  • Subject is taking currently approved AED medication(s) (but is not on valproate or divalproex sodium).
  • Subject has seizures that are distinct, stereotypical events that can be reliably counted, in the opinion of the Investigator, by the subject or caregiver.

  • Subject understands study procedures and has voluntarily provided signed, informed consent in accordance with institutional and local regulatory requirements.
  • Needs be literate in English or native language of the country of the study enrollment to complete neuropsychological testing.
  • Subject can be reasonably expected to maintain a seizure diary alone or with the assistance of a competent individual.
  • Women of childbearing potential must be using a medically accepted method of contraception and have a negative qualitative β-human chorionic growth hormone (β-HCG) pregnancy test result from a urine or blood sample collected per SOE.

You may not qualify if:

  • \. Subject has any significant neurologic disease other than epilepsy. 2. Subject has had status epilepticus refractory to benzodiazepines and phenytoin in the past year 3. Subject is currently taking oral valproic acid or sodium divalproex. 4. Subject has known allergy to valproic acid, divalproex sodium, Epilim, or Depacon.
  • \. Subject has unstable depression or any major psychiatric disorder including psychosis, major depression, bipolar disorder that in the opinion of the Investigator would put the subject at risk as a participant in the study.
  • \. Subject has history or evidence of congestive heart failure, clinically significant peripheral edema, or anemia with a hematocrit \<30%.
  • \. Subject has current diagnosis of cancer requiring treatment. 8. Subject in the opinion of the Investigator, is not a suitable candidate for cranial surgery for any reason.
  • \. Subject has known HIV infection or known or suspected prion disease. 10. Subject has known allergies to drugs or excipients. 11. Subject is breastfeeding, pregnant, or expressed intent on becoming pregnant during the course of the study and Investigator feels pregnancy is a likely outcome during the study 12. In the opinion of the investigator, the subject has a clinically significant or unstable medical condition (including alcohol and/or drug abuse) or a progressive CNS disease that in the opinion of the Investigator would put the subject at risk as a participant in the study.
