The author of a new study discussed the harmful effects on “long Covid” patients, people whose symptoms persist for months after an initial infection.

“Our work, and the work of others, has shown that this affects people’s ability to make plans, synthesize information, and go about their daily work activities,” said David Putrino, director of rehabilitation innovation at Mount Sinai Hospital in New York. “They suffer from great memory loss and inability to form new memories, and difficulty speaking. This is a very debilitating condition with serious cognitive impairment.”

In Putrino’s study, researchers examined how long Covid can impair people’s ability to work and found that almost half of all “long-distance drivers” surveyed stated that they would not be able to return to full employment. The study also found that nearly two-thirds of long-term Covid patients report “brain fog,” which includes memory loss.

Putrino told CNBC’s “The News with Shepard Smith” that Covid has long been a “very real problem” and that more attention needs to be paid to the long-term care of affected patients.

“It affects people of all ages and it doesn’t seem to discriminate against who it knocks down after an acute event,” Putrino said. “We have to organize and we have to start involving government groups in the long-term care of patients who have now been sick for over a year with no real end in sight.”
