Quantitative EEG is a direct measure of the electrical energies of the brain which are produced by synapses on the dendrites and cell bodies of cortical pyramidal cells. The network dynamics necessary for proper function of the brain can be disrupted following a traumatic brain injury and can persist for years following even apparently minor injuries with no associated loss of consciousness.
The three most consistent findings on QEEG in patients with traumatic brain injury include:
1) reduced power in the higher frequency bands which is usually linearly related to the number of neurons involved in the injury;
2) increased slow waves in the delta frequency band usually only in the more severe cases, and
3) changes in QEEG coherence and phase delay which are directly related to the magnitude of the injury both in the grey and the white matter.
In this paper I present changes in the QEEG of a 25-year old man undergoing a conservative treatment regime which included manipulation, visual imaging, neurological rehabilitation, and nutritional supplementation.
