Previous functional neuroimaging studies have demonstrated exaggerated amygdala responses and diminished medial prefrontal cortex responses during the symptomatic state in posttraumatic stress disorder (PTSD). ⋯ These results provide evidence for exaggerated amygdala responsivity, diminished medial prefrontal cortex responsivity, and a reciprocal relationship between these 2 regions during passive viewing of overtly presented affective stimuli unrelated to trauma in PTSD.

Comparative Study
Alcohol use disorders among US college students and their non-college-attending peers.
Heavy/binge drinking among college students has become a major public health problem. There is consistent evidence suggesting that young adults in college are drinking more than their non-college-attending peers, but it is still not clear whether they are more likely to suffer from clinically significant alcohol use disorders. ⋯ College students suffer from some clinically significant consequences of their heavy/binge drinking, but they do not appear to be at greater risk than their non-college-attending peers for the more pervasive syndrome of problems that is characteristic of alcohol dependence.
