What is pediatric neuropsychology?

Pediatric neuropsychology is the study of the relationship between brain health and behavior in children. Clinical neuropsychologists conduct assessments of intellect, executive functioning, academics, and social skills to develop a comprehensive understanding of how your child's brain relates to their ability to reach their potential. Each child is unique, and our clinical neuropsychologists strive to figure out what makes your child tick.
