[The brain today is yesterday's psyche].

Area of Science:

• Neuroscience
• Psychology
• Sociology

Context:

• Traditional pain models often created a false dichotomy between physical and psychological causes.
• This dualistic view led to patient stigmatization and strained healthcare provider relationships.
• Diagnostic imaging can show abnormalities unrelated to pain, and surgery is often not required.

Purpose:

• To reframe the understanding of chronic pain beyond a simple stimulus-response or nociception model.
• To highlight the complex biopsychosocial nature of pain perception.
• To introduce the significance of the International Classification of Diseases, 11th Revision (ICD-11) primary pain diagnosis.

Summary:

• Modern pain research views pain as a complex brain-constructed perception of threat, influenced by experiences and context, not solely nociception or tissue damage.
• Pain is a learned response, shaped by biological, psychological, and social factors.
• The International Classification of Diseases, 11th Revision (ICD-11) now includes a primary pain diagnosis integrating these biopsychosocial elements.

Impact:

• Shifts focus from solely physical causes to a holistic, biopsychosocial model for chronic pain.
• Reduces stigmatization associated with psychological explanations for pain.
• Expands and improves therapeutic strategies for chronic pain management through a comprehensive diagnostic framework.
