Just the Facts: Dyslexia BasicsInformation provided by the International Dyslexia Association What is dyslexia? Dyslexia is a language based learning disability. It accounts for approximately 85% of all people with a learning disability. Dyslexia refers to a cluster of symptoms which result in people having difficulties with specific language skills, particularly reading. Students with dyslexia may experience difficulties in other language skills such as spelling, writing, and speaking. Dyslexia is a life-long status, however, its impact can change at different stages in a persons life. It is referred to as a learning disability because dyslexia can make it very difficult for a student to succeed academically in the typical instructional environment. What causes dyslexia? The exact causes of dyslexia are still not completely clear, but anatomical and brain imagery studies show differences in the way the brain of a dyslexic person develops and functions. Moreover, people with dyslexia have been found to have problems with discriminating sounds within a word, a key factor in their reading difficulties. Dyslexia is not due to either lack of intelligence or a desire to learn; with appropriate teaching methods dyslexics can learn successfully. How widespread is dyslexia? Current studies suggest that at least 15-17% of the population is dyslexic. Dyslexia occurs in people of all backgrounds and intellectual levels. There is strong evidence that dyslexia runs in families; dyslexic parents are far more likely to have children who have dyslexia. Some people are identified as dyslexic early in their lives, but for others their dyslexia goes unidentified until they get older. People who are very bright can be dyslexic. They are often gifted in areas that do not require strong language skills, such as art, computer science, design, drama, electronics, math, mechanics, music, physics, sales,and sports. What are the effects of dyslexia? The impact that dyslexia has is different for each person and depends on the severity of the condition and the ap-proaches of the remediation. The most common effects are problems with reading, spelling, and writing. Some dyslexics do not have much difficulty with early reading and spelling tasks but do experience great problems when more complex language skills are required, such as grammar, understanding textbook material, and writing essays. People with dyslexia can also have problems with spoken language. They
may find it difficult to express themselves clearly, or to fully comprehend
what others mean when they speak. Such language problems are often difficult
to recognize, but they can lead to major problems in school, in the workplace,
and in relating to other people. The effects of dyslexia reach well beyond
the classroom. How is dyslexia diagnosed? A formal evaluation is needed to discover if a person is dyslexic. The evaluation assesses intellectual ability, information processing, psycho-linguistic processing, and academic skills. It is used to determine whether or not a student is reading at the expected level, and takes into account the individuals family background and overall school performance. The testing can be conducted by trained school or outside specialists. What are the signs of dyslexia? The problems displayed by individuals with dyslexia involve difficulties in acquiring and using languagereading and writing letters in the wrong order is just one manifestation of dyslexia and does not occur in all cases. Other problems experienced by dyslexics include:
Not all students who have difficulties with these skills are dyslexic. Formal testing is the only way to confirm a diagnosis of suspected dyslexia. How is dyslexia treated? Dyslexia is a lifelong condition. With proper help people with dyslexia
can learn to read and/or write well. Early identification and treatment
is the key to helping dyslexics achieve in school and in life. Most people
with dyslexia need help from a teacher, tutor, or therapist specially
trained in using a multisensory, structured language approach. It is important
for these individuals to be taught by a method that involves several senses
(hearing, seeing, touching) at the same time. Many individuals with dyslexia
need one-on-one help so that they can move forward at their own pace.
For students with dyslexia, it is helpful if their outside academic therapists
work closely with classroom teachers. Schools can implement academic modifications to help dyslexic students
succeed. For example, a student with dyslexia can be given extra time
to complete tasks, or help with taking notes, and/or appropriate work
assignments. Teachers can give taped tests or allow dyslexic students
to use alternative means of assessment. Students can benefit from listening
to books-on-tape and from writing on computers. What are the rights of a dyslexic person? For more information: IDA encourages the reproduction and distribution of this fact sheet. If portions of the text are cited, appropriate reference must be made.
