Parenting a child with attention deficit hyperactivity disorder (ADHD) can lead to increased stress when social support is lacking. A recent meta-analysis of 44 studies found that parents of children with ADHD experienced significantly more stress than both a non-clinical control group and parents of children with other disorders, including learning disability, developmental delay and autism spectrum disorder. Parenting stress was divided into two domains: characteristics of the child and parental functioning. As it was the child domain that was elevated, it is likely to be the symptoms and characteristics of ADHD that lead to increased levels of stress.
