- Abstract
Background and purpose: Cognitive dysfunction has been observed following recovery from COVID‐19. To the best of our knowledge, however, no study has assessed the progression of cognitive impairment after 1 year. The aim was to assess cognitive functioning at 1 year from hospital discharge, and eventual associations with specific clinical variables. Methods: Seventy‐six patients (aged 22–74 years) who had been hospitalized for COVID‐19 were recruited. Patients received neuropsychological assessments at 5 (n = 76) and 12 months (n = 53) from hospital discharge. Results: Over half (63.2%) of the patients had deficits in at least one test at 5 months. Compared to the assessment at 5 months, verbal memory, attention and processing speed improved significantly after 1 year (all p < 0.05), whereas visuospatial memory did not (all p > 0.500). The most affected domains after 1 year were processing speed (28.3%) and long‐term visuospatial (18.1%) and verbal (15.1%) memory. Lower PaO2/FiO2 ratios in the acute phase were associated with worse verbal long‐term memory (p = 0.029) and visuospatial learning (p = 0.041) at 5 months. Worse visuospatial long‐term memory at 5 months was associated with hyposmia (p = 0.020) and dysgeusia (p = 0.037). Conclusion: Our study expands the results from previous studies showing that cognitive impairment can still be observed after 1 year. Patients with severe COVID‐19 should receive periodic cognitive follow‐up evaluations, as cognitive deficits in recovered patients could have social and occupational implications.
