Dr. Keerthi, I have had a seizure disorder for 23 years, controlled/free for 19 years, recently it has come back again I am trying to figure out why. In the past year I have been very stressed with a divorce, child custody, work, home hit by a tornado this list could go on, and I am experiencing partial complex seizures again, can stress cause this. Second with all of this happening I started using smokeless Tobacco can this cause a change or change in Medication I currently take 500mg of Dilantin and have done that for 20+ years.
