The results revealed that findings are becoming increasingly nuanced with variations in levels of evidence related to ages of the children and characteristics of the specific treatment .
In addition , we focused our critique on generalization of treatment effects across setting s and time and on sample diversity ( with regard to ethnicity and levels of parent education ) in relation to the population .
Children of parents with higher levels of education than average appear to be overrepresented in the literature .
The purpose of this research was to up date the series of articles on evidence -based treatment for children and adolescents with attention deficit/hyperactivity disorder that have appeared in this journal ( Evans , Owens & Bunford , 2014 ; Pelham & Fabiano , 2008 ; Pelham , Wheeler , & Chronis , 1998 ) .
Distinct EEG effects related to neurofeedback training in children with ADHD: a randomized controlled trial.
In a r and omized controlled trial , neurofeedback ( NF ) training was found to be superior to a computerised attention skills training concerning the reduction of ADHD symptomatology ( Gevensleben et al. , 2009 ) . The aims of this investigation were to assess the impact of different NF protocol s ( theta/beta training and training of slow cortical potentials , SCPs ) on the resting EEG and the association between distinct EEG measures and behavioral improvements . In 72 ( of initially 102 ) children with ADHD , aged 8 - 12 , EEG changes after either a NF training ( n=46 ) or the control training ( n=26 ) could be studied . The combined NF training consisted of one block of theta/beta training and one block of SCP training , each block comprising 18 units of 50 minutes ( balanced order ) .  Spontaneous EEG  was recorded in a two-minute resting condition before the start of the training , between the two training blocks and after the end of the training . Activity in the different EEG frequency b and s was analyzed . In contrast to the control condition , the combined NF training was accompanied by a reduction of theta activity . Protocol -specific EEG changes ( theta/beta training : decrease of posterior-midline theta activity ; SCP training : increase of central -midline alpha activity ) were associated with improvements in the German ADHD rating scale . Related EEG-based predictors were obtained . Thus , differential EEG patterns for theta/beta and SCP training provide further evidence that distinct neuronal mechanisms may contribute to similar behavioral improvements in children with ADHD
