Dyslexia is a very broad term defining a learning disability that impairs a person's fluency or comprehension accuracy in being able to read, and which can manifest itself as a difficulty with phonological awareness, phonological decoding, orthographic coding, auditory short-term memory, or rapid naming. Dyslexia is separate and distinct from reading difficulties resulting from other causes, such as a non-neurological deficiency with vision or hearing, or from poor or inadequate reading instruction. It is believed that dyslexia can affect between 5 and 10 percent of a given population although there have been no studies to indicate an accurate percentage.
The first thing that needs to be said is that dyslexia is not brought about by poor parenting. On the contrary, it is the concerned parents of dyslexic children who have taken the initiatives that have brought dyslexia to the forefront of the learning difficulties arena.
Individual parents have persisted in pointing out to their children's schools that something must be wrong when a child of apparently normal intelligence is failing to learn to read and write.
