Why does Long COVID brain fog seem to affect more patients in the US? (Hint: it’s not what it seems!) 🧠
A recent Northwestern University study surveyed 3,100 long COVID patients from around the world. 🌍
They interviewed patients from:
-Chicago US -Medellín, Colombia -Lagos, Nigeria -Jaipur, India
Surprisingly, they found that patients in the US reported symptoms such as brain fog and mental health effects at much higher rates than patients in the other cities.
86% of non-hospitalized patients in the U.S. reported brain fog. By contrast, brain fog was reported by:
-63% of patients in Nigeria -62% in Colombia -and just 15% in India.
When it comes to anxiety or depression, the difference was even more clear:
Nearly 75% of non-hospitalized patients in the U.S. reported depression or anxiety.
By contrast, these symptoms were reported by:
-40% of Colombian patients -Fewer than 20% of Nigerian and Indian patients
Researchers suspect these differences are not biological. Rather, they believe cultural differences affect who is likely to feel comfortable reporting mental health symptoms to researchers.
In the US, while things are far from perfect, there is more acceptance around mental health. By contrast, patients in other parts of the world are more likely to experience stigma, meaning they’re less likely to feel comfortable disclosing mental health symptoms to researchers.
These cultural nuances are very important for doctors, researchers, and organizations to keep in mind.
We know there are millions of Long COVID patients all over the world in need of proper diagnostics and treatment - and there are likely significant numbers of patients who are not comfortable speaking up about all of the symptoms they’re experiencing.
We can help by continuing to raise awareness about Long COVID, so that doctors internationally are aware of these symptoms and can be on the lookout for patients who need help.
Papers like this one are very important to raise awareness of the scope of the problem. Thank you to Jimenez et al. for this important work!
