“…The procedures used and results have been described previously for this sample. 6 Briefly, participants were evaluated while resting in the eyes-closed, maximally alert state in a sound-attenuated room. An electrode cap (ElectroCap, Eaton, Ohio) with 35 recording electrodes was placed according to the International 10–20 System and was used to record EEG data.…”

“…1 It is only in the last decade, however, that researchers have examined the effects of methamphetamine on the human brain. For example, the neurobiological abnormalities associated with long-term, high-dose methamphetamine exposure have been described using various neuroimaging 2–5 and electrophysiological 6 techniques. The functional consequences of long-term, high-dose methamphetamine exposure are also reasonably well-established, and include marked deficits on measures of episodic memory.…”

“…We hypothesized that poorer performance on episodic memory tests would be associated with increased theta power, an index of neurobiological abnormality, based on previous work that has demonstrated this association 8 and other studies showing that methamphetamine-dependent individuals demonstrated increased theta absolute power. 6 …”

This study examined the association between brain electrical activity, measured using quantitative electroencephalography (QEEG), and performance on measures of episodic memory in a sample of nine methamphetamine-dependent individuals who were evaluated after 4 days of monitored abstinence and 10 non-drug-using comparison subjects. In methamphetamine users, but not in comparison subjects, increased theta power was correlated with poorer performance on the delayed recall subtests of the Rey Auditory Verbal Learning Test and the Rey-Osterrieth Complex Figure Test (p<0.05). There was no association between alpha, beta, and delta power and performance on the memory tests. These results complement previous findings by demonstrating that the electrophysiological abnormalities associated with methamphetamine dependence are likely to affect behavior in an observable and important manner (i.e., memory deficits) when users are not intoxicated.

“…Several studies have examined the neurobiological consequences of methamphetamine dependence using qEEG methods (e.g., Newton et al, 2003;Newton et al, 2004). It was found that methamphetamine dependent patients exhibited a significant power increase in the delta and theta bands as compared to non-drug-using controls .…”
