[Development of executive functions in preterm children]

Abstract

The rate of children born prematurely has increased considerably in the last few decades, and their developmental outcome remains of great concern. The literature on the impact of prematurity has reported a wide range of cognitive and behavioral problems that may be related to deficits in executive function (EF) skills. EF refers to a series of high-level processes (selective attention, inhibition, set shifting, working memory, planning, goal setting) that develop throughout childhood and adolescence and play an important role in cognitive and social development as well as in school achievement. EF skills have been linked to the prefrontal cortex, as well as to other neural networks and brain regions including the basal ganglia and cerebellum. This paper focuses on studies related to the development of EF and social behavior in children born preterm. The preschool period is a critical time to perform neuropsychological assessment in addition to IQ testing, and to detect the child's specific needs in order to adapt effective intervention to enhance the development of executive processes in these high-risk children.
