Elevated Repetitive Behaviors are Associated with Lower Diurnal Salivary Cortisol Levels in Autism Spectrum Disorder
Published March 1, 2013
in Biological Psychiatry
This pilot study examined the relationship between repetitive behaviors (RBs) and cortisol, a hormone that is released in response to stress, in individuals with ASD. Multiple salivary cortisol samples were taken over three days for 21 children with ASD with high and low levels of RBs. Children in both groups showed the same pattern of cortisol change throughout the day, but the overall cortisol levels in the high RB group were significantly lower, suggesting RBs may work to soothe and decrease stress.
