ADHD and Dyslexia: Understanding the Connection

Ever wondered whether there’s a link between ADHD and dyslexia? Maybe you’re experiencing overlapping symptoms and aren’t sure how to tell them apart. To make things clearer, we’ll be walking you through the ins and outs of the two closely connected conditions, exploring their key differences, and letting you know what support is available if you think you might be affected by both.

Are Dyslexia and ADHD Neurologically Related?

It’s easy to see why many assume dyslexia and ADHD are related in some way. Both ADHD and dyslexia are neurodevelopmental conditions that share similar symptoms affecting attention, memory, and executive functioning. 

In research, ADHD and dyslexia have been shown to share a moderate genetic link, and we also know that people with ADHD are more likely to have dyslexia and vice versa

Despite this compelling evidence to suggest a tangible connection, there are some distinct differences between the two conditions. This means we can’t assume that if someone has ADHD, they’ll automatically have dyslexia or the other way around. 

Key Differences Between ADHD and Dyslexia

When we examine ADHD and dyslexia side-by-side, it becomes easier to spot the differences. 

First, let’s use their formal definitions to make a general distinction: 

Dyslexia: The British Dyslexia Association positions dyslexia as a condition primarily concerned with literacy skills. They describe it as “a set of processing difficulties that affect the acquisition of reading and spelling.” 

ADHD: Meanwhile, The National Institute for Health and Care Excellence present ADHD as a broader condition that is less focused on a particular area of skill acquisition. They define ADHD as a “heterogeneous disorder characterised by the core symptoms of hyperactivity, impulsivity and inattention, which are judged excessive for the person’s age or level of overall development.” 

As with all neurodevelopmental conditions, ADHD and dyslexia can extend beyond their main traits. However, if we think of dyslexia as related to literacy and ADHD as related to attention, it can help to remind us of the key differences.

It may also be useful to note that in British education, dyslexia is almost always agreed to be a learning difficulty, whereas with ADHD, it can depend on the institution. 

Next, let’s look at the symptoms that aren’t shared by both conditions.

Symptoms unique to ADHD:

  • Hyperactivity: The constant need to move, fidget, or feel restless.
  • Impulsivity: Acting without thinking, interrupting others, or making hasty decisions.
  • Hyperfocus: Some people with ADHD experience an intense fixation on activities or tasks they enjoy, sometimes to the exclusion of everything else.

Symptoms unique to Dyslexia:

  • Difficulty decoding words: Struggling to sound out or read words correctly.
  • Spelling issues: Persistent trouble with spelling, even for familiar words.
  • Mixing up similar-looking letters: Like confusing “b” and “d” or “p” and “q.”

As we can see, these symptoms are relatively distinct. This makes it slightly easier to recognise which challenges stem from ADHD and which from dyslexia – even when they appear together.

Shared Characteristics of Individuals with ADHD and Dyslexia

Now that we can recognise the differences between ADHD and dyslexia, let’s take a look at where the two conditions overlap:

  • Difficulties with concentration: Both ADHD and dyslexia can make it hard to focus on tasks, especially those requiring sustained mental effort.
  • Short attention span: In both conditions, individuals may struggle to stay engaged with activities for extended periods.
  • Poor memory: Challenges with working memory may also affect people with both conditions. This can make it difficult for people to retain and process information.
  • Organisational difficulties: Both ADHD and dyslexia can lead to problems with time management and staying organised.
  • Reading and writing challenges: Both conditions can affect academic literacy but in different ways. ADHD can lead to jumbled thoughts, making it harder to maintain focus during reading and writing, while dyslexia primarily affects word processing and language acquisition, making it tricky to read smoothly, spell correctly, and write clearly.
  • Genetically acquired: Both ADHD and dyslexia have a strong genetic component. Studies suggest that they tend to run in families, indicating a hereditary influence. 

As you can see, some of the above symptoms could appear the same to an outsider but stem from different causes. This can lead to behaviours being misinterpreted or the wrong kinds of support being offered. A thorough assessment by a specialist is always the best way to ensure that conditions are clearly defined and the right treatment or support is provided.

Can You Be Diagnosed with Both Dyslexia and ADHD?

Yes. As we mentioned earlier, research has shown that having dyslexia or ADHD can increase your chances of having coexisting conditions. Since life can become very difficult for people with both ADHD and dyslexia, especially in work or educational settings, a prompt diagnosis is vital. This ensures people get the support they need so that their conditions don’t disadvantage them or start to affect their mental health.

Support Strategies for Individuals with Coexisting ADHD and Dyslexia

If you’ve recently received a diagnosis of dyslexia and ADHD, there are a number of support options available which can make life easier to manage. 

Assistive Technology: Assistive technology tools like dictation software, text-to-speech programs, and note-taking apps can make tasks like reading and writing easier for those with ADHD and dyslexia. Dyslexia-friendly fonts and organisational apps may also be beneficial.

Educational Support: In education, schools and colleges often provide Individual Education Plans (IEPs) or access to Special Educational Needs Coordinators (SENCOs) who can tailor learning approaches so that those with combined conditions have what they need to succeed academically and overcome learning challenges. 

Workplace Accommodations: Employers can offer workplace accommodations such as flexible working hours, quiet workspaces, extra time for tasks, or assistive tools. This is because both conditions can be classed as disabilities under the Equality Act 2021, provided the impacts of a person’s symptoms meet certain criteria.

Therapies and Interventions: Therapies and interventions can help those with both conditions to manage emotions and advance in areas they struggle with. For example, Cognitive-behavioural therapy (CBT) or coaching can help to manage ADHD symptoms and their effects, while structured literacy programmes may help with dyslexia.

Support Groups and Charities: Organisations like the British Dyslexia Association and ADHD UK offer workshops and other resources. These can help with everything from focus and time management to financial support and advice.
