Abstract
- In this study, we analyzed the quantitative electroencephalograms (EEGs) of forty-eight subjects (18 with methamphetamine dependence and 30 non-methamphetamine users as controls). Immediately following data collection, all personally identifying information was replaced with random numbers to prevent bias and protect privacy. Statistical analysis was performed using SPSS version 20.0 for MS Windows. To investigate the general characteristics of the demographic background of the study subjects, frequency and technical analyses were conducted. Mann-Whitney U tests were performed to determine the difference in quantitative EEGs between methamphetamine users and non-methamphetamine users. Methamphetamine users demonstrated quantitative EEG abnormalities that were consistent with generalized encephalopathy.
