OBJECTIVE: To assess the incidence, characteristics, and risk factors for developing persistent headache attributed to past ischemic stroke.
BACKGROUND: Although the most recent International Classification of Headache Disorders has recognized the existence of persistent headache attributed to past ischemic stroke, there has been limited research in this area.
METHODS: This was a prospective cohort study. We initially assessed patients hospitalized with ischemic stroke admitted within 72 h of symptom onset. All patients underwent diffusion-weighted magnetic resonance imaging. These patients were re-interviewed by telephone 1 year after the stroke. Semi-structured questionnaires, the National Institutes of Health Stroke Scale (NIHSS), and six-item Headache Impact Test were used.
RESULTS: A total of 119 participants answered the interview conducted 1 year after the stroke. The mean (standard deviation) age was 64 (13.1) years, 82/119 (68.9%) were female, and the median (interquartile range) NIHSS score was 2 (1.0-4.0). The incidence rate of persistent headache attributed to past ischemic stroke was 12/119 (10.1%; 95% confidence interval [CI] 5.3-17.0%). The most frequent pattern presented was a migraine-like pattern in seven of the 12 (58.3%) patients, which had a substantial/severe impact on five of the 12 (41.7%). For most patients this headache continued, although it began to improve. Previous migraine (odds ratio 7.1, 95% CI 1.06-50.0; p = 0.043) and headache intensity in the acute phase of stroke (odds ratio 1.75, 95% CI 1.13-2.7; p = 0.012) were associated with the occurrence of persistent headache attributed to past ischemic stroke.
CONCLUSION: Persistent headache attributed to past ischemic stroke is a frequent complication after stroke. It often has a significant impact on patients' lives and presents a migraine-like pattern as its most frequent phenotype.
