Chronic pain: a consequence of dysregulated protective action

Area of Science:

• Neuroscience
• Psychology

Background:

• Pain and functional neurological conditions are viewed as protective actions of the central nervous system (CNS) in response to perceived threats.
• A model suggests chronic pain and systemic functional neurological conditions arise from dysregulated neurological protection systems.

Purpose of the Study:

• To explore a cognitive-behavioral model for understanding chronic pain and functional neurological conditions.
• To investigate the role of biopsychosocial factors in modulating the CNS's threat detection system and descending inhibition.
• To consider the development of central sensitization within this framework.

Main Methods:

• Review and discussion of a previously established cognitive-behavioral model.
• Analysis of predisposing, precipitating, and perpetuating biopsychosocial factors.
• Examination of their impact on central nervous system (CNS) descending inhibition and threat modulation.

Main Results:

• The model successfully predicts transitions from acute to chronic states in various conditions.
• Biopsychosocial factors can significantly alter CNS modulation of threat detection.
• Central sensitization is considered a potential outcome of these alterations.

Conclusions:

• Chronic pain and functional neurological phenomena may be better understood as dysregulated neurological protection system actions.
• This perspective reframes these conditions as potentially treatable, rather than deteriorating medical issues.
• The model indicates a need for developing targeted therapeutic interventions.
