[Diagnosis and treatment of head and facial pain].

The symptom headache is very frequent. Most frequently headache is the leading symptom of a primary headache syndrome such as migraine or tension-type headache. Sometimes it is caused by another disease. In everyday clinical practice it is important to diagnose and treat primary headaches properly. It is even more important not to miss a secondary headache, which is rare, but if misdiagnosed could conceal life-threatening conditions. This review provides an overview of the clinical picture, diagnostic procedures and treatment strategies of frequent headache syndromes such as migraine, tension-type headache, medication overuse headache, trigeminal autonomic cephalgias and trigeminal neuralgia. This is followed by a brief summary on symptomatic headache caused by non-neurological diseases as well as on diagnostic procedures and management of headache in the emergency situation.
