Why are people who recover from major depression never really out of the woods?
...nerability for further episodes. Now we've found a clue using brain imaging that may point to a depression trait marker that underlies this vulnerability." This 'depression trait marker' involves two brain regions: the subgenual cingulate and the medial frontal cortex. These brain regions are located in a...Jefferson scientists find evidence of greater sensitivity to addictive drugs in adolescence
...so we will be looking to see if this increase is a clue to sensitivity to addiction and sensitivity to such drugs as therapeutic agents," says Dr. Ehrlich.
