Long-Term Outcomes After Childhood Stroke

The aim of this study was to assess long-term outcomes in patients with different vascular types of childhood stroke.

Data for children with childhood stroke (aged 29 days to 18 years) were collected from the Estonian Pediatric Stroke Database. Outcomes (death, recurrent stroke, epilepsy, neurodevelopmental outcome by pediatric stroke outcome measure (PSOM)) were assessed at a minimum of two years after stroke.

Long-term outcome data were available for 44 patients with childhood stroke (including three patients who died of stroke). According to the PSOM, based on gender, age, location of stroke and epilepsy, there were no differences in outcomes, but patients with a Pediatric NIH Stroke Scale (PedNIHSS) score of ≥6 had worse outcomes compared to patients with a score of <6. Children with arterial hemorrhagic stroke (AHS) were more likely to die, suffer from epilepsy and develop problems in the cognition/behavior PSOM subscale compared to children with arterial ischemic stroke (AIS). Combined poor outcomes (epilepsy, PSOM ≥ 1, recurrent stroke, mortality) occurred in 75% (33/44) of all patients with long-term outcome data.

Combined poor outcomes occurred in 75% of the patients with childhood stroke. Patients with AHS showed higher mortality and worse long-term outcomes compared to patients with AIS in certain neurodevelopmental domains.
