The factor most predictive of posttraumatic seizures is a GCS of < 8; 38.7% of patients with a GCS of < 8 will develop seizures compared with 3.8% of patients with a GCS > 8. Patient age, occipital lobe injury, concomitant use of illicit drugs, and generalized brain injury have not been shown to be predictive of posttraumatic seizures.2
