Condition: Tardive Dyskinesia · Repetitive Transcranial Magnetic Stimulation · Sponsor: Peking University Sixth Hospital
\# Brief Summary (English Version) Tardive Dyskinesia (TD) is a hyperkinetic movement disorder induced by long-term use of dopamine receptor blockers and related drugs. Characterized by involuntary spasms or choreiform movements involving the tongue, lower face, jaw, and limbs (persisting for at least several weeks), TD causes irreversible neurological damage that persists even after discontinuing the causative drugs, significantly impairing patients' functional outcomes. rTMS is a non-invasive neuromodulation technique: time-varying currents in a coil generate magnetic fields that penetrate the scalp and skull to act on brain neurons, inducing depolarization, neural network activation, neurotransmitter release, metabolic changes, and gene expression, thereby producing physiological effects \[9\]. In recent years, rTMS has gained attention for treating movement disorders (e.g., Parkinson's disease, motor neuron disease, dystonia, essential tremor, Huntington's disease) due to its non-invasiveness, high safety, and repeatability. Studies have reported that rTMS can significantly improve motor symptoms in TD patients \[10, 11\]; however, existing research is limited by small sample sizes, conventional treatment parameters, large inter-individual variability, and unclear long-term efficacy. rTMS efficacy in TD is strongly influenced by parameters including stimulation targets, localization methods, sequences, and cycles. Optical navigation (using personalized MRI) is the most …
