Just wondering about the symptoms of possibly having epilepsy may be and whether or not it is hereditary or not. Im young, only 17 and I've been experiencing dejas vu followed by nasea and dizzyness.. My father disscovered he had epilepsy later in life (early 30's) when he had a seizure while driving down a 6 lane highway in a major city in Canada. Fortunatly, after making it over the median, he narrowly escaped on-coming traffic and rolled to the shoulder of the road.
