Dyslexia has been described as a difficulty in processing information which may be linked to deficiencies in short-term memory and visual coordination. It is an inherent weakness in short-term memory, that is either auditory or visual, which can make it extremely difficult for that person to learn and understand the relation between symbols and spoken sounds. This difficulty allows the person to be unable to correctly speak the correct flow of auditory sounds needed to make a word or sentence sound proper.
The range and severity of the problem of adult dyslexia varies widely between dyslexic people. The main areas of difficulty that occur most often are reading, writing, spelling, numeric, personal organization and time-keeping. However, the degree to which individuals may be affected ranges from mild spelling difficulties to severe organizational problems or complete illiteracy. In all reality there really is no such thing as a typical case of dyslexia.
In some cases people with dyslexia are unaware that they suffer from such a problem whereas others haven’t had a confirmed diagnosis until adulthood. Adult dyslexia is difficult to recognize and identify as it’s a problem that many people either don’t realize they have or they try to hide it. Simple tasks that a person with dyslexia may try to perform may become increasingly more difficult, such as taking down a message, which can lead to frustration and anxiety.
What Causes Adult Dyslexia?
Most research has concentrated on seeking to explain the cause of dyslexia, however this has proved to be somewhat unfruitful. Neurological research suggests that there may be some abnormality in the function of the left side of the brain which controls the speech system, whereas cognitive research in recent years has increasingly focused on problems of phonological awareness (the awareness of the speech sounds within words) and there has been speculation that these problems may be associated with a specific area of the brain.
One thing is conclusive however, it’s that the cause of dyslexia does center around an abnormality in the brain that prevents a person from correctly recognizing the right speech pattern. Many people that aren’t dyslexic can also have moments where they switch sounds out of their correct pattern which suggests to researches that perhaps it’s something that can be corrected in everyone.
Whatever the cause may be, there is absolutely no doubt that dyslexia leads to many literacy problems within individuals and an insensitivity to sounds within a word, which in time will lead to problems with reading and reading comprehension.
