A Novel Integrative Psychotherapy for Psychogenic Nonepileptic Seizures Based on the Biopsychosocial Model: A Retrospective Pilot Outcome Study

Background: Psychogenic nonepileptic seizures (PNES) represent one of the most sizable treatment challenges in neuropsychiatry. Although the underlying mechanism is far from being understood, several interventions have been suggested. However, patients with comorbid psychiatric diagnoses and epilepsy are excluded from most intervention studies. Objective: To To present a within-group posttreatment vs pretreatment study representing the retrospective clinical results of an integrative psychotherapy model. Methods: We present the clinical results of 22 patients with PNES diagnosed in an epilepsy center and treated in our neuropsychiatry clinic using an integrative rehabilitative psychotherapy. Therapy included presenting the diagnosis, psychoeducation, seizure reduction behavioral techniques, and coping with past and present stressors. Insomuch as integrative biopsychosocial psychotherapy is based on an individualized treatment protocol for each patient, treatment was individualized and case specific. Results: By the end of treatment, 36% of patients had become seizure free and a further 54% achieved a major seizure reduction (reduction of more than 70%). Seventy-two percent of patients kept at least 70% seizure reduction at follow-up. Global Assessment of Functioning scores improved from a mean of 43.09 to a mean of 72.81 at the end of treatment and 69.72 at follow-up. In addition, we present 3 case descriptions that emphasize the individualized nature of psychotherapeutic decisions. Conclusions: Our results support the feasibility and effectiveness of biopsychosocial based integrative psychotherapy for PNES and set principles for future treatment and prospective clinical trials in the field of individualized psychotherapy.
