Key findings

  • Among 50 ADHD patients, 30% showed excess central or frontal delta-theta, 25% excess frontal beta and 45% excess posterior or central alpha
  • Training began with sensorimotor rhythm (SMR, 11-13 Hz) enhancement and theta (4-8 Hz) inhibition, then shifted to subtype-specific protocols
  • Training was reported to lower theta amplitude, raise beta amplitude and change the theta/beta ratio and brain rate
  • Brain rate is proposed as a complementary feedback parameter reflecting the whole EEG spectrum

A clinical paper on the author's experience combining psychological testing with EEG and QEEG in children and adolescents with psychological disorders (ADHD, obsessive compulsive disorder, anorexia) and somatopsychic conditions (dehydration, lead toxicity). Besides standard measures, she uses 'brain rate,' a spectrum-weighted mean frequency, as an arousal index and neurofeedback parameter. In 50 children with ADHD, QEEG subtypes were identified and neurofeedback was given. The author concludes an individualized approach is key but cannot replace clinical competence.
