Hippocampal volume loss in depression reflects glial loss
Depression has been associated with reduced volume of the hippocampus in magnetic resonance imaging studies in humans. A new study now clarifies the cellular basis of these volumetric changes, which have been unclear until now. Beginning in the 1980s, a series of studies in rodents suggested that an area of the hippocampus, a brain region implicated in mood and memory, was particularly vulnerable to stress. When analyzing the brain tissue in detail, they reported loss of nerve cells called neurons with stress.

Relatively few get help either before or after deployment.
