Patients with epilepsy are more likely to develop seizure clusters if they have symptomatic generalized epilepsy, an earlier age of onset of their seizures, or if they have status epilepticus, according to a recent review of medical records that looked at over 4000 adult outpatients with epilepsy. The investigators also found that clustering was more common in patients with symptomatic generalized epilepsy than in those with focal epilepsy or idiopathic generalized epilepsy.
