qEEG is a non-invasive technique to measure some of this electrical activity in the brain using a cap with electrodes.
Brain activity is recorded for 5 minutes with eyes open and 5 minutes with eyes closed during a 1 hour appointment. Afterwards, a complete report of the results is generated showing one’s brain activity traits compared to what is age/gender typical and healthy.
These results can be used in a number of different ways:
Here is a common pattern in Depression:
Delta waves are slower wave forms that are normally highly present during deep sleep. However, in depression, we often find that these slow waves are excessively present in the front of the brain (pre-frontal cortex) even when awake and alert, as seen in RED.
After an acute treatment course of rTMS, this individuals delta waves returned to the levels of those expected in healthy individuals of the same age and gender (shown as green). This improvement in brain wave activity was also associated with a significant improvement in their depressive symptoms.
