observational, non-interventional study in 120 patients with drug-resistant partial epilepsy, comprising two phases: a 3-month retrospective and a 6-month prospective. As control group, 120 patients with controlled partial epilepsy will be enrolled. The objective of the study is to describe the burden of illness in this epileptic population both in terms of costs and of quality of life. Costs and quality of life will be also compared between the two populations.
