science π¬ Childhood trauma linked to adult stress via DNA
Scientists discovered an epigenetic mechanism linking childhood trauma to heightened adult stress sensitivity in mice. This research was conducted by scientists studying mice exposed to early-life adversity in the ventral tegmental area. The study involved comparing 18 adult male mice exposed to stress versus standard rearing, with findings published on a date not specified. This vulnerability stems from an increased enzyme that keeps DNA loosely coiled, making the brain hyper-reactive to stressors. Future work aims to use this biological insight to develop new treatments for stress sensitivity. π§
