Management of dyslexia depends on a multitude of variables; there is no one specific strategy or set of strategies that will work for all who have dyslexia.. Some teaching is geared to specific reading skill areas, such as phonetic decoding; whereas other approaches are more comprehensive in scope, combining techniques to address basic skills along with strategies to improve comprehension and ...
Dyslexia is believed to be caused by the interaction of genetic and environmental factors. Some cases run in families. Dyslexia that develops due to a traumatic brain injury, stroke, or dementia is sometimes called "acquired dyslexia" or alexia. The underlying mechanisms of dyslexia result from differences within the brain's language processing ...
Dyslexia is a learning difficulty that primarily affects the skills involved in accurate and fluent word reading and spelling. Characteristic features of dyslexia are difficulties in phonological awareness, verbal memory and verbal processing speed. Dyslexia occurs across the range of intellectual abilities.
In the United States, researchers estimate the prevalence of dyslexia to range from three to ten percent of school-aged children, though some have put the figure as high as 17 percent. [ 9 ] [ 10 ] Recent studies indicate that dyslexia is particularly prevalent among small business owners, with roughly 20 to 35 percent of US and British ...
These behaviors are seen in many children as they learn to read and write, and are not considered to be defining characteristics of dyslexia. [10] School-age children with dyslexia may exhibit signs of difficulty in identifying or generating rhyming words, or counting the number of syllables in words—both of which depend on phonological ...
The cerebellar theory of dyslexia asserts that the cause of dyslexia is an abnormality in the cerebellum (a region in the back of the brain), which in turn cause disruption in normal development, which causes issues with motor control, balance, working memory, attention, automatization, and ultimately, reading.
The problems underlying this type of dyslexia are related directly to memory and coding skills that allow representation of printed letters and words, not to poor phonological processing. [11] This type of dyslexia is also termed surface dyslexia because people with this type have the inability to recognize words simply on a visual basis.
In 1964, the Associated for Children with Learning Disabilities (now known as Learning Disability Association of America) was formed. [2] In 1968, Makita suggested that dyslexia was mostly absent among Japanese children. [15] A 2005 study shows that Makita's claim of rarity of incidence of reading disabilities in Japan to be incorrect. [16]
