Abstract
ObjectiveTo determine epilepsy and neurodevelopmental outcomes beyond 2 y of age and their putative prognostic factors in children with West syndrome (WS).MethodsThis cross-sectional study was initiated after approval from Institutional Ethics Committee. A follow-up cohort of 114 children (aged ≥ 2 y) diagnosed and treated for WS at the authors' center were assessed in-person for epilepsy and neurodevelopmental outcomes using Vineland Social Maturity Scale - Malin’s adaptation for Indian children. Subsequently, age at onset, lead-time-to-treatment, etiology, and response to any of the standard therapies were analyzed as possible predictors of these outcomes.ResultsOf 114 children (mean age: 55 ± 32 mo, 91 boys), structural etiology was the predominant underlying etiology (79.8%) for WS. At 2 y of age, 64% had ongoing seizures. At the last follow-up, 76% had social quotient < 55, and 39% had cerebral palsy (spastic quadriparesis in 21%). An underlying structural etiology was associated with ongoing seizures [OR (95% CI) 3.5 (1.4–9); p = 0.008] at 2 y of age and poor developmental outcomes [OR (95% CI): 3.3 (1.3–8.9); p = 0.016]. Complete cessation of spasms with the standard therapy was significantly associated with better seizure control [OR (95% CI): 5.4 (2.3–13); p < 0.001] and neurodevelopmental outcome [OR (95% CI): 5.2 (1.8–14.9); p < 0.001].ConclusionThe majority of children with WS have a poor neurodevelopmental outcome and epilepsy control on follow-up. The underlying etiology and response to initial standard therapy for epileptic spasms have a prognostic role in predicting the neurological outcome in these patients on follow-up.
