Is it possible to develop seizures from a traumatic brain injury that happened 39 years ago?

My husband had a nail go in his brain when he was a year old, and a couple weeks ago had a seizure. The doctors are wondering if it is possible that the trauma from the brain injury caused him to have this seizure. They said that the CT Scan showed compromised brain matter around the area that the nail went in. They could actually see the spot where the nail would have been. Crazy as I would've thought that it would've healed.

This entire thing is nuts as he now can't drive, but drives for a living, so I have had to start driving again so that he doesn't lose his job... we are a perfect pair!!
