Scientists have found a distinctive neural signature that explains why people with the condition find it hard to read. The researchers took MRI scans of individuals with and without reading difficulties. The participants performed a variety of tasks while getting their brains scanned.

They discovered that those diagnosed with the condition has reduced the ability to acclimate to repeated input. Moreover, they also found out that the brain’s plasticity is reduced as well. Plasticity supports the ability to learn new things.

Dyslexia breakthrough as doctors discover differences in sufferers’ brains which could explain why they struggle to read

MIT neuroscientists found that the brains of people with dyslexia have a diminished ability to acclimate to a repeated input, like seeing the same word a number of times. The findings suggest the brain’s plasticity, which supports the ability to learn new things, is reduced in these cases. Read more…

Boston Globe says that the brain abnormalities that cause the condition might be deeper that what we thought. A study was published last Wednesday in the journal Neuron. It discussed that the brains of people with the reading disorder might react differently to words, objects, and faces.

Dyslexia is a neurological disorder that might prove to be challenging even in highly intelligent people. It’s hard to learn how to read especially because of problems relating speech sounds with letters and words.

Study Suggests Dyslexics Suffer From Less Brain Plasticity

The brain abnormalities that cause dyslexia may be deeper and more pervasive than previously thought, according to research from the Massachusetts Institute of Technology. Read more…

Time.com says this is more than just a reading disorder. People with dyslexia have a hard time with adaptability. When the brain experiences something new, may it be a word or a voice it uses neural energy to collect as much information about the stimulus as possible.

If it does this every time it hears the same voice, it would be deemed as inefficient. What it does is that it adapts and quickly triage new encounters from familiar ones.

Why Dyslexia Is More Than a Reading Disorder

But in the latest research published in the journal Neuron, scientists led by John Gabrieli, a professor of brain and cognitive sciences at Massachusetts Institute of Technology, found that dyslexia may be due to a much broader difference in brain function. Read more…

The researchers believe that this might be the first ever study to take a look at evidence related to reduced plasticity in the brain of dyslexics. The findings help educators understand what the condition is really about so they can improve their teaching strategies and help students better.
