abstract

  • OBJECTIVE: To evaluate rTMS safety and efficacy (in term of headache intensity and frequency reduction and improvement in quality of life) in Chronic Migraine. BACKGROUND: Chronic migraine (CM) is a disabling condition and a challenging therapeutic problem since prophylactic drugs often have inadequate response or unacceptable side effects. A few pilot studies have explored the possibility of applying repetitive transcranial magnetic stimulation (rTMS) in migraine for acute or chronic treatment with controversial results. DESIGN/METHODS: Thirty patients (median age 34 years, 70% female), affected by CM -resistant to preventive pharmacological therapies and in clinical stability in the previous 3 months- participated to the study. rTMS was applied to prefrontal areas at 110% motor threshold intensity and 20 Hz frequency. Three rTMS sessions per week were performed for six weeks with a follow-up visit at 4, 8, 12, 24 weeks, after end of treatment. Patients underwent headache diary assessment, MIDAS, BDI, SF36. RESULTS: No side effects were evident during the study. Ten patients presented with a significative reduction (50%) in headache days (p CONCLUSIONS: The use of rTMS could be a major step forward in CM treatment, particularly in patients where available drugs are ineffective, poorly tolerated or contraindicated rTMS may be able in modulating the activity of cortico-subcortical and cortico-cortical pathways involved in pain control.
