Brief Summary
In recent years, the growing awareness of the multifactorial nature of neurodevelopmental disorders has stimulated interest in transdiagnostic approaches aimed at investigating underlying etiological mechanisms beyond traditional diagnostic categories. In this context, the present study seeks to provide a transdiagnostic profiling of both domain-general cognitive functions (attention, working memory, executive control) and domain-specific functions (phonological awareness, rapid naming, vocabulary, reading) underlying the main neurodevelopmental disorders in a large sample of preschool and school-age children (3-11 years), through the use of CRAB (Computerized Reading-related Assessment Battery). CRAB is a digital platform specifically developed by SUPSI and the Université de Genève to integrate, within a single testing environment, the assessment of the main domain-general and domain-specific cognitive functions underlying neurodevelopmental disorders. In particular, participating families will receive an email containing a link to access the CRAB platform, which will not include their personal data but rather a code provided by the staff of IRCCS Medea. A screen will open displaying several game-like tasks designed to measure both domain-general and domain-specific cognitive functions, which must be completed by the participating subject. The main objective is to obtain a fine-grained and multidimensional mapping of cognitive profiles prior to the standard diagnostic process, in order to identify early patterns of (a)typical or at-risk functioning.

6 MONTHS
VISUAL ORTHOGRAPHIC
the ability to visually process both orthographic (letter-based) and non-orthographic (symbol-based) stimuli (accuracy) as ad hoc developed within CRAB

Interventions
CRAB (Computerized Reading-related Assessment Battery). CRAB is a digital platform specifically developed by SUPSI and the Université de Genève to integrate, within a single testing environment, the assessment of the main domain-general and domain-specific cognitive functions underlying neurodevelopmental disorders
Eligibility Criteria
The study population consists of children referred for the first time to the Territorial Unit of Child and Adolescent Neuropsychiatry (NPIA) at IRCCS Eugenio Medea - Associazione "La Nostra Famiglia", Bosisio Parini (LC), for suspected neurodevelopmental or psychopathological disorders. The project will be proposed to all children aged 3 to 11 years (from the first year of preschool to the fifth year of primary school). This is a heterogeneous population reflecting the variety of profiles typically seen in neuropsychiatric services, including suspected neurodevelopmental disorders (e.g., reading disorders, ADHD, language disorders, developmental coordination disorder), learning difficulties, or other clinical concerns. The study does not involve interventions or group allocation, but only a single digital data collection via CRAB prior to the standard diagnostic process.
You may qualify if:
- Age between 3 and 11 years;
- First access to the NPIA service at IRCCS Eugenio Medea (Bosisio Parini);
- Suspected neurodevelopmental or psychopathological disorder;
- Completion of the standard clinical diagnostic pathway;
- Availability of a compatible device (tablet or computer) for remote administration, if applicable.
You may not qualify if:
- Age outside the specified range;
- Failure to complete the diagnostic pathway;
- Lack of access to a compatible device (for remote administration);
- Severe sensory impairments (uncorrected blindness or deafness);
- Motor impairments preventing use of digital devices;
- Significant lack of understanding of the Italian language affecting task comprehension.
