Brief Summary

Functional neurological disorder (FND) is a condition that causes significant suffering and disability. It is defined by the presence of neurological symptoms that interfere with an individual's functioning and are not consistent with any known anatomical lesion but that causes significant functional impairment. The investigators are particularly interested in motor symptoms (abnormal movements or motor deficits). Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive and acceptable treatment that has proven effective in certain chronic pain conditions, depression, and OCD. The investigators would like to evaluate the impact of rTMS on the patient's overall perception of change, particularly on the clinical symptoms of motor FND. Secondary objectives include evaluating the overall effect on symptoms from the clinician's perspective, the effect on quality of life, on depressive and anxiety symptoms and associated dissociation, as well as evaluating any changes in the sense of agency and identifying the side effects of rTMS treatment.

Outcome Measures

Primary Outcomes (1)

  • Difference in PGIC (Patient Global Impression of Change) score before versus after treatment.

    The aim is to measure the impact of a course of thetaburst rTMS targeting the rTPJ on the patient's overall impression of change. 5 days before the treatment patients are assessed for all aspects of patients' health using the PGIC. Patients take the test again on the last day of the treatment and again one month after the end of treatment. Score ranges from 1 to 7, the bigger the score, the better the change is.

    From enrollment to the end of the data collecting process : 1 month and 3 weeks

Secondary Outcomes (11)

  • Difference in CGI-I (Clinical Global Impressions - Improvement) score before versus after treatment

    From enrollment to end of data collecting : 1 month and 3 weeks

  • Difference in CGI-Severity (CGI-S) score before versus after treatment.

    From enrollment to the end of the data collecting process : about three months

  • Difference in Simplified-functional movement disorder rating scale (S-FMDRS) score before versus after treatment

    From enrollment to the end of the data collecting process : about three months

  • Difference in MADRS (Montgomery-Asberg Depression Rating Scale) score before versus after treatment

    From enrollment to the end of the data collecting process : about three months

  • Difference in Fatigue Severity Scale (FSS) score before versus after treatment

    From enrollment to the end of the data collecting process : about three months

  • +6 more secondary outcomes

Interventions

Patients receive 40 sessions of intermittent theta burst stimulation of the right TPJ over 10 days (4 sessions per day). The right TPJ is located using neuronavigation.
