Introduction: Patients with chronic daily
headache (CDH) are prone to use many drugs to abort attacks.
Medication overuse must be interrupted before introducing a
Methods: Sixty-one patients suffering from CDH with
drug overuse entered the study. They underwent inpatient drug
withdrawal. Then they were divided into two groups: group A
patients underwent only preventive pharmacological treatment;
group B patients were treated by pharmacological treatment
associated to behavioral therapy by EMG-biofeedback-assisted
relaxation (eight sessions). Patients were followed for a period of
3 years. Clinical improvement was evaluated by comparing data from
the headache diary, the month before withdrawal vs. the month before
the last follow up visit.
Results: At the 3-year follow up, a reduction in
number of days with headache per month was observed in both groups.
Post-treatment data showed a significantly higher reduction in group
B vs. group A for number of days with headache per month, as well as
for the number of symptomatic drugs per month.
Conclusions: Our data suggest that, when biofeedback
treatment is associated to pharmacological preventive therapy in CDH
patients with drug overuse, patients show better clinical results
(reduced headache frequency and drug consumption) considering a
long follow up period after drug withdrawal.
