Anxiety and Children with Fragile X Syndrome

By Kathleen Holder

Anxiety is a common problem for children and adults with fragile X syndrome, magnifying their struggles living with an inherited intellectual disability. New UC Davis research could lead to new ways to identify and treat their anxiety at a young age—even in infancy.

The study led by developmental psychologists Jessica Burris and Susan Rivera found that infants and young children with fragile X syndrome, unlike typically developing children, tend to have their attention specifically captured by angry faces rather than happy ones. That sort of “attentional bias” toward angry faces is a pattern associated with anxiety.
