No, there's no likely relationship. Your brain electrical storm was all self generated. Only time will tell if it was transient or has an underlying physiological basis.
A lot of times, these types of events are a once-only occurrence and the brain will auto correct whatever caused it.
Just keep the faith and understand that if all current scans are good, then it's nothing scary that can't be addressed reasonably if it were to ever happen again.
My niece had incidents like this and after a few times over several years, it was nailed down and is now well managed without further occurrence. Turned out to be the result of a fall she had as a child that caused a concussion and created an electrical tangle in the scar tissue that began randomly firing 20 years later. One pill per day at a low dose and no more issue. This is why I said mention the sudden memory restoration from the concussion you had. It may be something similar.
