title: [Adverse Sensory Input of Childhood Maltreatment Modified by Early Experience Ascertaining the Neural Basis of Neurodevelopmental and Attachment Disorders].
abstract: Childhood maltreatment, which markedly increases the risk of psychopathology such as depression, PTSD, and reduced cognitive abilities, is associated with structural and functional brain differences. Our earlier studies elucidated potential discernible effects on the brain morphology of childhood maltreatment on the gray matter volume or cortical thickness. Further, our preliminary studies revealed a significantly reduced gray matter volume (GMV) in the left primary visual cortex (Brodmann area 17) in the reactive attachment disorder (RAD) group compared to the typically developed group. These visual cortex GMV abnormalities may also be associated with such visual stimulus-induced emotion regulation impairments of RAD, leading to an increase in the risk of future psychopathology. Brain regions that process and convey the adverse sensory input of the abuse might be modified specifically by such experiences, particularly in subjects exposed to a single type of maltreatment. Thus, exposure to multiple types of maltreatment is more commonly associated with morphological alterations in corticolimbic regions.
