People with opioid dependence in recovery show ‘re-regulation’ of reward systems

9 diciembre 2014

Within a few months after drug withdrawal, patients in recovery from dependence on prescription pain medications may show signs that the body’s natural reward systems are normalizing, reports a new study. In brain activity studies, patients with recent drug withdrawal showed heightened responses to drug-related cues, such as pictures of pills. In the extended-care patients, these increased responses to drug cues — in a region of the brain called the prefrontal cortex, involved in attention and self-control — were significantly reduced.
