I would be extreemely skeptical of any physician who tells you that he knows what types of thoughts you are having based on an EEG pattern. The brain is an incredibly complex system, and the EEG is a very crude means of measuring a amall amount of the activity it generates. Understanding the brain using only EEG has been likened to understanding the working of a Formula One race car using a transistor radio. I say this tongue in cheek since much of my disseration will be using EEG measures of perceptual activity. As a scientist, I would be wary of those claiming to offer behavioral modification or bio-feedback treatments based on EEG as treatment for criminal thoughts, particularly if they are expensive and not covered by insurance. I am not claiming that these do not work, but I am unaware of any studes that have shown this to be effective at modifying behavior or thought patterns. If you are looking for scientific journal articles as to appropriate use of EEG in criminal behavior diagnosis or modification, I would look at the epilepsy litereature. There has been some increase in legal defenses claiming that criminal behavior was the result of epileptic activity and thus not voluntary. This is very rare and if thought to exist, should be evaluated by a neurologist with significant expertise in epilepsy. A typical evaluation should include combined EEG and video documentation of the behavior and a thorough neurologic and psychologic history. This behavior should be aggressive and this aggressiveness should be characteristic of the patient's habitual seizures. (Treiman DM., Epilepsia. 27 Suppl 2:S77-104, 1986.)
