Abstract

Lasting effects of child abuse and neglect are well recognised. Apart from physical effects resulting from injuries and neglect, the effects are on behaviour, emotional well-being, interpersonal relationships and cognitive functioning. These psychological aspects are now known to have their counterparts in brain structure, chemistry and function. The growing knowledge of brain development has shed new light on our understanding of the processes by which especially early abuse and neglect may have a profound effect on the child's later adjustment. The brain undergoes its greatest growth and development in the first years of life, (with a second phase in adolescence). While the sequence of development within the brain is genetically determined, the nature of this development is determined to a considerable extent on the young child's experiences. The absence of some experiences, such as extreme deprivation during sensitive periods of development may mean that certain functions will not develop. For most functions, the nature of experience will shape brain development. Negative experiences and certain ways of interaction will be incorporated into the brain's connectivity. While learning and new experiences continue throughout life, and their effects continue to be incorporated into brain structure and functioning, previous patterns cannot be erased, only added on to and more slowly. As we know from our adult experiences, learning is far faster in childhood. A further aspect of child maltreatment which has a profound effect on brain development is the significant neurobiological stress which the young, maltreated, child experiences. It is interesting to learn that secure attachment organisation protects the developing brain from the worst effects of the stress response. The effects of the experiences interact with the child's genetic resilience or vulnerability.
