Abstract
OBJECTIVE: The present study aims to present and discuss the role of neuropsychological assessment (NA) in the investigation of neurodevelopmental disorders (NDDs), with an emphasis on early diagnosis, on the steps that make up the evaluation process, and on the resources that complement clinical evaluation. Furthermore, the discussion is expanded to specific conditions, such as Attention Deficit/Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD), and Specific Learning Disorders (SLD), considering that they represent frequent assessment demands. DATA SOURCES: A critical review of the national and international literature on neuropsychological assessment in NDDs was carried out, highlighting standardized instruments for the Brazilian context, complementary clinical tasks, and main cognitive and behavioral domains. References to essential books and manuals were included, with analysis enriched by the authors' clinical and teaching experience. DATA SYNTHESIS: NA constitutes a central tool for the early identification of alterations in neurodevelopment, with contributions to diagnosis and to the definition of intervention strategies. The process involves systematic steps, such as detailed anamnesis, application of standardized tests, and behavior analysis, covering different domains. The feedback, the final stage of the process, is essential for the understanding of the results and for adhering to the suggested procedures, and it should guide parents on practical implications, therapeutic and educational recommendations, and necessary referrals. CONCLUSIONS: NA represents an essential resource in pediatric practice, both for diagnostic support and for directing interventions and monitoring the progress of children with NDDs. Its early use can modify the prognosis and promote better functional, academic, and socioemotional outcomes.
