Popis: Abstract Background Initial evidence have shown the short-term efficacy of sTMS in the acute and preventive treatment of migraine. It is unknown whether this treatment approach in the long-term is effective and well tolerated in difficult-to-treat migraine. Methods This is a prospective, single centre, open-label, real-world analysis conducted in difficult-to-treat patients with high-frequency episodic migraine (HFEM) and chronic migraine (CM) with and without medication overuse headache (MOH), who were exposed to sTMS therapy. Patients responding to a three-month sTMS treatment, continued the treatment and were assessed again at month 12. The cut-off outcome for treatment continuation was reduction in the monthly moderate to severe headache days (MHD) of at least 30% (headache frequency responders) and/or a ≥ 4-point reduction in headache disability using the Headache Impact test-6 (HIT-6) (headache disability responders). Results One hundred fifty-three patients were included in the analysis (F:M = 126:27, median age 43, IQR 32.3–56.8). At month 3, 93 out of 153 patients (60%) were responders to treatment. Compared to baseline, the median reduction in monthly headache days (MHD) for all patients at month 3 was 5.0 days, from 18.0 (IQR: 12.0–26.0) to 13.0 days (IQR: 5.75–24.0) (P = 0.002, r = − 0.29) and the median reduction in monthly migraine days (MMD) was 4.0 days, from 13.0 (IQR: 8.75–22.0) to 9.0 (IQR: 4.0–15.25) (P = 0.002, r = − 0.29). Sixty-nine out of 153 patients (45%) reported a sustained response to sTMS treatment at month 12. The percentage of patients with MOH was reduced from 52% (N = 79/153) at baseline to 19% (N = 29/153) at month 3, to 8% (N = 7/87) at month 12. There was an overall median 4-point reduction in HIT-6 score, from 66 (IQR: 64–69) at baseline to 62 at month 3 (IQR: 56–65) (P
