RESUMEN
BACKGROUND: New-onset headache after stroke is common among adult stroke survivors. However, pediatric data are limited. The primary aim of this study was to investigate the prevalence of new-headache after pediatric ischemic stroke. Secondary outcomes were to describe the characteristics of patients experiencing poststroke headache and the association between poststroke headache and stroke recurrence. METHODS: We conducted a single-center retrospective study on children aged 30 days to 18 years with a confirmed radiographic diagnosis of arterial ischemic stroke (AIS) from January 1, 2008, to December 31, 2016. Patients were identified from an internal database, with additional data abstracted from the electronic medical record. Poststroke headache (occurring >30 days after stroke) was identified through electronic searches of the medical record and confirmed by chart review. RESULTS: Of 115 patients with confirmed AIS, 41 (36%) experienced poststroke headache, with headache developing a median of 6 months after stroke. Fifty-one percent of patients with poststroke headache presented to the emergency department for headache evaluation; 81% of the patients had an inpatient admission for headache. Older age at stroke (odds ratio [OR] 21.5; p = 0.0001) and arteriopathy (OR 8.65; p = 0.0029) were associated with development of poststroke headache in a multivariable analysis. Seventeen patients (15%) had a recurrent stroke during the study period. Poststroke headache was associated with greater risk for stroke recurrence (p = 0.049). CONCLUSIONS: Remote poststroke headache is a common morbidity among pediatric stroke survivors, particularly in older children. Headaches may increase health care utilization, including neuroimaging and hospital admissions. We identified a possible association between poststroke headache and stroke recurrence.
