US guidelines on neuroimaging in patients with non-acute headache: a commentary.

The US Headache Consortium is a group of 14 US doctors (mainly academic neurologists) who aim to “develop scientifically sound, clinically relevant practice guidelines on chronic headache in the primary care setting”. The consortium has produced several sets of guidelines, endorsed by the American Academy of Neurology and several other relevant US medical academic societies. These include the guidelines on neuroimaging of non-acute headache patients. As far as I am aware, these are the only available guidelines addressing this issue. Nonacute (or chronic) headache is defined as all headache syndromes lasting for at least four weeks, and the “primary care setting” in the USA refers to patients seen in an outpatient setting by a family doctor, a general physician or a specialist.
