Research into potential genetic causes of dyslexia has its roots in post-autopsy examination of the brains of people with dyslexia. [37] Observed anatomical differences in the language centers of such brains include microscopic cortical malformations known as ectopias , and more rarely, vascular micro-malformations, and microgyrus —a smaller ...
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 ...
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.
Dyslexia is a brain-based learning disorder "that affects how people process written language, especially when it comes to reading, ... While exact causes are not thoroughly defined, we do know ...
The phonological deficit hypothesis is a prevalent cognitive-level explanation for the cause of reading difficulties and dyslexia. [1] It stems from evidence that individuals with dyslexia tend to do poorly on tests which measure their ability to decode nonsense words using conventional phonetic rules, and that there is a high correlation between difficulties in connecting the sounds of ...
Whether you're a parent, grandparent or educator, here's what to know.
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.
When dyslexia was studied within children, it was found that dyslexic children were often stressed as well as mentally exhausted. These children would place little to no importance on their present state, a behavior that would continue into adulthood. [11] It remains unclear as to whether dyslexia is a symptom of dyschronometria, a cause, or ...
