Children's Hospital of Philadelphia (CHOP) is the nation's first hospital devoted exclusively to the care of children. Since our start in 1855, CHOP has been the birthplace for countless breakthroughs and dramatic firsts in pediatric medicine. The Neuropsychology and Assessment Service at Children’s Hospital of Philadelphia (CHOP) provides evaluation and consultation services for children with specific medical disorders. The purpose of a neuropsychological evaluation is to understand how medical conditions or treatments involving the brain or central nervous system affect the person’s development, including impacts on cognitive, emotional, and behavioral functioning.

Alice in Wonderland syndrome (AIWS) is a brain-related condition that disrupts how you perceive your own body, the world around you or both. Named for a famous children’s storybook, this rare condition makes things look or feel larger or smaller than they actually are. It can happen for several reasons, many temporary or treatable.
