Executive functions develop during the first years of life and determine, to some extent, future learning and personal development. Executive dysfunction is related to various neurodevelopmental disorders, so its study is of great interest for intervention in both children with neurotypical development and those who have suffered a neurodevelopmental disorder. Alterations in executive functions are also related to age-related decrepitude and cognitive rehabilitation and active aging programs. The literature on executive function, its development and the problems arising from its impairment can be found in a variety of publications. This book integrates this information into a single publication with the most recent knowledge related to the neurocognitive development of executive functions and their implication in the daily activities of clinicians, rehabilitators, educators and other professionals. This book is ideal for special education professionals, health professionals in general and mental health professionals in particular, psychologists, educators, speech therapists, occupational therapists, physiotherapists, academics, researchers, students and more.
