The prognosis for<unk>  due to trauma is worse than that for<unk>  of undetermined cause. People with<unk>  are thought to have shorter life expectancies than people with brain injury who do not suffer from seizures. Compared to people with similar structural brain injuries but without<unk> , people with<unk>  take longer to recover from the injury, have more cognitive and motor problems, and perform worse at everyday tasks. This finding may suggest that<unk>  is an indicator of a more severe brain injury, rather than a complication that itself worsens outcome.<unk>  has also been found to be associated with worse social and functional outcomes but not to worsen patients' rehabilitation or ability to return to work. However, people with<unk>  may have trouble finding employment if they admit to having seizures, especially if their work involves operating heavy machinery. The period of time between an injury and development of<unk>  varies, and it is not uncommon for an injury to be followed by a latent period with no recurrent seizures. The longer a person goes without developing seizures, the lower the chances are that<unk>  will develop. At least 80–90% of people with<unk>  have their first seizure within two years of the TBI. People with no seizures within three years of the injury have only a 5% chance of developing<unk> . However, one study found that head trauma survivors are at an increased risk for<unk>  as many as 10 years after moderate TBI and over 20 years after severe TBI. Since head trauma is fairly common and<unk>  can occur late after the injury, it can be difficult to determine whether a case of<unk>  resulted from head trauma in the past or whether the trauma was incidental. The question of how long a person with<unk>  remains at higher risk for seizures than the general population is controversial. About half of<unk>  cases go into remission, but cases that occur later may have a smaller chance of doing so.
