This article published from Yale briefly informs the reader about what dyslexia is, and how it can impact a person's everyday life. Something that is very interesting is even though dyslexia can create a setback when interpreting literature, many people who have dyslexia are some of the most creative thinkers. This just proves that the condition cannot define the intelligence of an individual. Even though it cannot be cured, it is very possible to have success and "overcome" this obstacle.

"But a series of ingenious experiments have shown that many people with dyslexia possess distinctive perceptual abilities. For example, scientists have produced a growing body of evidence that people with the condition have sharper peripheral vision than others. ... Moreover, these capacities appear to trade off: if you're adept at focusing on details located in the center of the visual field, which is key to reading, you're likely to be less proficient at recognizing features and patterns in the broad regions of the periphery. ... Although people with dyslexia are found in every profession, including law, medicine and science, observers have long noted that they populate fields like art and design in unusually high numbers. ... in some situations, it turns out, those with dyslexia are actually the superior learners."

Apparently people who have dyslexia possess skills that are superior to normal readers. People with dyslexia have increased perception. An example would be sharper peripheral vision.

Parents and teachers across the country have raised concerns about some schools hesitating, or completely refusing, to say the word. As the most common learning disability in the U.S., dyslexia affects somewhere between 5 and 17 percent of the population. Under the Individuals with Disabilities Education Act (IDEA), schools are required to provide special services to help these students - things like reading tutors and books on tape. But those special services can be expensive, and many schools don't have the resources to provide these accommodations. That has led some parents and advocates to worry that some schools are making a careful calculation: If they don't acknowledge the issue - or don't use the word "dyslexia" - then they are not obligated to provide services.

Dyslexia is the most common learning disability in the United States. It touches the lives of millions of people. People with dyslexia don't naturally process the written word. They don't easily break it into smaller units that can be turned into sounds and stitched together. This makes reading a laborious - even exhausting - process. Writing, too.

"So this summer's news that research is increasingly tying dyslexia not just to reading, but also to the way the brain processes spoken language, was no surprise to me. I found many ways around my dyslexia, but I still have trouble transforming words into sounds. I have to memorize and rehearse before reading anything aloud, to avoid embarrassing myself by mispronouncing words."

There are many different types of dyslexia that people can have either it is from reading, speaking, spelling or comprehending. This article talks about how certain types of dyslexia is shown and how people get it in the first place.

Brain-imaging studies have shown that music activates many diverse parts of the brain, including an overlap in where the brain processes music and language. Brains of people exposed to even casual musical training have an enhanced ability to generate the brain wave patterns associated with specific sounds, be they musical or spoken, said study leader Nina Kraus, director of the Auditory Neuroscience Laboratory at Northwestern University in Illinois. Musicians have subconsciously trained their brains to better recognize selective sound patterns, even as background noise goes up. In contrast, people with certain developmental disorders, such as dyslexia, have a harder time hearing sounds amid the din. Musical experience could therefore be a key therapy for children with dyslexia and similar language-related disorders. Harvard Medical School neuroscientist Gottfried Schlaug has found that stroke patients who have lost the ability to speak can be trained to say hundreds of phrases by singing them first. Schlaug demonstrated the results of intensive musical therapy on patients with lesions on the left sides of their brains, those areas most associated with language. Before the therapy, these stroke patients responded to questions with largely incoherent sounds and phrases. But after just a few minutes with therapists, who asked them to sing phrases and tap their hands to the rhythm, the patients could sing "Happy Birthday," recite their addresses, and communicate if they were thirsty. "The underdeveloped systems on the right side of the brain that respond to music became enhanced and changed structures," Schlaug said at the press briefing.

Dyslexia is the most common learning disability in the U.S. Scientists are exploring how human brains learn to read, and are discovering new ways that brains with dyslexia can learn to cope. 2 areas on the left side of the brain are key for reading: 1. the left temporoparietal cortex: traditionally used to process spoken language. When learning to read, we start using it to sound out words. 2. the occipitotemporal cortex: part of the visual processing center, located at the base of our brain, behind our ears. A person who never learned to read uses this part of the brain to recognize objects - like a toaster or a chair. But, as we become fluent readers, we train this brain area to recognize letters and words visually. These words are called sight words: any word that you can see and instantly know without thinking about the letters and sounds. This requires retraining the brain. When recognizing a chair, the brain naturally sees it from many different angles - left, right, up, down - and, regardless of the perspective, the brain knows it is a chair. But that doesn't work for letters. Look at a lowercase 'b' from the backside of the page, and it looks like a lowercase 'd.' They are the same basic shape and, yet, two totally different letters. But, as it does with a chair, the brain wants to recognize them as the same object. Everyone - not just people with dyslexia - has to teach the brain not to conflate 'b' and 'd'. The good news: intervention and training can help. At the end of the six week training sessions with dyslexics, the brain areas typically associated with reading, in the left hemisphere, became more active. Additionally, right hemisphere areas started lighting up and helping out with the reading process. The lead scientist, Dr. Eden, says this is similar to what scientists see in stroke victims, where other parts of the brain start compensating.

Brain imaging studies have explored the neural mechanisms of recovery in adults following acquired disorders and, more recently, childhood developmental disorders. However, the neural systems underlying adult rehabilitation of neurobiologically based learning disabilities remain unexplored, despite their high incidence. Here we characterize the differences in brain activity during a phonological manipulation task before and after a behavioral intervention in adults with developmental dyslexia. Phonologically targeted training resulted in performance improvements in tutored compared to nontutored dyslexics, and these gains were associated with signal increases in bilateral parietal and right perisylvian cortices. Our findings demonstrate that behavioral changes in tutored dyslexic adults are associated with (1) increased activity in those left-hemisphere regions engaged by normal readers and (2) compensatory activity in the right perisylvian cortex. Hence, behavioral plasticity in adult developmental dyslexia involves two distinct neural mechanisms, each of which has previously been observed either for remediation of developmental or acquired reading disorders.

Dyslexia stems from physiological differences in the brain circuitry. Those differences can make it harder, and less efficient, for children to process the tiny components of language, called phonemes. Using cutting-edge MRI technology, the researchers are able to pinpoint a specific neural pathway, a white matter tract in the brain's left hemisphere that appears to be related to dyslexia: It's called the arcuate fasciculus. "It's an arch-shaped bundle of fibers that connects the frontal language areas of the brain to the areas in the temporal lobe that are important for language," Elizabeth Norton, a neuroscientist at MIT's McGovern Institute of Brain Research, explains.

As e-readers grow in popularity as convenient alternatives to traditional books, researchers have found that convenience may not be their only benefit. The team discovered that when e-readers are set up to display only a few words per line, some people with dyslexia can read more easily, quickly and with greater comprehension.

Thanks, Mark--I'd forgotten that this is one of the sample questions asked in the course description: "Is dyslexia in Chinese the same as in English?"

This is a simulation of reading text online if you are dyslexic.

While this article primarily addresses the phenomenon of dysmusia, difficulty in reading music, it also talks about the cognitive underpinnings of music reading. In the brain, reading music is a widespread, multi-modal activity, meaning that many different areas of the brain are involved at the same time. It includes motor, visual, auditory, audiovisual, somatosensory, parietal and frontal areas in both hemispheres and the cerebellum - making music reading truly a whole brain activity. With training, the neural network strengthens. Even reading a single pitch activates this widespread network in musicians. The article also reiterates a pattern that researchers are finding: while text and music reading share some networks, they are largely independent. The pattern of activation for reading musical symbols and letters is different across the brain. Scientists have determined this via studies of patients with limited brain damage, as brain injury impaired reading of one coding system but spared the other.
