What this trial studies

This study aims to evaluate the effectiveness of intermittent theta burst stimulation (iTBS) targeting the left dorsolateral prefrontal cortex in patients diagnosed with functional movement disorders (FMD). Participants aged 18 to 80 will be randomly assigned to receive either active or sham brain stimulation over five consecutive days. The study will assess changes in motor symptoms using the Functional Movement Disorder Rating Scale, as well as mood symptoms and neuroimaging outcomes. Baseline assessments will include neurological exams, questionnaires, urine tests, and brain MRIs.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 diagnosed with functional movement disorder by a neurologist.

Not a fit: Patients with current psychosis, active suicidal ideation, or significant neurological disorders other than FMD may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve symptoms and quality of life for patients suffering from functional movement disorders.

How similar studies have performed: Other studies using transcranial magnetic stimulation have shown promise in treating various neurological conditions, suggesting potential for success in this novel application.
