Persistent brain fog, hair loss highlighted in long-COVID studies

The first study, by University of Oslo researchers in Norway, was published yesterday in Open Forum Infectious Diseases. The team used four computer-based cognitive tests from the Cambridge Neuropsychological Test Automated Battery to assess 75 adult COVID-19 patients' cognitive function 13 months after release from a single hospital. Included patients were, on average, 55.7 years old and were admitted to the hospital up to June 2020. The four tests were delayed matching to sample (DMS) (testing short-term memory, visuospatial processing, learning, and attention), the One-touch Stockings of Cambridge (OTS) test (executive function), rapid visual-information processing (RVP) (sustained attention), and spatial working memory and strategy (SWM).
