II. Types

  1. Early Posttraumatic Seizure
    1. Within first 7 days of initial Head Injury
  2. Late Posttraumatic Seizure
    1. Beyond first 7 days from initial Head Injury

III. Risk Factors

  1. Glasgow Coma Scale (GCS) <10
  2. Posttraumatic Amnesia >30 minutes
  3. Skull Fracture
  4. Penetrating Head Injury
  5. Intracranial Hemorrhage
  6. Cortical Contusion
  7. Age >65 years old
  8. Chronic Alcoholism

IV. Management

  1. See Status Epilepticus
  2. Seizure Prophylaxis Indications based on above risk factors
    1. Recommended for early Posttraumatic Seizure (first 7 days) due potential impact on TBI recovery
    2. Not recommended for late Posttraumatic Seizure prophylaxis due to adverse effects
  3. Seizure Prophylaxis Agents
    1. Phenytoin
      1. Recommended by Brain Trauma Foundation
    2. Levetiracetam (Keppra)
      1. Often used in practice

V. Prognosis

  1. Posttraumatic Seizure itself is not associated with worse prognosis
  2. However, Posttraumatic Seizure does occur more commonly with severe Traumatic Brain Injury

Definition (MSH) Recurrent seizures causally related to CRANIOCEREBRAL TRAUMA. Seizure onset may be immediate but is typically delayed for several days after the injury and may not occur for up to two years. The majority of seizures have a focal onset that correlates clinically with the site of brain injury. Cerebral cortex injuries caused by a penetrating foreign object (CRANIOCEREBRAL TRAUMA, PENETRATING) are more likely than closed head injuries (HEAD INJURIES, CLOSED) to be associated with epilepsy. Concussive convulsions are nonepileptic phenomena that occur immediately after head injury and are characterized by tonic and clonic movements.
