Key findings

  • In 29 Lyme disease patients, 75% with active disease had abnormal QEEG or evoked potentials, and 54% still showed dysfunction after treatment
  • Lupus patients showed different patterns by symptom type, with reported QEEG sensitivity ranging from 44% to 80%
  • During common migraine attacks, 19 of 22 patients showed reduced alpha over one occipital region, which had resolved when retested at least 7 days later
  • Author favors absolute over relative power measures when planning neurofeedback

A review of EEG and QEEG research on brain-wave patterns in medical conditions, written for neurofeedback clinicians. The author describes abnormal patterns reported in Lyme disease, systemic lupus erythematosus, migraine, irritable bowel syndrome and after cardiopulmonary bypass surgery, as well as in fibromyalgia, chronic fatigue, chemical sensitivity and toxic or radiation exposure. He suggests this literature points to a potential role for neurofeedback in these conditions and informs how training might be done.
