Objective: Previous studies have shown the effectiveness of manual-based treatment for psychogenic nonepileptic seizures (PNES), but access to mental health care still remains a problem, especially for patients living in areas without medical professionals who treat conversion disorder. Thus, we evaluated patients treated with cognitive behavioral therapy-informed psychotherapy for seizures with clinical video telehealth (CVT). We evaluated neuropsychiatric and seizure treatment outcomes in veterans diagnosed with PNES seen remotely via telehealth. We hypothesized that seizures and comorbidities will improve with treatment.
Methods: This was a single-arm, prospective, observational, cohort, consecutive outpatient study. Patients with video-electroencephalography-confirmed PNES (n = 32) documented their seizure counts daily and comorbid symptoms prospectively over the course of treatment. Treatment was provided using a 12-session manual-based psychotherapy treatment given once per week, via CVT with a clinician at the Providence Veterans Affairs Medical Center.
Results: The primary outcome, seizure reduction, was 46% (P = .0001) per month over the course of treatment. Patients also showed significant improvements in global functioning (Global Assessment of Functioning, P = < .0001), quality of life (Quality of Life in Epilepsy Inventory-31, P = .0088), and health status scales (Short Form 36 Health Survey, P < .05), and reductions in both depression (Beck Depression Inventory-II, P = .0028) and anxiety (Beck Anxiety Inventory, P = .0013) scores.
Significance: Patients with PNES treated remotely with manual-based seizure therapy decreased seizure frequency and comorbid symptoms and improved functioning using telehealth. These results suggest that psychotherapy via telehealth for PNES is a viable option for patients across the nation, eliminating one of the many barriers of access to mental health care.
