The effects of traumatic exposure have been researched for many years and studies have shown that the parts of the brain affected by sexually traumatic experiences in childhood are also linked to many physical and psychological problems, such as depression, posttraumatic stress disorder, somatic complaints and suicide. Neuroimaging studies have provided a breadth of evidence that childhood sexual abuse is related to structural changes in the brain. Taken together, childhood sexual abuse affects brain development, leading to differences in brain anatomy and functioning that have lifelong consequences for mental health. Several limitations of neuroimaging research on childhood sexual abuse are discussed, including a lack of refined and sensitive neuroimaging measures and problems interpreting results of structural imaged subjects with associated psychiatric conditions. Future, large‐scale studies are warranted to examine the type and severity of the sexual abuse and how each of the levels of childhood sexual abuse contributes to structural and functional changes. Furthermore, future studies are needed to control for comorbid psychiatric conditions in order to disentangle the effects of childhood sexual abuse from psychiatric conditions that damage brain development. © 2018 John Wiley & Sons, Ltd. ‘Childhood sexual abuse affects brain development, leading to differences in brain anatomy and functioning that have lifelong consequences for mental health’Key Practitioner Messages Childhood sexual abuse is linked to observable structural changes in the brain. These structural changes in the brain are associated with a myriad number of negative psychological effects. Research is limited in elucidating the role of childhood sexual abuse on brain development, as the bulk of the research has focused only broadly on child maltreatment.
