Brain fog now = cognitive dysfunction


Senior Member

I read recently that Brain fog is now called cognitive dysfunction

much better name for it - POTSies, EDSers, and PWME all seem to have it
FM people called it fibro fog

this is a better name IMO

Anyone agree ...a good new term or not descriptive enough?
