25 Oct What’s the best treatment for children with dyscalculia?
Considering that academic achievement is highly valued in our society, we often compare the performance of our schoolchildren. On a personal level, because parents often invest a great deal of time, resources, and emotional energy to ensure their children’s academic success. It can be extremely upsetting when a child with no obvious intellectual deficits does not achieve as expected. That is the reason to ensue for the early academic disability evaluation. This ensures that these children do not suffer the scars of many painful school-related episodes of failure.
Dyscalculia, also known as “math dyslexia,” includes learning disorders related to mathematics, such as difficulty with numbers, concepts, and reasoning. The term “dyscalculia” (from the Greek dys and Latin calculia) was used by Cohn (1968) to refer to a “failure to recognize numbers or manipulate them in an advanced culture,” and later by Kosc (1974), a Bratislavian, as “a disorder of the special abilities for mathematics without a simultaneous defect in general mental abilities.” People with dyscalculia may struggle to count money, read clocks and tell time, perform mental math calculations, identify number patterns, and apply mathematical formulae.
Causes of Dyscalculia
Researchers do not yet have a definitive understanding of the causes of developmental dyscalculia. However, similar to other learning disabilities, it is believed that a combination of genetics and environmental factors plays a role. Academic disability evaluation takes these factors into consideration. Experts continue to differentiate between math problems stemming from brain processing deficits. They also consider difficulties related to factors such as poor instruction, poverty, or coexisting conditions.
- It is also possible, though rare, for someone to acquire dyscalculia as the result of a brain injury or stroke. This form of the disorder typically stems from damage to the parietal lobe of the brain. It may be referred to as “acalculia.” A sign of dementia, may also be the sudden problems with math.
like other learning disabilities, is thought to be strongly influenced by genetics. Individuals with dyscalculia are significantly more likely than the general population to have family members with dyscalculia, research finds.
is sometimes called “math anxiety,” though the nickname isn’t quite accurate. Someone can feel persistently anxious at the thought of doing math but not have dyscalculia; on the other hand, for some individuals with diagnosable dyscalculia, anxiety may worsen the difficulties they experience. And regardless of dyscalculia, math anxiety can be serious and lead to long-term math avoidance; some research has found that for some people who struggle with math anxiety, the anticipation of having to do math activates the same centers in the brain that register visceral threats and physical pain.
Poor math instruction-
cannot cause brain-based developmental disorders such as dyscalculia. However, poor math instruction can lead some children to struggle with common math concepts or do worse in math than they otherwise would. Determining whether a child’s difficulties with math are due to dyscalculia or to another cause, including poor instruction, is a key component of an academic disability evaluation.
However, during academic disability evaluation it’s important to note that dyscalculia, along with other learning disabilities, should not be mistaken for learning problems that arise due to other factors such as:
- Visual, hearing, verbal, or motor handicaps
- Intellectual disability
- Emotional disturbances
- Economic, cultural, or environmental disadvantages
Signs and the behavior profile of children with Dyscalculia
The pattern of problems with arithmetic seen in such children will vary as a function of age. Children with arithmetic difficulties initially experience problems learning to count. Once the formal teaching of arithmetic begins, these children show delays in mastering addition and subtraction, and they may tend to rely on the “count-on” strategy when solving simple addition problems for longer than typically developing children (Geary, 2004). With more complex addition problems, children with mathematics disorder tend to guess more often than their peers. Additionally, their guesses are typically less accurate (Geary et al., 2004). Although they use the same strategies as age-matched controls, they differ in the speed and skill of strategy execution. They also have difficulty retrieving number facts from memory, struggle with monitoring their counting, and are poor at detecting computational errors (Geary, 2004).
One common sign that persists across the lifespan is the sole reliance on finger counting. Typically, children start to switch from finger counting to more efficient calculation strategies, such as retrieval of math facts from memory, by about age 8 or 9.
Other common features include:
- a poor sense of numbers in terms of their magnitude and relationship
- inaccurate counting and calculation
- failure to attend to key mathematical symbols (e.g., symbols for addition, subtraction, multiplication, division)
- difficulty with identifying the previous or next item in a sequence (e.g., difficulty identifying the name of previous or next day, month, or number, despite being able to rote list those items)
difficulty understanding the concept and use of “zero” or decimal points;
and “gets lost” in the middle of multidigit calculation and may switch procedures or apply them incorrectly (e.g., in the problem 57 – 38, may start to subtract 7 from 8 instead of 8 from 7, then either subtracts 3 from 5 without considering the trading procedure, or may switch to adding 5 and 3)
Many struggle with understanding the “language” of mathematics,
especially in word problems, that are emphasized in current curricula across all grade levels
Word problems consist of two layers:
A narrative about some event or sequence of events in the real world, and a latent web of mathematical relations typically expressed in words, and related by a question involving concepts of quantity such as “more,” “more than,” “less than,” “altogether”
- Moreover, older children, adolescents, and adults manifest difficulty understanding and using money, telling the time, using calculators, and remembering numerical PIN codes
is another common feature that persists across the lifespan and it is to be considered during academic disability evaluation. Often described as “a feeling of tension, apprehension, or fear that interferes with math performance,” it may manifest as sweaty palms, a racing pulse, breaking out in a cold sweat, or choking feeling in the back of the throat, when required to perform mathematics in everyday life (e.g., answer math questions in class; complete math homework, counting out money to buy something, splitting a restaurant bill or calculating the tip, entering specific numbers for cash withdrawal or deposit at an ATM machine)
Criteria for Diagnosis
There are no biomarkers to date for SLD. Thus, SLD is a clinical diagnosis, which is best made by an experienced clinician, based on a comprehensive academic disability evaluation with careful clinical synthesis of information from multiple sources, including:
- developmental, medical, educational, and family history
- school reports; teacher observations, including response to classroom instruction and other intervention provided at school
- direct standardized psychometric assessment of the individual’s academic skills— including reading, spelling, written expression, and arithmetic (number sense, counting, algorithmic computation)
Treatment focuses almost exclusively on academic intervention and rarely includes mental health services. However, students with learning disabilities experience higher levels of inattention (including ADHD), anxiety, and depression. This is in contrast to their peers without these disabilities. Moreover, treatment of SLD is typically carried out in education settings or specialized psychology clinics. As a result, it is not the primary responsibility of psychiatrists or primary care providers.
The primary role of medical health care providers is that of coordinator. As a first step, this role includes the provision of psychoeducation about the disorder and its longer-term implications.
A second critical step is to establish a monitoring plan with the patient and family. This plan allows for early detection and management of commonly associated mental health problems, such as ADHD, anxiety, and depression. As well as to ascertain whether recommended accommodations have been put in place along with intensive, individualized, explicit instruction.
