One of Long Covid’s worst symptoms is also its most misunderstood (12 September 2022)

Summary

On 25 March 2020, Hannah Davis was texting with two friends when she realized that she couldn’t understand one of their messages. In hindsight, that was the first sign that she had COVID-19. It was also her first experience with the phenomenon known as “brain fog,” and the moment when her old life contracted into her current one. She once worked in artificial intelligence and analysed complex systems without hesitation, but now “runs into a mental wall” when faced with tasks as simple as filling out forms. Her memory, once vivid, feels frayed and fleeting. Former mundanities—buying food, making meals, cleaning up—can be agonisingly difficult. For more than 900 days, while other long-COVID symptoms have waxed and waned, her brain fog has never really lifted.
