Oliveira FAA, et al. - Researchers performed a narrative review focusing on headaches ascribed to ischemic strokes and transient ischemic attack. Headache ascribed to ischemic stroke had prevalence varying between 7.4% and 34% of cases, while headache ascribed to transient ischemic attack had prevalence varying from 26% to 36%. This indicates a frequent occurrence of a headache attributed to ischemic stroke, which usually has a tension-type pattern. They noted headache attributed to ischemic stroke more frequently in younger patients, migraineurs, those who have suffered a larger stroke, a posterior circulation infarction, or a cortical infarction; it was less frequently seen in lacunar infarctions. Headache attributed to ischemic stroke was most commonly a mild to moderate bilateral pain, not linked with nausea, vomiting, photophobia, or phonophobia. Usually, this headache occurs concomitantly with focal neurologic deficit and improves over time.
