EHMTI-0088. Prediction of treatment response in chronic daily headache patients (a prospective study).

The prevalence of chronic daily headache (CDH) is 4-5% in general population. In headache clinics about 40% patients have CDH and 50-82% of them overuse acute drugs. Combining pharmacological and behavioural therapies can increase effectiveness of treatment, but predictive factors of treatment response are still discussed.
