To determine the unique characteristics of cluster seizures, investigators looked at 92 subjects, 83% of whom had at least one seizure cluster. They found that seizures occurring within a cluster were significantly shorter than the last seizure that occurred in the cluster. They also discovered that the terminal seizure in a cluster is similar to duration in isolated seizures that are not part of a cluster. Finally, the researchers found that cluster seizures are more likely to occur in the frontal and temporal lobes.
