Bipolar and Migrains, Deja Vue, Vertigo and other epilepsy-like symptoms?

I have been diagnosed with bipolar for six years now. Symptoms have increased in severity from Type II to Type I within the first year. A few years ago, I noticed increased intense deja vue lasting much longer than most experience (5 minutes) prior to and durring hypomanic and manic episodes. More recently, I have noticed migrains accompaning hypomania. Last, I have noticed vertigo as a precurser, it happened once before prior to a very major episode, and again more recently (it's 1:30 AM and I had 5 hours of sleep last night [yes, I am in contact with my provider])

This is not accompanied with short-term amnesia, lost time, memory imparements or paralysis which seems to laymen-me, inconsistant with partial epilepsy.

However high mania has in the past included out of body experiences as well as tunnel vision, and total amnesia for periods of days to over a week, which is also inconsistant with epilepsy (each durring hospitalization).

Does anyone else know of these symptoms?
