Protocol
QEEG brain mapping and spectrum weighted frequency (brain rate)

Key findings

  • Frontal delta and theta activity was generally elevated compared with the normative database
  • Brain rate at Cz averaged 5.86, significantly below normal and consistent with low mental arousal
  • QEEG changes related to maturation in a nonlinear way
  • Authors tie prognosis to intellectual ability and see neurofeedback as one promising part of combined treatment

A QEEG study of nine young boys diagnosed with autism spectrum disorder, comparing their 19-channel brain maps with an age-matched normative database. The authors also calculated a 'brain rate' (spectrum weighted frequency) at Cz as a marker of overall mental arousal. The children showed excess slow (delta and theta) activity over frontal areas and a brain rate well below normal, which the authors read as under-arousal. They suggest neurofeedback, together with medication, behavior therapy and social support, may bring slight improvements.
