Epidemiology
Studies have found that the incidence of PTE ranges between 1.9 to more than 30% of TBI sufferers, varying by severity of injury and by the amount of time after TBI for which the studies followed subjects.
Brain trauma is one of the strongest predisposing factors for epilepsy development, and is an especially important factor in young adults. Young adults, who are at the highest risk for head injury, also have the highest rate of PTE, which is the largest cause of new-onset epilepsy cases in young people. Children have a lower risk for developing epilepsy; 10% of children with severe TBI and 16–20% of similarly injured adults develop PTE. Being older than 65 is also a predictive factor in the development of epilepsy after brain trauma. One study found PTE to be more common in male TBI survivors than in females.
