Dr. Allison P. Navis, a neuroinfective disease specialist at Mount Sinai Health System in New York City who was not involved in the study, said about 75 percent of her 200 patients had problems like “depression, anxiety,” or irritability after Covid some mood symptoms. “
The study participants were predominantly white and 70 percent were women. Dr. Navis and others said the lack of diversity most likely reflected the demographics of people who were able to seek help relatively early in the pandemic, rather than the full range of people affected by neurological symptoms after Covid.
“Especially in New York City, most of the patients who have Covid are black people and Medicaid patients, and these are absolutely not the patients you see at the Post-Covid Center,” said Dr. Navis. “The majority of patients are white, often they have private insurance, and I think we need to figure out a little more about what’s going on with these differences – if it’s just a lack of access or if it’s symptoms in people to be rejected by color or if it is something else. “
In the Northwestern study, Dr. Koralnik that only half of the participants tested positive for the coronavirus as all coronavirus tests were difficult to obtain at the start of the pandemic but all had the initial physical symptoms of Covid-19.
