What a neurologist will do, at best, is give you an fMRI to pinpoint what part of you brain has "abormal activity". (I also have deja vous seizures, and in my case it was my right temporal lobe.) Which, as cool as that may be, is completely useless as far as fixing the problem. If your seizures aren't causing distress in your life, the neurologist will essentially just tell you to never drive or operate heavy machinery, and send you home.
If you do feel that your seizures are causing distress in your life, or might be putting you at risk of harm, then yes, you should definitely talk to a neurologist, because there are medications that may be able to help.
(I know what deja vous is like of course, I just have no idea how it fits in with any kind of seizure)
I've had, on occasion, days where I would experience 50+ déjà vus that felt like moments from some past, very vividd dream I had many years ago -- even if those moments came from a recent movie I had never seen before.
My wife started getting partial seizures much like during her second pregnancy and they culminated in a generalized tonic-clonic seizure. Her OB mis-diagnosed them as vasovagal syncopy, which is a very common phenomenon during pregnancy.
Based on getting a diagnosis it sounds like you've seen someone about this. Please, anyone out there who has similar symptoms, get it checked by a neurologist!
