Psychogenic non epileptic seizures: 33 Patients observed at the Epilepsy Center of the University of Messina

33 patients affected by psychogenic non epileptic seizures (PNES) were included in the study. They were differentiated in two groups: group 1 (19 patients with pure PNES); group 2 (14 patients with PNES and epileptic seizures). Significant differences between the two groups were: longer diagnostic delay (5,3 years) and poorer outcome (only 1 patient seizure-free) in group 2 when compared to group 1 (diagnostic delay 2.9 years, 50% of patients seizure-free at the last follow-up).
