Sex-related differences in symptom presentation of patients with aneurysmal subarachnoid hemorrhage.

In patients with myocardial infarction, atypical symptoms at onset have been demonstrated in women. We aimed to investigate the presence of sex-related differences in symptom presentation in patients with aneurysmal subarachnoid hemorrhage (aSAH) to enable earlier diagnosis and treatment. We assessed symptoms on admission to hospital in 343 patients with aSAH in this retrospective single-center cohort-study.
