<div><p>Depression and cognitive impairment have been identified as risk factors for cerebrovascular events (CVE), and one of their potential etiological pathways is inflammatory status. This prospective study aims to investigate the association between inflammatory markers and the risk of CVE in a population of 2659 older adults, enrolled in the Progetto Veneto Anziani (Pro.V.A.), with depressive symptoms, cognitive impairment, or both conditions. For each individual, we assessed at baseline the presence of depressive symptoms (defined as a Geriatric Depression Scale ≥11), cognitive impairment (defined as a Mini-Mental State Examination <24), and serum levels of fibrinogen, white blood cells (WBC), and erythrocyte sedimentation rate (ESR). During a 4.4-year follow-up, 188 (7.1%) participants had CVE. Among the inflammatory markers, high fibrinogen values were associated with a 50% higher risk of CVE in the whole sample, and with a 4-fold higher risk in individuals with both depressive symptoms and cognitive impairment (hazard ratio = 4.04, 95% confidence interval: 1.45-11.23). Elevated WBC were associated with a 5% higher risk of CVE in the whole sample and in those with both conditions. No significant association was observed with the ESR. In conclusion, our study found that high fibrinogen levels may predict the risk of CVE in older people with concomitant depressive symptoms and cognitive impairment. Therefore, fibrinogen could be considered as an easily accessible aging biomarker, which might estimate the chronic inflammatory status and its potential detrimental effects on the most vulnerable older adults.</p></div>
