QEEG coherence-guided neurofeedback

Key findings

  • Imaging studies show both over- and underconnectivity in ASD, for example reduced anterior-posterior connectivity at rest
  • An early EEG study found atypical lateralization in 7 of 10 autistic children
  • A computerized EEG study of 11 autistic children found greater interhemispheric beta coherence than in comparison groups
  • Author argues connectivity-guided neurofeedback can reduce symptoms, illustrated with a case example

A review of evidence that autistic spectrum disorder (ASD) involves abnormal brain connectivity, with some regions excessively connected and others underconnected. The author surveys neuroimaging and EEG coherence research and describes neurofeedback guided by QEEG connectivity data, presenting empirical data and a case example. He concludes that this approach raises hope for a behavioral, psychophysiological intervention that lessens the severity of ASD.
