Contrary to Diagnostic and Statistical Manual of Mental Disorders (DSM-5), fifth edition, some studies indicate that ADHD-inattentive presentation (ADHD-I) is a distinct diagnostic disorder not an ADHD presentation.In this study, 12 ADHD-combined (ADHD-C), 10 ADHD-I, 13 controls were enrolled their resting state EEG recorded. Following this, graph theoretical analysis was performed functional integration segregation brain network calculated.The results show clustering coefficient theta band significantly different among three groups significant differences observed in global efficiency between ADHD-C. Regarding the alpha band, lower control subjects. In beta children with ADHD-C also ADHD-I The coefficient, subjects ADHD-C, demonstrated rapid decline than control.Decreased clustering, high thresholds, may be associated hyperactivity while increased low thresholds inattentiveness. A occurs consistent several have reported as disorder.
