As growing research suggests noninvasive brain stimulation techniques have the potential to adjunct current treatments or treat Seizure-Type Functional Neurologic Disorder (FND-seiz), also known as Psychogenic Non-Epileptic Seizures (PNES), we aim to evaluate whether a form of accelerated intermittent theta burst transcranial magnetic stimulation (a-iTBS-rTMS), is a practical and well-tolerated treatment for people with this disorder. Transcranial Magnetic Stimulation or TMS uses magnetic pulses to stimulate a part of the brain involved in mood and thinking, the left dorsolateral prefrontal cortex, which has established benefits in disorders known to coincide in patients with FND-seiz, such as depression.
As an open-label, early feasibility study, enrolled participants will receive 6 to 10 treatment sessions each day over 3 to 5 days, with the goal of completing 30 total sessions. This approach was selected because similar protocols have already been shown to be safe and effective in other conditions, and the shortened treatment schedule in comparison to other protocols may make participation easier for people living with FND-seiz. The main goal of the study is to see how many participants can safely and comfortably complete at least 20 of the 30 TMS sessions.
The researchers will also evaluate changes in seizure frequency, quality of life, mood, post-traumatic stress symptoms, physical health, social functioning, and overall satisfaction with treatment. These outcomes will be measured before treatment and again four weeks afterward. The researchers also aim to explore whether people with overlapping conditions, such as depression or PTSD, respond differently to the treatment. Finally, given the overlap between epilepsy and FND-seiz, not all TMS providers are comfortable treating patients with FND-seiz when TMS is indicated for other conditions, thus the researchers aim to outline a protocol to ensure safety and increase TMS access for FND-seiz patients.
