摘要：
Tobacco use remains a major preventable cause of death worldwide, accumulating billions of dollars in healthcare spending annually in the U.S. alone. Evidence has found that among those addicted, individuals suffering with psychiatric illnesses are disproportionally abusing. To assess this disparity, our study observed event related potential (ERP) responses recorded with electroencephalogram (EEG) in chronic smokers with (MI; n=6) and without mental illness (NMI; n=6). We found that the MI group alone presented heightened late positive potential (LPP) responses while processing cigarette (addictive) stimuli compared to neutral images (t-value = 3.11 at Cz, 3.92 at Pz). Our study illustrates the significance of the LPP as a promising biomarker to assess tobacco addiction in individuals facing mental illness.
