The study on neurological sequelae in ICU and non-ICU COVID-19 survivors raises important findings, particularly regarding the higher prevalence of microbleeds in ICU patients. However, the lack of significant differences in cognitive dysfunction between ICU and non-ICU groups despite observable brain abnormalities warrants further investigation. I don`t understand why cognitive dysfunction did not correlate with neuroimaging results!
Could this suggest potential confounding factors such as comorbidities, treatment variables, or the limited sensitivity of screening tools like MoCA?
Further clarification by the authors on the implications of these results, particularly in terms of refining diagnostic criteria and expanding neuropsychological assessments to better capture post-COVID cognitive effects is highly appreciated.
