Brain Responses to Anti-smoking Health Warnings in Youth

Purpose of the Review Adolescents and young adults are a critical target for smoking prevention efforts. Health education is a key approach to these efforts, yet little is known about how adolescents and young adults process health information. One novel approach to understanding the neurobiological mechanisms of cognitive processing of public health communications is to use neuroimaging techniques to map the brain regions involved and make inferences about the neural systems engaged in the processing of health information. We reviewed recent studies that employed functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to examine the brain responses of adolescents and young adults to anti-smoking health messages and videos. Findings This narrative literature review found that the medial prefrontal cortex, amygdala, and hippocampus were the brain regions most commonly engaged in response to health warnings. Developmental factors modulate the relationship between brain regions, regulated emotional reaction, and frontal regions that are responsible for decision making. Summary Research that integrates neurophysiology and behavior to study adolescent and young adult neurocognitive responses to health messaging is an important tool for identifying optimal methods to communicate the health hazards of smoking with this vulnerable population.
