1. The profile shown for this patient (Images 2 – 5) is typical of GAD patients in the South America study who responded positively to the stimulation of acupoints. A decrease in the intensity and frequency of GAD symptoms correlated with shifts toward normal levels of wave frequency ratios in the cortex.
    

2. GAD patients treated with Cognitive Behavior Therapy showed a similar progression, but it required a longer period of time for the frontal cortex to get to near-normal ratios of wave frequencies, and the normalization of the ratios tended to revert toward pre-treatment levels a year after the end of the psychotherapy. This regression was less likely to occur for patients treated with acupoint stimulation.
    

3. GAD patients treated with medications such as alprazolam tended to show little or no cortex normalization, even as symptoms were reduced while the drug was being taken. This suggests that the medication is suppressing the symptoms without addressing the wave frequency imbalances.
    

4. Not captured by these images, but shown by other pre/post-treatment measures, are changes in deeper brain structures that EEG brain maps cannot reach, biochemical changes in ions, neurotransmitters, and hormones, and changes in neural circuits.
