Can Someone Have Dyslexia and Dyscalculia at the Same Time?
People often ask, “Can someone have dyslexia and dyscalculia at the same time?” Although the two affect different skills, people can experience both. In this blog, we will look at what dyslexia and dyscalculia are, how they differ, and what it might look like when both are present.
We will also explain how these conditions are identified and why a qualified psychologist is needed to provide clarity through a proper assessment.
What Is Dyslexia?
Dyslexia is a specific learning disorder that primarily affects reading and spelling. It can make it harder to read words accurately and fluently, decode unfamiliar words, and spell correctly. Common areas affected by dyslexia include:
Reading accuracy and fluency
Spelling and written expression
Phonological processing
Reading comprehension
What Is Dyscalculia?
Dyscalculia is a specific learning disorder that affects a person’s ability to understand numbers and mathematical concepts. It can make it difficult to understand number sequences, estimate quantities, recall maths facts, or perform calculations. It can also affect the ability to apply mathematical reasoning to everyday situations, such as managing money.
Areas commonly affected by dyscalculia include:
Understanding number values and relationships
Performing calculations
Recognising patterns and sequences
Applying maths concepts to real-world tasks
Can Someone Have Dyslexia and Dyscalculia Together?
Yes, someone can have dyslexia and dyscalculia together. These are learning difficulties that can both present in the same person. Having one does not rule out the other, and each can affect different aspects of learning.
When dyslexia and dyscalculia occur together, difficulties may appear across several areas of learning and daily functioning. For example, a person might struggle with reading comprehension while also having difficulty following numerical instructions or managing step-by-step sequences. Some tasks involve both reading and mathematical skills, which can make it difficult to identify which difficulty is affecting a particular task.
How Do Dyslexia and Dyscalculia Arise?
Both dyslexia and dyscalculia are neurodevelopmental conditions, meaning they relate to differences in how the brain develops and processes certain types of information. They are not caused by a lack of effort, poor teaching, or low intelligence. Instead, they reflect differences that can affect how a person learns and processes language or numerical information.
How these difficulties appear can also change over time. A child may first struggle with classroom reading or basic number skills, while these challenges may become more noticeable as they get older and face more complex tasks.
These conditions are usually lifelong, but the right support and strategies may help reduce their impact on everyday learning and functioning.
What Might Dyslexia and Dyscalculia Look Like When They Occur Together?
Noticing possible signs is different from diagnosing a condition. A formal assessment by a qualified professional is needed to determine whether someone has dyslexia, dyscalculia, or both. That said, some general signs that may suggest a formal assessment include:
Ongoing difficulty with reading fluency alongside trouble with maths concepts
Struggling to follow multi-step instructions, whether written or numerical
Avoiding tasks involving reading or calculations
Difficulty with organisation, sequencing, or remembering information during language or number-based tasks
A sense that academic performance doesn’t match effort or general ability
These signs are not a checklist for self-assessment. Many of these signs overlap with other conditions, including ADHD, so a proper assessment is a reliable way to identify the underlying difficulties.
How Are Dyslexia and Dyscalculia Diagnosed?
A qualified psychologist can formally diagnose dyslexia and dyscalculia through a structured assessment process. This is not determined through online checklists or self-observation. A proper assessment typically involves:
A clinical interview to understand the person’s history and current challenges
Standardised cognitive testing to assess processing, memory, and reasoning
Academic testing to evaluate reading, writing, and maths skills
Analysis of results against established diagnostic criteria
This structured, evidence-based approach allows a psychologist to distinguish between dyslexia, dyscalculia, co-occurring conditions, or other explanations for academic difficulty altogether.
When Should Someone Get Assessed for Dyslexia and Dyscalculia?
Dyslexia and dyscalculia can be assessed during childhood or adulthood. For children, an assessment may be considered when ongoing difficulties with reading, writing, or maths are noticeable at school.
Adults can also seek an assessment if they have had these difficulties for years and want to better understand them or access appropriate support.
Educational Assessment At Adelaide Clinical Psychology
At Adelaide Clinical Psychology, our team of experienced psychologists are skilled in conducting comprehensive assessments for learning difficulties.
These assessments use evidence-based methods and online screening tests to assess areas such as reading, writing, maths, memory, and reasoning. Once the assessment is complete, a detailed report outlines the results and recommendations for support and accommodations.
Getting Clarity Through a Professional Assessment
So, to answer “can someone have dyslexia and dyscalculia at the same time?” We can say yes. Both conditions can occur in the same person, although they affect different areas of learning. A formal assessment can help determine whether dyslexia, dyscalculia, or both are present, providing a clearer understanding of the difficulties.
At Adelaide Clinical Psychology, our team takes a warm, supportive, and thorough approach to educational assessments. We understand that seeking answers about a learning difficulty can feel like a big step, and our kind and understanding psychologists are here to guide you through the process.
