Behavioural differences between EEG-defined subgroups of children with Attention-Deficit/Hyperactivity Disorder

Journal Article


Abstract


  • Objective: This study investigated the presence and nature of EEG clusters within a clinically-referred

    sample of children with Attention-Deficit/Hyperactivity Disorder (AD/HD), and whether behavioural differences

    exist between clusters.

    Method: Participants were 155 boys with AD/HD and 109 age- and gender-matched controls. EEG was

    recorded during an eyes-closed resting condition and Fourier transformed to provide estimates for total

    power, and relative delta, theta, alpha, and beta. EEG data were grouped into 3 regions, and subjected to

    Cluster Analysis. Behavioural data for each cluster were compared against the remaining AD/HD subjects.

    Results: Four EEG clusters were found. These were characterised by (a) elevated beta activity, (b) elevated

    theta with deficiencies of alpha and beta, (c) elevated slow wave with less fast wave activity, and (d) elevated

    alpha. An exploratory analysis of behavioural correlates with these EEG subtypes indicated the

    presence of interesting trends that need further investigation.

    Conclusions: This study found that the AD/HD EEG profiles reported in past studies are robust and not

    substantially affected by the inclusion of children with other comorbid conditions. The observed group

    differences in behavioural profiles indicated that different patterns of EEG activity have importance in

    determining behaviour.

    Significance: This is the first study to link behavioural profiles of children with AD/HD to specific EEG

    abnormalities.
