Background: Self-neglect is a significant global public health issue, compromising the health, safety, and well-being of older adults. Despite extensive research on the prevalence and risk factors of self-neglect, the underlying psychosocial mechanisms remain underexplored. Social isolation and aging attitudes have been identified as important correlates of self-neglect; however, the precise interplay between these variables, particularly the mediating role of aging attitudes, has yet to be fully examined in the context of rural older adults.

Article Synopsis
  • The study explores how childhood maltreatment (CM) affects brain development in adults, using MRI data from 214 participants.
  • CM seems to result in accelerated brain aging in younger adults, while older adults show signs of delayed brain development compared to those without CM.
  • The findings suggest that types of maltreatment, such as abuse versus neglect, have distinct impacts on neurodevelopment, and CM is linked to increased attentional impulsivity in affected individuals.
