          Effects of Chronic Stress Can be Traced to Your Genes

          Chronic stress alters gene activity in immune cells before they reach the bloodstream. The change leads to an overabundance of inflammation, which is linked to many negative health effects, a new study reports.

          Why stress doesn’t always cause depression

          Rats susceptible to anhedonia have more serotonin neurons in the ventral dorsal raphe nucleus. However, activating neurons in the central amygdala reduced the serotonin signaling and lowered the effects of social stress.

          How chronic stress causes brain damage

          Chronic stress causes autophagy in adult hippocampal neural stem cells. This results in a decline of hippocampal neurogenesis. Cognitive deficits and mood disorders that arise as a result of chronic stress are a result of autophagic death of hippocampal neural stem cells.
