When should this dyscalculia test be used?

When should this dyscalculia test be used?

This assessment battery makes it possible to reliably detect the risk of presenting dyscalculia in children 7 years and older and adults.

We recommend using this test for anyone who you may suspect has dyscalculia. The early detection of this learning disorder can help minimize developmental difficulties and start an appropriate intervention program suitable for each profile.

This assessment battery also makes it possible for adults to understand their risk index for having dyscalculia. Many adults have lived their entire lives with dyscalculia and were never aware of the dysfunction. And, while they may have a normal, or even above average IQ, they may have been considered poor students. Without the early detection and proper management of this learning disorder, adults with dyscalculia may have problems at work or in social situations.

Below are some of the most representative symptoms of dyscalculia:

General symptoms

Difficulties with mathematical calculations

People with dyscalculia have trouble processing mathematical language, which makes it difficult to do mathematical processes like adding, subtracting, multiplying, and dividing.

Difficulties recognizing mathematical symbols

People with dyscalculia may confuse symbols like “+” or “-“, which may create problems when using and applying them to mathematical operations.

Problems aligning mathematical operations

It is common to have trouble changing a vertically written math problem horizontally and vice versa. With operations like multiplication or division, someone with dyscalculia may have trouble aligning the right numbers and symbols in order to get the correct answer.

Difficulties understand spoken word problems

May present difficulties remembering the information given in the word problem, which can make it very difficult, or even impossible, to correctly write and carry-out the correct mathematical operation. It is also common to have trouble differentiating relevant and irrelevant information.

General symptoms

Aside from the purely mathematical problems, people living with dyscalculia may also have trouble telling time, they may get lost often, and they may have poor orientation.

Description of the diagnostic criteria questionnaire

Description of the diagnostic criteria questionnaire

Dyscalculia is characterized by a series of clinical signs and symptoms. These indicators can help you understand the risk of someone having this learning disorder. This is why the first part of the Cognitive Assessment for Dyscalculia Patients (CAB-DC) is a questionnaire made of questions that have been adapted to the diagnostic criteria and symptoms of dyscalculia for each age range.

The questions presented here are similar to those that can be found in a diagnostic manual, questionnaire, or evaluation scales. However, they have been simplified to be easily understood by almost any user.

Diagnostic criteria for children 7-18 years-old

Made up of a series of simple questions that should be answered by a parent or the professional in charge of the assessment. The questionnaire will cover the following domains: Mathematical language (comprehension of the mathematical symptoms, their meaning, and representation), Mathematical reasoning (numeric thinking, problem solving, logic, etc.), Social relationships (caused by frustration and frustration that may these math problems may have caused), Learning and development (dyscalculia is related to different familiar and developmental factors).

Diagnostic criteria for adults

A series of simple questions that can be completed by the professional in charge of the evaluation or by the person taking the test. The questionnaire will cover the following domains: Mathematical language (comprehension of mathematical symptoms, their meaning, and representation), Mathematical reasoning (numeric thinking, problem solving, logic, etc.), Academic history (due to the relation between dyscalculia and academic failure), Professional and social areas (difficulties with the relationship of calculations and daily life).

Dyscalculia and The Brain

Dyscalculia and The Brain

Dyscalculia makes it difficult to understand and carry-out math operations. Neuroimaging studies have consistently shown the close relationship between dyscalculia and certain brain areas. Some of the most affect brain areas in dyscalculia are:

1 Intraparietal ridge

Recent studies have shown that the intraparietal ridge, especially in the right hemisphere, is one of the brain structures that shows anomalies in people with dyscalculia. This right intraparietal ridge is crucial for the correct processing of numeric information.

2 Frontal lobe

The frontal lobe, especially the prefrontal dorsolateral portion, is closely related to executive functions, like planning or working memory, which is both necessary to carry out calculations and solve mathematical problems. Dyscalculia may also cause an alteration in the cognitive abilities related to this area of the brain.

3 Superior Parietal Lobe

The right parietal lobe that interprets spatial information, while the left parietal lobe understand numbers, the manipulation of different objects, and writing.

4 Left Angular Gyrus

In charge of the verbal use of numbers.
