ABSTRACT
BACKGROUND: We report the observation of a 47-year-old woman with functional neurological disorder (tetraparesis, mixed tremors and non-epileptic seizures) treated with a protocol of augmented psychotherapy in combination with repeated transcranial magnetic stimulation (rTMS). INTERVENTION: We carried out a biofeedback psychotherapy protocol with rTMS (twenty sessions, two sessions per day for ten days; 1Hz, 150% of the motor threshold, twenty minute sessions, 300 pulses per session) in which the patient visualized the motor activity of her upper limbs during stimulation of the primary motor area (PMA). The evolution of neurological symptoms was assessed using the Medical Research Council Scale for Muscle Strength (MRC). RESULTS: Symptoms were improved between the 4th and 6th days of treatment (8th and 12th sessions) with first a relief of paresis, then a secondary cascade improvement of other functional symptoms. At two months the patient no longer presented any functional neurological symptoms. DISCUSSION & CONCLUSION: We propose several hypotheses concerning the effectiveness of this type of biofeedback protocol using rTMS. We also suggest that this type of protocol should be systematically associated with psychotherapeutic support on biographical elements for holistic management. This observation underlines the interest of potentiating cognitive-behavioral therapies using the principle of operant conditioning with the aid of brain stimulation in functional neurological disorders, and motivates the realization of future studies.
