Prevalence and Risk Factors of Seizure Clusters in Adult Patients with Epilepsy

Highlights • Seizure cluster incidence was associated with earlier age of seizure onset, symptomatic generalized epilepsy (SGE), CNS infection, cortical dysplasia, and status epilepticus. • Seizure cluster incidence was also associated with absence of 1-year seizure freedom, and having failed 2 or m...

Description
Summary:Highlights • Seizure cluster incidence was associated with earlier age of seizure onset, symptomatic generalized epilepsy (SGE), CNS infection, cortical dysplasia, and status epilepticus. • Seizure cluster incidence was also associated with absence of 1-year seizure freedom, and having failed 2 or more AEDs. • Patients with SGE had a higher proportion of seizure clusters than patients with focal epilepsy or with idiopathic generalized epilepsy. • 56.5% of patients that experienced seizure clusters at our centers did not have a rescue medication documented in their medical records. • Increased awareness of predictors of seizure cluster and rescue medication use may lead to better care of patients with seizure clusters.
