Shake it off? Not so easy for people with depression, new brain research suggests

Getting rejected hurts depressed people for longer, U-M/Stony Brook/UIC study finds — due to the lack of a natural pain & stress-reducing chemical

Rejection's Effect on a Depressed Brain & a Healthy One
The brains of healthy individuals (left column) released natural opioids during social rejection (colored spots) that may help to reduce negative emotions associated with rejection. In contrast, study participants with depression (right column) did not release nearly as many opioids, which may contribute to a lingering depressed mood following rejection.
