In an effort to detect links between seizure clusters and as yet unknown clinical factors among patients with drug-resistant focal epilepsy, researchers performed a retrospective analysis of 764 patients. They found clustering in 23.6% of patients with temporal lobe epilepsy (TLE) and 16.9% of patients with extratemporal seizures. Unfortunately, they failed to detect any clinical factors associated with the clustering. However, they did notice that TLE patients fared better after surgery if they had a history of seizure clusters.
