Einige neurokognitive Defizite von Covid-19 können Jahre dauern, so die Studie schlägt vor | Trotz 3,5 Jahren erheblicher Verbesserungen in den meisten mentalen Funktionen erlebten einige Teilnehmer weiterhin Defizite in mentaler Geschwindigkeit und flexibles Denken.

From the article: For people struggling with post-COVID “brain fog,” new findings suggest that cognitive recovery is possible, though it may take years. A large-scale study recently [published](https://doi.org/10.1016/j.bbih.2025.101093) in Brain, Behavior, & Immunity – Health tracked cognitive changes over three and a half years and found significant improvements in most mental functions. Yet even with this progress, some participants continued to experience deficits in mental speed and flexible thinking.

Since the early days of the COVID-19 pandemic, patients have reported lingering symptoms such as mental slowness, forgetfulness, and trouble concentrating—often described collectively as “brain fog.” While several studies have examined the short-term impact of COVID-19 on brain function, little was known about how these symptoms evolve over several years.

Previous research has offered a mixed picture. Some studies have suggested that cognitive symptoms may improve within a year, while others point to longer-lasting effects, especially in people who were hospitalized. Many of these studies, however, relied on self-reported symptoms or brief online tests, and few used comprehensive in-person assessments with validated neuropsychological tools. Moreover, most did not include diverse or younger populations, making it harder to draw conclusions about how widespread or enduring these impairments might be.

Basically from the get-go I’ve been working with the supposition that covid+ is a lifelong condition

And a lot of people still think it’s just like having a cold for a week…
