Dyslexia is the most common cause of struggles in reading, yet it is widely misunderstood and effective help can be very difficult to find.
Dyslexia is a difference in how people learn and process information. You cannot change how a dyslexic person processes information to make them fit into the box of traditional education. The solution is to understand what makes it hard for them to learn reading as it is usually taught and start teaching them differently, using a system designed with them specifically in mind.
There is a lot to learn about dyslexia, but this 5-minute TED video is an excellent introduction.
Did you catch that quote towards the end? "Those with dyslexia can physically change their brain and improve their reading. With an intensive multisensory intervention that breaks the language down and teaches the reader to decode based on syllable types and spelling rules, the brains of those with dyslexia begin using the left hemisphere more efficiently while reading, and their reading improves. The intervention works because it locates dyslexia appropriately, as a functional variation within the brain."
That quote describes perfectly what the system we use is designed to do.
