    Abstract:
    Traumatic brain injury is a major risk of post-traumatic epilepsy in a large number of individuals of different age groups. Lots of research has been done to elucidate the mechanism of post-traumatic epileptogenesis but age-related vulnerability to develop traumatic seizures is still unknown. Therefore, in the present study investigations were carried out to characterize the electrobehavioral seizure manifestation and associated alterations in young and old epileptic groups. FeCl(3) injection model was used to induce post-traumatic seizures as this model closely resembles human post-traumatic epilepsy. Synchronized video-EEG monitoring was performed to diagnose manifestation of seizures in young (4 months) and old (18 months) rats. Biochemical and ultrastructural studies were performed to determine the mechanism behind the altered age-related vulnerability for post-traumatic seizures. Our result shows that old rats were more vulnerable to post-traumatic epilepsy due to faster seizure spread and lower latency for generalization of electro-clinical seizure activity. The observed biochemical and microscopic alterations associated with old age positively correlate with the altered susceptibility to develop seizures in old epileptic groups.
