There is much evidence of the many risks posed by childhood neglect. A scoping review of the literature found 467 articles on 345 studies from 38 countries reporting a large number of problems for children and adults associated with childhood neglect. After describing the broader scoping review, this paper presents findings specific to physical health, neurobiology and development. Across different neglect sub-types, different populations and different research methods, the weight of research demonstrates substantial risk from neglect including, at the most extreme, fatal outcomes for children. Physical health problems associated with neglect cover many health areas including the cardiovascular, respiratory and central nervous systems for children and adults. Studies from neuroscience have also shown wide-ranging atypical neurobiological structures and networks following different neglect sub-types especially for children exposed to institutional neglect. Similarly, studies have reported many developmental outcomes associated with neglect especially related to cognitive development. Physical health, neurobiology and general development are interrelated in healthy childhood and in the presence or aftermath of childhood neglect.
