Attention-deficit hyperactivity disorder (ADHD) and dyslexia are neurodevelopmental conditions that, while distinct, frequently co-occur and share some overlapping symptoms, leading to confusion in diagnosis. ADHD is characterized by persistent patterns of inattention, hyperactivity, and impulsivity, whereas dyslexia primarily affects reading and language-based processing skills. Understanding the nuances of each condition, especially when they present together, is crucial for accurate diagnosis and effective intervention.
It’s increasingly recognized that ADHD and dyslexia are not mutually exclusive. In fact, research indicates a significant comorbidity between the two. Children with ADHD are more prone to learning disabilities in general, and dyslexia is a common learning disability they may experience. Statistics vary, but studies suggest that 25% to 40% of individuals with ADHD also have dyslexia, and a similar percentage of those with dyslexia also meet the criteria for ADHD. This co-occurrence highlights the complex interplay between attention, executive functions, and reading abilities.
This article aims to clarify the connection between ADHD and dyslexia, explore how they are differentiated, discuss the diagnostic process for each, and outline effective strategies for managing both conditions when they co-exist.
The Interplay Between ADHD and Dyslexia
Historically, ADHD and dyslexia were often considered separate and unrelated conditions. However, contemporary research has revealed a significant overlap, particularly in the realm of executive functions. Executive functions are a set of cognitive skills that control and regulate other cognitive abilities and behaviors. They include working memory, flexible thinking, and inhibitory control. Impairments in executive functions are central to ADHD, and these same impairments can also contribute to the challenges faced by individuals with dyslexia.
While distinct disorders, the presence of both ADHD and dyslexia in an individual often indicates broader executive function deficits alongside specific impairments in reading-related skills such as phonological processing and rapid symbol recognition. This means someone with both conditions might struggle not only with reading fluency and decoding words (hallmarks of dyslexia) but also with maintaining focus, organizing tasks, and managing impulsivity (characteristics of ADHD).

Distinguishing between ADHD and dyslexia can be challenging because both are neurodevelopmental conditions that can manifest in similar ways, especially in academic settings. Since ADHD affects attention and dyslexia impacts reading, some overlapping behaviors can mask the underlying cause of the difficulty. Let’s examine some key areas where similarities and differences emerge:
Distractibility: A Shared Symptom with Different Roots
Both children with ADHD and dyslexia may appear distracted in the classroom or during learning activities. However, the reason for this apparent distraction differs significantly.
A child with ADHD may be inattentive due to difficulties regulating their attention. Their minds might wander easily, they may be overly sensitive to external stimuli, or they might struggle to sustain focus on tasks they find less engaging. This distractibility is a core symptom of ADHD and is not specific to reading tasks.
In contrast, a child with dyslexia might appear distracted during reading tasks because reading is exceptionally effortful and demanding for them. Decoding words, a process that is automatic for typical readers, requires significant cognitive resources for someone with dyslexia. This intense effort can lead to mental fatigue and a seeming lack of focus, as the child’s energy becomes depleted. The “distraction” in this case is often a coping mechanism to avoid the frustrating and laborious process of reading.
Fluency in Reading: Varied Obstacles to Smooth Reading
Reading fluency encompasses accuracy, speed, and prosody (expression when reading aloud). Fluent reading is essential for comprehension; if a child struggles to read fluently, their ability to understand what they read is compromised.
A child with ADHD may exhibit reading fluency issues due to impulsivity and inattention. They might rush through text, skip words or lines, or lose their place because their mind races ahead. This impulsivity can lead to careless reading errors and a lack of reading pace, hindering comprehension. Their difficulty lies in maintaining focus and reading systematically.
On the other hand, a child with dyslexia may struggle with fluency due to difficulties in phonological processing – the ability to recognize and manipulate the sounds of language. They may spend considerable time sounding out words, misread words despite recognizing individual letters, or read slowly and laboriously. Their fluency is impaired by the core dyslexic challenge of decoding and word recognition.
Regardless of the underlying cause, both ADHD and dyslexia can result in reduced reading fluency, impacting comprehension and making reading an unenjoyable and frustrating activity.
Writing Challenges: Organizational vs. Decoding Difficulties
Writing and handwriting can also present challenges for individuals with both ADHD and dyslexia, although the nature of these challenges differs.
Someone with ADHD might struggle with the organizational aspects of writing. They may have difficulty planning and structuring their thoughts, leading to disorganized essays or written work. They might also struggle with proofreading due to inattention to detail, resulting in careless errors in their writing.
A child with dyslexia faces different writing obstacles. Their difficulties stem from the same language-based processing issues that affect reading. They may struggle with spelling, grammar, and organizing ideas on paper. Handwriting can also be affected, sometimes due to associated fine motor difficulties or the cognitive load of trying to spell and form letters simultaneously. Proofreading is challenging because they may not visually recognize their own spelling errors.
A key distinction is that dyslexia-related difficulties are primarily evident in reading and writing tasks, while ADHD symptoms are more pervasive, impacting behavior and attention across various settings and activities, not just those related to literacy.

Complications Arising from Co-occurring ADHD and Dyslexia
When ADHD and dyslexia coexist, the challenges associated with each condition can be amplified. Dyslexia, in isolation, already presents difficulties in reading, spelling, and word recognition, which can hinder vocabulary development, reading comprehension, and the acquisition of general knowledge compared to peers without dyslexia. It’s important to reiterate that dyslexia is not indicative of lower intelligence; individuals with dyslexia typically have average to above-average cognitive abilities.
However, the struggles associated with dyslexia can unfortunately lead to diminished self-esteem and academic self-confidence. Children with dyslexia may internalize their reading difficulties, perceiving themselves as less intelligent or capable than their peers.
The presence of ADHD alongside dyslexia can exacerbate these emotional and academic challenges. ADHD-related inattention further complicates the already demanding task of reading for someone with dyslexia. Individuals with ADHD also often experience lower self-esteem and confidence, frequently stemming from academic or work-related struggles caused by inattention, impulsivity, and hyperactivity. The combined impact of ADHD and dyslexia can create a cycle of frustration, academic underachievement, and diminished self-worth.
The Diagnostic Process for ADHD and Dyslexia
Diagnosing ADHD and dyslexia involves distinct processes and is often conducted by different professionals.
ADHD diagnosis is typically made by medical professionals such as psychiatrists, psychologists, neurologists, or even primary care physicians. The diagnosis is based on criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR), which involves assessing the presence and severity of inattentive, hyperactive, and impulsive symptoms. This assessment often includes clinical interviews, behavioral rating scales completed by parents and teachers, and direct observation of the individual.
Dyslexia diagnosis, on the other hand, often originates within educational settings. Educators are usually the first to identify reading difficulties that might suggest dyslexia. They may then refer the individual to specialists for formal assessment. Dyslexia is typically diagnosed by clinical psychologists, school psychologists, educational psychologists, or neuropsychologists. The evaluation process for dyslexia involves comprehensive testing of reading skills (decoding, fluency, comprehension), phonological processing, spelling, and sometimes writing. It’s crucial to rule out other potential causes for reading difficulties, such as vision or hearing problems, or lack of adequate reading instruction.
It’s important to note that because dyslexia is considered an educational condition rather than a medical one, evaluations for dyslexia may not always be covered by medical insurance, depending on the provider and specific plan.
The severity of both ADHD and dyslexia exists on a spectrum, ranging from mild to severe. This means that the presentation of symptoms will vary significantly from person to person. No two individuals with ADHD or dyslexia will exhibit identical symptom profiles.
Treatment and Intervention Strategies for ADHD and Dyslexia
Treatment approaches for ADHD and dyslexia are also distinct, although some overlapping strategies can be beneficial when both conditions are present.
ADHD management often involves a combination of medication and behavioral therapies. Medications, primarily stimulants like Adderall, Concerta, Focalin, and Ritalin, are frequently prescribed to help manage core ADHD symptoms such as inattention, hyperactivity, and impulsivity. Non-stimulant medications like Strattera and Wellbutrin XL are also available as alternatives.
Behavioral strategies for ADHD focus on improving focus, reducing distractions, and establishing routines and organizational skills. These strategies can include implementing structured routines, using visual aids like charts and planners, and employing timers and alarms to aid in task management and time awareness.
Dyslexia intervention primarily centers on specialized educational programs designed to improve reading and language skills. Many effective dyslexia programs are based on or incorporate elements of the Orton-Gillingham approach, a research-backed, multisensory method widely recognized as effective for dyslexia. These programs emphasize phonemic awareness (understanding sounds in words), phonics (letter-sound relationships), fluency building, vocabulary development, and explicit instruction in spelling rules.
It’s crucial to seek out dyslexia reading programs that are evidence-based and comprehensive, addressing key components of reading development. Schools may offer specialized teachers or programs for students with dyslexia; however, if school-based support is insufficient, private tutoring with a specialist trained in dyslexia intervention can be highly beneficial.
Academic accommodations are essential for students with both ADHD and dyslexia to enable them to reach their full academic potential. These accommodations might include extended time on tests and assignments, preferential seating, assistive technology, and modified assignments.

Coping Strategies for Individuals with ADHD and Dyslexia
One of the most significant challenges for children (and adults) with ADHD and dyslexia is maintaining positive self-esteem and self-confidence. Academic struggles and difficulties with tasks that peers find easy can erode self-worth. Here are some coping strategies to foster resilience and self-acceptance:
Identification and Understanding
Simply having a name for their challenges – ADHD and dyslexia – can be incredibly validating for children. Understanding that they have recognized conditions helps them make sense of their experiences and avoids self-blame. It reframes perceived “deficiencies” as symptoms of a condition, replacing negative self-labels like “stupid” or “dumb” with a more accurate and compassionate understanding.
Focus on Effort and Progress
Provide positive reinforcement for effort rather than solely focusing on outcomes or grades. Children with ADHD and dyslexia often have to work significantly harder than their neurotypical peers to achieve the same results. Acknowledging and praising their effort, regardless of the final grade, validates their hard work and boosts their self-esteem.
Encourage Extracurricular Activities
Support and encourage participation in activities outside of academics that align with a child’s interests. Excelling in a non-academic area, whether it’s sports, martial arts, music, art, or any other hobby, builds confidence and a sense of competence. This positive experience can spill over into other areas of life, including academics, fostering a more positive self-perception overall.
Recap: Empowering Children with ADHD and Dyslexia
Helping children understand their ADHD and dyslexia, emphasizing effort over achievement, and promoting engagement in extracurricular activities are crucial strategies for fostering coping skills and resilience in the face of these challenges.
Summary
ADHD and dyslexia are neurodevelopmental conditions that frequently co-occur, leading to complex challenges in learning and self-perception. While distinct, they share overlapping symptoms and can exacerbate each other’s difficulties. Accurate diagnosis by qualified professionals is essential for accessing appropriate interventions. Management strategies include medication and behavioral therapy for ADHD, and specialized educational programs for dyslexia. Crucially, fostering self-esteem, recognizing effort, and providing supportive environments are vital for individuals with ADHD and dyslexia to thrive.
A Word From Verywell
When discussing dyslexia, the phrase “early intervention is key” is often emphasized, and indeed, early identification of any condition is generally beneficial. However, if you suspect your child has dyslexia later in their childhood, or even as a teenager or adult, do not feel discouraged or guilty. It is never too late to seek testing and appropriate support.
In cases where a child has both ADHD and dyslexia, the symptoms of ADHD can sometimes mask the telltale signs of dyslexia, delaying diagnosis. Furthermore, children are often adept at developing compensatory strategies to hide their difficulties, making problem detection even more challenging.
If you are an adult reading this and suspect you might have dyslexia, it is still worthwhile to pursue an evaluation. Even if you are no longer in formal education, understanding the root of your challenges can significantly improve your self-confidence, self-esteem, and career trajectory. Seeking diagnosis and understanding is a positive step at any age.
