DYSLEXIA

What is dyslexia??

Developmental reading disorder, also called dyslexia, is a reading disability that occurs when the brain does not properly recognize and process certain symbols.

Causes, incidence, and risk factors

Developmental reading disorder (DRD), or dyslexia, occurs when there is a problem in areas of the brain that help interpret language. It is not caused by vision problems. The disorder is a specific information processing problem that does not interfere with one's ability to think or to understand complex ideas. Most people with DRD have normal intelligence, and many have above-average intelligence.

DRD may appear in combination with developmental writing disorder and developmental arithmetic disorder. All of these involve using symbols to convey information. These conditions may appear alone or in any combination.

DRD often runs in families.

Symptoms

A person with DRD may have trouble rhyming and separating sounds that make up spoken words. These abilities appear to be critical in the process of learning to read. A child's initial reading skills are based on word recognition, which involves being able to separate out the sounds in words and match them with letters and groups of letters.

Because people with DRD have difficulty connecting the sounds of language to the letters of words, they may have difficulty understanding sentences.

True dyslexia is much broader than simply confusing or transposing letters, for example mistaking ”b” and “d.".

In general, symptoms of DRD may include:

• Difficulty determining the meaning (idea content) of a simple sentence

• Difficulty learning to recognize written words

• Difficulty rhyming

DRD may occur in combination with writing or math learning problems.
