Posttraumatic epilepsy

Recurrent seizures more than 7 days following injury.

● 2 categories: early (≤ 7 days) and late (>7 days) after head trauma

anticonvulsants (AEDs) may be used to prevent early posttraumatic seizures (PTS) in patients at high risk for seizures

● prophylactic AEDs do NOT reduce the frequency of late PTS

● discontinue AEDs after 1 week except for cases meeting specific criteria

Posttraumatic Epilepsy Epidemiology.

Posttraumatic seizures (PTS) are often divided (arbitrarily) into early (occurring within 1 week of injury) and late (thereafter) 1). There may be justification for a third category: “immediate”, i.e. within minutes to an hour or so.
