there may possibly be a connection between ancestral origin and a predisposition to cluster headache
still real early in the game to say for sure yes or no
if it's "ethnic" it may have more to do with global area of origin than race
(of course, you could loop back and say the two go together - that's a yes & no, eh ?)
I would like to know if the %of cluster patients who are african-american is approx. the same as %in gen'l pop.
NOT because of skin color, but because of latitude of ancestral origin
Asia is a tougher question because there are asian ethnic stocks at all latitudes, would be REALLY tough to sort out
among european ancestral peoples, it seems there is a strong tendency for one or both parental ancestral lines to be from northern areas
eg: british isles, scandinavia, germanic etc
seems far fewer from southern cultures
suspect there MAY be a latitude-connected, seasonal light rhythym coponent to the puzzle
keep thinking on it & PLEASE let me know what you come up with, this is a pet area of inquiry for me
