Tension-type headache: an update on mechanisms and treatment

Tension-type headache represents one of the most costly diseases in modern society because of its very high prevalence. Very little research on this disease has actually been carried out, and knowledge about key pathophysiological issues such as the nature and site of the noxious stimulus is surprisingly limited. As a result of this and the lack of scientific interest from the medical field, treatment is widely non-specific, very often ineffective and consists mainly of simple analgesics. The only new strategy is the pericranial injection of botulinum toxin. If current progress in our understanding of the mechanisms of tension-type headache continues, this may lead to greater scientific interest and the development of more specific and more effective drugs in the future.
