Abstract

Abstract Background Drug resistance has been a global burden in the management of epilepsy. It is desirable if this could be predicted earlier in the course of management to give time for alternative and a more definitive mode of management, such as epilepsy surgeries. Methods We conducted a systematic review and meta-analysis to investigate the relationship between elevated age at the onset of the first seizure or cortical imaging abnormalities and the development of drug resistance in epilepsy. We performed a systematic search in PubMed, EMBASE, and SCOPUS databases for studies investigating the predictive utility of age of onset or cortical imaging abnormalities on drug resistance. Results Odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs) were extracted and analyzed by the RevMan 5.4 software. Meta-analysis was done across 12 studies involving 5315 patients. Age of onset of seizures younger than 5 years was found to be associated with the development of drug resistance (OR: 0.685, 95% CI 0.410–0.960), also cortical imaging abnormalities were found to be associated with the development of drug resistance. Conclusion Children with early onset seizures could better from neurosurgical management than pharmacological management as the early age of onset was associated with drug resistance and cortical abnormalities on neuroimaging could be an indication for neurosurgical management of epilepsies.
