Patients with chronic pain lack somatic markers during decision-making

What is it about?

Patients with chronic pain have reduced decision-making ability, measured with the Iowa Gambling Task (IGT). By measuring skin conductance during IGT, this study found that a group of chronic pain patients lacked skin conductance events ("somatic markers") before disadvantageous decisions.

Why is it important?

This is the first study to shed light on potential mechanisms for decision-making impairments in patients with chronic pain. A better understanding of how chronic pain affects decision-making could lead to a better understanding of both how chronic pain affects the brain, and of how decision-making processes happen in the brain.
