Figure 3. Seizure Frequency through Time.

Figure 3.

Cumulative percentages of seizure activity (Y-axis) is shown in years following epilepsy diagnosis along the X-axis. The cases that have been seizure free for 12 months, with or without ASMs, are designated “No Sz.” The orange bar shows cases that have on-going seizures (“Active Sz”) but have not reached the criteria for being considered drug-resistant. The remainder of cases are those with drug-resistant epilepsy (“DRE”), meaning ongoing seizures with 2 or more ASMs failed for either side effects of lack of efficacy. By 3 years, almost 90% of cases have either achieved excellent seizure control or become intractable.
