A technical guide by Jay Gunkelman, QEEG-D
General comments:
There is a generally reciprocal effect between alpha and beta, as brain stem stimulation desynchronizes the alpha generators, beta is seen. During states of under-arousal, this relationship is not seen, as when the subject is alerted, when both alpha and beta increase.
The point is that the arousal level [...]

Neurofeedback Impacts on Addiction
According to the U.S. Substance Abuse and Mental Health Services Administration, addiction is currently one of the most significant health and social problems in America, affecting ~12.5% of the population. Medical costs can be up to 300% higher for an untreated alcoholic than a treated alcoholic. Other costs to society have reached almost $500 billion, [...]
Why do a qEEG for Neurotherapy?
There are many in the field of Neurotherapy who do not perform qEEGs prior to designing a clinical intervention. These people are currently practicing well within the standard of practice for this rapidly evolving field. Many within this group have standard protocols which are used on all clients, with various alterations to respond to the [...]
Patterns seen in the qEEG and their indicated interventions
Diffuse slowing, with slower alpha
The ascending reticular activating system stimulates the diffuse thalamic projection system and sets the general arousal level of the brain. With an increase in the CNS arousal level, there is an increase in the mean frequency of alpha and a decreased slowing. With decreases in arousal there is a slowing of [...]

P300 Abnormalities in Cocaine, Methamphetamine, Heroin Addiction, and Alcoholism
The P300 component of the ERP, occurring 300–600 ms post-stimulus, is the most widely used ERP in psychiatry and other clinical applications (Polich et al. 1994; Polich and Herbst 2000; Pritchard 1981, 1986; Pritchard et al. 2004). The amplitude of the P300 reflects the allocation of attentional [...]
