EEG Features in Post-Traumatic Syndrome

Abstract

Standard and 24-hour ambulatory EEG recordings were performed on 54 patients with post-traumatic syndrome that developed after minor closed head trauma or whiplash neck injuries. Paroxysmal activity occurred in 9.2% of patients, either specific or non-specific. While being monitored, 24 patients experienced symptoms typical of this disorder without concurrent EEG abnormalities. No patient exhibited abnormalities in the 24-hour ambulatory recording alone. The symptoms of post-traumatic syndrome were not epileptogenic and the overall incidence of EEG abnormalities in this disorder was low, contradicting some previous reports.
