Sex Differences in Clinical Presentation of Women and Men Evaluated at a Comprehensive Stroke Center for Suspected Stroke.

Abstract

Introduction: Understanding sex differences in the clinical presentation of patients with suspected stroke is important to reduce sex-related disparities and improve care. We aimed to characterize presenting symptoms in women and men with suspected stroke evaluated at our comprehensive stroke center.

Methods: This was a retrospective analysis of consecutive patients with suspected stroke treated at the University Hospital Essen between January 2017 and December 2021. Patient characteristics, signs and symptoms as well as final diagnoses in women and men were compared. Logistic regression analysis was performed to assess the association of individual symptoms with a diagnosis of cerebrovascular disease.

Results: We included 6069 patients in our analysis. Cerebrovascular disease was diagnosed in 85.2% (2576/3022) of women and 88.0% (2681/3047) of men (p = 0.002). Aphasia (31.4% vs. 27.7%, p = 0.002), neglect (15.5% vs. 12.8%, p = 0.003), gaze deviation (21.0% vs. 18.8%, p = 0.034), as well as nonfocal symptoms including impairments in consciousness (17.0% vs 14.6%, p = 0.012), orientation (42.5 vs. 36.4%, p < 0.001) and completion of tasks (31.2% vs. 26.0%, p < 0.001) were more common among women. Limb ataxia (8.1% vs. 11.2%, p < 0.001) and dysarthria (44.0% vs. 46.8%, p = 0.030) were less frequent in women. Neglect and gaze deviation were independent positive predictors of cerebrovascular disease in women but not in men.

Conclusion: Although clinical presentation was similar in both sexes, cortical and nonfocal symptoms were more common among women with suspected stroke. Awareness of sex differences and acknowledgement of the full clinical picture are important to ensure optimal management for women and men with suspected stroke. Our findings might serve as a target for educational programs in order to improve preclinical stroke detection in patients with predominantly nonfocal or subtle symptoms.
