The present study revealed that in YOUNG adults, university students, without other comorbidities, there can be significant long-lasting cognitive impairments TWO YEARS after COVID-19 infection."
➡️"Specifically, verbal working memory was significantly impaired, and a lower performance was detected in divided attention and response inhibition.”
