Children with ADHD tend to be excluded from peer activities due to inattention, hyperactivity and impulsive behavior, resulting in social problems. They have been found to have impaired recognition of emotional expression from other faces.
The research group of Professor Ryusuke Kakigi of the National Institute for Physiological Sciences, National Institutes of Natural Sciences, in collaboration with Professor Masami K. Yamaguchi and Assistant Professor Hiroko Ichikawa of Chuo University first identified the characteristics of facial expression recognition of children with ADHD by measuring hemodynamic response in the brain and showed the possibility that the neural basis for the recognition of facial expression is different from that of typically developing children. The findings are discussed in Neuropsychologia
(available online on Aug. 23, 2014).
The right part of the brain of typically developing children responded to both happy and angry faces. On the other hand, the brain of children with ADHD did not respond.
