PURPOSE: Psychotherapy is recommended in patients with psychogenic nonepileptic seizures (PNES). To date, however, a limited number of studies have attempted to assess the long-term effectiveness of psychotherapy in patients with PNES. Here, we report the short and six-month follow-up seizure and psychopathological outcomes in patients with PNES who have undergone a combination of cognitive-behavioral individual and group therapy.; METHODS: In this prospective, naturalistic study, 80 patients with PNES underwent cognitive behavioral psychotherapy in an inpatient setting (mean duration: 64.5 days) and were evaluated prior to treatment (T1) and at its end (T2). Six months after treatment, 55 patients participated in the follow-up assessment (T3). Psychopathology questionnaires and PNES ratings were used at T1, T2, and T3 to determine outcomes.; RESULTS: At T2, 23% of the patients were free from PNES for ≥2 weeks. At T3, 21.8% were seizure-free for ≥1 month and 10.9% for ≥3 months. Only two patients who were free from PNES at T2 remained free from PNES until T3. Ten further patients achieved seizure freedom during the follow-up period and were free from seizures for ≥1 month at T3. Nevertheless, a subjective improvement of the seizure situation was reported by 74.1% of the patients. Patients' psychopathology scores decreased from T1 to T2 and remained stable after discharge (except for a slight increase of depression score from T2 to T3). Those patients who were PNES-free at T3 had less severe psychopathology, experienced less traumatic events, and PNES were prolonged prior to treatment than those who did not become seizure-free.; SIGNIFICANCE: Inpatient psychotherapy led to PNES freedom in a minority of patients. Pretreatment psychopathology was the key factor affecting six-month follow-up seizure outcomes. Expectations should be formed in accordance with these perspectives, i.e., seizure freedom is difficult to achieve in many patients, but psychotherapy may be useful to treat underlying psychopathology. As our results stem from a specific patient sample (i.e., patients with chronic and refractory PNES) treated in a very specific setting, the generalizability of our findings is limited.
