3 Diagnostic aspects II Consider fears and worries Parents Patient Successful migraine therapy Reduces headache duration headache frequency headache intensity Relieves associated symptoms nausea, vomiting photo- and phonophobia aura other symptoms

4 Successful migraine therapy Improves the quality of life Treatment of migraine Acute therapy Non-pharmacological Pharmacological Prophylaxis Non-pharmacological Pharmacological

5 When do we need non- pharmacological treatment? Always When do we need pharmacological treatment? Sometimes

6 Therapeutic decision I The patient's symptoms direct the decision to admininister pharmacological treatment the choice of the drug. Administering a drug without considering the patient's symptoms may cause treatment failure and other problems. Therapeutic decision II Prescribing no drug may be better than prescribing the wrong drug. There is no drug without potential risks. Even homeopathy may harm: The child learns to grab for a drug instead of acquiring appropriate coping strategies. There is no evidence that homeopathic treatment is effective in migraine and tension-type headache.
