A problem that effects four to five percent of the world population, or some 20 million people, is dyslexia. Dyslexia is a general term that refers to a variety of oral and written language input or output problems. Dyslexia affects people of any intellectual ability, socioeconomic group, and both males and females; even though three times as many males are diagnosed and receive specialized training for their disabilities.
Although to some people this disorder may be very noticeable, it can really sneak up on you. About 60% of individuals with dyslexia have difficulties with phonological awareness, which is evident in reading, writing and spelling. Most also have difficulties with language, memory, and sequence processing in Mathematics, too. Some warning signs to look for in students ages six through eleven include spelling the same word several different ways, confused or reversed word order when reading aloud, and poor reading comprehension. With older students and adults, dyslexia is often suspected with students that have difficulty remembering what is read aloud, has difficulty taking notes from a presentation, or is a very poor speller. Most of the time, kids with dyslexia aren't recognized until they are about eight or nine. By this time, the level of frustration with reading often creates a self-fulfilling poor reader prophecy. Even after being diagnosed though, the term covers such a range of problems, that it isn't very helpful in developing an Individualized Educational Program. Although dyslexic students all have language processing and learning difficulties in common, the symptoms and severity can be quite different. The most important thing to remember is that is takes time to develop coping strategies, and cannot be cured, as it is a lifelong condition. .
The biological beginnings of dyslexia develops during the first six months of fetal gestation. Neurons are churned out in the brain's ventricular zone.
