What Is Dyslexia?

By Virginia Lindahl, PhD

Your daughter has always been curious and bright. She asks thoughtful questions, loves being read to, and can explain complicated ideas with surprising insight. But when it’s her turn to read aloud, she stumbles over words that seem familiar. Homework that involves reading takes much longer than it seems like it should, and spelling tests become a source of frustration despite hours of studying.

Or maybe your child understands classroom discussions, enjoys science, and performs well in conversations, yet reading remains slow, effortful, and exhausting. Teachers tell you he’s capable of more, but his reading doesn’t seem to reflect what he knows.

For many families, this disconnect is confusing. How can a child be so intelligent and still struggle to read?

One possible explanation is dyslexia.

What Is Dyslexia?

Dyslexia is a learning disorder that primarily affects reading. It makes it more difficult to recognize written words accurately and fluently despite adequate instruction and learning opportunities.

Dyslexia isn’t a problem with intelligence, motivation, or effort. Children with dyslexia are often bright, hardworking, and eager to learn. The difficulty lies in the brain processes that support learning to recognize and read words efficiently.

Reading may remain slow, effortful, or inaccurate long after classmates have become fluent readers.

What Does Dyslexia Look Like?

Dyslexia doesn’t look the same in every child, but many parents notice similar patterns.

A girl may guess at unfamiliar words based on the first few letters instead of sounding them out completely. She may skip small words while reading aloud or lose her place on the page. Reading assignments often take much longer than expected, and she may avoid reading simply because it requires so much effort.

A boy may understand stories perfectly when someone reads to him but struggle to read the same material independently. He may remember fascinating facts from documentaries or class discussions yet have difficulty reading a chapter in a textbook.

As children get older, the struggles often become less about learning to read and more about reading to learn. Even when a child understands language well, slow and effortful reading can make it harder to keep up with longer assignments and remember what was read. Because reading requires so much effort, completing homework, studying for tests, and keeping up with classroom assignments can become increasingly difficult.

Common Signs of Dyslexia

Although every child is different, these are some of the most common signs of dyslexia:

  • slow or effortful reading

  • difficulty sounding out unfamiliar words

  • frequent reading mistakes

  • poor reading fluency

  • inconsistent spelling

  • avoiding reading whenever possible

  • becoming tired during reading tasks

  • understanding information much better when it is heard than when it is read

  • frustration or declining confidence related to reading

These signs and symptoms often become more noticeable as reading demands increase.

A child doesn’t need to show every one of these signs to have dyslexia.

Dyslexia Is More Than Reversing Letters

One of the most common myths about dyslexia is that children see letters or words backwards.

Although young children with and without dyslexia sometimes reverse letters such as b and d, this isn’t what defines dyslexia. In fact, letter reversals are neither necessary nor sufficient for a diagnosis.

The core difficulty involves learning to recognize written words accurately and efficiently. The defining difficulty is learning to recognize written words accurately and automatically. As reading becomes more effortless for most children, students with dyslexia often continue relying on slow, effortful decoding.

Why Reading Becomes So Difficult

Reading feels effortless to skilled readers because the brain gradually learns to recognize many words automatically.

For children with dyslexia, that process develops less efficiently.

Instead of recognizing a word almost instantly, a student may need to stop, sound it out, try again, and think carefully before identifying it. This happens over and over again throughout a reading assignment.

As a result, reading requires far more mental effort. By the end of a chapter, a child may be mentally exhausted even though classmates completed the same assignment with much less effort.

Dyslexia Doesn’t Mean a Child Isn’t Smart

One of the most harmful misconceptions about dyslexia is that it reflects low intelligence.

It doesn’t.

Many children with dyslexia have average, above-average, or gifted intellectual abilities. They often excel in conversation, problem-solving, creativity, reasoning, science, engineering, art, or other areas that don’t depend heavily on reading.

Because of this, parents are often surprised when testing reveals a reading disorder. The child’s intelligence may have helped compensate for reading difficulties for years, making the problem harder to recognize.

As children get older, however, stronger reasoning abilities and hard work often aren’t enough to keep up with increasing reading demands. Assignments become longer, textbooks become more complex, and reading speed becomes increasingly important. As a result, the gap between what a child knows and what she can demonstrate through reading may become more noticeable over time.

Different Types of Dyslexia

Not all dyslexia looks the same.

Some children have greater difficulty connecting letters with speech sounds. Others struggle primarily to recognize familiar words quickly and automatically, even after repeated practice.

These different patterns are sometimes described as phonological dyslexia and orthographic dyslexia. Although the underlying difficulties differ, both can significantly interfere with reading fluency and academic performance.

Understanding a child’s specific pattern of strengths and weaknesses helps guide intervention and educational recommendations.

How Is Dyslexia Diagnosed?

A comprehensive evaluation looks beyond whether a child is reading below grade level.

Testing typically examines reading accuracy, reading fluency, reading comprehension, phonological processing, rapid naming, spelling, and other skills that contribute to successful reading. The evaluation also considers cognitive abilities, educational history, and classroom functioning.

The goal isn’t simply to determine whether a child meets criteria for dyslexia. It’s to understand why reading is difficult and identify the supports that are most likely to help.

Can Dyslexia Improve?

Yes.

Dyslexia doesn’t simply disappear with age, but children can make meaningful progress with appropriate intervention.

Evidence-based reading instruction, appropriate school accommodations, and targeted support can lead to meaningful improvements in reading skills while helping children develop confidence and succeed academically.

Early identification is often helpful, but older students and adults can also benefit from understanding their learning profile and receiving appropriate support.

Some people aren’t diagnosed until adolescence or adulthood, particularly if strong reasoning abilities, good memory, or extra effort helped them compensate during earlier school years.

When Should Parents Consider Testing?

Parents often seek an evaluation when reading remains unexpectedly difficult despite good instruction and consistent effort.

You might consider testing if your child:

  • reads much more slowly than classmates

  • struggles to sound out unfamiliar words

  • has persistent spelling difficulties

  • avoids reading because it feels frustrating or exhausting

  • performs much better when information is presented verbally

  • seems much more capable than reading performance would suggest

An evaluation can help determine whether dyslexia, another learning disorder, ADHD, or another factor is contributing to your child’s difficulties.

Dyslexia Testing in Arlington, VA

I provide comprehensive psychoeducational evaluations for children and adolescents experiencing reading, learning, attention, and academic difficulties. Evaluations are designed to identify patterns of strengths and weaknesses, clarify whether dyslexia or another learning disorder may be contributing to a child’s struggles, and provide practical recommendations for school and home.
