Obviously not the same, *but* @Radiolab did just report that Woodrow Wilson prob had the Spanish flu in 1919 during WW1 peace talks, w the 'extremely common' symptom of mental disorientation, just before caving on the Treaty of Versailles.

The British Prime Minister referred to Woodrow Wilson's paranoia and delusions from what was probably the Spanish flu, as a "nervous and spiritual breakdown," from which an aide said he'd never fully recovered. https://www.wnycstudios.org/podcasts/radiolab/articles/dispatches-1918

Woodrow Wilson went back to negotiating the end of WW1 at the Paris Peace Conference as a different and weaker man after what was prob the Spanish flu, "giving in on this idea to go light on Germany," and then "Germany was pretty much eviscerated."
