The Cognitive Assessment Battery for Dyslexia (CAB-DX) from CogniFit was designed to help assist health professionals in the detection, diagnosis, and intervention of dyslexia. This online dyslexia test  is a tool that allows for a comprehensive cognitive screening of the patient. Sophisticated algorithms assess the user and provide an automated report. This report includes the results gathered by each subject in relation to the deterioration level of the cognitive skills that may be affected by dyslexia.
Online Neuropsychological Assessment Battery- Instrument to help in the detection and diagnosis of dyslexia (CAB-DX)
Neuropsychological assessment for dyslexia
Exhaustively explore the brain functions related to dyslexia.
Exhaustively explore the brain functions related to dyslexia.
CogniFit's cognitive assessment for dyslexia is made up of various blocks of tasks. Each task assesses different cognitive abilities affected by dyslexia.
- Memory area: Working memory, short-term memory, naming, and visual short-term memory.
- Attention area: Divided attention and focus.
- Perception area: Visual scanning.
- Coordination area response time.
- Reasoning area: Planning and processing speed.

- Duration: This battery will take no more than 15-20 minutes
- Points: Automated.
- Target users: Children (6+) and adults.
Assessed neuropsychological areas and their relation to dyslexia
Scientific Documentation: Validated battery of tests
This instrument was designed by using the most recent investigations in the field, receiving satisfactory psychometric properties.
The validity of the tasks used for detecting cognitive impairment in dyslexia has been proven in scientific literature. The tasks are also scientifically validated for their use in clinical samples and scientific controls. They maintain an excellent reliability through repeated testing and cross research designs, such as the coefficient Cronbach's Alpha, reaching results of about 0.9. Studies support that CogniFit improves results after 24 training sessions..
Based on the pathology, one or more of the person's cognitive processes will be affected. With dyslexia, the cognitive abilities that may be affected are assessed based on the following areas.
MEMORY Memory has been linked to dyslexia in many studies. It is made up of a number of areas, although some are more affected than others.
ATTENTION There are diverse functions in attention that may imply the activity of different brain regions specialized in this purpose and organized into a system, but only some of these will be affected by dyslexia.
PERCEPTION This cognitive index ability helps remember words as a whole and uses some areas that may be involved in dyslexia.
COORDINATION According to statistics, some people with dyslexia have motor coordination difficulties. Poor fine motor skills, for example, can cause bad handwriting, laterality problems, or inability to perform certain movements. While this is just one example, there are also other skills related to coordination that are affected by dyslexia.
REASONING Reasoning is known as the ability to relate ideas or concepts and create a conclusion based on an explanation. Those who suffer from dyslexia do not have a reasoning impairment, but they use other, less common ways to come to a conclusion. In other words, the way they are able to arrive to a conclusion, like writing a sentence or reading a text, is different than how other people may do it.
CogniFit's tasks use visual and auditory stimulation to guarantee a simple assessment that is adapted to the user. Within the CogniFit platform, there is also a cognitive rehabilitation tool for dyslexia.
The CogniFit tools cover a number of individual tasks, each one designed to evaluate a specific cognitive ability. The set of tasks form part of a battery of tests that create a comprehensive assessment of the user's cognitive level. The CogniFit team is able to offer advice to recommend the most appropriate evaluation for each person.
It has been shown that to have an effective brain assessment for each individual, the assessment must be personalized for each user. The assessment system for dyslexia ensures the efficiency through the supervision of the user's results and adjusts in real time.
This evaluation process providesmany advantages. It is based on a cognitive assessment model that researches the presence of symptoms in dyslexia. The presence of symptoms is a solid argument for creating a diagnosis in relation to dyslexia, independent from the type of dyslexia. It is a method based on scientific evidence and validated by both healthy populations and populations with some pathology. The cognitive assessment for dyslexia will produce a score for the deficit degree in different assessment areas, which allows us to obtain and track the cognitive level of the patient. The final objective of this assessment is to provide the professional with the best quantitative information presented in graphs, in order to allow them to look at the results and make a diagnosis.
