QEEG-Guided Neurofeedback for Anger/Anger Control Disorder

Previous observations suggested that chronic anger may be associated with persistent excessive high-frequency beta activity in one or more cortical areas and that poor anger control may be associated with excessive slowing of the EEG. We hypothesized that downtraining of elevated high-frequency beta activity would reduce anger and that downtraining of excessive cortical slow wave activity would improve anger control. Forty-six individuals underwent neurofeedback training to downtrain excess beta and slow wave activity. This protocol resulted in significantly improved anger control and a reduction in the frequency of outbursts.

Chapter 7 – Neurofeedback and Epilepsy

Publisher Summary This chapter introduces the published research on neurofeedback and epilepsy, followed by a description of the clinical protocols typically used and illustrated with case examples when appropriate. Then, the use of qEEG (electroencephalography) to improve outcome is described. The research on neurofeedback and epilepsy has historically been limited (of necessity) to small sample sizes and only a single group for which pre- and post-treatment effects are determined. One exception was a study using SCP, which was a controlled study with between-group comparisons. Despite these limitations, results have been consistent across studies, generally suggesting that neurofeedback leads to reduction in seizures. The chapter argues that the studies utilizing SCP training, though not as numerous, also show positive outcomes.

Is It Better to Train Power First or Coherence First

ABSTRACT Introduction. This study was done to see to what extent power training would correct coherence abnormalities in head-injured patients and to what extent coherence training would correct power abnormalities in a similar group of head-injured patients. Method. Ten patients had power training first, and 10 patients had coherence training first (4 protocols with 5 sessions/protocol in each case). Results. Either power or coherence training first resulted in normalization of most power and coherence abnormalities. Coherence training first resulted in significantly more new power abnormalities (10/client vs. 5/client for new power abnormalities). Power training first resulted in significantly more new coherence abnormalities (6/client vs. 2/client). Conclusion. We did not find a clear-cut advantage for doing either power or coherence training first. However, we would recommend a repeat QEEG after doing either power or coherence first, since most original abnormalities will have resolved and there are l...
