    Alpha, theta and alpha-theta enhancements are effective treatments of the anxiety disorders. Alpha suppression is also effective, but less so.

Evidence-based medicine evaluation of electrophysiological studies of the anxiety disorders
"Common to most of the anxiety disorders is basal instability in cortical arousal, as reflected in measures of quantitative electroencephalography (qEEG). Resting electroencephalographic (EEG) measures tend to correlate with symptom sub-patterns and be exacerbated by condition-specific stimulation. Also common to most of the anxiety disorders are condition-specific difficulties with sensory gating and the allocation and deployment of attention. ... Electrophysiological measures of function are likely to play a significant role ... in securing improvements in nosological and treatment specificity."

  • Quantitative EEG analysis in obsessive compulsive disorder
    Relative theta activity was increased and alpha was decreased, particularly in frontotemporal areas.

  • Quantitative EEG in obsessive-compulsive disorder
    Lower activity in delta, beta1, and beta2 at frontal and right-hemisphere sites. Greater homologue asymmetries in EEG activity, indicating severe right hemisphere EEG hypoactivity especially in the beta2 band.
  • Quantitative electroencephalographic subtyping of obsessive-compulsive disorder
    Two subtypes: (1) excess relative theta activity especially in frontal and frontotemporal sites; (2) increased relative alpha activity.
