What Causes Dyscalculia?

According to sources listed on both Understood.org and AboutDyscalculia.org, there is no universal consensus on the causes of dyscalculia. However there have been studies on what happens in the brains of dyscalculics while solving math problems. To understand this let´s first have a look at how children develop mathematic abilities in general.

NeuronalActivityBy the time they are just three months old, babies are able to differentiate between large and small quantities. When they get to preschool, children learn number words to enable them to describe these quantities. In elementary school, they learn Arabic numerals, which will not make any sense without those number words from the previous stage. Finally, children develop a mental conception of numbers – an internal number line – which automates such judgements as large vs. small, and estimations.

During this development, new skills are first processed in the anterior regions of the brain. These regions are responsible for logical thinking and for controlling attention and working memory. But as the brain masters these skills they are taken on by the posterior regions. This automates basic number tasks and frees up capacity in the anterior regions for processing more complex and difficult ones.

For children with dyscalculia, this process of skills becoming automatic happens much more slowly than for their peers. Instead these skills stay in the anterior regions of the brain, meaning that dyscalculic children have to concentrate fiercely to solve simple math problems. They rely on “counting out” the answer, a very slow process. As they advance through school the quantity and complexity of math problems they are expected to solve increases and along with it their anxiety. The more anxious a child becomes, the more overloaded will be his or her anterior brain regions, making it even more difficult to tackle numbers and solve problems. This can result in a life-long fear of math and can impact a dyscalculic student´s entire school and working career.

Dyscaculia is not nearly as well-known as dyslexia (chronic difficulty in reading) or dysgraphia (difficulty in writing). As a child with dyscalculia may be otherwise bright and creative, teachers and parents may not understand where the problems in math are coming from. This can lead to additional pressure on the child, who is already struggling with numbers and the feelings of inferiority these struggles cause.

Dyscalculia: even the term sounds unfamiliar. Many people with dyscalculia might not even know the condition exists. Instead they may just think they have difficulty with math, or that anything with numbers is a struggle for them. Even those familiar with the terms dyslexia and dysgraphia may never have heard of dyscalculia.

So what is dyscalculia exactly? Dyscalculia is a learning disability that affects around five percent of the population. People with dyscalculia may be intelligent and creative but struggle enormously with basic mathematical problems.

During childhood, specific regions of the brain develop and become specialised in the processing of numbers and mathematical thinking. In children with dyscalculia, the development of these specialised brain functions lags behind that of their peers.

When children experience these difficulties with numbers they can develop feelings of anxiety and inferiority whenever faced with math and arithmetic problems. These feelings can persist into adulthood, meaning that dyscalculia can have long-term psychological effects on those who have it.

Compared to dyslexia or even dyspraxia, dyscalculia is less widely-known and there are fewer resources out there for those dealing with dyscalculia. A dyslexic can do a quick search of “famous dyslexics” and come up with a list of celebrities and famous historical figures who are or were dyslexic. Dyscalculics will have much greater trouble locating others who can relate to their experience.

There are support communities and resources out there for those who have dyscalculia. Check back here Friday to learn about a few of them in our weekly roundup focusing this week on dyscalculia.

What Are The Symptoms Of Dyslexia?

What are the symptoms of dyslexia?

The earlier dyslexia is diagnosed, the sooner intervention can help children overcome their learning difficulties. This list from the Dybuster website shows that early symptoms may include difficulty with:

  • Learning the alphabet in the correct order
  • Associating sounds with their corresponding letters
  • Identifying or generating rhyming words or counting syllables in words
  • Segmenting words into individual sounds, or blending sounds to make words
  • Word retrieval or naming problems
  • Distinguishing between similar sounds in words; mixing up sounds in multi-syllable words (for example, “aminal” for animal, “bisghetti” for spaghetti)

Older children may exhibit:

  • Slow or inaccurate reading
  • Very poor spelling
  • Difficulty reading out loud, reading words in the wrong order, skipping words and sometimes saying a word similar to another word
  • Difficulty with associating individual words with their correct meanings
  • Difficulty with time keeping and concept of time when performing certain tasks
  • Difficulty with organizational skills
  • Failure to see (and occasionally to hear) similarities and difference in letters and words
