The efficacy of repetitive transcranial magnetic stimulation in treating patients with chronic daily headache

Abstract

Abstract Background Headache is the most common pain disorder , affecting around 66% of the global population. This study aimed to investigate the efficacy of high-frequency repetitive transcranial magnetic stimulation (rTMS) in treating patients with primary chronic daily headaches (chronic tension-type headache and chronic migraine). Methods Twenty-seven patients participated in the study, divided into 2 groups: a study group (16 patients) and a control group (11 patients). Treatment consisted of 12 high-frequency (5 Hz) real rTMS sessions, delivered over the left dorsolateral prefrontal cortex (DLPFC), whereas sham rTMS was used for the control group. Results Patients of the study group, after real rTMS stimulation, showed a high statistically significant reduction of the measured headache parameters compared to the control group (P value 0.05) and the percentage of improvement was 7.9%. Conclusion High-frequency rTMS is effective in reducing chronic tension headaches and chronic migraine s. This finding runs with the approval of the suggested role of DLPFC in pain control. This might open opinions for new treatment strategies in tension-type headache and migraine prevention.
