Abstract

Introduction: Childhood acute ischemic stroke is rare but increasingly recognized, with a variety of causes including thromboembolism, arteriopathy, prothrombotic states, systemic illness, and trauma. Childhood stroke is frequently under-recognized. Prehospital stroke scales have been widely validated in adults. The Modified Los Angeles Prehospital Stroke Screen (mLAPSS) is one tool used in the prehospital setting but not validated in children. Our goal was to determine in a retrospective cohort whether children with acute stroke had a positive mLAPSS score.


Methods: We performed a retrospective case series of patients less than 18 years old with a final diagnosis of acute ischemic stroke admitted to our pediatric hospital between 2014 and 2024. Demographics, presenting symptoms, mode of hospital arrival, hospital results and interventions, and final diagnosis were recorded. We attempted to determine mLAPSS criteria from earliest patient contact available, whether prehospital or emergency department records.


Results: Seventy patients with 82 stroke episodes were evaluated during the study period. Of those with past medical history, the most common were a cardiac defect or sickle cell disease. Median time from symptom onset to presentation was one day. Half of the patients presented by private vehicle. The most common symptom was a new focal weakness, but the majority of patients had more than one symptom. Documentation of grip strength and arm drift was uncommon. Only one patient had clear documentation of all three components of the mLAPSS. The etiology of stroke was uncertain in 27%, hypercoagulable in 23%, moyamoya or sickle cell disease in 23%, systemic disease in 15%, and cardiac disease in 12%.


Conclusion: While focal weakness, headache, and seizures were routinely documented in children with a final diagnosis of AIS, specific criteria of the mLAPSS, especially arm drift and grip strength, were rarely documented on initial examination.
