According to the latest scientific standards, there are more than 300 different forms of headache, which are defined in the International Headache Society (IHS) and are differentiated according to fixed criteria. These must first and foremost be correctly diagnosed in order to then propose an individual therapy tailored to each patient individually. A categorisation is made between primary and secondary headaches.

The primary headaches: No cause is known for primary headaches. Primary headaches are an independent disease and include migraines, tension headaches, cluster headaches without structural lesions, e.g. caused by cold, cough or great effort.

The secondary headaches: In the case of secondary headaches, a cause is always known. Secondary headaches occur as a result of other diseases, such as head injuries, meningitis or alcohol consumption.
