Description

Cognitive assessment battery to evaluate and detect dyslexia

  • Evaluate the risk index of the presence of dyslexia
  • For children over 7, teens, and adults
  • The test lasts about 30-40 minutes

The Cognitive Assessment Battery for Dyslexia (CAB-DX) is a leading professional tool made up of a battery of clinical and validated tasks aimed at quickly detecting and assessing the presence of symptoms, traits, or poor functioning of the cognitive processes affected by dyslexia.

This innovative online dyslexia test is a scientific resource that makes it possible to take a complete cognitive screening, see cognitive strengths and weaknesses, and evaluate the risk index of the presence of dyslexia with excellent reliability. This test is perfect for children 7 years and older, teens, and adults. Any user, either professional or personal, can easily use this neuropsychological assessment battery.

The report from this assessment battery will automatically be available for download after completing the evaluation, which usually takes about 30-40 minutes.

Dyslexia is, in general, underdiagnosed. However, this learning disorder creates significant and persistent difficulties that affect linguistic abilities associated with reading and writing. A clinical history and the evaluation of different areas, especially neuropsychology, are still the most effective tools to diagnose dyslexia. This complete dyslexia test should be used to complement a professional diagnosis, and never as a substitute for a clinical consultation.

Digitalized protocol for the dyslexia assessment (CAB-DX)

This complete cognitive evaluation to detect dyslexia is made of a questionnaire and a complete battery of neuropsychological tests. It takes about 30-40 minutes to complete.

The person taking the test will complete the initial questionnaire designed to evaluate the signs and symptoms of dyslexia appropriate for the user's age. Following the questionniare, the user will complete the tasks presented as simple online games.

Diagnostic Criteria Questionnaire

A series of questions designed to detect the main diagnostic criteria and symptoms of dyslexia will be presented to the user, with questions adapting to the user's age.

Neuropsychological factors and cognitive profile

It continues with a battery of tasks designed for evaluating the main neuropsychological factors identified in the scientific literature surrounding this learning disorder, paying close attention to executive functions. The battery uses clinical scaled and validated tests adapted to each user's age.

Complete results report

After completing the dyslexia test, you will receive a detailed report, where you will see the user's risk index for dyslexia (low-medium-high), the warning signs and symptoms, cognitive profile, analysis of results, and recommendations. These results offer valuable information to identify support strategies or to bring to a specialist who can make a more precise diagnosis.

Psychometric Results

The Cognitive Assessment Battery for Dyslexia uses patented algorithms and artificial intelligence (AI), which makes it possible to analyze thousands of variable and notify users of a risk of dyslexia with very satisfactory psychometric results.

The neuropsychological cognitive report has a high reliability, consistency, and stability. The test has been validated by repeated tests and measurement processes. Transversal research designs have been followed, like the Alpha Cronbach coefficient, reaching scores of about .9. The Test-Retest tests have received scores of almost 1, which shows the high reliability and precision that this battery offers.

ANALYSIS AND RECOMMENDATIONS

This powerful software makes it possible to analyze thousands of variables and offer specific recommendations tailored to each user.

When should you use this dyslexia test?

With this assessment battery, it's possible to reliably detect a user's risk index of dyslexia in children 7 years and older.

If you think that someone may have dyslexia, we recommend using this assessment as soon as possible in order to start the appropriate cognitive intervention. An early detection makes it possible to minimize the developmental difficulties associated with dyslexia and get started training and improving the areas affected by it.

This assessment battery for dyslexia also makes it possible for adults to understand their risk index for dyslexia. Many adults have suffered with dyslexia and reading difficulties their whole life because they were never diagnosed with this learning disorder. While these people may have an average, or even an above average, IQ, they may have had significant trouble as students. Without an early detection and the proper tools, dyslexia may affect a person's professional, social lives.

Below are some of the most characteristic symptoms of dyslexia:

Subtypes of Dyslexia
Most representative symptoms
Description
Hyperactive-Impulsive Predominance
Writing difficulties
Reading difficulties
Difficulty planning tasks
Problems with motor coordination and spatial orientation.
Difficulties in professional and social areas

Writing difficulties

People with dyslexia often have trouble correctly processing the symbols used in writing. They have trouble spelling words and expressing ideas when writing. They may be able to understand something or someone perfectly when presented orally but have trouble taking notes in class. Children and adults with dyslexia may have irregular or illegible handwriting, and trouble when writing similar words, like "dad" and "bad".

Reading difficulties

People with dyslexia often have trouble decoding information, which is why reading is so difficult. They often read slowly and have a hard time understanding the meaning of a written text, and have trouble memorizing or storing information they've read. People with dyslexia are not usually very interested in reading due to the extra difficulty it poses.

Difficulty planning tasks

Difficulties with the development of the executive functions is one of the most recurring characteristics of dyslexia. This means that any task that requires planning may be a challenge for someone with this learning disorder. Executive functions are a set of complex cognitive skills that make it possible to plan any task and divide it into steps (analyze the task, understand what you need to do, organize, determine how long it will take to carry-out, structure the work, and assess actions and adjust them as necessary).

Problems with motor coordination and spatial orientation.

Some people with dyslexia have trouble with motor coordination and have trouble distinguishing between their right and left, up and down, in front and behind, etc. This problem may cause a certain clumsiness in daily life and may lose things more often. For example, people with dyslexia may have trouble when playing sports or riding a bike.

Difficulties in professional and social areas

The reading and writing difficulties caused by dyslexia start in childhood and become more and more apparent as academic challenges become greater. There is a close relationship between academic difficulty and dyslexia, as someone with dyslexia may be labeled a "lazy" student due to the difficulties they face. Adults with dyslexia may continue to have trouble in their professional field.

Description of the diagnostic criteria questionnaire

Dyslexia is characterized by a series of clinical signs and symptoms. These indicators can help you understand the possible presence of dyslexia, which is why the dyslexia assessment adjusts the questionnaire to adapt to each user's specific diagnostic criteria and symptoms for their age.

The questions presented here are similar to those that you may find in a diagnostic manual, questionnaire, or clinical evaluation scales. However, they have been simplified to be understood and answered by almost anyone.

Diagnostic criteria for children 7-12 years-old

It is made up of a series of simple questions that can be completed by the user him or herself, or by the professional in charge of the assessment. The questionnaire gathers questions about the following areas: Reading and writing problems (trouble reading and writing), learning and development problems (poor academic performance), and problems with psychomotricity and skills.

Diagnostic criteria for teens 13-17 years-old

It is made up of a series of simple questions that can be completed a parent or guardian. The questionnaire gathers questions about the following areas: Reading and writing problems (trouble understanding written text), learning and development problems (low academic performance), and problems with psychomotricity and spatial skills (poor spatial management), or problems with social relationships (frustration, low self-esteem).

Diagnostic criteria for adults

It is made up of a series of simple questions that can be completed by the user him or herself, or by the professional in charge of the assessment. The questionnaire gathers questions about the following areas: Reading and writing problems (trouble understanding written text, poor handwriting), trouble with professional and social areas (difficulty presenting written projects or writing in public), academic history (childhood academic difficulty), spatial and temporal organization (lateralization, problems with spatial orientation).

Description of the neuropsychological factors affected by dyslexia

Alterations is some cognitive skills may be an indicator of dyslexia. A general profile of the user's cognitive skills may indicate how severe the alterations caused by dyslexia are.

Problems with reading and writing and spatial and motor skills, as well as socialization and social relationships, can be caused by deficits in different cognitive skills. These are the cognitive skills and areas assessed by the Cognitive Assessment Battery for Dyslexia (CAB-DX):

Evaluation tasks

This multi-dimensional scientific resource uses multiple evaluation tasks. Here you can see examples:

Decoding Test VIPER-NAM

This evaluation task integrates notions of the classic Korkman, Kirk and Kemp test of 1998 (NEPSY). It measures the naming capacity, response time and processing speed, measuring the number of cognitive resources that the user allocates to the exercise of decoding, recognizing and understanding stimuli in an efficient way.

Programming Test VIPER-PLAN

This task is based on the classic Tower of London (TOL) and Hooper Visual Organization Task (VOT) by Hooper (1983) tests. It will help observe how the person organizes and plans an action. In order to do this, the user must be adaptable, flexible, and be able to anticipate. It evaluates the success rate of the user when planning an action to achieve a goal.

Sequencing Test WOM-ASM

The Sequencing Test WOM-ASM was based on Conners' classic test (CPT) and the Wecshler Memory Scale (WMS) test of direct and indirect digits. Using these tests, we are able to observe the temporary storage capacity and, above all, the capacity to manipulate information to perform higher cognitive tasks, such as language comprehension or reasoning.

Concentration Test VISMEN-PLAN

This evaluation task is inspired by the Wechsler Memory Scale (WMS) direct and indirect digits test, the classic Memory Malingering Test (TOMM) and the classic Tower of London Test (TOL), allowing to measure planning capacity, visual memory, short-term memory, response time, working memory and processing speed, among others.

The brain and dyslexia

Dyslexia affects 10% of the global population, affecting people’s ability to read, write, and easily decode the written alphabet in general. There are about 700 million adults and children with this learning disorder, and luckily, technological advances in neuro-imaging have made it possible to understand more about the brain and dyslexia than ever before. Some of the brain structures affected by this language learning disorder are:

Angular gyrus and supramarginal gyrus

These are made up of a multimodal associative area located in the temporal-parietal lobe that received auditory, visual, and somatosensory information. In these regions, the neurons are specifically oriented to process the phonological and semantic aspects of language, which makes it possible to identify and categorize words.

Wernicke’s Area

It is located behind the primary auditory cortex, near the beginning of the lateral ridge in the left hemisphere. This area is part of the associative cortex, and makes it possible to give meaning to the things that you hear or see.
