Executive Function in Down Syndrome: Links to Adaptation and Treatment Implications

This chapter presents a review of existing research regarding the presentation of executive function in persons with Down syndrome. Contemporary scientific work regarding the development of executive function in persons with Down syndrome is reviewed, with an emphasis on profiles associated with childhood, adolescence, and adulthood. The valid assessment of executive function and methodological considerations are also discussed, including the importance of developing phenotype-sensitive and reliable measures of executive function that account for the broader profile of strengths and challenges associated with Down syndrome. Future areas of research are identified that can inform intervention approaches to target the development of goal-directed behavior and adaptation in this population.
