The Americas - North America
The burden of headache is well-established in the United States but not in Mexico.
There may be other important objectives in the United States. These are being discussed with the Special Interest Group for Underserved Populations of the American Headache Society.
The Americas - Central America
Burden-of-headache data exist in Central America but are of questionable quality. At least one new study is needed.
Guatemala offers the best opportunities, with a majority indigenous Mayan population. The neurology training programme at Universidad de San Carlos, under the direction of Dr Henry Stokes, covers the whole country, and many neurologists from neighbouring countries are trained there.
Opportunity may also exist in Belize and Cuba.
Costa Rica is said to have the best-developed health-care system in Central America.
The Americas - South America
Opportunities for studies exist in Brazil and perhaps Colombia.
Brazil is a priority country because of its size, and it is moderately well-resourced. Good prevalence (but not burden) data exist in Brazil. A new study is needed to supplement the epidemiological data.
