Seizures may occur after<unk>  brain injury; these are known as<unk><unk>  seizures (PTS). However, not everyone who has<unk><unk>  seizures will continue to have<unk> , because the latter is a chronic condition. However, the terms PTS and<unk>  are used interchangeably in medical literature. Seizures due to<unk>  are differentiated from non-epileptic<unk><unk>  seizures based on their cause and timing after the trauma. A person with<unk>  suffers late seizures, those occurring more than a week after the initial trauma. Late seizures are considered to be unprovoked, while early seizures (those occurring within a week of trauma) are thought to result from direct effects of the injury. A provoked seizure is one that results from an exceptional, nonrecurring cause such as the immediate effects of trauma rather than a defect in the brain; it is not an indication of epilepsy. Thus for a diagnosis of<unk> , seizures must be unprovoked. Disagreement exists about whether to define<unk>  as the occurrence of one or more late, unprovoked seizures, or whether the condition should only be diagnosed in people with two or more. Medical sources usually consider<unk>  to be present if even one unprovoked seizure occurs, but more recently it has become accepted to restrict the definition of all types of epilepsy to include only conditions in which more than one occur. Requiring more than one seizure for a diagnosis of<unk>  is more in line with the modern definition of epilepsy, but it eliminates people for whom seizures are controlled by medication after the first seizure. As with other forms of epilepsy, seizure types in<unk>  may be partial (affecting only part of one hemisphere of the brain) or generalized (affecting both hemispheres and associated with loss of consciousness). In about a third of cases, people with<unk>  have partial seizures; these may be simple or complex. In simple partial seizures, level of consciousness is not altered, while in complex partial seizures consciousness is impaired. When generalized seizures occur, they may start out as partial seizures and then spread to become generalized.
