Right temporoparietal junction transcranial direct current stimulation in the treatment of functional dissociative seizures: a case series.

Abstract

Functional dissociative seizures (FDSs) are clinical events that resemble epileptic seizures but are not associated with abnormal brain electrical discharges or other physiological problems. In this pilot case series, ten adults with FDSs were recruited from our psychiatry department after being referred by a neurologist who made the diagnosis of FDS based on video EEG results. Each subject received ten sessions of cathodal tDCS focused on the right temporoparietal junction. A significant decrease in weekly seizure frequency was seen in all participants between baseline (30.2 ± 70.3 events) and 1 month after tDCS treatment (0.2 ± 0.3events) (p = 0.006). Main predisposing factors were unchanged after treatment.
