Abstract

|
|
Objectives ： In this study, authors investigated the neurophysiological effect of biofeedback training in patients with methamphetamine dependence using quantitative EEG (qEEG).
Methods： Methamphetamine-dependent patients willing to receive biofeedback therapy were recruited in an addiction ward. qEEG measurements were conducted before and after each training session. Theta (4-8 Hz) relative power was measured and compared before and after biofeedback qEEG of each session.
Results： A total of 49 pairs of relative power before and after biofeedback qEEGs were obtained from 11 subjects with methamphetamine dependence. The right temporal theta relative power showed a significant decrease after biofeedback training. The right frontal theta relative power in the early biofeedback training sessions showed a significant decrease compared with the later training sessions. Additionally, the right temporal thetarelative power after the last-biofeedback training session also showed a significant decrease compared with the biofeedback before the first training session.
Conclusion ： These results suggested that the application of biofeedback training program changed brain waves and thus, could be a useful method of treatment for methamphetamine dependence.
