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.
