HOW DOES EARLY CHILDHOOD TRAUMA AFFECT COGNITIVE DEVELOPMENT AND MENTAL HEALTH IN ADULTHOOD?

This research paper deals with the long-term effect of early childhood traumas on cognition and mental health in adults. Traumatic episodes during the years of childhood, due to abuses, neglect, and exposure to other forms of violence, caused enormous differences, sometimes for one's lifetime, in ways in which brains develop, further implicating high-order cognition, such as memory and attentional resources, by affecting decision-making capability. This paper reviews the literature linking early trauma to changes in key areas of the brain, such as the prefrontal cortex and hippocampus. It examines the link of neurobiological changes with the incidence of various disorders later in life, including major depression, anxiety, and post-traumatic stress disorder. The approach of this review is integrative, combining developmental psychology and neuroscience with clinical research in discussing mechanisms whereby trauma sets a course for later life's cognitive and emotional outcomes. The results emphasize how early intervention and trauma-informed care are decisive factors in reducing the lifetime effects of childhood adversity.
