A new study reports teens faced with chronic family stress have higher blood pressure and worse immune response to bacterial infections. However, those who used cognitive reappraisal had lower blood pressure, despite the pressures they faced.
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.
