<unk>  is associated with a generally good prognosis. It is unknown exactly how long after a TBI a person is at higher risk for<unk> s than the rest of the population, but estimates have suggested lengths of 10 to over 15 years. For most people with TBI,<unk> s do not occur after three months, and only 20–25% of people who suffer TBI have<unk>  more than two years after the injury. However, moderate and severe TBI still confer a high risk for<unk>  for up to five years after the injury. Studies have reported that 25–40% of<unk>  patients go into remission; later studies conducted after the development of more effective<unk>  medications reported higher overall remission rates. In one quarter of people with<unk> s from a head trauma, medication controls them well. However, a subset of patients have<unk> s despite aggressive antiepileptic drug therapy. The likelihood that<unk>  will go into remission is lower for people who have frequent<unk> s in the first year after injury. Risk of developing PTE It is not known whether<unk>  increase the likelihood of developing PTE. Early<unk> , while not necessarily epileptic in nature, are associated with a higher risk of PTE. However,<unk>  do not indicate that development of epilepsy is certain to occur, and it is difficult to isolate<unk>  from severity of injury as a factor in PTE development. About 3% of patients with no early<unk> s develop late PTE; this number is 25% in those who do have early<unk> , and the distinction is greater if other risk factors for developing PTE are excluded.<unk> s that occur immediately after an insult are commonly believed not to confer an increased risk of recurring<unk> s, but evidence from at least one study has suggested that both immediate and early<unk> s may be risk factors for late<unk> s. Early<unk> s may be less of a predictor for PTE in children; while as many as a third of adults with early<unk> s develop PTE, the portion of children with early<unk>  who have late<unk> s is less than one fifth in children and may be as low as one tenth. The incidence of late<unk> s is about half that in adults with comparable injuries.
