Title:	The neural consequences of combat stress: long-term follow-up.
Authors:	van Wingen, G A, Geuze, E, Vermetten, E, Fernández, G
Source:	Molecular Psychiatry. Feb2012, Vol. 17 Issue 2, p116-118. 3p. 1 Graph.
Subjects:	Follow-up studies (Medicine), Combat stress reaction, Military psychiatry, Amygdaloid body, Health outcome assessment
Abstract:	The article discusses the assessment of combat stress-induced amygdala activity. It provides a detailed account on the results showing that in the absence of combat exposure, stress-induced amygdala hypersensitivity normalizes to the same level as before the combat, whereas perceived threat-dependent changes in amygdala coupling with the dorsal anterior cingulate cortex (dACC) persist. In addition, the changes in amygdala activity were not accompanied by changes in regional brain volume.
