Hints on Diagnosing and Treating Headache.

BACKGROUND: Headache, like dizziness, is one of the more common presenting complaints in outpatient care and in the emergency room. More than 200 varieties of headache have been described, and the false impression may arise that the diagnosis and treatment of these syndromes is a highly challenging task.
METHODS: This review is based on pertinent articles retrieved by a selective search in PubMed.
RESULTS: In primary headache, the headache is not a symptom but a disease in its own right. There are four types of primary headache: migraine, tension headache, trigeminal autonomic cephalalgia, and other primary headache disorders. By definition, the physical examination is normal, including the neurological examination. Secondary headache, in contrast, is a symptom of another disease (e.g., a tumor or cerebral hemorrhage). Triptans and nonsteroidal anti-inflammatory drugs (NSAID) are the drugs usually given for the acute treatment and prophylaxis of migraine. In tension headache, NSAID are given acutely, and tricyclic drugs for prophylaxis. There are various options for the treatment of trigeminal autonomic cephalalgia syndromes such as cluster headache and paroxysmal hemicrania. For group 4 headaches (other primary headache disorders), the treatment must be chosen on an individual basis; indomethacin is often effective.
CONCLUSION: If the patient is clearly suffering from none of the four types of primary headache, the problem must be a headache of a secondary nature, potentially reflecting a dangerous underlying disease. The treatment of headache is usually successful and thus highly rewarding for physicians of all medical specialties.
