Abstract
BACKGROUND: There are few population-based data regarding gender differences in signs and symptoms of acute ischemic stroke, and previously reported data have been inconsistent and conflicting. OBJECTIVE: The goal of this study was to address the gender differences of the presenting signs and symptoms of acute ischemic stroke in a population-based study. METHODS: All patients with first ischemic stroke occurring between 1985 and 1989 were identified; subjects were residents of Rochester, Minnesota. Signs and symptoms were collected via review of comprehensive medical records. Differences were identified using the Pearson χ(2) test. RESULTS: A total of 449 cases of first ischemic stroke were identified; 268 (60%) were women. Symptoms at ischemic stroke presentation differed between men and women. Women more commonly presented with generalized weakness (P = 0.005) and mental status change (P = 0.0001). Men more commonly presented with paresthesia (P = 0.003), ataxia (P = 0.006), and double vision (P = 0.005). Signs at ischemic stroke presentation differed between men and women. Men more commonly presented with nystagmus (P = 0.002) on examination. Significant trends were that women more commonly presented with fatigue (P = 0.02), disorientation (P = 0.04), and fever (P = 0.02), whereas men more commonly presented with sensory abnormalities (P = 0.02). CONCLUSIONS: There were gender differences in signs and symptoms at presentation of ischemic stroke in these study patients. In addition to selected focal symptoms, women more commonly presented with diffuse symptoms of generalized weakness, fatigue, disorientation, and mental status change.
