The aim of this study was to assess prognosis among adult patients with nonepileptic seizures (NES) and to determine predictor variables for resolution of NES after diagnosis. Six to 9 months after receiving a video-EEG-documented diagnosis of NES, 43 adults responded by telephone interview to a detailed, structured questionnaire probing history of the episodes, psychiatric factors, socioeconomic variables, relationships, reactions to receiving the diagnosis, and potential history of litigation. At follow-up, only 18.6% were episode-free, 55.8% had improved, 16.3% reported no change, and 9.3% reported greater frequency of episodes. Patients who reported having many friends currently or having good relationships with friends as a child were significantly more likely to be episode-free. Subjects with pending litigation were significantly less likely to experience a reduction in episodes.
