Abstract

Purpose: Inflammation plays a critical role in the development of depression after intracerebral hemorrhage (ICH), while neutrophil-to-lymphocyte ratio (NLR) has been identified as a novel comprehensive inflammatory indicator in recent years. The aim of this study was to examine the association between NLR and depression after ICH.

Patients and methods: From January 2016 to December 2018, ICH patients were prospectively enrolled. NLR was measured at admission. Depression at 3 months after ICH was diagnosed according to the Hamilton Depression Scale (HAMD).

Results: Of the 372 enrolled patients, 107 (28.8%) were diagnosed with depression at 3 months after ICH. Patients with depression had a higher NLR (6.15 vs 3.55, P < 0.001). Logistic regression analysis detected that after adjusting for major confounders, NLR remained independently associated with depression after ICH (OR = 2.25, 95% CI: 1.45-3.49, P < 0.001). Moreover, NLR acted as the optimal variable for prediction, with the optimal predictive threshold of 4.53 in ROC analysis.

Conclusion: Elevated NLR is associated with depression at 3 months after ICH, suggesting that NLR may be a significant biomarker to predict depression after ICH.
