ObjectiveLittle is known about the cortisol awakening response (CAR) in children with attention deficit hyperactivity disorder (ADHD). Here, we examined the CAR in children with ADHD and their mothers before, immediately after, and 4months after an intensive summer treatment program (STP).MethodsParticipants were 37 children aged 7–12years who completed the STP in 2009 and 2010, and their mothers. Daily saliva samples for cortisol measurement were collected twice daily at awakening and 30min afterwards at pre-STP, post-STP, and during a follow-up measurement period. ADHD symptom scores were evaluated by parents, and participants completed the Kid-KINDL^R QOL questionnaire.ResultsCAR was low in children with ADHD before the STP, and increased to the control range 4months after STP. Maternal CAR also tended to increase after STP. Changes in the CAR in children tended to correlate with an improved ADHD inattention scores (p=0.091), physical health (p=0.070), and school life subscales scores in the Kid-KINDL^R (p=0.079).ConclusionWe demonstrated that STP improved the behavior and QOL of children with ADHD. Our results indicate that STP could lead to improvements in HPA axis function, as reflected by increased CAR after STP.
