Study shows possible link between smell loss from COVID and long-lasting cognitive issues – NBC 7 San Diego

A study by Argentinian researchers who worked with the Alzheimer’s Association Consortium suggests that persistent loss of smell may possibly predict cognitive impairment, especially when dealing with long COVID.

Holly Schmitz, a San Diego resident who has suffered from COVID for a long time since December, said the impacts of the virus have not only impacted her exercise endurance, but even her way of thinking.

“I had two weeks where it was a little bit better,” Schmitz said.

One of her main symptoms, seven months after contracting the coronavirus, is brain fog, something she was able to measure through apps on her phone.

“You know, I play these little games on my phone,” Schmitz said. “It’s like Scrabble, little game, choose the words, and I went back and I could see like this huge drop in my scores because I had, like, a year of information, and I think , ‘No, it’s real.’ ”

The recent study that suggests the link between loss of smell and cognitive impairment followed 766 adults aged 55 to 95 with COVID-19 over the course of a year. According to his findings, about two-thirds of the participants experienced functional memory impairment as a result of the disease. In the study, it was stated that statistical analysis showed that persistent loss of smell was a significant predictor of cognitive impairment.

UC San Diego physician and infectious disease specialist Dr. Lucy Horton had this to say about the study: “I don’t think you can say that loss of smell leads to cognitive impairment. . I think what they were showing in this study was a combination of those two symptoms.”

As more studies continue to be published on the impacts of COVID-19, locals like Roger Modeste are unconcerned about the virus.

“Maybe it worries me: that we panic again like we did a year ago and lock ourselves in,” Modeste said. “Really not good for the environment, for our communities.”

Meanwhile, Horton said when it comes to long COVID, she believes there needs to be more attention, funding and effort to diagnose, manage and treat patients with long COVID.
