Viagra for the brain

Here's a reminder that "chronic fatigue" is a very vague diagnosis:…

Some quotes:

"Brain scans of people with Sneddon's [Syndrome] show reduced blood flow to the brain ...

"In addition to a daily blood thinner and other medications, O’Leary takes Revatio, which is essentially Viagra prescribed at smaller doses and for a different purpose than erectile dysfunction. In O’Leary’s case, it appears to dilate blood vessels in the brain and improve her mental functioning."

(Of course, besides whatever weird thing causes Sneddon's Syndrome -- it's a rare disease, distinguished by "bluish, net-like mottling of the skin" -- there might also be some infectious agent involved.)


Interesting, Norman. Permanent livedo reticularis often implies vasculitic disease; I saw it quite commonly in persons with raised C. pneumoniae IgA antibodies.

Though temporary LR can be benign (cold water bathing will bring it on, particularly in young women) permanent LR can be associated with a whole raft of clinical syndromes.
