This article presents secondary headache syndromes caused by life-threatening disease as well as symptomatic headaches requiring immediate treatment to prevent irreversible deficits. Clinical signs and symptoms indicating a secondary headache syndrome are summarized in the so-called SNOOP list (SNOOP: systemic symptoms, neurological symptoms, acute onset, older patients and previous history). The main topic of this publication is the diagnostic procedure, with a discussion of the pitfalls of computed tomography and magnetic resonance imaging investigations and the specificities of other methods such as lumbar puncture and duplex sonography.

Episodic tension type headache is considered to be the most prevalent primary headache. If tension type headache occurs on more than 15 days per month for at least 3 consecutive months, it is classified as chronic tension type headache. ⋯ In the paper, we discuss how the differential diagnosis can be more specific and which therapy is supported by the literature. In addition, we discuss differences and similarities of tension type headache and migraine and a possible similar pathophysiology of both (convergence hypothesis).
