Focal seizures may be seen, with features referable to the location of the injury within the brain, either acutely or long-term.

Focal to bilateral tonic-clonic seizures can occur, these may have focal features referable to the location of brain injury if this information is carefully sought.

Status epilepticus, including focal status epilepticus, can occur, especially at the time of the acute injury.

In young patients with traumatic brain injury in early life, seizures evolution may include emergence of epileptic spasms or generalized seizure types, such as atypical absence, atonic and tonic seizures. This evolution may be associated with cognitive and neurodevelopmental regression. If these seizure types are seen, and if seizure control is not achieved with medication, epilepsy surgery may be considered if the region of traumatic brain injury causing seizures is localized.

CAUTION seizures in neonates and young infants with traumatic brain injury may be subtle clinically, and may require EEG surveillance for detection or confirmation.
