Early severe institutional deprivation is associated with a persistent variant of adult attention‐deficit/hyperactivity disorder: clinical presentation, developmental continuities and life circumstances in the English and Romanian Adoptees study

Abstract

We provide the first evidence of a strong persistence into adulthood of a distinctively complex and impairing deprivation-related variant of ADHD. Our results confirm the powerful association of early experience with later development in a way that suggests a role for deep-seated alterations to brain structure and function.
