Abstract
22q11.2 Deletion syndrome is a genetic disorder characterized by physiological and
psychological symptoms. This study investigated the role of cortisol on the social
and cognitive impairments in children with 22q11.2. A total of 11 children with 22q11.2
were assessed for baseline cortisol levels and received broad neuropsychological testing.
Results were compared with 11 controls. Children with 22q11.2 had significantly higher
cortisol levels. A significant negative correlation was observed between the general
memory and attention/concentration indices of the Wide Range Assessment of Memory
and Learning, 2nd edition and cortisol concentrations in the control population. These
data provide evidence of a possible causal mechanism that underlies social impairments
in stress disorders.
