A small (I hope) hijacking. I've been reading more about Dr. Graham, who first provided the "leonine" characterization. Just thought these quotes about women were worth mentioning.
"It's a man's disease," says Dr. Graham, and women who are afflicted with cluster headache tend to "act mannishly." What's new on heads and their aches? (This article recounts a couple of 1977 talks about CH at a conference. On one hand, they're pretty cringeworthy, and on the other they at least show some folks trying to figure out what to do about CH. (CH was considered just a subdivision of migraine until the 1960s -- which, depending on your age, might seem like a long time ago or pretty recent.) (In 1960, 5% of medical students were women.))
This is from 2006. I think it still took a long time after that to really acknowledge that many women have CH (and many doctors still don't seem to know that), but she (the author) was trying, at least. "Cluster headache is a notoriously painful and dramatic disorder. Unlike other pain disorders, which tend to affect women, cluster headache is thought to predominantly affect men. Drawing on ethnography, interviews with headache researchers, and an analysis of the medical literature, this article describes how this epidemiological “fact”—which recent research suggests may be overstated—has become the central clue used by researchers who study cluster headache, fundamentally shaping how they identify and talk about the disorder. Cluster headache presents an extreme case of medicalized masculinity, magnifying the processes of gendering and bringing into relief features of the world whose routine operation we might otherwise overlook."
