The Cognitive Assessment for Dyslexia Patients (CAB-DX) is a leading professional tool made up of a battery of tasks aimed at quickly detecting and assessing the presence of symptoms, traits, or poor functioning of the cognitive processes affected by dyslexia.
Dyslexia tends to be underdiagnosed. However, this learning disorder creates significant and persistent difficulties that affect linguistic abilities associated with reading and writing. A neuropsychological test, a clinical history and an evaluation of different dyslexia areas are still the most effective tools to diagnose dyslexia. Note that CogniFit does not directly offer a medical diagnosis of dyslexia. This complete dyslexia cognitive test should be used to complement a professional diagnosis, and never as a substitute for a clinical diagnosis.
This innovative dyslexia online test is a resource that helps make a complete cognitive screening, see cognitive strengths and weaknesses, and evaluate the risk index of the presence of dyslexia. This test is perfect for children 7+, teens, and adults. Any user, either professional or personal, can easily use this dyslexia assessment online.
Completing this cognitive dyslexia test takes about 30-40 minutes and a results report from this test will automatically be available for download after completing the evaluation.

With this assessment battery, it's possible to reliably detect a user's risk index of dyslexia in children 7 years and older.
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 from 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 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:
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.
V2_ASSESS_CRITERIOS
V2_ASSESS_CRITERIOS
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.
It is made up of a series of simple questions that can be completed by a parent or guardian, 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.
It is made up of a series of simple questions that can be completed by the user him or herself. 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).
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).

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 for Dyslexia Patients (CAB-DX):
Attention

Divided attention and dyslexia. Divided attention is the ability to pay attention to more than one stimuli at the same time, like listening to a teacher while writing notes. People that have alterations in divided attention use more cognitive resources when doing two or more tasks simultaneously, which would make it difficult to listen to a lecture and take notes.

Focused attention and dyslexia. Focused attention is the ability to focus attention on a target stimulus, regardless of the duration. You might use focused attention when listening in class or reading a book. When you get distracted, it increases the probability of missing important information, which may affect comprehension and learning. Children and adults with dyslexia may have difficulties paying attention to present stimuli

Short-term memory and dyslexia. People with dyslexia may have alterations in this cognitive skill. Short-term memory is the ability to hold onto a small bit of information over a short period of time, like when remembering the beginning of a sentence to understand the entire phrase. Problems with short-term memory may impede one’s ability to understand what is being said, as the information isn’t processed correctly.

Visual short-term memory and dyslexia. Visual short-term memory is the ability to retain a small amount of visual information over a short period of time, like letters, words, etc. A problem in visual short-term memory may prevent one from understanding written text, as it would be difficult to remember the beginning of a sentence.

Working memory and dyslexia. It’s important to keep in mind that an alteration in working memory may be a strong indicator of dyslexia. Working memory is the ability to retain and use the information necessary to complete complex cognitive tasks, like language comprehension, learning, or reasoning. A deficit in working memory may imply difficulties when understand written or spoken language.
