Objective: To evaluate the course of symtoms and quality of life of migraine patients after treatment with traditional Chinese medicine. Design: Prospective observational study with 12 months follow-up. Patients: 138 consecutive patients diagnosed by a neurologist to have migraine headaches. Intervention: Complex in-patient treatment with traditional Chinese medicine including acupuncture and Chinese drug therapy. Outcomes: Number of days with headaches per month, number, intensity and duration of migraine attacks, concomitant symptoms, quality of life, global assessment and days off work. Results: The number of days with headaches per month decreased from 9 (median) at baseline to 4 at discharge and was 3 at 12 months. Also, for the other outcomes a clear improvement was seen with a slight wash-out tendency in follow-up. Conclusion: The observed patients with long-lasting migraines had a marked benefit from an in-patient treatment with traditional Chinese medicine.
