Implication

Comparative sensory study reveals central hyperexcitability and altered cold pain thresholds in depressive patients, suggesting shared neurobiological mechanisms with chronic pain.

Key Points

To evaluate peripheral and central nervous system pain processing in patients with depressive disorder compared to healthy controls and patients with fibromyalgia syndrome using standardized sensory testing.
Assessed 25 depressive psychiatric inpatients (20 pain-free), 35 fibromyalgia syndrome (FMS) outpatients, and 25 healthy controls.
Performed standardized quantitative sensory testing (QST) evaluating thermal and mechanical detection thresholds, pain thresholds, pain sensitivity, and responsiveness to repetitive noxious mechanical stimuli (wind-up).
Depressive patients exhibited significantly decreased cold pain thresholds and heightened wind-up responses compared to healthy controls, displaying central hyperexcitability that exceeded levels observed in FMS.
Mechanical pain thresholds, pain sensitivity, and sensory detection thresholds remained within normal ranges across all cohorts, with no significant side-to-side differences identified in depressive disorder.
