ABSTRACT

Background and Objectives: Perinatal stroke leads to significant morbidity over a child’s lifetime, including diagnosis of various neurodevelopmental disorders. Specific studies examining the prevalence of autism spectrum disorder in children with perinatal stroke are scarce. Following the clinical observation of autism spectrum disorder in a pediatric referral stroke center, we evaluated the rate of autism spectrum disorder diagnosis after perinatal ischemic stroke, including analysis by subtypes of perinatal ischemic stroke. Methods: We retrospectively examined all children diagnosed with perinatal ischemic stroke, who were ≥18 months old at the time of last follow-up at a single institution from 2008 through 2021. We classified patients as having autism spectrum disorder if they were diagnosed by a neurologist, neuropsychologist, clinical psychologist, or developmental pediatrician. Multivariable logistic regression was performed to examine the association between ischemic stroke subtype and autism spectrum disorder. Results: Among 260 children with perinatal stroke, 19 children (7.3%) also had autism spectrum disorder. Children with perinatal venous stroke had 3-fold higher odds of autism spectrum disorder compared to those with perinatal arterial ischemic stroke (adjusted odds ratio: 3.01, 95% confidence interval: 1.07-8.47). Conclusion: In our perinatal ischemic stroke population, children with venous stroke had higher odds of autism spectrum disorder compared to those with arterial ischemic stroke alone. Prospective studies are needed to further investigate the role of perinatal stroke in autism spectrum disorder development.
