Interrelations between pain, stress and executive functioning

The purpose of this narrative review is to discuss the interrelations between pain, stress and executive functions.

Self-regulation, through executive functioning, exerts control over cognition, emotion and behaviour. The reciprocal neural functional connectivity between the prefrontal cortex and the limbic system allows for the integration of cognitive and emotional neural pathways and then for higher-order psychological processes (reasoning, judgement etc.) to generate goal-directed adaptive behaviours and to regulate responses to psychosocial stressors and pain signals. Impairment in cognitive executive functioning may result in poor regulation of stress-, pain- and emotion-related processing of information. Conversely, adverse emotion, pain and stress impair executive functioning. The characteristic of the feedback and feedforward neural connections (quantity and quality) between the prefrontal cortex and the limbic system determine adaptive behaviour, stress response and pain experience.
