Cerebral venous thrombosis (CVT) predominantly affects young to middle-aged women. Scarce data exist regarding the long-term prognosis. We examined the clinical course of patients with CVT overall and according to their age and sex. Using Danish registries, we identified all patients with a first-time primary inpatient diagnosis of CVT from 1996-2018 (N = 653; median age, 41 years; 67% women) and individuals from the general population matched for age, sex, and calendar year (N = 65 300). Patients with CVT were at an increased risk of venous thromboembolism (VTE) at other sites, ischemic stroke, major bleeding, and mortality. For both sexes, the increased risks of VTE at other sites were most prominent among younger patients (18-54 years), whereas the increased risks of ischemic stroke, major bleeding, and mortality were most prominent among older patients (≥55 years). Among young women, the 10-year risks of VTE at other sites for patients with CVT compared with members of the matched cohort were 2.2% vs 0.4% (risk difference, 1.8%; 95% confidence interval [CI], 0.0-3.6). Among older women, compared with members of the matched cohort, the 10-year risks were 12.8% vs 3.1% (risk difference, 9.7%; 95% CI, 1.6-17.9) for ischemic stroke, 11.1% vs 4.6% (risk difference, 6.5%; 95% CI, -1.0 to 14.1) for major bleeding, and 43.1% vs 26.7% (risk difference, 16.4%; 95% CI, 3.7-29.1) for all-cause mortality. The risk of myocardial infarction was not elevated. Clinicians should be aware of the importance of age and sex heterogeneity in the prognosis of CVT.
