Tension-type headache represents one of the most costly diseases in modern
society because of its very high prevalence. Very little research on this d
isease has actually been carried out, and knowledge about key pathophysiolo
gical issues such as the nature and site of the noxious stimulus is surpris
ingly limited. As a result of this and the lack of scientific interest from
the medical field, treatment is widely non-specific, very often ineffectiv
e and consists mainly of simple analgesics. The only new strategy is the pe
ricranial injection of botulinum toxin. If current progress in our understa
nding of the mechanisms of tension-type headache continues, this may lead t
o greater scientific interest and the development of more specific and more
effective drugs in the future. Curr Opin Neurol 13:285-239 (C) 2000 Lippin
