Are There Different Types of Dyslexia?

Understanding Dyslexia and Co-Occurring Differences
This is one of the most common questions families ask:
“What type of dyslexia does my child have?”
It makes sense. We want clarity. Categories. Something we can point to and understand.
But here’s the truth: Dyslexia is not a collection of separate “types.”
It is a language-based learning difference that primarily impacts:
Phonological processing (how we hear and manipulate sounds)
Decoding (reading words accurately)
Spelling and written expression
What does vary is how it shows up.
Why It Can Feel Like There Are “Types”
No two students with dyslexia look exactly the same.
Some may struggle most with:
Sound awareness (phonemic awareness)
Decoding unfamiliar words
Reading fluency (speed and automaticity)
Spelling patterns
Writing output
Others may appear:
Highly verbal but slow readers
Accurate but very effortful
Strong in comprehension but weak in decoding
These differences are often described as “types,” but they are more accurately: Different profiles within dyslexia.
The Core Issue: The Reading Brain and the Code
At its core, dyslexia is about difficulty connecting:
Sounds (phonemes)
to
Letters (graphemes)
This impacts a child’s ability to:
Break words apart
Blend sounds together
Recognize patterns automatically
Everything else—fluency, spelling, writing—builds from there.
So while the surface may look different, the underlying need is often the same: Explicit, structured instruction in how the code works.
Where Co-Occurring Differences Come In
Here’s where things get more complex—and more important to understand:
Many students with dyslexia also have co-occurring differences.
This is not unusual. In fact, it’s common.
These might include:
ADHD
Dysgraphia
Dyscalculia
Developmental Language Disorder
Anxiety disorders
Each of these can impact learning in different ways—and when they overlap, the student’s experience becomes more layered.
How Co-Occurring Differences Show Up
Let’s look at a few examples:
Dyslexia + ADHD
A student may:
Struggle to sustain attention during reading
Rush through work and make errors
Have difficulty with working memory
This can look like:“They know it… they’re just not applying it.”
But in reality, both attention and reading systems need support.
Dyslexia + Dysgraphia
A student may:
Understand what they want to say
Struggle to get it onto paper
Have messy handwriting or avoid writing altogether
So even when reading improves, writing may still feel like a barrier.
Dyslexia + Anxiety
A student may:
Avoid reading tasks
Shut down quickly
Experience physical symptoms (stomach aches, headaches)
The reading difficulty came first.
But the emotional response has become just as significant.
Patterns You Might Hear About: “Stealth” and “Double Deficit” Dyslexia
You may hear terms like “stealth dyslexia” or “double deficit dyslexia” online or from educators. These aren’t separate diagnoses—but they do describe important patterns within a student’s reading profile.
Stealth Dyslexia
Often used to describe students who:
Appear strong in comprehension
Have advanced vocabulary and verbal reasoning
But struggle with decoding, spelling, or fluency
These students are often missed because:
They sound “on grade level” when discussing text
They compensate well using context and memory
Until the workload increases—and the gap becomes harder to hide.
Double Deficit Dyslexia
This refers to students who struggle with both:
Phonological processing (sound awareness)
and
Rapid automatic naming (how quickly they can retrieve and produce known information, like letters or numbers)
These students often:
Read accurately but very slowly
Have difficulty building reading fluency
Require more repetition to build automaticity
These terms can be helpful for understanding patterns—but they don’t change the most important next step: Targeted, explicit instruction based on your child’s actual skill profile.
Why This Matters for Support
If we only address one piece, we miss the full picture. A student with dyslexia and ADHD doesn’t just need reading intervention.A student with dyslexia and anxiety doesn’t just need reassurance.
They need integrated support that considers:
Skill development
Executive functioning
Emotional experience
Because learning doesn’t happen in isolated systems.
The Risk of Oversimplifying
Sometimes we hear:
“They just need phonics”
“They just need accommodations”
“They just need confidence”
But for many students, it’s not just one thing.
Oversimplifying leads to:
Partial progress
Continued frustration
Missed opportunities for real growth
Understanding the full profile leads to:
More targeted instruction
Better alignment across supports
Stronger outcomes over time
What Stays Consistent
Even with different profiles and co-occurring differences, one thing remains true:
Students with dyslexia benefit from:
Explicit, systematic reading instruction
Clear routines and repetition
Opportunities to apply skills in meaningful ways
That foundation doesn’t change. What changes is how we layer support around it.
Educator Insight
When students present with complex profiles, it’s essential to:
Separate decoding from comprehension in assessment
Look at patterns across reading, writing, and attention
Avoid assuming one difficulty explains everything
Targeted screening and ongoing progress monitoring help ensure:
Instruction matches the need
Interventions are adjusted as needed
Growth is measured accurately
Parent Power Move
If your child has been identified with dyslexia—or you suspect it—ask:
“Are there other factors impacting their learning?”
“Do we understand their full profile?”
“Is their instruction aligned to all areas of need?”
You don’t need ten different programs. But you do need a clear, coordinated plan.
Final Thought
Dyslexia doesn’t exist in a vacuum. And your child is not a checklist of labels. They are a whole learner—with strengths, challenges, and a unique way of processing the world.
The goal isn’t to perfectly categorize them. It’s to understand them well enough to teach them effectively. Because when we see the full picture—
We can finally build support that works.
