The impact of prophylactic treatment on post-traumatic epilepsy after severe traumatic brain injury

Abstract

AIM: To assess the incidence of late post-traumatic epilepsy (PTE) in patients with very severe traumatic brain injury (TBI) who either received or did not receive anti-epileptic prophylactic treatment. METHODS: Two populations were studied: 55 patients retrospectively and 82 subjects prospectively. RESULTS: Ten patients (18%) in the first population showed late PTE. Although the incidence was lower in patients who did not receive prophylactic treatment, the difference between the treated and the non-treated group was not statistically significant. Sixty-nine patients in the second group (84%) had prophylactic treatment. Twenty-seven patients (39%) suffered from late PTE during the 2-year follow-up period and 17 of them (63%) showed EEG epileptic abnormalities. No patient who did not receive preventive therapy suffered from late PTE during the observation period. CONCLUSIONS: Due to the negative cognitive effects of anti-epileptic drugs, the preliminary results are of considerable interest for the rehabilitation of patients with very severe TBI.
