The HBN is an ongoing initiative focused on creating and sharing a biobank of data from 10,000 New York area participants aged 5–21. The HBN Biobank houses multidisciplinary phenotypic data and multimodal brain imaging data. Recruitment for the study is ongoing since 2017, through advertisements that seek the participation of families who have concerns about one or more psychiatric symptoms in their child. Primary causes for exclusion of participation centre on the presence of acute safety concerns, cognitive or behavioural impairments that could interfere with participation or medical concerns that are expected to interfere with brain-related findings.
