Cluster headache
Cluster headache (CHD) is a rare type of primary headache affecting 0.1 % of the population, which is classified in the group of trigeminal autonomic headaches (TAC). CHD is characterized by recurrent attacks of severe, unilateral orbital and periorbital headache with a strong circadian and circular pattern. Typical for CHD and other TAC is the presence of cranial autonomic symptoms during headache attacks such as lacrimation, nasal congestion, miosis. CHD typically occurs in periods lasting mostly 8–12 weeks, which can appear several times a year. Despite the distinct clinical picture, this disease is underdiagnosed. Therefore, knowledge of the symptoms is an essential key for establishing the correct diagnosis.
