Defining Dyslexia

Dyslexia is a specific, language-based learning difference that affects reading, spelling, and writing. It is not a reflection of intelligence or how hard a child tries — it is a difference in the way the brain processes the sounds and structure of language. An estimated 20% of people have dyslexia, making it one of the most common learning differences in the world.

What is dyslexia?

Dyslexia is a neurodevelopmental learning disorder that affects reading, writing, spelling, and sometimes spoken language. The core difficulty is with the way the brain connects letters to the sounds they make, which makes decoding words slow and effortful. It is important to understand dyslexia for what it is — a difference in processing language, not a measure of ability — so we can give children the right support and build a learning environment where they can succeed.

What causes dyslexia?

Dyslexia is believed to have a strong genetic component and often runs in families. It occurs because of differences in the structure and function of the parts of the brain responsible for processing language. In other words, a dyslexic brain is wired to process written language differently — which is also why dyslexia frequently comes paired with real strengths in creativity, problem-solving, and big-picture thinking.

Characteristics and challenges

Children with dyslexia may struggle to decode words, recognize common sight words, and grasp the relationship between sounds and letters. Difficulties with spelling, writing, and reading comprehension are common too. Left unaddressed, these challenges can affect academic performance and self-esteem — but none of them are fixed. For a closer look at what to watch for, see our guide to the signs of dyslexia in children ages 5–10.

How is dyslexia diagnosed?

Diagnosis typically involves a comprehensive assessment by professionals — psychologists, educators, or specialized dyslexia evaluators — who identify a child’s strengths, weaknesses, and specific areas of difficulty. You can request a free evaluation through your child’s public school or pursue a more in-depth private assessment; our guide to dyslexia testing walks through both routes.

Support and interventions

Early identification and intervention are the most important factors in a good outcome. Targeted, structured programs based on the Orton-Gillingham approach improve reading by teaching phonics, decoding, and comprehension explicitly, systematically, and cumulatively. Schools can put an IEP or 504 plan in place with accommodations, and assistive technology like text-to-speech can ease the load. Our dyslexia intervention curriculum turns these methods into lessons parents can teach at home (the workbook is on Amazon).

Empowering a child with dyslexia

Just as important as the academics is the mindset. Celebrate strengths and accomplishments, build resilience, and create a supportive environment that reminds your child their worth isn’t measured by reading speed. Dyslexia is a unique way of processing language — it does not define a child’s intelligence or potential. With the right support, children with dyslexia overcome challenges and bring real talents to the world.
