Robert Whitfield MD explains patient-reported "brain fog" and a wide range of associated, multisystem symptoms. Patients describe severe memory problems (e.g., not remembering their children’s names) alongside joint and muscle pain, insomnia, anxiety, depression, headaches, skin rashes, and peripheral numbness/tingling; Whitfield notes this breadth makes cases confusing to clinicians.
I think the most important thing that I learned from our patients is what brain fog is. Brain fog was very confusing to me because I didn't quite understand it. So I relied on our patients to explain it. And one of them in the chat was, I was typing to them about it, and they said they couldn't remember their children's names. But other things like joint pain and muscle pain, problems with insomnia, anxiety, depression, headaches, skin rashes, numbness and tingling in the arms and legs. If you can think of a system, you can find a symptom. There's not something that's not affected, and that's Siobhan. That's why it's so confusing to doctors when they meet somebody and they have this list of symptoms that seems to reflect a problem in every system.
