

New research from Georgetown University Medical Center suggests that the brain may not have developed a specific ability for "understanding faces" but instead uses the same kind of pattern recognition techniques to distinguish between people as it uses to search for differences between other groups of objects, such as plants, animals and cars.

No brain no gain

How do we process numbers? A new project from the Austrian Science Fund FWF hopes to find the complex answer to this seemingly simple question by building on the recent findings of a team from Innsbruck.

Scientists find brain function most important to maths ability

Scientists at University College London (UCL) have discovered the area of the brain linked to dyscalculia, a maths learning disability. The finding shows that there is a separate part of the brain used for counting that is essential for diagnosis and an understanding of why many people struggle with maths.

Dyslexic children exhibit a different pattern of brain activity while reading

Brain images of children with dyslexia taken before they received spelling instruction show that they have different patterns of neural activity than do good spellers when doing language tasks related to spelling. But after specialized treatment emphasizing the letters in words, they showed similar patterns of brain activity.

Fish oil may improve behaviour of children with special educational needs

Students at a school for children with special educational needs in the UK are taking part in a study to see if taking fish oil supplements can improve their behaviour.

Changes in our early sensory experiences resulting from disease or environmental factors may shape our sensory perceptions

Our brain's ability to combine sensory information from a single event - such as seeing an ambulance and hearing its siren - has been shown to speed our reactions, help us identify objects and heighten our awareness.

Genetic link to dyslexia

About five million Germans have serious learning difficulties when it comes to reading and writing. It is frequently the case that several members of the same family are affected. So hereditary disposition seems to play an important role in the occurrence of dyslexia.

DCDC2 gene linked to dyslexia

Pediatric researchers at Yale School of Medicine have identified a gene on human chromosome 6 called DCDC2, which is linked to dyslexia, a reading disability affecting millions of children and adults.

Education research ignites Dyslexia debate

A Professor at Durham University's School of Education has sparked a major debate about the status of dyslexia and the value of labelling of some people with reading problems as "dyslexic".

Dyslexia overdiagnosed and a 'construct' says educationalist

According to a British professor dyslexia, an illness which afflicts millions of people is over diagnosed, and a "construct" with no scientific basis which had gained worldwide currency.

Researchers report the first objective measurement of the brain deficit in congenital amusia

While their friends enjoy the latest hit tunes, people who are tone deaf – in scientific terms, suffering from amusia – are excluded from the fun, unable to tell one note from another. The disorder can be congenital, present from birth, or acquired following injury to the brain.

Two regions of the human genome that appear to explain variation in IQ

It may be that IQ tests are not the only way to measure human intelligence. Scientists at The Queensland Institute of Medical Science (QIMR) have identified two regions of the human genome that appear to explain variation in IQ. Their work was published this week in the American Journal of Human Genetics and has drawn world-wide interest.

Neuroscientists redefine the dyslexic brain

The dyslexic brain may have a general problem forming perceptual categories, including the templates for printed letters and speech sounds, say University of Southern California (USC) neuroscientists.

New evidence for cause of dyslexia

Addressing a persistent debate in the field of dyslexia research, scientists at the University of Wisconsin-Madison and the University of Southern California (USC) have disproved the popular theory that deficits in certain visual processes cause the spelling and reading woes commonly suffered by dyslexics.

Research offers promise for people with learning disabilities

Learning disabilities such as dyslexia are believed to affect nearly one in 10 children. To better study them, a Northwestern University research team has developed a data-driven conceptual framework that links two well-established scientific concepts. In doing so, they also have developed a non-invasive diagnostic tool called BioMAP that can quickly identify children with learning disabilities.

Location on chromosome 2 that may contain one or more genes that contribute to dyslexia

Researchers trying to tease out the genetic basis of dyslexia have discovered a location on chromosome 2 that may contain one or more genes that contribute to the reading disorder and make it difficult for people to rapidly pronounce pseudowords.

New understanding to how cells in auditory system organize before hearing develops

Generations of neuroscientists have been indoctrinated into believing that our senses, thoughts, feelings and movements are orchestrated by a communication network of brain cells, or neurons, each responsible for relaying one specific chemical message called a neurotransmitter.

Genetic cause of dyslexia

A gene which is likely to be one of the causes of dyslexia in children has been discovered by researchers at Cardiff University.

Children suffering from ADHD may be ignoring visual information to their left

Children suffering from Attention Deficit Hyperactivity Disorder (ADHD) may be ignoring visual information to their left and being diagnosed mistakenly as having dyslexia, according to new research by Dr Tom Manly and colleagues at the Medical Research Council (MRC) Cognition and Brain Sciences Unit in Cambridge and published in Journal of Child Psychology and Psychiatry and Brain and Cognition.
