Abstract
The association between prolonged febrile seizure and long-term neurological sequelae in otherwise healthy children remains unclear. We conducted a retrospective cohort study using a Japanese nationwide medical database. In the cohort of 38,465 children with febrile seizures, 610 and 31,157 were classified into the prolonged and non-prolonged groups, respectively. Within a median of 2.70 years of follow-up, the risk of subsequent epilepsy was significantly higher in the prolonged febrile seizure group (hazard ratio, 3.99; 95% confidence interval, 2.40-6.64). The risk of neurodevelopmental disorders was similar between the two groups (hazard ratio, 1.39; 95% confidence interval, 1.00-1.79). ANN NEUROL 2025.
期刊介绍：
Annals of Neurology publishes original articles with potential for high impact in understanding the pathogenesis, clinical and laboratory features, diagnosis, treatment, outcomes and science underlying diseases of the human nervous system. Articles should ideally be of broad interest to the academic neurological community rather than solely to subspecialists in a particular field. Studies involving experimental model system, including those in cell and organ cultures and animals, of direct translational relevance to the understanding of neurological disease are also encouraged.
