Ages Eligible for Study:   16 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Probability Sample
Study Population
The population includes both patients whose seizures are relatively well controlled on their present conventional, enteric-coated twice-daily or three-times daily Divalproex sodium regimen.
Criteria

Inclusion Criteria:1) Patients, age 16 and above, currently taking Divalproex-DR for any seizure disorder; 2) Other AEDs are permitted concurrently, although compliance with these will not be recorded. Other medications for co-morbid disease are permitted, provided no plans for changes in medications used for the treatment of the concomitant disorder are expected.

3) Patients must demonstrate a 75% or greater compliance rate with DR via calendar during the week of familiarity with the MEMs unit. The threshold value of 75% has been chosen since research shows that people take approximately 75% of their AED(s) as prescribed (13,14), and the same numerical value is frequently used in determining whether or not to retain a patient in clinical Phase 2a-3b industry-sponsored study.

Exclusion Criteria:1) patients with a recent history of status epilepticus; 2) patients who have refractory or unstable epilepsy; 3) patients with acute illnesses requiring changes in concurrent drugs; 4) patients unwilling to change from their present DR regimen to divalproex-ER or IR-VPA.

5) Patients unwilling or unable to utilize the MEMs monitoring unit; 6) Pregnant or lactating women.
