Brain Mapping (Quantitative EEG) -Emerging
Clinical Applications

Definitions

• Electroencephalogram(EEG)-brain related
  electrical potentials recorded from the scalp
• Brain Mapping (QEEG)-Mathematical processing of
  digitally recorded EEG in order to highlight
  specific waveform components and better
  visualization of the EEG tracing
• Neurotherapy-set of neurophysiologicaly based
  methods for modifying brain functions-includes
  EEG-biofeedback (neurofeedback) and other
  modalities as trans-cranial magnetic and electric
  stimulation and deep brain stimulation (useful
  especially in tremor and Parkinsons disease),
  and electroconvulsive therapy -ECT

Brodmann cortical areas 1909

• Described by Dr. Brodmann approximately 100 years
  ago but still widely used in research and
  clinical practice which links specific cortical
  brain areas to particular functions

Clinical usefulness of QEEG in general neurology
practice

• 150 subsequent QEEGs were analyzed for a
  potential clinical usefulness in general
  neurology practice (defined as either
  contributing to diagnosis or medical decision
  making or treatment).
• Most cases were divided to 5 groups-seizure, TBI,
  HA, dementia, or behavioral problems
• 95 of patients-QEEG contributed to diagnosis or
  treatment.

Need for other modalities

• Medications are not always effective-medication
  resistance
• Staffing the turkey with Prazac is not always the
  best option
• Consider Neurofeedback
