Rhythmic transcranial magnetic stimulation in the treatment of cervical dystonia and comorbid mental disorders

Cervical dystonia (CD) is a common form of movement disorder with a high incidence of comorbid mental disorders. Rhythmic transcranial magnetic stimulation (rTMS) is effective in depression and other mental disorders, but its efficacy in CD with comorbid mental disorders has been poorly studied.Objective: to investigate the efficacy of rTMS in CD and comorbid mental disorders.Material and methods. Seventeen patients with CD underwent a course of 10 rTMS sessions (protocol: 1 Hz, 600 pulses to the left primary motor cortex). The severity of mental disorders, quality of life and severity of cervical dystonia were assessed using the HADS, SF-36 and CDQ-24 scales.Results. After transcranial magnetic stimulation treatment, a significant reduction in anxiety (from 12.2±4.1 to 6.3±2.1 points; p
