What is Dyslexia

Dyslexia is a specific learning difference that primarily affects reading, spelling, and writing. It is neurobiological in origin and unrelated to intelligence, vision problems, or lack of educational opportunities. People with dyslexia typically have difficulty with accurate and/or fluent word recognition and often struggle with decoding words (sounding them out) and spelling. These challenges result from differences in how the brain processes language, particularly phonological processing—the ability to recognize and manipulate the sounds of spoken words.

How Common is Dyslexia?

Dyslexia is one of the most common learning differences, affecting approximately 5–15% of the population, depending on how broadly it is defined. It exists on a spectrum, meaning that individuals may experience it in mild, moderate, or severe forms. It is lifelong but manageable with proper support and teaching strategies. Early identification and intervention, especially in the early grades, can make a significant difference in helping dyslexic students achieve reading fluency and academic success.

What is dyslexia NOT?

It is important to understand what dyslexia is not. Dyslexia is not a sign of low intelligence or laziness. In fact, many people with dyslexia are highly intelligent and creative, often excelling in areas like problem-solving, storytelling, spatial reasoning, and entrepreneurship. It is also not caused by poor teaching, bad parenting, or visual problems like seeing letters reversed. While people with dyslexia might confuse letters such as "b" and "d" when learning to read, the myth that they “see letters backwards” is a misunderstanding of the actual condition.

Another common misconception is that dyslexia can be “cured.” Because it is a neurological difference, there is no cure—but with the right instruction, especially structured literacy programs based on the science of reading, individuals with dyslexia can learn to read well. These programs emphasize phonemic awareness, phonics, vocabulary, fluency, and comprehension, and they are often taught in a systematic, explicit, and multisensory way. 

Dyslexia is not limited to English speakers or alphabetic languages. It occurs across languages and cultures, although it may appear differently depending on the language’s structure. For instance, dyslexia might be less noticeable in languages with more transparent spelling rules, like Italian or Finnish, but it still involves challenges with rapid word retrieval and phonological processing.

It is also important to distinguish dyslexia from other learning differences or attention disorders. While it can co-occur with conditions like ADHD or dysgraphia (difficulty with writing), dyslexia is specifically a language-based issue. Proper diagnosis by trained professionals—often through educational psychologists or specialized learning evaluators—is essential to provide accurate support.
