Decoding Dyslexia: What Dyslexia Actually Is (and Isn't)

 What Dyslexia Actually Is (and Isn't)

This chapter explores the true nature of dyslexia, defining it not as a lack of intelligence but as a specific neurological difficulty with processing the sounds of language. The author emphasizes that dyslexia frequently occurs alongside dysgraphia and ADHD, creating a complex set of challenges that traditional schooling often fails to address. A central theme is the danger of simplifying educational content for these students, as lowering the intellectual bar ignores their high level of listening comprehension and verbal reasoning. Through personal anecdotes, the source illustrates how passionate teaching and high-interest materials, like complex games, act as essential tools for engagement. Ultimately, the narrative advocates for a specialized instructional approach that repairs the "bridge" of decoding while still honoring the child's sophisticated inner world.

LONG-FORM PODCAST

Decoding the Bridge: The Dyslexic Mind Explained SLIDE DECK

Before we go any further, I need to stop and speak to you directly — not as a memoirist arranging scenes from a safe distance, but as someone who sat where your child is sitting. If you are a parent who has recently heard the word dyslexia in a school meeting, or a teacher who has a student whose intelligence is obvious but whose page is a battlefield — this chapter is for you. What I am about to describe is not a tragedy. But it has been badly misunderstood, and that misunderstanding has cost children years they did not have to lose.

 

The Diagnosis

I was diagnosed at the end of fourth grade. A school psychologist administered a battery of tests, and the results came back with a single word attached to them. Dyslexia.

At the time, the diagnosis was only dyslexia. Dysgraphia — the writing and fine motor component that explained why my handwriting looked like a seismograph during an earthquake, why I couldn't spell words I could define with precision, why the act of putting thought onto paper felt like trying to carry water in my hands — that came later, named separately, as though the two weren't obvious companions.

They almost always are.

Dyslexia rarely arrives alone. It comes with company — most commonly dysgraphia, and frequently an overlap with ADHD. Each of these is a separate condition with its own profile, its own strengths, its own particular way of making school feel like a building designed for someone else's body. But they cluster. And a child carrying more than one of them into a classroom is navigating a compound difficulty that most instruction is not designed to address.

What the diagnosis gave me was a name. What it did not give me — what it took years and a career in special education to understand — was an accurate picture of what the name actually meant.

 

What the Word Actually Means

Dyslexia is a phonological processing disorder. That is the clinical description, and it matters that we get it right, because the wrong description has been doing damage for decades.

Phonological processing is the brain's ability to hear, identify, and manipulate the individual sounds — phonemes — that make up spoken words. It is the system that allows you to know, without thinking about it, that "cat" has three sounds, that "sh" is different from "s," that "bat" and "bad" differ by one phoneme at the end. For most people this system operates automatically, beneath the level of conscious awareness. For people with dyslexia, it doesn't. The mapping between written letters and the sounds they represent — the alphabetic principle, the foundational mechanism of decoding — is where the breakdown occurs.

This is not a vision problem, though it has been described as one. It is not a matter of seeing letters backwards — though reversals are common and add to the confusion. It is not a problem of intelligence. It is not laziness, inattention, or a failure of effort. It is a specific, neurological difference in how the brain processes the sound structure of language.

The page is not the problem. The bridge between the sound of a word and the symbol on the page — that is where dyslexia lives.

This distinction matters enormously, because the instructional response to a decoding problem is completely different from the instructional response to a comprehension problem or an intelligence problem. A child who cannot decode is not a child who cannot understand. They are a child who cannot yet access the print. The understanding is there. The language is there. The bridge is not.

 

The Mistake That Costs Years

The most damaging error adults make with dyslexic children is to treat a decoding deficit as a global deficit — to read the broken bridge as evidence that there is nothing on the other side.

I saw this as a teacher for twenty-six years. I see it in my own story. A child who cannot read a grade-level passage is given below-grade-level material. The below-grade-level material has below-grade-level vocabulary, below-grade-level syntax, below-grade-level ideas. The child, who may have a listening comprehension level two or three or five years above their grade, is handed a book about a running dog. And something in that child — something precise and corrosive — begins to believe that the running dog is all they are worth.

That is not remediation. That is confirmation of a lie.

The basal reader, calibrated to the decoding level, assumes the child needs simplified language across the board. But a child with dyslexia and strong oral language processing doesn't need simpler language — they need the bridge repaired while the city stays intact. The moment we simplify the language to match the decoding level, we stop building the listening comprehension that will eventually meet the decoded word on the other side. We have the equation backwards.

I called this feeling, in my own childhood, being a child of a lesser God. That phrase comes from a film, but it captured something precise about the emotional experience — the sense of being spoken to in a register that assumed your limitations rather than your potential, of being given less because less was expected, of watching the ceiling get installed directly overhead.

The ceiling is not structural. It is a choice. And it can be removed.

 

◆  THE CLINICAL PICTURE: DYSLEXIA, DYSGRAPHIA, AND ADHD

Every child with a learning difference presents on a spectrum. No two profiles are identical. What follows is not a checklist for diagnosis — diagnosis requires qualified evaluation — but a recognition guide: the kinds of things that show up, often in combination, in children whose learning needs are not being met by standard instruction.

 

Dyslexia · Dysgraphia · ADHD Overlap

The table below outlines common presentations across the three most frequently co-occurring conditions. A child may show traits from one column, two, or all three. The overlap is not coincidence — these conditions share neurological underpinnings and frequently travel together.

 

 

Dyslexia	Dysgraphia	ADHD Overlap
Difficulty decoding printed words	Illegible or inconsistent handwriting	Difficulty sustaining attention on tasks
Slow, effortful reading; loses place on page	Slow, labored writing pace	Easily distracted by environment or internal thoughts
Phonological processing weakness	Poor spelling — even of familiar words	Impulsivity; acting before thinking
Letter and word reversals (b/d, was/saw)	Inconsistent letter formation and sizing	Difficulty with organization and planning
Difficulty rhyming or segmenting sounds	Omits letters, words, or punctuation when writing	Working memory challenges
Avoids reading aloud; guesses from context	Difficulty translating thought into written form	Emotional dysregulation; low frustration tolerance
Strong listening comprehension despite weak decoding	Fine motor coordination difficulties	Often co-occurs with dyslexia (30–50% of cases)
Often stronger in math reasoning than computation	Fatigue from extended writing tasks	Strengths in creative thinking and hyperfocus
Memory for faces and places; weak for names and words	Can draw or create visually what they cannot write	High energy and divergent thinking when engaged

 

On the Spectrum

Each of these conditions exists on a continuum. A child with mild dyslexia may decode slowly but eventually get there; a child with severe dyslexia may struggle to decode at all without intensive, structured intervention. Dysgraphia ranges from inconsistent spelling and poor handwriting to a near-complete inability to produce legible written work. ADHD manifests differently in different nervous systems — and differently in boys versus girls, a distinction that has historically led to significant underdiagnosis in girls.

The spectrum also means that strengths vary. Many children with dyslexia are exceptional verbal reasoners, spatial thinkers, and creative problem-solvers. Many children with dysgraphia are gifted visual artists — the same hand that cannot form letters can draw with precision and feeling. Many children with ADHD have the capacity for intense, sustained focus when engaged with something that genuinely interests them. The deficit is real. So is the asset.

What Good Assessment Looks Like

A thorough evaluation for a child suspected of having dyslexia should include, at minimum: a measure of phonological processing, a measure of decoding (both real words and nonsense words), a measure of reading fluency, and — critically — a measure of listening comprehension. That last assessment is frequently omitted. It should not be. The gap between a child's listening comprehension level and their decoding level is not a footnote. It is the central diagnostic finding, and it should drive every instructional decision that follows.

I tested for both as a matter of course throughout my teaching career. The spread, in children with dyslexia, was almost always striking. A student decoding at a first-grade level who comprehends at a fifth-grade level when listening is not a struggling learner who needs simpler input. They are a child who needs a better bridge — and a richer city waiting on the other side while that bridge is under construction.

 

 

Mr. Green and the Lizards

I want to tell you about two teachers, because they are evidence of something the science confirms but cannot fully capture: that a teacher's passion is a form of instruction.

Maxwell Junior High, Tucson, Arizona. Seventh or eighth grade. Science class, Mr. Green.

Mr. Green was a large, gregarious man with a blonde Afro and a classroom that looked like a pet shop had lost an argument with a natural history museum. There were lizards. There were snakes. There were amphibians in tanks along every wall, and the room had the particular warm, slightly wild smell of a place where living things were being cared for. We did not spend much time in the books. We moved through that classroom the way you move through a habitat — with curiosity, with attention, with the low-level alertness of someone who might, at any moment, discover something remarkable.

Mr. Green brought a love of biology so specific and so genuine that it was contagious in the way that only authentic things are. He didn't teach us to love science. He simply loved it in front of us, loudly and without apology, and we caught it the way you catch a cold — without deciding to.

In his room, there were no barriers. There were no written tasks standing between me and the knowledge. There was no moment where my inability to decode a paragraph announced, to the room, what was wrong with me. There was only the lizard, and the question, and the man who had devoted his life to knowing the answer.

I thrived. Not because my dyslexia had been remediated. Because it had been made irrelevant.

 

The social studies teacher — I cannot remember his name, and I should explain that this is not carelessness but neurology; names have always been the most fleeting thing in my memory, a particular cruelty for a person who otherwise retains language so precisely — was cut from similar cloth, though his passion took him to a different hemisphere.

Every summer, he loaded a touring bike and disappeared into the world. Peru. Europe. The American Southwest. He came back with stories, and on Fridays he shared them. Not from a textbook. Not from a worksheet. From his own body, his own road, his own accumulated catalogue of beautiful problems.

He talked about living on peanut butter for two weeks in the Andes. About the specific mechanical failure of a derailleur at high altitude when you are three days from the nearest town. About how the worst stories, in retrospect, were always the best ones — because difficulty, survived, becomes material.

I did not know then that I would eventually travel to many countries and discover that this was true. I knew it in his classroom, in the way you know things before you have the evidence: as a feeling in the chest that says this is real, this is worth something, pay attention.

Both of these men understood, perhaps without articulating it, what the research now confirms: engagement is not a reward for learning. It is the condition that makes learning possible. When a child is genuinely interested — when the material connects to something that already lives in them — the cognitive load of decoding, of written expression, of all the things that are hard, becomes temporarily manageable because the motivation to get through it is real.

For a child with dyslexia, a teacher with passion is not a luxury. It is a ramp.

 

The Coping Mechanisms Nobody Talks About

Here is something the clinical literature handles carefully and the memoirs often sanitize: children with dyslexia become extraordinarily resourceful in ways that are not always admirable.

I memorized books that were read aloud and performed reading by running my finger along the lines at the right pace. I cultivated a carefully maintained persona of the verbally gifted, slightly eccentric kid — the one whose vocabulary compensated, socially, for the disaster on the page. I used my skills of oration to turn F's into D's: a detailed, impassioned account of how many schools I had attended, how the constant moves had left gaps in my education, how my learning disability made written communication genuinely difficult — delivered directly to the teacher, with eye contact, without notes.

It worked more often than it should have.

I got people to do things for me. Not out of malice, but out of survival. If a written task stood between me and something I needed, I found someone who would help me with it — and I was persuasive enough, and genuinely grateful enough, that this usually worked. I learned early that oration was currency. That if you could make a room listen, you could sometimes trade listening for accommodation.

I am not recommending this. I am describing it accurately, because if you are raising or teaching a child with dyslexia and you have noticed that they are, somehow, more capable of talking their way around a problem than solving it directly — that is not a character flaw. That is a child who has identified their strongest tool and is using it. The job of the adult in the room is to make sure that tool doesn't become the only one they have.

The D&D box set arrived when I was in fifth or sixth grade. I cannot read the rulebooks. I carry them anyway.

My uncle gave me the Dungeons and Dragons box set. I don't know exactly how old I was — fifth birthday, sixth, somewhere in that territory. What I know is that I could not read the rulebooks, and I desperately wanted to. Not because someone told me I should. Because the maps were extraordinary, the illustrations were extraordinary, and somewhere inside that dense, complicated text was an entire world that I could not yet access.

That wanting — that specific, acute desire to crack the code of a page because something worth having was on the other side of it — was more powerful than any reading intervention I ever received. The scientists call it motivation. The teachers call it engagement. I call it the moment I actually wanted to learn to read.

Nobody gave me a running dog. They gave me a dragon. And I went looking for the bridge.

 

Reading is not one skill wearing a single name. It is two skills, and only one of mine was broken.

In the assessment of a child suspected of having dyslexia, a measure of listening comprehension is considered critical because it reveals the true extent of a child's language processing and intellectual potential, which is often masked by their inability to decode printed text.

According to the source, listening comprehension is vital for the following reasons:

• It is the "Central Diagnostic Finding": The gap between a child’s listening comprehension level and their decoding level is not just a detail; it is the most significant finding in a dyslexia evaluation. This "spread" can be striking—for example, a student might decode at a first-grade level but comprehend at a fifth-grade level when listening.
• It Distinguishes Between Decoding and Intelligence: Dyslexia is a specific neurological difference in processing the sound structure of language, not a problem of intelligence or understanding. Assessment of listening comprehension proves that the "understanding is there" and the "language is there," but the "bridge" to the print is simply broken.
• It Prevents "Global Deficit" Assumptions: The source notes that the most damaging error adults make is treating a decoding deficit as a "global deficit"—assuming that because a child cannot read a grade-level passage, they cannot handle grade-level ideas. Without measuring listening comprehension, schools may mistakenly provide "below-grade-level material" with simplified vocabulary and syntax, which leads the child to believe they are less capable than they actually are.
• It Drives Proper Instructional Strategy: Understanding a child's listening level ensures they are given "richer" information and high-level ideas while they work on repairing their decoding skills. If language is simplified to match a low decoding level, it stops the development of the very comprehension skills that the child will eventually need once they learn to decode.

Ultimately, assessing listening comprehension ensures that the child is seen as a "child who needs a better bridge" rather than a "struggling learner who needs simpler input".

While the sources do not provide a side-by-side formal definition for both terms, they distinguish between them as separate components of a thorough reading assessment and describe their roles in the reading process.

Decoding

Decoding is described as the foundational mechanism of the "alphabetic principle"—the ability to map written letters to the individual sounds (phonemes) they represent. It is a phonological processing task where the brain hears, identifies, and manipulates sounds to translate symbols on a page into spoken language. The sources characterize decoding as the "bridge" between the sound of a word and its visual symbol. In a clinical evaluation, decoding is typically measured using both real words and "nonsense words" to ensure the student is actually applying phonetic rules rather than relying on memory.

Reading Fluency

Reading fluency is treated as a separate measure from decoding in a professional evaluation. While decoding focuses on the mechanics of sound-symbol association, fluency relates to the ease and speed of the reading process. The sources associate a lack of fluency with the following characteristics often seen in dyslexic students:

• Slow, effortful reading.
• Losing one’s place on the page while reading.
• Fatigue resulting from the high cognitive load of the task.

The Key Difference

The fundamental difference lies in their roles: decoding is the tool used to "crack the code" of the text, while fluency is the result of that tool working efficiently and automatically. A child with dyslexia may eventually learn to decode (the "bridge"), but if the process remains "slow and effortful," they will still struggle with fluency. The sources emphasize that because these are different skills, a "thorough evaluation" must include specific, distinct measures for both decoding and reading fluency to create an accurate picture of a student's needs.

Dyslexia and dysgraphia frequently occur together because they share common neurological underpinnings and are part of a cluster of related learning differences. While they are distinct conditions with their own specific profiles, their co-occurrence is not a coincidence.

Key reasons for their frequent overlap include:

• Shared Neurological Roots: The sources state that these conditions "frequently travel together" because they originate from related differences in how the brain processes information.
• The "Cluster" Effect: Dyslexia rarely arrives alone; it is part of a spectrum of learning differences that often includes dysgraphia and ADHD. A child navigating one of these conditions is statistically more likely to be navigating others within this "compound difficulty".
• Complementary Deficits: While dyslexia is a phonological processing disorder affecting the "bridge" between sounds and symbols (decoding), dysgraphia involves the writing and fine motor component. A student may struggle with the sounds of language (dyslexia) while also experiencing a "breakdown" in the physical act of putting those thoughts onto paper (dysgraphia).
• Related Symptom Profiles: The overlap is often visible in the classroom. For instance, a student might have difficulty with spelling—which is a hallmark of both dyslexia (due to phonological weakness) and dysgraphia (due to inconsistent letter formation and sizing).

Because of this frequent overlap, the sources suggest that a thorough evaluation should look at the child's complete profile rather than treating each diagnosis as an isolated incident.

A thorough evaluation for a child suspected of having dyslexia must go beyond a simple reading test and should include, at minimum, the following components:

• Phonological Processing: This measures the brain's ability to hear, identify, and manipulate the individual sounds (phonemes) that make up spoken words. This is considered the foundational mechanism of the "alphabetic principle".
• Decoding (Real and Nonsense Words): An assessment must measure the ability to map written letters to sounds. It is critical to include nonsense words to ensure the student is actually applying phonetic rules (the "bridge" to print) rather than relying on their visual memory of familiar words.
• Reading Fluency: This is treated as a separate measure from decoding. While decoding focuses on mechanics, fluency assessments measure the ease, speed, and automaticity of the reading process to identify if reading is slow, effortful, or causing high levels of fatigue.
• Listening Comprehension: Often omitted, this is described as the "central diagnostic finding" in a thorough evaluation. Measuring the "spread" between a child's high listening comprehension and their low decoding level proves that the child has the language and intelligence but lacks the "bridge" to access printed text.
• Screening for Co-occurring Conditions: Because dyslexia "rarely arrives alone," a qualified evaluation should look for a cluster of related conditions, most commonly dysgraphia (writing and fine motor difficulties) and ADHD.

The goal of this comprehensive approach is to create an accurate picture of the student's needs, ensuring that a "decoding deficit" is not mistaken for a "global deficit" in intelligence or understanding.

Labels like “learning disabled,” “dyslexic,” or “dysgraphic” can feel more like anchors than supports when they define a child’s limits instead of their potential. What truly matters is not the label, but the learning environment we create around it.

For many students, traditional assessments—especially written exams—act like barriers rather than measures of understanding. Asking every child to demonstrate knowledge in the same way is like asking everyone to run a marathon, regardless of physical ability. When a child struggles with decoding or writing, it does not mean they struggle with thinking.

The role of the teacher is not to enforce barriers in the name of grades or data, but to remove them so learning can flourish. When those barriers are lifted, something remarkable happens: curiosity returns, confidence grows, and learning becomes joyful again.

We must shift our mindset. The goal is not compliance with rigid assessment systems, but access to meaningful learning. When we prioritize understanding over format, all students—especially those with dyslexia or dysgraphia—can engage deeply, think critically, and succeed.

Explaining This for Parents

A dyslexia diagnosis can feel overwhelming at first, but it is important to separate how a child learns from how intelligent they are. Dyslexia affects decoding (reading words), not thinking, reasoning, or creativity.

Many school systems still rely heavily on written output to measure learning. This can unintentionally mask what a child actually knows. A child who struggles to read or write quickly may still:

• Understand complex stories and ideas

• Think abstractly and philosophically

• Solve problems creatively or logically

The key shift for parents is this: your child does not need to be “fixed” to learn deeply—they need access to learning in ways that work for their brain.

An example:
A child who cannot easily write a paragraph about a historical event may be able to explain it brilliantly in conversation, build a model, or create a visual timeline.

---

Fostering Deep Engagement with Big Ideas

Even with decoding challenges, children can engage with rich, high-level content if access is adjusted.

• Use audiobooks and read-alouds for complex texts (mythology, history, philosophy).

• Prioritize discussion over written response; use Socratic questioning at home.

• Allow verbal narration instead of written summaries.

• Use visuals: timelines, diagrams, mind maps, and sketches.

• Integrate storytelling and role-play to explore historical or literary ideas.

• Encourage questioning: “Why do you think that happened?” or “What would you do?”

• Pair reading with listening (follow along with text while hearing it).

• Use assistive technology (text-to-speech, speech-to-text).

• Break large texts into smaller, meaningful chunks without simplifying ideas.

• Focus on ideas first, mechanics second.

The goal is to ensure the child is still encountering rich, complex thinking, even if the pathway is different.

---

Nurturing Creative and Logical Strengths Daily

Children with dyslexia often show strong abilities in pattern recognition, storytelling, systems thinking, and creativity. These can be developed intentionally.

• Ask open-ended questions during daily routines (e.g., “How would you solve this problem?”).

• Encourage building activities (LEGO, models, engineering kits).

• Use drawing or sketching to express ideas instead of writing.

• Play strategy games (chess, logic puzzles, problem-solving apps).

• Invite storytelling aloud—fictional or real-life recounting.

• Explore interests deeply (dinosaurs, space, history, mechanics).

• Use project-based learning (create a mini museum exhibit, design a city, etc.).

• Celebrate effort in thinking, not just correctness or neatness.

• Allow choice in how they show learning (talk, build, draw, act).

• Keep a “strength journal” where you note what they do well each day.

An example:
If a child struggles to write sentences but can explain how a machine works in detail, that is a logical strength worth developing, not a gap to ignore.
