Thank you for posting your query.
It is unfortunate that the scar of your old head injury
has led to epilepsy
It is possible for the scar to remain asymptomatic for several years, and become epileptogenic only after that.
It is difficult to pinpoint the exact reason for a sort of "quiet" scar in the brain for several years, to covert to seizure-producing scar.
However, there is no need to worry about that. If you take good anti-epileptic medications on a regular basis, you would remain seizure-free.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
