Poststroke headache is a common morbidity among pediatric stroke survivors as a new study finds that there is a possible association between poststroke headache and stroke recurrence. The findings of the study are published in the journal Neurology Clinical Practice.

Headache developed in over a third of participating children, on average, six months after the stroke. Fifteen percent of patients suffered another stroke, typically in the first six to 12 months after the initial stroke. In the study, most children who experienced headache during stroke recurrence also had other associated neurologic symptoms, mostly weakness of one side of the body (hemiparesis) or facial asymmetry and brain malfunction (encephalopathy).

"In our study, post-stroke headache was more common in patients who experienced another stroke, which suggests that it might be a risk factor for stroke recurrence," says co-lead author Jonathan Kurz, MD, PhD, pediatric neurologist in the Ruth D. & Ken M. Davee Pediatric Neurocritical Care Program at Ann & Robert H. Lurie Children's Hospital of Chicago, and Instructor of Pediatrics at Northwestern University Feinberg School of Medicine.

"More research is needed to test this hypothesis, and it remains unclear if headache treatment would lower the risk for stroke recurrence. Children with a post-stroke headache might need closer observation or different strategies to prevent another stroke. This requires more study."

The risk of stroke from birth through age 19 years is about five per 100,000 children, according to the Children's Hemiplegia and Stroke Association (CHASA). In children, the risk of stroke is highest in the first year of life, especially during the perinatal period (a few weeks before and after birth).

The study included 115 children, aged 30 days to 18 years, who had survived a stroke. Thirty-six percent of these children experienced a headache that occurred more than 30 days after their stroke. Children with post-stroke headache tended to be survivors of a stroke caused by artery disease (arteriopathy). Of these children, over half had headache severe enough to go to the emergency department, and 81 percent were admitted to the hospital for headache.

"Earlier recognition post-stroke headache in children may improve the care, recovery, and quality of life in pediatric stroke survivors," says Dr. Kurz. "Further research will help us better understand the causes of post-stroke headache and its association with stroke recurrence."
