Background: study patients with PNES’ outcome after their diagnosis in the EMU. Methods: Comparative analyses were carried out on several variables before and after diagnosis: number of participants with daily PNES, number of visits to the emergency department, number of participants who took ASMs or psychotropic drugs, and employment status. Results: 61/103 patients (79% female) participated. The median age at PNES onset was 35 years. 62% were receiving ASMs and 40% psychotropic drugs. The mean stay at the EMU was five days. PNES diagnosis was explained to almost all patients (97%) by the end of their EMU stay and was well accepted by most (89%). When contacted, 46% of participants no longer had PNES; 32% mentioned that their PNES had ceased immediately upon communication of the diagnosis. Fewer patients had daily seizures after the diagnosis. Similarly, the median number of emergency department visits was significantly lower. Only 17 patients consulted their general practitioner and 20 a neurologist after a PNES attack. The use of ASMs was also significantly reduced from 70% to 33%, with only one still taking an ASM for its antiseizure properties. Conclusions: significant reductions in PNES frequency, health care utilization and ASM use.
