About

The purpose of this study is to design and test the safety and feasibility of virtual reality technologies and experiences of egocentric avatar embodiment in the application of physical and cognitive behavior therapy in functional neurological symptom/conversion disorder. Investigators hypothesize that patients will safely use and accept this modality of treatment and will show evidence of a decrease in symptom frequency.

Full description

This is a treatment development trial, participants randomly assigned to active treatment will be enrolled in embodied Virtual Reality therapy. The therapy will be based on principals of exposure and behavioral shaping therapies and mirror visual feedback therapy. The therapy will be delivered over 8 sessions and modified as indicated by clinical feedback. A fixed protocol will be developed with exact methods to be used to be determined. After a fixed protocol has been established, a treatment manual will be created to use in further controlled trials.

If diagnosis of seizure type then video EEG with diagnosis confirmed by board-certified neurologist with subspecialty training in epilepsy and clinical neurophysiology using the criteria of the International Classification of the Epilepsies is required. If diagnosis of motor type, documented and clinically established levels of diagnostic certainty (Williams,1995) confirmed by 2 neurologists is required. Participants must have at least one symptom per month in the month prior to enrollment Fluency in English spoken language
