Your neurologist will recommend trials of a number of medications (AED's or Anti-Epileptic Drugs) to find one or a mix that prevents the seizures without causing too many side effects. It is worth taking these. Once you are seizure free for 6 months (which also helps the brain heal, decreasing the risk of future seizures) you can ask your doctor if it is reasonable to stop the medication(s).
Avoid caffeine. It can trigger seizures.
Take a good multi-nutrient supplement. There are numerous vitamins, minerals and other nutrients that have been shown to be helpful in people with seizures. These include vitamins B1, B3, B6, folate, vitamins D & E, magnesium (a major benefit), copper (no more than 1/2 mg/day), selenium, zinc, biotin, choline, glutamine and taurine.
Take adrenal nutrients. Drops in blood sugar can trigger seizures as well, so getting adrenal support, avoiding sweets, and having frequent small meals may help (give it a 1-2 month trial).
Check for allergies. Food allergies can be a potent trigger for seizures. An excellent treatment for determining and eliminating allergies is an acupressure (no needles needed) technique called "NAET." Also, find out how to do a "Multiple Food Elimination Diet" to test for them - most blood tests are horribly unreliable.
Avoid NutraSweet and MSG. If seizures occur frequently, the elimination diet may help you identify food triggers. If rare and the seizures persist despite the treatments above, try the NAET treatments. Also stop NutraSweet (aspartame) and MSG as some people have had their seizures (and other symptoms) resolve by stopping these chemicals. Substitute Stevia as a sweetener instead.
