Persistent Headache Attributed to Past Stroke (PHAPS) is a controversial entity, recently included in the new ICHD-3 classification despite being described only in retrospective studies. The aim of this study was to determine the incidence and characteristics of PHAPS in patients admitted with acute stroke. We selected all patients with Headache Associated with Acute Stroke (HAAS) from a prospective, single-centre registry of patients with acute stroke admitted to a Neurology ward between November 2018 and December 2019. We analysed demographic, clinical and neuroimaging data. We assessed the follow-up with a phone call questionnaire at 6-12 months. Among 121 patients with acute stroke, only 29 patients (24, 0%) had HAAS. From these, 6 were lost to follow-up. Twenty-three patients answered the 6 to 12- month follow-up questionnaire and were included in this study. Median age was 53 years (IIQ 38-78) and there was no gender predominance. Of the 10 patients (43, 5%) that had persistent headache, 8 clearly suffered from Previous Chronic Headaches (PCH), however, they all mentioned a different kind of headache. Only 1 patient did not have other reasons for a secondary headache.
