Hi Ladycc,
The Deja Vu you are having is known as a simple partial seizure (sz.) It can cause a person to see things that aren't really there this is because things are going on in the occipital lobe of the brain. If I may ask are you completely conscious during the entire time this is happening? If for some reason you blank out and you are not remembering things after the deja vu then you may be having an absence or complex partial sz. I've had those for 36 yrs. My advice to you is to go to a University hospital where there's an Epilepsy Center and see an Epileptologist (Dr. specializing in epilepsy) I've seen many neurologist over the yrs. and I found that they like to push the drugs but an Epileptologist is way ahead of a neurologist and will have a person on the least meds. Stay away from anything with nutra sweet or anything like it, it's been proven that nutra sweet can cause more electrical activity in the brain and cause sz. for many people I found that out the hard way when I started drinking diet soda. Also get a calendar and write down what time the sz. happens along with a description by doing this your Dr. may see a pattern as to what time of the day/night or what days of the month you are more likely to have a sz. Often women will have sz. before and after their monthly cycle and that's because the hormones are changing in the body. This is known as catamenial sz. To get more info. about epilepsy you can call The Epilepsy Foundation of America at 1-800-332-1000 they can help you out and refer you to a Dr. if you are interested. You might want to check out this website for more info. about your sz. When the main page comes up click on simple partial seizures.
