In 2009 the National Institute of Mental Health (NIMH) introduced the Research Domain Criteria project (RDoC) which sought to analyze basic dimensions of functioning that underlie human behavior to find new ways of studying mental disorders. The purpose of this study was to investigate the relationship between arousal systems and behavioral dimensions. Specifically, this study analyzed spindling excessive beta (SEB) and its relation to insomnia, impulsivity/hyperactivity and attention. The results found an SEB occurrence in patients between 0-10.8%. It was found that patients with frontal SEBs only had significantly higher impulsivity/hyperactivity and insomnia complaints. To conclude, this data reveals that frontal SEB may be an electroencephalographic marker caused by sleep maintenance problems with concurrent impulse control problems.
