Hippocampal volume reduction in children with chromosome 22q11.2 deletion syndrome is associated with cognitive impairment

Abstract

Results from this study not only contribute to the understanding of the neuroanatomical variation in DS22q11.2, but also provide insight into the nature and source of the cognitive impairments associated with the syndrome. Specifically, we report that decreases in hippocampal volume may serve as an index of severity for cognitive impairments in children with DS22q11.2.
