An Interesting Aside: Neurologically speaking, Dyslexia presents differently for different kinds of written language. The most commonly written modern non-alphabetic language is, of course, Chinese. Chinese uses a logographic writing system, wherein each glyph represents a syllable, which can have meaning on its own or can be combined with other glyphs to make more complex meaning. Glyphs may include phonographic markers, pictographic markers and ideographic markers, but the system itself is considered logographic. And decoding logographic writing utilizes a different part of the brain than used while decoding a phonetic alphabet.
So while dyslexia exists in both Chinese and English, it is a result of issues in different parts of the brain.
In other words, someone dyslexic in English is not dyslexic in Chinese, and vice versa.
