This study aims to assess neuropathic pain through validated diagnostic tools in prediabetes. Methods: One hundred and seventy-two patients with prediabetes and 170 controls were included in this cross-sectional study. The Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale and Douleur Neuropathique 4 Questions (DN4) were used to evaluate neuropathic pain. The Visual Analog Scale (VAS) was used to estimate pain intensity. Results: Twenty-three (13.4%) and 12 (7%) patients with prediabetes were diagnosed with neuropathic pain using DN4 and LANSS questionnaires, respectively. Neuropathic pain rates of the patients were higher than controls with two pain scales (p < 0.001). VAS scores were higher in prediabetes group than in controls (p = 0.021). LANSS, DN4, and VAS scores were positively correlated with HbA1c level (r = 0.184, p = 0.016; r = 0.180, p = 0.018; r = 0.188, p = 0.014, respectively). LANNS and DN4 scores were higher in female patients than in males (p < 0.001). Conclusions: Neuropathic pain was increased in prediabetes by DN4 and LANNS questionnaires. An appropriate diagnosis of neuropathic pain in prediabetes may prevent patients from different pain-related clinical conditions.
