What is Dyscalculia?
Dyscalculia is a learning disability that affects an individual’s ability to understand and work with numbers. Also referred to as acalculia, arithmetic disability, or number agnosia, dyscalculia manifests in various forms, including developmental, secondary, and acquired.
Developmental Dyscalculia: Developmental dyscalculia arises from early childhood, leading to challenges in comprehending numerical concepts. Those affected may struggle with number order, counting objects, and grasping the significance of numbers.
Secondary Dyscalculia: Secondary dyscalculia occurs post-literacy acquisition due to factors such as head injuries, strokes, or neurodegenerative diseases. Individuals who previously demonstrated numerical proficiency may suddenly face difficulties.
Acquired Dyscalculia: Acquired dyscalculia involves the loss of numerical comprehension in individuals previously proficient with numbers. This condition can result from trauma, brain tumours, substance abuse, or dementia associated with Alzheimer’s disease.
Causes of Dyscalculia: Research indicates that dyscalculics struggle with the abstract nature of numbers. Unlike neurotypical individuals who intuitively grasp numerical relationships, dyscalculics perceive numbers differently, often failing to recognize fundamental connections.

Symptoms of Dyscalculia
Recognising the symptoms of dyscalculia is crucial for early intervention and support. Here are some common signs:
- Difficulty with basic arithmetic: Individuals with dyscalculia often struggle with simple addition, subtraction, multiplication, and division, even well into adulthood.
- Poor number sense: They may have trouble understanding the relative size of numbers or estimating quantities.
- Challenges with time and money: Managing time, reading analog clocks, or handling money transactions can be particularly difficult.
- Spatial awareness issues: Problems may arise when judging distances or navigating directions.
- Difficulty remembering mathematical facts: Memorizing multiplication tables or mathematical formulas can be extremely challenging.
- Trouble with mental math: Performing calculations in their head may be nearly impossible for some individuals with dyscalculia.
- Sequencing problems: They might struggle with putting numbers or events in the correct order.
- Anxiety around math: Many people with dyscalculia develop math anxiety, leading to avoidance of mathematical tasks.
- Difficulty recognizing patterns: Identifying and continuing numerical or geometric patterns can be challenging.
- Trouble with abstract concepts: Understanding abstract mathematical ideas, like algebra, can be particularly difficult.
Example of The Impact of Symptoms of Dyscalculia:
Sarah, a 12-year-old student, exhibits several symptoms of dyscalculia. Despite being articulate and creative in language arts, she struggles significantly with math. When asked to solve a simple addition problem like 8 + 5, Sarah often counts on her fingers or uses tally marks, a strategy typically seen in much younger children. She frequently reverses numbers when writing them down, writing 51 instead of 15.
During a recent math test, Sarah became visibly anxious and took much longer than her classmates to complete simple calculations. When working on word problems, she has difficulty extracting the relevant numerical information and deciding which operation to use. Sarah also struggles with telling time on an analog clock and often arrives late to classes because she can’t gauge how long activities will take.
These symptoms have led Sarah’s teachers and parents to consider having her evaluated for dyscalculia, as early identification and targeted support could significantly improve her mathematical skills and overall academic experience.

Identifying dyscalculia often involves recognising its symptoms through behavioural cues. Individuals with dyscalculia may exhibit difficulties in counting, comprehending numbers as wholes rather than individual digits, grasping mathematical concepts, understanding time, and spatial relationships, and interpreting graphs or charts.
Taking a Dyscalculia Test
Dyscalculia tests are crucial for accurate diagnosis and intervention. These assessments typically involve mental math problems or tasks to evaluate mathematical understanding. Anyone experiencing challenges with numbers should consider taking a dyscalculia test, including students, adults managing finances, or seniors planning retirement.
Test Preparation and Duration
Preparing for a dyscalculia test involves familiarity with mathematical concepts. While there’s no specific preparation, completing math classes and seeking assistance from friends or relatives can aid in test readiness. Test durations vary, typically lasting from 15 minutes to an hour, with the flexibility for additional time if needed.
Test Administration
Tests may be administered online, in educational settings, or through medical professionals. Online tests may incur a fee, while in-person assessments are often complimentary.
Free Online Dyscalculia Test: This test will give you a good indication if you have Dyscalculia. It is free and simple to complete. Please note there is a difference between having dyscalculia and just not understanding and being able to apply mathematical concepts.
Frequently Asked Questions
1. Can dyscalculia be self-diagnosed?
No, it requires professional diagnosis through specialized tests. Self-diagnosis is insufficient for accurate assessment.
2. Is dyscalculia linked to ADHD?
The co-occurrence of dyscalculia and ADHD is a notable phenomenon that warrants attention and understanding. Research indicates that while these two conditions are distinct, they often manifest together in individuals. In fact, it has been observed that up to 50% of children diagnosed with ADHD may also exhibit symptoms. This correlation can be attributed to shared attentional and cognitive factors that are present in both conditions. Understanding this overlap is crucial for developing effective strategies to support individuals who experience the challenges posed by both conditions.
3. Is dyscalculia a reading disorder?
Dyscalculia primarily affects mathematical skills rather than reading abilities. However, individuals with dyscalculia may struggle with word problems and mathematical language.
4. Does dyscalculia run in families?
Research suggests a familial predisposition to this, indicating a genetic component in its aetiology.
Conclusively, dyscalculia poses significant challenges in numerical comprehension but can be effectively managed with appropriate diagnosis and intervention strategies.
