Dyslexia — also called specific reading disability — is a long-lasting language problem that affects many people. It is one of a group of conditions known as learning disabilities.
Dyslexia stems from not being able to recognise and learn the connection between the spoken and written forms of a language, or a failure to recognise the sound associated with a written symbol or word. This is important because to learn to read a word a child must first split that word into its sequence of component sounds (called phonemes), e.g. the word ‘peg’ has p-e-g. Difficulty in ‘sounding out’ words like this means that a child can’t achieve the successful repetition of a word necessary to acquire words as part of their ‘sight vocabulary’. Having a word as part of the sight vocabulary means that a person can instantly recognise it without having to decipher it every time by ‘sounding it out’.
Among other symptoms, dyslexia may be characterised by the following.
The exact cause of dyslexia has not yet been identified, but recent evidence points to abnormalities in the brain. Scientists have found that specific areas of the brain are involved; these areas:
Some researchers believe that the brain abnormalities associated with dyslexia start when the fetus is developing in the womb. Premature birth and low birth weight are risk factors for dyslexia. Other findings suggest that genetic (inherited) factors also play an important part in dyslexia.
Dyslexia can occur in children with normal, or superior, intelligence and abilities, who are sometimes mistakenly thought to have an intellectual disability. A child with dyslexia who has not been properly diagnosed may suffer from low self-esteem because of the tough time they have keeping up with the learning pace of their classmates. Although dyslexia can occur in people of any intellectual ability, children with the condition often appear to be not trying hard enough at school. Problems with school can lead to a student feeling stressed and discouraged about continuing, which can have major consequences for his or her future working life.
Many people with dyslexia have problems reading from left to right and reversing words and letters, but others with the condition may have other problems in actually recognising the visual form of words. Dyslexia may be accompanied by, or cause other problems such as:
Many people with dyslexia are gifted in areas that don’t need strong language skills, such as art, design, computing and sports. Some are highly intuitive and extremely creative. They should never be considered to have an intellectual disability without further evaluation. One of the most famous thinkers of our time, Albert Einstein, had dyslexia.
To diagnose dyslexia, a series of standardised questionnaire-type tests are usually given. The tests evaluate a child’s intellectual ability, their academic skills, and their information and language processing skills. Your child’s hearing and vision may also be tested. Your doctor will be able to give you more information about the whole process and/or refer you to a specialist in the field.
Children with dyslexia may have trouble keeping up at school because reading is the basis for many school subjects. However, many schools offer support for children with learning difficulties such as dyslexia.
A team approach is often used to support children with learning difficulties — the team may consist of just you and your child’s teacher, or it may include the principal, school counsellor, support teachers and health professionals such as speech pathologists and educational psychologists. The team will assess your child’s needs and see whether your child would benefit from an individualised learning program. This type of program can identify the learning needs of your child and outline specific teaching methods to meet these learning needs.
You are an important part of the team because you know your child better than anyone and you will be your child’s most consistent teacher. So it’s a good idea to talk to your child’s teacher about how things are done in the classroom and what’s expected of your child, so that you can help as much as possible. You should also tell your child’s teacher if your child is finding the work too much.
With this type of approach, your child can be supported; particularly during potentially difficult periods such as starting school and moving from primary to secondary school.
