Abstract

Background: Determining the various consequences of lichen planopilaris (LPP) is essential for improving patient care strategies. The aim of this study was to evaluate sleep quality in patients with LPP. Methods: In this case-control study, 58 patients with LPP were enrolled, along with an equal number of age-and sex-matched healthy controls. The Pittsburgh Sleep Quality Index (PSQI) was utilized to evaluate sleep disturbances in all participants. Additionally, the Dermatology Life Quality Index (DLQI) was assessed. Results: The mean PSQI score was 11.2 ± 4.8 for the case group and 4.4 ± 2.7 for the control group, indicating a statistically significant difference (P = 0.001). Additionally, the mean quality of life score was 11.6 ± 7.2 for the case group and 3.1 ± 3.04 for the control group, which also demonstrated a statistically significant difference (P = 0.001). Conclusion: This study demonstrated that patients with LPP experienced decreased sleep quality and a lower quality of life compared to the healthy population. We recommend screening for sleep disturbances in patients with LPP, as these disturbances may serve as prodromal symptoms of mood disorders. © 2025 Elsevier B.V., All rights reserved.
