Too succeed in school, children must master three skills - reading, writing and arithmetic - but not all students readily grasp these basic skills. Among English-speaking children, an estimated 2 to 15% have trouble with reading or spelling, broadly classified as dyslexia. From 1 to 7% struggle to do math, a disability known as dyscalculia. Statistics vary but dyslexia appears to be more common among English speakers than among speakers of highly phonetic languages such as Turkish and Italian. It is believed that at least one child in most elementary school classes in the US suffers from dyslexia. Both dyslexia and dyscalculia defy easy explanation. Neither disorder is the result of faulty eyesight nor hearing, both of which can also delay language acquisition but are easily connected. Instead, children with dyslexia and dyscalculia have working sensory organs, apparently normal sensory and motor development and, sometimes, above - average intelligence. After more than 15 years of research, investigators now believe these conditions frequently involve so called partial functional deficits of the senses. In affected children, the eyes and ears accurately register sights and sounds, letters, numbers and spoken syllables, but that information is misinterpreted as it is processed in the brain.
