In chronic pain and depression, chronic exposure to stress is a common factor that may produce long-lasting changes (i.e., maladaptive neuroplasticity) in highly sensitive brain areas such as the prefrontal cortex and the hippocampus and in their functional connections, which may underlie the cognitive and behavioral impairments accompanying these conditions (Teffer and Semendeferi, 2012
