Though Myomancy.com focuses non-language / education based methods of dealing with dyslexia its worth remembering that there are more traditional approaches that work. One of these is the Orton-Gillingham Multisensory Method. It is a phonics based program taught one-to-one in a manner that suits how most dyslexic people learn, i.e. multi-sensory with a slow, steady step-by-step approach. There is a more in-depth write up of here. This comes from an informative web site called Bright Solution for Dyslexia.
The Orton-Gillingham approach is used or has been adapted by a number of individual teachers and centres around the country. One of the biggest is Lindamood-Bell who have centres all over the US and one in the UK.
