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.
