Abstract

Tension-type headache (TTH) is the most common form of primary headache. The aim of the review is to analyse research on epidemiology and triggers of TTH. The search for full-text articles in Russian and English languages published within the past decade was performed in E-Library, PubMed, Springer, ClinicalKey and Google Scholar databases. A total of seven Russian and forty-two foreign epidemiological studies have been analysed. Thus, the global prevalence of TTH amounts to 32% (4.4% among these cases are chronic TTH). In Russia, its prevalence is 52.4%. The leading TTH triggers are stress and anxiety-depressive disorders. Insomnia, clinical and meteorological conditions, the ethnos and culture are possible triggers as well. Despite the high occurrence of this primary form of headache in clinical pictures of nervous diseases, it remains insufficiently considered to the date. The issue of TTH requires further investigation.
