Abstract
Neurodevelopmental disorders (NDDs) refer to a series of mental disorders that plague the motor and behavioral development of children in the K12 basic education stage. The etiology and pathogenesis of these disorders remain unclear. Multicenter Children's Brain Development Database under Perinatal Factors (PeriCBD) is established by the State Key Laboratory of Cognitive Neuroscience and Learning, Beijing Normal University, relying on county/prefecture/district central hospitals to collect data on the brain development of children in high-incidence age groups of NDDs. The primary purpose is to construct a data information platform related to brain development patterns and individual differences in children aged 3-10 under perinatal factors. Meanwhile, the platform is expected to provide critical basic data for the national brain development research, predictive diagnosis, and treatment of NDDs in children. This paper takes the data collection work completed in Anyang Maternal and Child Health Hospital of Henan Province and the People's Hospital of Liangping District of Chongqing City as examples to introduce the organizational framework of PeriCBD, and clarify the unified collection, cleaning, and analysis process of subject behavior data and magnetic resonance imaging data. In addition, following the standardization in processes, such as data extraction, conversion, loading of database links, etc., the dataset aims to establish a paradigm for subsequent PeriCBD data collection and database were shown.
