In brief: Variable

Post-traumatic seizures may occur early following a brain injury but may also persist for years.
Persistent recurrent seizures following brain injury are sometimes referred to as "late post-traumatic epilepsy".

In brief: Depends

A person can have a seizure in the immediate aftermath of even a slight head trauma, that never recurs.
If that head injury caused tissue damage inside the brain, they may have a focus that can trigger seizures for the rest of their life.

In brief: May be permanent

Seizures may have been "triggered" by the head injury.
In that case, you were "on the edge" of a seizure disorder before the injury.
