ADHD and Dyslexia: When Two Learning Differences Overlap

Two Conditions, One Very Frustrated Brain

If reading has always been harder than it should be, if words swim on the page, if you have to re-read paragraphs multiple times, if spelling is a constant battle despite being perfectly intelligent, you might have dyslexia. And if you also have ADHD, you are not alone in having both.

Research by Germanio et al. (2010, Cortex) and DuPaul et al. (2013, Journal of Learning Disabilities) has consistently shown a significant overlap between ADHD and dyslexia, with estimates of co-occurrence ranging from 25% to 40%. That is a substantial number of people managing two neurodevelopmental conditions that affect reading, learning, and daily life in different but compounding ways.

How ADHD and Dyslexia Are Different

The distinction matters because they need different strategies:

The key distinction: ADHD affects whether you can pay attention to text. Dyslexia affects whether you can decode it. When you have both, reading becomes a double challenge because you are fighting to stay focused AND fighting to process the words themselves.

Why They Get Confused

ADHD and dyslexia are frequently mistaken for each other, which leads to people getting support for the wrong condition:

• A child who cannot sit still during reading time might be labelled as having a behaviour problem (ADHD) when they are actually struggling to decode the words (dyslexia) and moving because they are frustrated
• A student who does not complete reading assignments might be diagnosed with dyslexia when the real issue is ADHD-related executive dysfunction
• An adult who re-reads paragraphs constantly might assume it is dyslexia when it is actually ADHD inattention causing them to lose track

When both are present, it is even more confusing. The person might get diagnosed with whichever condition is more obvious, while the other goes undetected and untreated.

How They Make Each Other Worse

When ADHD and dyslexia co-occur, they compound each other in specific ways:

Reading becomes exhausting. Decoding words already requires more cognitive effort with dyslexia. Adding ADHD means you cannot sustain the already-high level of concentration required. Result: you might read for five minutes before your brain gives up entirely.

Writing is doubly hard. ADHD makes it hard to organise thoughts and maintain focus on the writing process. Dyslexia makes the mechanical act of writing (spelling, sentence construction, getting words from brain to page) effortful. Together, writing anything can feel like an insurmountable task.

Self-esteem takes a double hit. Both conditions are associated with academic difficulty and negative feedback from teachers and parents. Having both means you have been told from multiple angles that you are not good enough, not trying hard enough, not smart enough. The self-esteem damage from this dual experience can be profound.

Learning strategies conflict. Dyslexia strategies often involve repetition, structured phonics work, and careful, methodical practice. ADHD brains rebel against repetition and methodical practice. Finding learning approaches that work for both conditions requires creative adaptation.

Strategies That Work for Both

1. Audio First

If reading is a battle on two fronts, use your ears instead. Audiobooks, text-to-speech software, podcasts, and video content can bypass both the decoding difficulty and the sustained reading attention problem. This is not cheating, it is using the input channel that works best for your brain.

2. Assistive Technology

There are excellent tools designed for exactly this overlap:

• Text-to-speech (Natural Reader, Read Aloud browser extensions) — reads text aloud so you can listen instead of decode
• Speech-to-text (built into most devices) — dictate your thoughts instead of typing
• Grammar and spell checkers (Grammarly, Microsoft Editor) — catch the errors that dyslexia creates and ADHD means you miss when proofreading
• Colour overlays or tinted screens — can reduce visual stress for some dyslexic readers

3. Multi-Sensory Learning

The evidence for multi-sensory approaches is strong for both dyslexia and ADHD. Engaging multiple senses (seeing, hearing, touching, moving) keeps the ADHD brain stimulated while reinforcing learning through multiple channels for the dyslexic brain.

4. Shorter, More Frequent Sessions

Instead of one long study session that exhausts both your attention and your decoding stamina, try shorter sessions with breaks. Twenty minutes of focused work followed by a five-minute break is more effective than an hour of diminishing returns.

5. Access Support You Are Entitled To

In the UK:

• Students can access the Disabled Students Allowance (DSA) for both ADHD and dyslexia, funding assistive technology, study skills support, and mentoring
• Workers can request reasonable adjustments and Access to Work funding
• Everyone can request assessment through their GP or education provider

You Are Not Stupid

If you have ADHD and dyslexia, you have probably been made to feel stupid at various points in your life. By teachers who did not understand. By employers who questioned your competence. By yourself, comparing your output to people who do not have two neurodevelopmental conditions affecting every aspect of literacy and learning.

You are not stupid. Your brain processes information differently, and the world has not always been set up to accommodate that. But with the right strategies, the right tools, and the right support, you can absolutely thrive.
