Dias MC, Martins T, Basílio G, et al. - Researchers performed a prospective observational cohort study including 102 acute ischemic stroke patients admitted to a Stroke Unit with the aim to delineate the features of headache and the predictors of headache at the chronic stage after ischemic stroke. At the acute and the chronic stage (12 months after stroke), interviews were conducted among the patients. Eighty-nine patients completed the follow-up; of these, 45 patients (51%) reported headache at the chronic stage. Most of the patients reported sporadic, mild, pressure-like headache, with a duration of minutes to hours; in 51% (n = 23/45) it had characteristics of tension-type headache. Among ischemic stroke survivors, women and patients with a prestroke headache more frequently experienced a headache at the chronic stage. Most frequently, this headache had different characteristics from the prestroke headache and only rarely a new-onset headache starting at the acute stage and persisting at the chronic stage.
